II. General Description
This 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, Energy Detector (DED), Tone generator,
ASPCM voice synthesizer (decoder), voice ROM, Current DAC and tri-state I/O. It provides a single chip solution
to design a CID of calling message display.
III. Application
Caller ID adjunct box or phone units for FSK/DTMF CID dual system development.
