EM73361A 4-BIT MICRO-CONTROLLER FOR LCD PRODUCT GENERAL DESCRIPTION EM73361A 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, two 12-bit timer/counters for the kernel function. EM73361A also contains 3 interrupt sources, 1 input port, 4 bidirection I/O ports, built-in watch-dog-timer counter, tone generator and LCD driver (27x3 to 13x3). Except low-power consumption and high speed, EM73361A also have a sleep mode operation for power saving.
