2. About the Daughter Boards
The C8051T60x Development Kit includes two daughter boards: an Emulation Daughter Board (EDB) and an SOIC
Socket Daughter Board (SOIC-DB). The EDB has a C8051F300 device installed, which is a Flash-based device
that can be used for the majority of C8051T60x code development. The SOIC-DB and the QFN-DB (available
separately) are intended to allow both the programming of multiple C8051T60x devices, as well as system-level
debugging of these devices. Once a C8051T60x device has been programmed, it cannot be erased, so it is
advisable to use the C8051F300 for the majority of code development. Refer to Application Note “AN280:
Differences Between the C8051F300 and the C8051T60x Device Family” for more details on how the C8051F300
can be used to develop code for the C8051T60x device family.
3. Hardware Setup
Refer to Figure 1 for a diagram of the hardware configuration.
1. Attach the desired daughter board to the main board at connectors P1 and P2.
2. If using the SOIC Socket daughter board or the QFN Socket daughter board, place the device to be
programmed into the socket.
3. Connect the AC to DC Power Adapter to connector P3 on the main board.
4. Connect the main board to a PC running the Silicon Laboratories IDE using the USB Cable.
Notes:
Use the Reset icon in the IDE to reset the target when connected during a debug session.
Remove power from the main board and remove the USB cable before removing a daughter board from the
main board. Connecting or disconnecting a daughter board when the power adapter or USB cable are
connected can damage the main board, the daughter board, or the socketed device.
Likewise, remove power from the main board and remove the USB cable before removing a C8051T60x device
from the socket. Inserting or removing a device from the socket when the power adapter or USB cable are
connected can damage the main board, the daughter board, or the socketed device.

5.3. Evaluation C51 ‘C’ Compiler
An evaluation version of the Keil C51 ‘C’ compiler is included with the development kit and is installed during IDE
installation. The evaluation version of the C51 compiler is the same as the full professional version except code
size is limited to 4 kB and the floating point library is not included. The C51 compiler reference manual can be
found under the Help menu in the IDE or in the “SiLabs\MCU\hlp” directory (C51.pdf).
5.4. Using the Keil Software 8051 Tools with the Silicon Laboratories IDE
To perform source-level debugging with the IDE, you must configure the Keil 8051 tools to generate an absolute
object file in the OMF-51 format with object extensions and debug records enabled. You may build the OMF-51
absolute object file by calling the Keil 8051 tools at the command line (e.g. batch file or make file) or by using the
project manager built into the IDE. The default configuration when using the Silicon Laboratories IDE project
manager enables object extension and debug record generation.
Refer to Application Note “ AN104: Integrating
Keil 8051 Tools Into the Silicon Labs IDE”
in the “SiLabs\MCU\Documentation\Appnotes” directory on the CD-
ROM for additional information on using the Keil 8051 tools with the Silicon Laboratories IDE.
To build an absolute object file using the Silicon Laboratories IDE project manager, you must first create a project.
A project consists of a set of files, IDE configuration, debug views, and a target build configuration (list of files and
tool configurations used as input to the assembler, compiler, and linker when building an output object file).
The following sections illustrate the steps necessary to manually create a project with one or more source files,
build a program and download the program to the target in preparation for debugging. (The IDE will automatically
create a single-file project using the currently open and active source file if you select Build/Make Project before a
project is defined.)
5.4.1. Creating a New Project
1. Select Project→New Project to open a new project and reset all configuration settings to default.
2. Select File→New File to open an editor window. Create your source file(s) and save the file(s) with a rec-
ognized extension, such as .c, .h, or .asm, to enable color syntax highlighting.
3. Right-click on “New Project” in the Project Window. Select Add files to project. Select files in the file
browser and click Open. Continue adding files until all project files have been added.
4. For each of the files in the Project Window that you want assembled, compiled and linked into the target
build, right-click on the file name and select
Add file to build . Each file will be assembled or compiled as
appropriate (based on file extension) and linked into the build of the absolute object file.
Note: If a project contains a large number of files, the “Group” feature of the IDE can be used to organize.
Right-click on “New Project” in the
Project Window . Select Add Groups to project . Add pre-defined
groups or add customized groups. Right-click on the group name and choose
Add file to group . Select files
to be added. Continue adding files until all project files have been added.

5.4.2. Building and Downloading the Program for Debugging
1. Once all source files have been added to the target build, build the project by clicking on the Build/Make
Project button in the toolbar or selecting Project→Build/Make Project from the menu.
Note: After the project has been built the first time, the Build/Make Project command will only build the
files that have been changed since the previous build. To rebuild all files and project dependencies, click
on the Rebuild All button in the toolbar or select Project→Rebuild All from the menu.
2. Before connecting to the target device, several connection options may need to be set. Open the
Connection Options window by selecting Options → Connection Options... in the IDE menu. First, select
the “USB Debug Adapter” option. The USB Debug circuitry is integrated onto the C8051T60x main board.
Next, the correct “Debug Interface” must be selected.
C8051T60x Family devices and the C8051F300 all use
Silicon Labs “C2” 2-wire debug interface. Once all the selections are made, click the
OK button to close the
window.
3. Click the
Connect button in the toolbar or select Debug → Connect from the menu to connect to the device.
4. Download the project to the target by clicking the Download Code button in the toolbar.
Note: To enable automatic downloading if the program build is successful select Enable automatic con-
nect/download after build in the Project→Target Build Configuration dialog. If errors occur during the
build process, the IDE will not attempt the download.
5. Save the project when finished with the debug session to preserve the current target build configuration,
editor settings and the location of all open debug views. To save the project, select Project→Save Project
As... from the menu. Create a new name for the project and click on Save.
6. Example Source Code
Example source code and register definition files are provided in the “SiLabs\MCU\Examples\C8051T60x”
directory during IDE installation. These files may be used as a template for code development.
6.1. Register Definition Files
Register definition files C8051T600.inc, C8051T600_defs.h and compiler_defs.h define all SFR registers and bit-
addressable control/status bits. They are installed into the “SiLabs\MCU\Examples\C8051T60x” directory during
IDE installation. The register and bit names are identical to those used in the C8051T60x datasheet. The register
definition files are also installed in the default search path used by the Keil Software 8051 tools. Therefore, when
using the Keil 8051 tools included with the development kit (A51, C51), it is not necessary to copy a register
definition file to each project’s file directory.
6.2. Blinking LED Example
The example source files blink.asm and blinky.c show examples of several basic C8051T60x functions. These
include; disabling the watchdog timer (WDT), configuring the Port I/O crossbar, configuring a timer for an interrupt
routine, initializing the system clock, and configuring a GPIO port. When compiled/assembled and linked these
programs flash the green LED on the C8051T600 main board about ten times a second using the interrupt handler
with a timer.

7.1. System Clock Sources
The C8051T60x devices feature a calibrated internal oscillator which is enabled as the system clock source on
reset. After reset, the internal oscillator operates at a frequency of 24.5 MHz (±2%) by default, but may be
configured by software to operate at other frequencies. Therefore, in many applications an external oscillator is not
required. However, if you wish to operate the C8051T60x device at a frequency not available with the internal
oscillator, an external oscillator source may be used. Refer to the C8051T60x datasheet for more information on
configuring the system clock source.
The main board is designed to facilitate the use of external clock sources. To use an external CMOS clock source,
the clock can simply be applied to P0.3. To implement the RC mode option, placeholders for an 0805-packaged
capacitor (C20) and resistor (R18) are supplied on the board. The C (capacitor) clock option can be implemented
by using only the capacitor placeholder (C20). To reduce the amount of stray capacitance on the pin, which could
affect the frequency in either RC or C mode, resistor R12 can also be removed from the board when using C or RC
mode. Refer to the C8051T60x datasheet for more information on the use of external oscillators.
7.2. Switches, LEDs and Potentiometer
Two switches are provided on the main board. Switch RESET is connected to the RESET pin of the C8051T60x.
Pressing RESET puts the device into its hardware-reset state. Switch P0.3 can be connected to the C8051T60x’s
general purpose I/O (GPIO) pin through header J3. Pressing Switch P0.3 generates a logic low signal on the port
pin. Remove the shorting block from the J3 header to disconnect Switch P0.3 from the port pin.
Four LEDs are also provided on the target board. The red LED labeled PWR (D4) is used to indicate a power
connection to the target board. The red/green LED labeled D2 is the run/stop light for the debug circuitry. The red
LED labeled D7 indicates when the VPP programming voltage is being applied to the device (see Section 7.7 for
additional details). Finally, the green LED labeled P0.6 (D1) can be connected to the C8051T60x’s GPIO pin
through header J3. Remove the shorting block from the header to disconnect the LED from the port pin.
Also included on the C8051T60x main board is a 10 kΩthumb-wheel rotary potentiometer, reference number R13.
The potentiometer can be connected to the C8051T60x’s P0.1 pin through the J7 header. Remove the shorting
block from the header to disconnect the potentiometer from the port pin.
See Table 1 for the port pins and headers corresponding to the switches, LEDs, and potentiometer.
7.3. USB Debug Interface (DEBUG / J1)
A Universal Serial Bus (USB) connector (J1) is included to provide the on-board debug and programming interface.
The debug/programming interface is powered through the USB connector, but requires power to the device via the
power connector P3 to be fully functional.

7.4. PORT I/O Connector (J8)
Each of the C8051T60x’s I/O pins, as well as VPP, +3VD, GND, and /RST are routed to header J8. This header can
be used to easily connect to any signal on the device. Table 2 defines the pins for header J8.
7.5. Serial Interface (J2)
A RS232 transceiver circuit and DB-9 (J2) connector are provided on the main board to facilitate serial connections
to UART0 on the C8051T60x. The TX and RX signals of UART0 may be connected to the RS-232 transceiver by
installing shorting blocks on header J3. The RTS and CTS lines do not have a direct connection available to the
C8051T60x, due to limited pin resources on the device. However, these two signals have also been routed through
the transceiver, and are available for wiring on-board at test points near the DB-9 connector. The transceiver shifts
the UART signals to RS-232 levels, and connects to the appropriate pins on the DB-9 connector.
J3[1–2] - Install shorting block to connect UART0 RX (P0.5) to transceiver.
J3[3–4] - Install shorting block to connect UART0 TX (P0.4) to transceiver.
7.6. Analog I/O (J6)
Two of the C8051T60x target device’s port pins are connected to the J6 terminal block. Refer to Table 3 for the J6
terminal block connections.

7.7. VPP Connection (J10)
The C8051T60x devices require a special 6.5 V programming voltage applied to the VPP pin during device
programming. The VPP pin on these devices is shared with P0.2. During programming, the VPP voltage is
automatically enabled when needed. Header J10 is provided to allow the user to disconnect the programming
circuitry from the VPP/P0.2 pin to avoid interfering with the normal application operation of P0.2. When
programming the device, J10 should be shorted with a shorting block. When running normal application code, J10
can be removed. Note that the C8051T600 Emulation Daughter Board does not connect the main board’s VPP and
P0.2 signals, so removing the shorting block is not necessary when using the Emulation Daughter Board.
7.8. Using Alternate Supplies with the C8051T60x Development Kit
For most evaluation purposes, the on-board 3.3 V supply regulator is sufficient to be used as a VDD power supply.
However, in applications where a different supply voltage is desired (for example, 1.8 V), an external supply
voltage can be applied to the board at the analog connector (J6). Depending on the supply and the desired
functionality of the board, it may be necessary to cut the VDD supply voltage trace on the back of the board behind
header J9 (not populated). The following should be considered when supplying a different voltage to the device:
1. When programming a C8051T60x device: The on-board 3.3 V regulator should be used for VDD.
2. If a VDD supply voltage between 2.7 and 3.6 V is desired: The ac to dc power adapter should be disconnected
from P3, and the desired supply voltage can be applied directly to the GND and VDD terminals of terminal block
J6. No board modification is necessary.
3. If a VDD supply voltage between 1.8 and 2.7 V is desired and RS-232 functionality is not required: The ac to dc
power adapter should be disconnected from P3, and the desired supply voltage can be applied directly to the
GND and VDD terminals of terminal block J6. No board modification is necessary.
4. If a VDD supply voltage between 1.8 and 2.7 V is desired and RS-232 functionality is required: The RS-232
transceiver is not specified to operate below 2.7 V. In this case, the trace under header J9 should be cut. Then,
the desired VDD supply voltage can be applied directly to the GND and VDD terminals of terminal block J6, and
the ac to dc power adapter can be connected to P3, to provide 3.3 V to the RS-232 transceiver. In this case, it
may also be necessary to configure the TX pin on the device for open-drain mode, and add a pull-up resistor to
the supply of the transceiver.
