7477 General Description
The 7477/7478 group is the single-chip microcomputer designed with CMOS silicon gate technology.
The single-chip microcomputer is useful for business equipment and other consumer applications.
In addition to its simple instruction set, the ROM, RAM, and I/O addresses are placed on the same memory map to enable easy programming.
|
In addition, built-in PROM type microcomputers with built-in elec-trically writable PROM, and additional functions equivalent to the mask ROM version are also available.
7477/7478 group products are shown noted below.
The 7477 and the 7478 differ in the number of I/O ports, package outline, and clock generating circuit only.
