PCD5002 General Description
PCD5002 Features
` Wide operating supply voltage range: 1.5 to 6.0 V
` EEPROM programming requires only 2.0 V supply
` Low operating current: 50 mA typ. (ON), 25 mA typ. (OFF)
` Temperature range -25 to +70 °C
` "CCIR radio paging Code No. 1" (POCSAG) compatible
` Supports Advanced Pager Operator's Code Phase 1 (APOC-1) for extended battery economy
` 512, 1200 and 2400 bits/s data rates using 76.8 kHz crystal
` Built-in data filter (16-times oversampling) and bit clock recovery
` Advanced ACCESSâ synchronization algorithm
` 2-bit random and (optional) 4-bit burst error correction
` Up to 6 user addresses (RICs), each with 4 functions/alert cadences
` Up to 6 user address frames, independently programmable
` Standard POCSAG sync word, plus up to 4 user programmable sync words
` Continuous data decoding upon reception of user programmable sync word (optional)
` Received data inversion (optional)
` Call alert via beeper, vibrator or LED
` 2-level acoustic alert using single external transistor
` Alert control: automatic (POCSAG type), via cadence register or alert input pin
` Separate power control of receiver and RF oscillator for battery economy
` Synthesizer set-up and control interface (3-line serial)
` On-chip EEPROM for storage of user addresses (RICs), pager configuration and synthesizer data
` On-chip SRAM buffer for message data
` Slave I2C-bus interface to microcontroller for transfer of message data, status/control and EEPROM programming (data transfer at up to 100 kbits/s)
