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.
