1 General Description
The EM78869 is an 8-bit RISC type microprocessor with low power, high speed CMOS
technology. Integrated into the single chip are on chip watchdog (WDT), RAM, ROM,
programmable real-time clock/counter, internal interrupt, power-down mode, LCD driver, and
tri-state I/O. The EM78869 provides a single chip solution for designing DATA-BANK of
message display.
The EM78869 is the cost-down version of its predecessor, the EM78862/B. Comparison
between the two series is as follows:
