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.
