CID Phone 8-Bit MCU with CPT

Rev. 1.00

March 3, 2010

General Description

The series of CID phone MCU are 8-bit high perfor-

mance, RISC architecture microcontroller devices spe-

cially designed for telephone applications. Devices

flexibility are enhanced with their internal special fea-

tures such as power-down and wake-up functions,

DTMF generator, DTMF receiver, FSK decoder, CPT

detector, PFD driver, SPI and I

2C interface, audio DAC

output, etc. These features combine to ensure applica-

tions require a minimum of external components and

therefore reduce overall product costs.

Having the advantages of low-power consumption,

high-performance, I/O flexibility as well as low-cost,

these devices have the versatility to suit a wide range of

application possibilities such as FSK & DTMF mode

Caller ID phone, Home Security products, deluxe fea-

ture phones, cordless phones, fax and answering ma-

chines, etc.

The call progress tone detector is for Auto-dialing sys-

tem use. Switched capacitors technology is imple-

mented into the chip to get good performance

characteristics of band pass filter in the range of 305Hz

to 640Hz call progress tone which is dual tone

multi-frequency signal. When it detected CPT signal

then it generates relative envelopes for external

microcontroller decision to finish different kinds of CPT

signal detection such as dial tone, busy tone, ring-back

tone and reorder tone.

The device will be ideally suited for phone products that

comply with versatile dialer specification requirements

for different areas or countries. The device is fully sup-

ported by the Holtek range of fully functional develop-

ment and programming tools, providing a means for fast

and efficient product development cycles.
