STMicroelectronics SPIRIT1 Low Data Rate, Low Power Sub-1GHZ Transceiver

STMicroelectronics SPIRIT1
Sub-1GHZ Transceiver

STMicroelectronics SPIRIT1 is a very low-power RF transceiver intended for RF wireless applications in the sub-1GHz band. SPIRIT1 is designed to operate both in the license-free ISM and SRD frequency bands at 169, 315, 433, 868, and 915MHz. This STMicroelectronics RF transceiver can also be programmed to operate at other additional frequencies in the 300-348MHz, 387-470MHz, and 779-956MHz bands. The air data rate is programmable from 1 to 500kbps. SPIRIT1 can be used in systems with channel spacing of 12.5/25kHz, complying with the EN 300 220 standard. This STMicroelectronics transceiver supports an embedded CSMA/CA engine. An AES 128-bit encryption co-processor is available for secure data transfer. The SPIRIT1 fully supports antenna diversity with an integrated antenna switching control algorithm.
