EVM WARNINGS AND RESTRICTIONS
It is important to operate this EVM within the specified input and output ranges described in
the EVM User’s Guide.
Exceeding the specified input range may cause unexpected operation and/or irreversible
damage to the EVM. If there are questions concerning the input range, please contact a TI
field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or
possible permanent damage to the EVM. Please consult the EVM User’s Guide prior to
connecting any load to the EVM output. If there is uncertainty as to the load specification,
please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than
60°C. The EVM is designed to operate properly with certain components above 60°C as long
as the input and output ranges are maintained. These components include but are not limited
to linear regulators, switching transistors, pass transistors, and current sense resistors. These
types of devices can be identified using the EVM schematic located in the EVM User’s Guide.
When placing measurement probes near these devices during operation, please be aware
that these devices may be very warm to the touch.

About This Manual
This manual describes the function and operation of the MSC1200EVM
evaluation module. Throughout this document, the abbreviation EVM and the
termevaluation module are synonymous with the MSC1200EVM. This manu-
al will help you quickly set up the EVM and its accompanying software, so that
you can rapidly test and evaluate the MSC1200. A complete circuit descrip-
tion, as well as schematic diagram and bill of materials, is included.
How to Use This Manual
This manual begins with an introductory chapter which describes the
evaluation module and what it can do. If you are ready to set things up and start
testing, we suggest you read at least the first two chapters. These sections
introduce you to the board and how to configure it for testing the device. Later
chapters go into more detail on the EVM design and how to access its many
features.

1.1 MSC1200 Characteristics
The MSC1200 is a precision 24-bit delta-sigma (∆Σ) analog-to-digital convert-
er with an 8051 microcontroller and up to 8K of flash memory. It has eight fully
differential or single-ended analog input channels. The delta-sigma architec-
ture employed in the MSC1200 enables the device to achieve 22 bits of effec-
tive resolution (0.45ppm RMS noise) at a data rate of 10Hz. It can be pro-
grammed for other data rates up to 1 kHz that have lower effective resolution.
In addition to the standard 8051 peripherals and functions, the MSC1200
includes a 32-bit accumulator, basic SPI/I2C interface, 16-bit PWM output,
4/8K data flash memory, 1,280 bytes of data RAM, UART and dual DPTR
registers.
The MSC1200 has an enhanced 8051 core which only requires four clock
cycles per machine cycle. It has extra timers as well as watchdog, brownout
and low voltage detect circuits. Additionally, it features power management
control and hardware breakpoint registers.

Analog Inputs/Outputs
1-4
During normal operation, programs are developed on the PC and then down-
loaded into the MSC1200 for execution. The primary development environ-
ment is Raisonance for assembly and C language programming. There is also
a Basic interpreter available from MDL−Labs.
1.3 Analog Inputs/Outputs
Analog input is supplied through the 11-way screw terminal block J4. The nine
analog inputs (AN0−7, AINCOM) are connected to the MSC1200 through a
100Ωresistor. There is also a terminal block for AGND (GND). The inputs have
only the 100Ωresistor to protect against overvoltage.
1.4 Power Requirements
When the MSC1200EVM uses J3 (RS232) connector for communications,
power (5.5V to 15V) must be supplied to J2 (and pins 2-3 of JMP1) for proper
operation.
A 9V wall mount power supply is included with the MSC1200EVM to provide
this power.
When using USB communications, power is provided from the USB connector
(J1) and pins 1-2 are connected on JMP1.
1.5 Host Computer Requirements
The Keil or Raisonance software development environments are designed to
run on a PC running any Windows platform (Windows 9x/NT/2K/XP).
Minimum operating system requirements are:
-IBM-compatible 486 PC or higher
-64MB RAM
-20MB available hard disk space
-CD-ROM drive
-Available RS232 or USB serial port

Unpacking the EVM

2.1 Unpacking the EVM
After unpacking the MSC1200EVM kit, verify that you have received all of the
items listed here:
-MSC1200EVM board
-9V wall mount power supply
-9-pin D-sub male-female 2m serial cable
-2m A-B USB cable
-Software CD-ROM
-This user guide
If any of these items are missing, contact Texas Instruments to receive
replacements.
2.2 Default Configuration
Although much of the MSC1200EVM operation is controlled by the host PC,
some configuration must be done directly on the board, using ten jumpers
(shorting blocks). The MSC1200EVM is configured at the factory as described
in Table 2−1:
Table 2−1.Factory Jumper Settings
Jumper Identifier Description Default Setting
JMP1 5V power supply source (USB) 1−2
JMP2 Digital power supply select (5V) 2−3
JMP4 IDAC 1K Load Resistor 1−2
JMP5 AVDD Power Source (EVM) 1−2
JMP6 AINCOM to AGND Connection 1−2
JMP7 Red LED enable 1−2
JMP8 Yellow LED enable 1−2
JMP9 SPI/I2C Select (SPI) 1−3, 2−4
JMP10 SPI/I2C Clock Source 1−2
For more information about the jumpers, see section 3−1.

2.3 Quick Start
Once the MSC1200EVM has been unpacked from its shipping container, and
you have verified that the board is configured as shown in Table 1, it can be
powered on and tested.
There are two options for supplying power to the EVM: via a USB connection
through the host computer, or from an external wall mount power adapter.
2.3.1 USB Connection
Connect the board to the host PC using the supplied USB serial cable. When
the board is properly powered on, the green power good LED near the power
USB connector will glow brightly.
2.3.2 Wall Power Connection
Connect the board to the host PC using the supplied 9-pin serial cable. Then
power on the board by plugging the wall power adapter into a suitable AC pow-
er source and plugging the barrel plug into the barrel jack on the
MSC1200EVM. (You do not have to connect the serial cable first; it is also
acceptable to apply power to the board first.) When the board is properly pow-
ered on, the two green power good indicator lamps near the power connectors
will glow brightly.
Place the CD-ROM into the PC’s CD−ROM drive. You should then see the
installation screen shown in Figure 2−1.

Figure 2−1.Installation Screen
Select the tools that you want to install. Keil, Raisonance and Wickenhauser
are all C compilers. The Keil and Raisonance tools include a complete IDE with
debug support. The TI Downloader is used to load the compiled HEX file into
the MSC1200EVM.
Install any of the compilers that you wish to use. Also, choose the TI Downloader.
(Note: If you are running Windows NT or Windows 2000, you will need adminis-
trator privileges to install the software.) Follow the instructions displayed by the
installer. When the software is installed, you can select,Explore the CD. You can
also find some example programs in the \Example Programs\MSC1200 directo-
ry.
Once the programs have been successfully installed, they can be executed.
If you examine the HelloWorld project when the Keil uVision2 development
system is run, it will display a title screen; you will see a message like that
displayed in Figure 2−2.

Refer to the Keil documentation and Help menus for more information about
how to interact with the Keil software environment. When a program is
compiled, it can be immediately downloaded into the MSC1200EVM by using
the TI download utility program.
In the Project Menu, select Options for target ‘. . . ‘ Then select the output
tab. You will see a screen like the one shown in Figure 2−3.

Check the box to Create HEX File and Run User Program #1.Then enter the
download command with its parameters in the window. The download.exe file
will need to be in the current directory or the Windows path.
All operands should immediately follow the switch character with no spaces
except between options; for example:
download.exe /Fconv.hex /B9600 /P1
If the filename, crystal frequency or port are not included, then a screen will
prompt for the values.
/Ffile hex file, #H in the Keil environment will substitute the hex file
(required)
/Xfreq MSC1200 Xtal Clock frequency (required)
/Pport PC Comm port 1, 2, 3 or 4 (required)
/Bbaud Download baud rate (standard rates), otherwise − computed
from /Xfreq
/H If this flag is present, the configuration bytes will be erased
/Tbaud This flag requests a terminal window after download; can specify
baud.
/D Debug mode. Displays a terminal window of the command
interactions.
/Epages Specify a partial erase of the flash memory
