EM78810
8-BIT MICRO-CONTROLLER FOR TELECOM PRODUCT
GENERAL DESCRIPTION
The EM78810 is an 8-bit CID (Call Identification) 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 , FSK decoder , DTMF generator
and tri-state I/O . The EM78810 provides a single chip solution to design a CID of calling message_display .
