K0RE81 Evaluation Platform for µPD78F9882
1. INTRODUCTION
To facilitate design with an NEC Electronics flash microcontroller, a specific device, along
with appropriate crystals and reset circuitry is provided on a printed circuit board. All of the
package pins are brought out to standard 0.1-inch headers that surround the microcontroller
package on all four sides.
The K0RE81 board employs the µPD78F9882 flash microcontroller, which is identical to the
µPD789881 mask ROM version, except that it does not exhibit the same ultra-low-power
performance. A design therefore would be implemented in the K0RE81 board via the
µPD78F9882, and the code and operation thoroughly debugged before committing to mask
ROM release.

2. CONNECTING TO THE K232 SERIAL ADAPTER
There are two ways to connect to the K232. The first is via the J2 10-pin stackable header.
Figure 2 shows the board’s orientation for stacking.

The second is with an extension ribbon cable supplied with the K232 that plugs onto the P1
10-pin header on the circuit side of the K232. The other side plugs into the flash programmer
header on the K0RE81. These connections use keyed headers and can only be plugged in
one way. See Figure 3.

3. K232 JUMPER SETTINGS FOR THE K0RE81
1. Connect jumper JP1 if you want the K0RE81 to derive power from the K232 adapter.
2. Set jumper JP2 for 3.3-volt operation.
3. Set JP3 jumper on TX (pins 1–2)
4. Set JP4 jumper on RX (pins 2–3.
5. JP5 requires no jumper.
4. PRE-FLASHED FIRMWARE
The K0RE81 was flashed in manufacturing with the K0SM9882 mini-monitor program for
testing and diagnostics. The K232 will work with the K0RE81 right out of the box. Check the
K232 User’s Manual for communication port settings.
