DESCRIPTION

The 4501 Group is a 4-bit single-chip microcomputer designed with

CMOS technology. Its CPU is that of the 4500 series using a

simple, high-speed instruction set. The computer is equipped with

two 8-bit timers (each timer has a reload register), interrupts, and

10-bit A/D converter.

The various microcomputers in the 4501 Group include variations

of the built-in memory size as shown in the table below.

FEATURES

qMinimum instruction execution time ................................ 0.68 µs

(at 4.4 MHz oscillation frequency, in high-speed mode)

qSupply voltage ............................................................. 2.7 to 5.5 V
