Digital telephone answering machine chip
Product specification
PCD6003
• API providing flash memory management functions
such as speech, telephone or CID data storage
• Pin and software compatible with the PCD6002
OTP-device (see Application note for restrictions).
2 APPLICATION SUMMARY
The PCD6003 can be used in various applications, some
of which are listed below. Refer to Chapter 18 for the
corresponding outline application diagrams.
• Stand-alone digital answering machine; with handsfree
• Feature phone with integrated digital answering
machine and full-duplex handsfree with excellent BNS
• Dual-line digital answering machines
• Multi-party conference call applications
• Multi-line answering machine applications
• Analog cordless applications such as CT0/1 base
stations; with handsfree and MSK modem function for
RF digital data transmission
• Portable voice memo recorders
• Automotive applications - car status announcements for
example
• Low-cost desktop video conferencing
• IOM master/slave interface to connect directly to digital
systems like ISDN and DECT.

3 GENERAL DESCRIPTION
The PCD6003 integrates all the digital and analog speech
management and processing functions required for a
feature-phone with integrated digital answering machine,
or a stand-alone digital answering machine into a single
low-cost chip.
Key hardware features which give the chip distinct
advantages in performance and application over
competitive solutions include:
• Patented high quality 16.0 kbits/s P2CM music
transparent encoding and decoding with excellent
Background Noise Subtraction algorithm
• The flexibility to change the MMI
• An easy-to-program standard 80C51 microcontroller
with 32-kbyte internal ROM memory
• High 80C51 microprocessor power for system controller
functions of CT0/CT1 system control functions
• Up to 38 general purpose I/O lines for peripheral control
• I2C-bus interface
• Flexible flash memory control to interface to several
types of serial and parallel flash memory
• Two integrated 16-bit bitstream audio CODECs for true
full-duplex handsfree operation or dual-line stand-alone
answering machine operation
• Internal Digital Speech Processor (DSP) for excellent
‘HARMONY’ sinusoidal speech compression,
decompression and variable playback speed
• Embedded DTMF detection, call progress detection,
voice operated recording (VOX)
• High quality caller ID FSK demodulation and Caller
Alerting Signal (CAS) detection for CID level 2
• Two channel telephone line input for caller ID FSK and
audio interfacing.
Philips provides a sophisticated API running on the
internal 80C51, allowing product developers to design
their MMIs quickly to suit particular applications. The API
takes care of all flash memory and DSP management
tasks and can be enhanced on request.
For the pre-recorded voice prompts, the Philips
International Language Library (PILL) tools are available
for a standard multimedia PC platform under
Windows 95/NT. These tools provide a way to compile a
range of multi-lingual voice prompts for efficient storage in
the speech (flash) memory. The PILL tools support various
languages and their grammar adaptations.
