1 FEATURES
PCD5094
· Easy interfacing with radio circuits, operating at other supply voltage (RF supply pin with level shifter for RF signals) · QFP100 package · Power-on-reset · Low power oscillator with integrated frequency adjustment · Low supply voltage (2.7 to 3.6 V) · CMOS technology. 1.1 DSP software features
· 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 · +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 · On-chip comparator for use as data-slicer 3 ORDERING INFORMATION TYPE NUMBER PCD5094H
· ADPCM encoding and decoding complying with G.721 · u-law encoding and decoding complying with G.711 · Echo cancellation and network echo suppressor · Speech filters · Programmable gain in speech paths · Side tone and soft mute · Ringer and tone (DTMF) generator · Automatic gain control · Telephone Answering Machine (TAM) switch · TAM switch volume control · Conference between a/b line and two handsets. 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 contact Philips Semiconductors. 2 GENERAL DESCRIPTION
The PCD5094 is designed for GAP-compliant basestations offering conference call between the a/b line and two handsets and answering machine switch. 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).
PACKAGE NAME QFP100 DESCRIPTION plastic quad flat package; 100 leads (lead length 1.95 mm); body 14 × 20 × 2.8 mm VERSION SOT317-2
