CC1021 Single Chip Low Power RF Transceiver for Narrowband Systems
Applications
• Low power UHF wireless data
transmitters and receivers with channel
spacings of 50 kHz or higher
• 433, 868 and 915 MHz ISM/SRD band
systems
• AMR ñ Automatic Meter Reading
Product Description
CC1021 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 433, 868 and 915 MHz, but can
easily be programmed for multi-channel
operation at other frequencies in the 402 -
470 and 804 - 940 MHz range.
The CC1021 is especially suited for
narrowband systems with channel
spacings of 50 kHz and higher complying
with EN 300 220 and FCC CFR47 part 15.
The CC1021 main operating parameters
can be programmed via a serial bus, thus
making CC1021 a very flexible and easy to
use transceiver.
