3 GENERAL DESCRIPTION

The PCD5003 is a very low power POCSAG decoder and

pager controller. It supports data rates of 512, 1200 and

2400 bits/s using a single 76.8 kHz crystal. On-chip

EEPROM is programmable using a minimum supply

voltage of 2.0 V, allowing ‘over-the-air’ programming.

The PCD5003 is fast I2C-bus compatible

(maximum 400 kbits/s).
