Product Description

CC400 is a single-chip high performance,

half-duplex, FSK, UHF transceiver

designed for low power and low-voltage

wireless applications. The circuit is mainly

intended for the ISM (Industrial, Scientific

and Medical) frequency bands at 315, 418

and 433 MHz, but can easily be

programmed for operation at other

frequency bands in the 300 - 500 MHz

range.

The main operating parameters of CC400

can be programmed via a serial interface,

thus making CC400 a very flexible and

easy to use component. In a typical

system CC400 will be used together with a

microcontroller and a few external passive

components.
