EM78860
8-BIT MICRO-CONTROLLER
GENERAL DESCRIPTION
The EM78860 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 EM78860 provides a single
chip solution to design a message display .
FEATURES
