General Description
HE89C21 General Description
HE89C21 is a member of 8-bit Micro-controller series developed by King Billion Electronics for telecom applications. This chip has 4-COM x 32-SEG LCD driver with built-in regulator to provide stable visual effect over the battery life, 16-bit general purpose I/O port, DTMF generator for the dialing tone generation. It is suitable for application in feature telephone products.
The instruction set of HE80000 are easy to learn and simple to use. Thirty-two instructions with four-typeaddressing mode are provided. Most of instructions take only 3 oscillator clocks to execute.
