TARGET BOARD DETAILS (see schematics and PCB silkscreen for details)
1. Power - 5-25v DC external power source attached to TP1 and TP5. <5v sources can be directly
attached to the output of the 5v regulator (bypassing the regulator), or a lower voltage regulator can be
installed. The red LED indicates power to the PCB.
2. Breadboard Area - The breadboard area has multi-layer ground and power planes for noise-free digital
and analog circuit operation. Installing J15 and J10 provides a common power/ground . Removing one (or
both) of J15 and J10 allows separate Analog and Digital power and grounds. DGND and AGND test
points are located at the corners of the PCB.
3. Clock Sources - J11-J14 provide flexible clock configurations, with a combination of on-board and
external clock sources.
The jumpers come installed for on-board 10MHz and 32KHz, dual-clock
operation. Other crystal frequencies can be used, or external clocking can be customized.
4. Application Reset Button - A simple reset to the device (SW1). If the Flex bit is Enabled, your
application code will run. If the Flex bit is not enabled, the device will start up in the ISP mode.
(SW1 is also used with SW2 to force a programmed device into the ISP mode.)
5. ISP Reset Button - When J16 is in position 1-2, pushing SW2 connects a 2xVcc voltage to the device
G6 pin. This button is used ONLY for forcing a programmed device into the ISP mode. When J16
is in position 2-3, this button is isolated from the G6 pin, and is not connected to anything.
6. Device Sockets - The three device sockets are connected in parallel, sharing the clock circuits, Reset,
ISP connections, I/O, and test points. Only one device should be inserted at any time.
7. Test Points - Two sets of 64 test point headers are provided, with common connections. One set has
dual headers installed for easy attachment of external circuits or daughter boards. The other set allows
custom connection to the breadboard area.
8. 4 LEDs - The four LEDs are connected to DVCC only. TP6-TP9 can be connected to any device
outputs, or your own circuits, for visual debugging.
9. RS232 Port - A DB9 serial connector (P1) and on-board circuitry (U5) provide a turn-key RS232
interface. UART Software drivers are available on the CD.
10. RJ11 Connector - This connector (P3) is tied to the G4, G5, G6 device pins, and supports the
Microwire/PLUS™ interface for ISP, or any other external application.
11. KANDA ISP Connector - This 2x5 connector (P2) is for the Kanda COP8-ISP programming tool.
This tool supports both Parallel and Serial PC connections, a wide variety of clock frequencies, and
eliminates the need for the manual ISP reset operation.
12. COP8 Flash Emulator Header - This 2x7 header (J1) allows connection of a realtime, full-featured
emulator for full, interactive debugging. When not used, the jumpers must be installed.
NOTES
1) <5v Operation with COP8S and COP8C Flash devices.
Non-Brownout (COP8SDx, COP8CDx) and Low-Brownout (COP8SBx, COP8CBx) Flash devices
operate down to 2.7v, but not at full speed. If the board is set up for less than 4.5v operation, the 10MHz
crystal must be replaced with a 3.33MHz crystal. This meets the datasheet specs, and insures the correct
flash timing parameters. (The COP8 can actually run faster at low voltages, and will erase and program the
flash, but the effects on the flash memory over time are unknown.) Hi-Brownout versions (COP8SCx,
COP8CCx), and COP8A flash devices are 5v only devices.
2) Low voltage RS232 operation.
