Product Summary
The PCD5003H 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 PCD5003H is fast I2C-bus compatible(maximum 400 kbits/s). The applications of the PCD5003H are Display pagers, basic alert-only pagers, Information services, Personal organizers, Telepoint, Telemetry/data transmission.
