(Controllers With 10-Bit A/D Converter)
SM5K5
DESCRIPTION
The SM5K3/5K4/5K5 are CMOS 4-bit single-chip
microcomputers incorporating 4-bit parallel pro-
cessing 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.
