APPLICATION SUMMARY
The PCD6001 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
Dual-line digital answering machines
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.
2.1
Metalink emulation
Metalink emulation is supported with the standard
package.

GENERAL DESCRIPTION
The PCD6001 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:
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

C-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.
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.
