The TMP90C051F is a high-speed 8-bit CMOS microproces-
sor with advanced functions and was developed for applica-
tion in various types of device control.
The TMP90C051F is a single-chip, 8-bit CMOS micropro-
cessor that integrates peripheral functions such as DMA, DRAM
controller, serial interface, timer/event counter and real time
clock with an 8-bit CPU (TLCS90) core. Memory area can also
be extended up to 8M bytes depending on the MMU.
The TMP90C051F features are as follows.
