SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER FLASH MEMORY VERSION
MITSUBISHI MICROCOMPUTERS
DESCRIPTION
These are single-chip microcomputers designed with high-perfor-
mance CMOS silicon gate technology, including the internal flash
memory. These are housed in 100-pin plastic molded QFP. These
microcomputers support the 7900 Series instruction set, which are
enhanced and expanded instruction set and are upper-compatible
with the 7700/7751 Series instruction set.
The CPU of these microcomputers is a 16-bit parallel processor that
can also be switched to perform 8-bit parallel processing. Also, the
bus interface unit of these microcomputers enhances the memory
access efficiency to execute instructions fast. These microcomputers
include the 4-channel DMA controller and the DRAM controller.
Therefore, these microcomputers are suitable for office, business,
and industrial equipment controller that require fast processing of
large data.
For the internal flash memory, single-power-supply programming
and erasure, using a PROM programmer or the control by the cen-
tral processing unit (CPU), is supported. Also, each of these micro-
computers has the memory area dedicated for storing a certain
software which controls programming and erasure (reprogramming
control software). Therefore, on these microcomputers, the program
can easily be changed even after they are mounted on the board.
