1. OUTLINE AND CHARACTERISTICS
TMP90C840
The TMP90C840 is a high-speed advanced 8-bit micro controller applicable
to a variety of equipment.
With its .8-bit CPU, ROM, RAM, A/D converter, multi-function timer/event
counter and general-purpose serial interface integrated into a single CMOS
chip, the TMP90C840 allows the expansion of external memories for programs
(up to 56K bytes) and data (1M bytes).
The characteristics of the TMP90C840 include:
