1. Things to Check When Unpacking

The M38C89T-ADF package consists of the following products. When unpacking your package,
check to see that all of these components are included.

* If you find any item missing or faulty, or any suggestion, contact your local distributor.

The M38C89T-ADF is a temporary target board used to develop software with a PC4701 emulator
system. It supplies to the M38C89RLFS MCU the minimum required signals needed to operate the
emulator MCU, including power supply voltage, clock signals and reset signals. Use it when the
target system is not ready. A block diagram of the M38C89T-ADF is shown in Figure 2.1.

IC1 has a pattern for mounting a socket for an M38C89MF-xxxFP/M38C89EFFP. This makes it
possible for this board to debug programs using an emulator MCU in IC2 or execute programs using
an M38C89MF-xxxFP/M38C89EFFP. A socket for M38C89MF-xxxFP/M38C89EFFP and parts
for an LCD bias circuitry are not mounted. Mount them as necessary.

Expansion boards can be installed in the through-holes of connectors J2, J3 and J4. Spacing between
connectors is given in Figure 2.1. Keep connector location in mind when making expansion boards.
Use 2.54-mm-pitch connectors. For pin array, see Table 8.1.
