INTRODUCTION

This data sheet details the specific features of the:

PCD5090/xxx; DSP-ROM, with external ROM

PCA5097/xxx; DSP-ROM, with Field Electronically

Erasable Programmable Read Only Memory

(FEEPROM).

FEATURES

General

• The PCx509x is designed for GAP-compliant handsets

and simple base stations

• Embedded 80C51 microcontroller with twice the

performance of the classic architecture, up to

128 kbytes external memory or 64 kbytes FEEPROM

program memory and 3 kbytes of data memory on chip.

In addition there is 1 kbyte of on-chip data memory that

is shared with on-chip Burst Mode Logic (BML) and

DSP, the System Data RAM (SDR).

• 80C51 ports P0, P1, P2 and P3 available for interfacing

to display, keyboard, I2C-bus, interrupt sources and/or

external memory. External program memory is

addressable up to 128 kbytes (PCD5090/xxx and

PCA5097/xxx).

• Portable Part (PP) and Fixed Part (FP) modes

• TDMA frame (de)multiplexing; transmission or reception

can be programmed for any slot

• Ciphering, scrambling, CRC checking/generation,

protected B-fields

• Speech and data buffering space for six handsets

• Local call and B-field loop-back

• Two interrupt lines for BML and DSP to interrupt 80C51

• On-chip, three-channel time-multiplexed 8-bit

Analog-to-Digital Converter (ADC) for RSSI

measurement and battery voltage measurement. One

channel available for other purposes.

• On-chip 8-bit DAC for frequency adjustment of

13.824 MHz on-chip crystal oscillator

• Phase error measurement and phase error correction by

hardware

• Digital-to-Analog Converters (DACs) and ADCs for

dynamic earpiece and dynamic or electret microphone

• On-chip reference voltage

• On-chip supply for electret microphone

• Very low ohmic buzzer output

• Serial interface to external ADPCM CODEC (PCD5032)

• IOM-2interface (Siemens registered trademark)

• Serial interface to synthesizer for frequency

programming

• Programmable timing of radio-control signals

• Programmable polarity of radio-control signals

• Easy interfacing with radio circuits, operating at other

supply voltage

• Programmable GMSK pulse shaper

• On-chip comparator for use as bit-slicer

• Power-on reset

• Low supply voltage (2.7 to 5.5 V)

• SACMOS technology.

DSP software features

• ADPCM encoding and decoding complying with G.721

• Speech filters

• Programmable gain in speech paths

• Side tone and soft mute

• Ringer and tone (DTMF) generator

• Dial tone detection

• Echo cancellation

• Automatic gain control

• Telephone Answering Machine (TAM) switch

• Conference call (PCD5090/400)

• Hands-free operation (PCD5090/311).

For each DSP software version a separate manual is

available, in which detailed information is provided on how

parameters must be set.
