描述 Description

The EM78P862A is an 8-bit RISC type microprocessor with low power, high speed CMOS technology. Integrated onto a 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 EM78P862A provides a single chip solution to design a DATA-BANK of message display.
