Description

The EM78P813 is an 8-bit CID (Call Identification) RISC type microprocessor with low power, high speed CMOS technology. There are 64Kx13 bits and 256Kx8 bits Electrical One Time Programmable Read Only Memory (OTP-ROM) within it. It provides security bits and some One time programmable Option bits to protect the OTP memory code from any external access as well as to meet user's options.

Integrated onto a single chip are on chip watchdog (WDT), programmable real time clock/counter, external/internal interrupt, power down mode, LCD driver, FSK decoder, Call waiting decoder, Energy Detector (DED) , DTMF receiver, Programming Tone generator, build-in KEY TONE clock generation, Comparator and tri-state I/O. The EM78P813 provides a single chip solution to design a CID of calling message display.
