COP8 OTP/ROM PROTOTYPING KIT
QUICKSTART MANUAL for COP8-PRO-COB1
INTRODUCTION
The COP8-PRO-COB1 Prototyping Kit
provides a low cost, easy-to-use environment for
quickly starting the development and debugging
of COP8 OTP/ROM applications.
The development environment includes a
Windows IDE, with COP8 Assembler, Linker,
Librarian, Instruction Simulator, and COP8 Code
Generator and C-Compiler demos. Use the
comprehensive documentation and sample source
code to quickly develop and simulate your
application.
Download your code to any COP8 OTP/EPROM
programmer for updating the COP8 device on the
COBALT (COP8 Breadboarding and Learning
Tool) Prototyping/Target board for 10MHz real-
time execution and pin probing. Or you can skip
the OTP/EPROM device, and download to an
optional COP8 Emulator for real-time debugging.

HARDWARE SETUP
No physical connection between the COBALT
board and your PC is necessary, unless you are
using an optional COP8 emulator, or are
planning to interface to an application-driven
serial interface on the COBALT board.
The board, as configured, requires any 8-16v
AC/DC, regulated/unregulated power supply
(including a 9v battery), with a standard 1/8”
barrel-type connector. Optionally, you can
connect a 5v, DC supply directly to the GND
and VCC connections on the target board.
Check that the green power LED is on.
When power is applied with the pre-
programmed COP8SGR7 installed, LEDs 1-8
should begin to flash sequentially. This confirms
that the board is electrically operational, with the
clock running at 10MHz. Pressing the RESET
switch should turn off all LEDs, and when
released, the LEDs should resume flashing.
The board comes with a pre-programmed,
erasable COP8SGR7Q3 40DIP device installed
in the on-board socket. You can use this device,
or any other COP8 OTP device of your choice
(such as the COP8Sax7), in 28 or 40 DIP. 20 DIP
requires an optional device socket. OTP versions
can be sampled for free, and Erasable EPROM
versions can be purchased from National’s web
site.
If you will be using an optional COP8 OTP/ROM
Emulator, remove the COP8 and connect the DIP
emulation cable to the 40 pin socket on the target
board, otherwise you must use an OTP/EPROM
programmer with your PC for re-programming the
erasable COP8SGR7Q3 device.
If your application requires RS232 or EEPROM,
you will have to install the appropriate IC and
interface cables.
You are now ready to develop, download, and
debug code!
NOTE: The COBALT board comes pre-
configured for 5v/10MHz operation, with fixed
LEDs and Switches for I/O, MicroWire Interface
connections, and unstuffed RS232 and EEPROM
locations. Refer to the User’s Manual for details
on customizing the board’s configuration, and
operating voltage/frequency.
DEVELOPING CODE
For more information on developing COP8
code, COP8 architecture, and designing with
COP8SA/SG/AJ/AK devices, refer to our
“COP8 Feature Family User’s Manual”, “COP8SA
Designer’s Guide”, and our “COP8
Assembler/Linker/Librarian User’s Manual.”

Revision 1.0, 8/2001
First, set up your environment for code
development. Refer to the IDE Help files for
information and tutorials. National’s COP8 IDE
supports a complete set of tools, including
Simulator, COP8-EM/DM Emulator Debugger,
Aisys’ DriveWay COP8 (optional), and Byte
Craft C-Compiler (optional).
Options for starting code development:
1) Browse the CD for app notes and existing
source code that match your desired
application. Use and modify as needed.
2) Browse the CD for source code example
modules to build your application in pieces.
(Start with the COP8 Utilities code
samples). Mix and match as needed.
3) Start from scratch using the COP8
Assembler (or optional C-Compiler).
DOWNLOADING CODE
You have two methods of downloading your
simulated code to the COBALT board for test
and debug:
1. Real-time Emulator - Communication
between the COP8-EM/DM emulator and your
PC is via the RS232 interface.
a. Remove the 40DIP COP8SGR7 from the
COBALT board, and connect the emulator
cable to the empty 40 pin DIP socket.
b. From the COP8 IDE, execute the emulator
Debugger software. The debugger is used to
download your source code file into the
emulator, for execution and debug.
2. OTP/EPROM Programmer – A wide
variety of programmers from National and other
third-party vendors are available. The COP8-
PM-00 Engineering Programmer from National
is an ideal solution. In addition to the procedure
below, there are other methods of creating a
programmer .hex file (refer to: AppDM4.PDF):
a. Remove the 40DIP COP8SGR7Q3 from the
COBALT board, and erase for at least 15-30
minutes under a standard UV eraser.
b. Confirm that the ECON is correctly declared
in your assembly source code file.
c. Use the PROMCOP.exe utility to create an
INTEL .hex file. Make sure you add the
ECON directive, so the ECON data is
properly added to the .hex file (The default is
no ECON).
d. Download the resulting INTEL .hex file to any
programmer that supports the COP8SGR740
DIP device.
e. Re-insert the programmed device into the
40DIP socket on the COBALT board.
TARGET DEBUG
After your code is downloaded into the target
COP8, the COBALT target board is ready for
stand-alone operation and test probing. If you
are using a COP8 emulator, then the emulator is
left installed for interactive debugging.
The COBALT target board has a 10MHz crystal
for real-time operation, with an onboard Reset
pushbutton (SW1) for easy Reset/Restart.
LEDs and Switches are provided for I/O
stimulus and visual debug. Test connections for
each of the device’s 40 pins are brought out for
easy probing, or connection to external circuits.
A Microwire/PLUS interface, and an RS232
connector are provided for external serial
communications, along with a variety of I/O
connections and probe points.
If you are not using an emulator, when you are
ready to download another version of the code,
you must remove and erase the COP8, re-program
and re-install in the on-board socket.
