Objective specification

Low cost; low power DECT baseband

controllers (ABC-PRO)

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).
