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.
