The EM78P468N is an 8-bit RISC type microprocessor with high speed CMOS technology and low

power consumption. Integrated onto a single chip are on chip watchdog (WDT), Data RAM, ROM,

programmable real time clock counter, internal/external interrupt, power down mode, LCD driver

IROUT function, and tri-state I/O. It provides a PROTECTION bit to protect against intrusion of user’s

code in the OTP memory and a 10-OPTION bit to accommodate user’s requirements.
