Overview
The CC1020RSST is a single-chip UHF RF transceiver designed by Texas Instruments for low-power and low-voltage wireless applications. It is primarily intended for use in the Industrial, Scientific, and Medical (ISM) and Short Range Device (SRD) frequency bands, covering frequencies from 402 MHz to 470 MHz and 804 MHz to 930 MHz. The device is highly flexible and can be programmed for multichannel operation, making it suitable for narrow-band systems with channel spacing of 12.5 or 25 kHz, complying with standards such as ARIB STD-T67 and EN 300 220.
