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.
Remote control systems
Home security and automation
Low power telemetry
AMR – Automatic Meter Reading
Environmental control
CC400 is based on Chipcon’s SmartRF®
technology.
