描述 Description

EM73P968 is an advanced single chip CMOS 4-bit one time programming (OTP) micro-controller. It contains16K-byte ROM, 2.5K nibbles RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, two 12-bit timer/counters for the kernel function. EM73P968 also contains 6 interrupt sources, 1 input port, 8 bidirection ports, MaxLCD display (52x5), built-in watch-dog-timer and high speed Timer/Counter.
An analog to digital (A/D) converter having 8-bit multipler analog input and 8-bit resolution. Serial peripheral interface (SPI).
EM73P968 has plentiful operating modes (SLOW, IDLE, STOP) intended to reduce the power consumption.
