The PCD5003A 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 PCD5003A is fast I
(maximum 400 kbits/s).
