CC1021
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, 915, and 960 MHz ISM/SRD
band systems
• Wireless alarm and security systems
• Home automation
• Low power telemetry
• Automotive (RKE/TPMS)
• AMR – 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 - 960 MHz range.
In a typical system CC1021 will be used
together with a microcontroller and a few
external passive components.
The CC1021 is especially suited for
narrowband systems with channel spacing
of 50 kHz and higher complying with EN
300 220, FCC CFR47 part 15, and ARIB
STD-T96.
The CC1021 main operating parameters
can be programmed via a serial bus, thus
making CC1021 a very flexible and easy to
use transceiver.
