PCF5001 Datasheet PDF - Philips Electronics

GENERAL DESCRIPTION
The PCF5001 is a fully integrated low-power decoder and pager controller. It decodes the CCIR radio paging Code No.1 (POCSAG-Code) at 512 and 1200 bits/s data rates. The PCF5001 is fabricated in SACMOS technology to ensure low power consumption at low supply voltages.

FEATURES
• Wide operating supply voltage range (1.5 to 6.0 V)
• Extended temperature range: −40 to +85 °C (between
−40 to −10 °C, minimum supply voltage restricted to 1.8 V)
• Very low supply current (60 µA typ. with 76.8 kHz crystal)
• “CCIR radio paging Code No 1” (POCSAG) compatible
• Programmable call termination conditions
• 512 and 1200 bits/s data rates (2400 bits/s with some restrictions), see Section 7.4
• Improved ACCESS synchronization algorithm
• Supports 4 user addresses (RICs) in two independent frames
• Eight different alert cadences
• Directly drives magnetic or piezo ceramic beeper
• High level alert requires only a single external transistor
• Optional vibrator type alerting
• Silent call storage, up to eight different calls
• Repeat alarm facility
• Programmable duplicate call suppression
• Interfaces directly to UAA2050T, UAA2080 and UAA2082 digital paging receivers
• Programmable receiver power control for battery economy
• On-chip non-volatile EEPROM storage
• On-chip voltage converter with improved drive capability
• Serial microcontroller interface for display pager applications
• Optional visual indication of received call data using a modified RS232 format
• Level shifted microcontroller interface signals
• Alert on low battery
• Optional out-of-range indication.

APPLICATIONS
• Alert-only pagers, display pagers
• Telepoint
• Telemetry/data receivers.
