TM8762
GENERAL DESCRIPTION
The TM8762 is an embedded high-performance 4-bit microcomputer with LCD/LED 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.
BLOCK DIAGRAM
FEATURE
1.Low power dissipation.
2.Powerful instruction set (143 instructions).
