描述 Description

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.
