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.)
