GENERAL DESCRIPTION

The PCD5091 is designed for GAP-compliant handsets with speaker-phone option. It has an embedded 80C51 microcontroller with twice the performance of the classic architecture, 64 kbytes of PROM 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).

FEATURES

? 80C51 ports P0, P1, P2 and P3 available for interfacing to display, keyboard, I2C-bus, interrupt sources and/or external memory. Integrated 64 kbyte ROM, 3 kbytes of data memory and 1 kbyte SDR-RAM. External program memory is addressable up to 128 kbytes

? +2.7 to +5 V port (P0 to P3) interface

? TDMA frame (de)multiplexing. Transmission or reception can be programmed for any slot

? Ciphering, scrambling, CRC checking/generation and 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, one for battery voltage measurement and one channel available for other purposes

? On-chip 8-bit Digital-to-Analog Converter (DAC) for electronic potentiometer function

? Phase error measurement and phase error correction by hardware

? 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) or 8 kHz u-law samples

? Speech switch for Digital Telephone Answering Machine (DTAM) connected to SPI interface

? IOM-2 interface (Siemens registered trademark)

? Serial interface to synthesizer for frequency programming

? Programmable polarity and timing of radio-control signals

? GMSK pulse shaper

? Easy interfacing with radio circuits, operating at other supply voltage (RF supply pin with level shifter for RF signals)

? On-chip comparator for use as data-slicer

? Low power oscillator with integrated frequency adjustment

? QFP100 and LQFP100 packages

? Power-on-reset

? Programmable power-down modes

? Low supply voltage (2.7 to 3.6 V)

? CMOS technology.
