DESCRIPTION

The SM5K3/5K4/5K5 are CMOS 4-bit single-chip microcomputers incorporating 4-bit parallel processing function, ROM, RAM, 10-bit A/D converter and timer/counters.

It provides three kinds of interrupts and 4 levels subroutine stack. Being fabricated through CMOS process, the chip requires less power and available in a small package : best suitable for Low power controlling, compact equipment like a precision charger.
