DESCRIPTION

The 4250 Group is a 4-bit single-chip microcomputer designed

with CMOS technology. Its CPU is that of the 720 series using a

simple instruction set. The computer is equipped with one 8-bit

timer which has a reload register and the interrupt function.

The various microcomputers in the 4250 Group include variations

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

FEATURES

• Minimum instruction execution time ............................. 1.0

µs

(at 4.0 MHz system clock frequency, VDD=4.5 V to 5.5 V)

• Supply voltage

4.5 V to 5.5 V (at 4.0 MHz system clock frequency)

2.5 V to 5.5 V (at 1.0 MHz system clock frequency)

2.2 V to 5.5 V (at 1.0 MHz system clock frequency:

only for Mask ROM version)

• Timer

Timer 1 ................................ 8-bit timer with a reload register

• Interrupt ................................................................... 2 sources

• CR oscillation circuit (Capacitor and Resistor connected

externally)

• Logic operation instruction

• RAM back-up function

• Key-on wakeup function (ports G and S, INT pin)

APPLICATION

Electric household appliances, consumer electronics products

(mouse, etc.)
