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.
