SPSGRF Sub-GHz (868 or 915 MHz) low power programmable RF transceiver modules Datasheet - production data Certification: CE (SPSGRF-868) FCC (SPSGRF-915) IC (SPSGRF-915) Applications AMR (automatic meter reading) Home and building automation WSN (wireless sensor network) Industrial monitoring and control Wireless fire and security alarm systems Point-to-point wireless link Features Description Programmable radio features Based on Sub-1GHz SPIRIT1 transceiver The SPSGRF-868 and SPSGRF-915 are easy-to- and integrated Balun (BALF-SPI-01D3) use, low power sub-GHz modules based on the Modulation schemes: 2-FSK, GFSK, MSK, SPIRIT1 RF transceiver, operating respectively in GMSK, OOk, ASK the 868 MHz SRD and 915 MHz ISM bands. Air data rate from 1 to 500 kbps The modules provide a complete RF platform in a On-board antenna tiny form factor. Operating temperature range from -40 C The SPSGRF series enables wireless to 85 C connectivity in electronic devices, requiring no RF RF features experience or expertise for integration into the Receiver sensitivity: -118 dBm final product. As an FCC, IC, and CE certified solution, the SPSGRF series optimizes the time- Programmable RF output power up to to-market of end applications. The SPSGRF-915 +11.6 dBm is an FCC certified module (FCC ID: Host interface S9NSPSGRF) and IC certified (IC 8976C- SPI SPSGRF), while the SPSGRF-868 is certified CE. General I/O The modules are designed for maximum Up to 32 programmable I/O functions on 4 performance in minimal space and include 4 GPIO programmable module pins programmable I/O pins and SPI serial interfaces.
