Phone 8-Bit MCU with DTMF Receiver & CPT

Rev. 1.00

March 12, 2010

General Description

The phone MCU is a 8-bit high performance, RISC ar-

chitecture microcontroller devices specially designed

for telephone applications. Devices flexibility are en-

hanced with their internal special features such as

power-down and wake-up functions, DTMF generator,

DTMF receiver, CPT detector, PFD driver, SPI and I

2C

interface, audio DAC output, etc. These features com-

bine to ensure applications require a minimum of exter-

nal 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 DTMF mode Caller ID

phone, Home Security products, deluxe feature

phones, cordless phones, fax and answering machines,

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.
