EM78910A General Description
The EM78910/910A is an 8-bit CID (Call Identification) RISC type microprocessor with low power, high speed CMOS technology. This integrated single chip has on_chip watchdog (WDT), RAM, ROM, programmable real time clock/counter, internal interrupt, power down mode, FSK decoder, Call waiting decoder, SDT (Stuttered dial tone) decoder, DTMF generator, MEI (Multiple Extension Internetworking) function, RTF (Request To Flash) function and tri-state I/O. The EM78910/910A provides a single chip solution to design a CID of calling message_display.
