SINGLE-CHIP 16-BIT CMOS MICROCOMPUTER
DESCRIPTION
These are single-chip microcomputers designed with high-perfor-
mance CMOS silicon gate technology, including the internal flash
memory. These microcomputers support the 7900 Series instruction
set, which are enhanced and expanded instruction set and are up-
per-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. Therefore, these mi-
crocomputers are suitable for office, business, and industrial equip-
ment controller that require high-speed 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.
