GENERAL DESCRIPTION
The TM89P52M is a One Time PROM embedded high-performance 4-bit 
microcomputer with LCD driver. It contains all the necessary functions, 
such as 4-bit parallel processing ALU, ROM, RAM, I/O ports, timer, clock 
generator, dual clock operation, Resistance to Frequency Converter (RFC),
EL panel driver, LCD driver, look-up table, watchdog timer and key matrix 
scanning circuitry in a signal chip.
