CC1000
Single Chip Very Low Power RF Transceiver
Applications
• Very low power UHF wireless data
transmitters and receivers
• 315 / 433 / 868 and 915 MHz ISM/SRD
band systems
• RKE – Two-way Remote Keyless Entry
Product Description
CC1000
is a true single-chip UHF trans-
ceiver designed for very low power and
very low voltage wireless applications. The
circuit is mainly intended for the ISM
(Industrial, Scientific and Medical) and
SRD (Short Range Device) frequency
bands at 315, 433, 868 and 915 MHz, but
can easily be programmed for operation at
other frequencies in the 300-1000 MHz
range.
The main operating parameters of
can be programmed via a serial bus, thus
CC1000
making
a very flexible and easy to
use transceiver.
In a typical system
CC1000
will be used together with a
microcontroller and a few external passive
components.
Features
