PCD5091; DECT baseband controller
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.
DSP software features
- ADPCM encoding and decoding complying with G.721
- Volume control
- Speech filters
- Programmable gain in speech paths
- Side tone and soft mute
- Two tone (DTMF) generators
- Automatic gain control
- Hands-free operation
For each DSP software version a separate manual is
available in which detailed information is provided on how
parameters must be set. For further information please
