Objective specification
PCD509x2/zuu/v family
2 GENERAL DESCRIPTION
The PCD509x2 family is designed for low power GAP
compatible DECT handset (PP) and base station (FP)
applications. The circuit includes the audio interface, the
DSP, the microcontroller and the Burst Mode Logic, and
contains all functionality to convert speech and data
signals from/to the analog side (microphone and earpiece
or line interface circuit) to/from the radio side
(1.152 Mbits/s data).
This circuit is a member of the ABC family, where A stands
for ‘ADPCM codec’, B for ‘Burst Mode Logic’ and C for
‘microController’. The name ABC-PRO stands for
PROfessional ABC.
The PCD509x2/zuu/v contains on-chip ROM for the
embedded DSP code and on-chip ROM for the embedded
microcontroller code. It is these ROM codes that
differentiate between various chip derivatives. For each
DSP code a separate DSP user manual is published.
Please contact Philips Semiconductors for more
information.
This family specification contains the hardware description
that is independent of the used ROM codes.
The numerical digit ‘x’ in PCD509x2 determines the
intended application area (e.g. PCD50912 for use in
handsets or PCD50922 for use in simple base stations,
etc.). The last numerical digit ‘2’ is used to denote
hardware derivatives. The extension digits ‘z’ (A to Z) and
‘uu’ (00 to 99) denote the DSP and the microcontroller
software version, respectively. The extension ‘v’ denotes
the hardware version updates of the circuit.
Although the microcontroller ROM code is present on-chip,
an external program memory for the microcontroller code
can be used. This is not the case for the DSP ROM code
which is fixed by the chip version.
Throughout this family specification the term PCD509x2 is
used to cover all sub types and versions. If any specific
feature or parameter is connected to a certain sub type or
version this will be specifically written. Until otherwise
stated this family specification is valid for hardware
version 1 (v = 1).
