PCD509x2

The PCD509x2 family is designed for low power GAP compatible DECT handset (PP) and base station (FP) applications. The circuit of PCD509x2 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 of PCD509x2 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 of PCD509x2 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 PCD509x2 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).
