Description

EM73362 is an advanced single chip CMOS 4-bit micro-controller. It contains 3K-byte ROM, 52-nibble RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, one 12-bit timer for the kernal function and one high speed counter. EM73362 also contains 5 interrupt sources, 1 input port, 4 bidirection ports, built-in watch- dog-timer and LCD driver (27x3 to 15x3).

Except low-power consumption and high speed, EM73362 has the STOP mode and IDLE mode operation for power saving function.
