EM73963A - 4-BIT MICRO-CONTROLLER

General Description

EM73963A is an advanced single chip CMOS 4-bit micro-controller.

It contains 16K-byte ROM, 372-nibble RAM, 4-bit ALU, 13-level subroutine nesting, 22-stage time base, two 12-bit timer/counters for the kernel function.

Key Features

  • • Operation voltage • Clock source : 2.4V to 5.5V. : Dual clock system. Low-frequency oscillator is Crystal or RC oscillator (32KHz, connect a external resistor) by mask option and high-frequency oscillator is RC oscillator (connect a external resistor and a capacitor). External clock and internal clock is available by mask option. Oscillation frequency : 480K, 1M, 2M and 4M Hz are both available for high frequency clock by mask option. Instruction set : 107 powerful instructions. Instruction cy.
