CID Phone 8-Bit MCU

Rev. 1.00

1

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, PFD

driver, SPI and I

2C interface, audio DAC output, etc.

These features combine to ensure applications require

a minimum of external components and therefore re-

duce 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 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.
