(1) CPU (IC101) TMP90CM38F (TMP90PM38F)
General
The TMP90CM38F is a high-performance 8-bit micro-controller
developed for use in control of various devices.
In the TMP90CM38F, the 8-bit CPU, ROM, RAM, the A/D convertor,
the multi-function timer, the event counter, the general-purpose serial
interface, the pattern generation, the stepping motor controller are
integrated into one chip. In addition, its memory can be extended up
to 31kbyte with the program memory and the data memory.
The TMP90PM38F includes the one-time PROM. By writing
programs into the one-time PROM, it performs the same operation
with the TMP90CM38F.
