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 I
2
C-bus compatible
(maximum 400 kbits/s).
