Description

EM73P461A is an advanced single chip CMOS 4-bit one-time programming (OTP) micro-controller. It contains 4K/8K-byte ROM, 244-nibble RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, two 12-bit timer/ counters for the kernel function. EM73P461A also contains 6 interrupt sources, 1 input port, 2 bidirection ports, LCD display (32x4), and one high speed timer/counter with melody output.

EM73P461A has plentiful operating modes (SLOW, IDLE, STOP) intended to reduce the power consumption.
