16-BIT CMOS MICROCOMPUTER

DESCRIPTION

These are single-chip 16-bit microcomputers designed with high-per-

formance CMOS silicon gate technology, including the internal flash

memory and being packaged in 42-pin plastic molded SSOP or

shrink plastic molded DIP. 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. Therefore, these mi-

crocomputers are suitable for office, business, and industrial equip-

ment controller that require high-speed processing of large data.

Also, they are suitable for motor-control equipment since each of

them includes the motor control circuit.

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.
