Product Overview

The SPSGRFC-915 from STMicroelectronics is a sub-1GHz programmable transceiver module. It is an easy to use transceiver certified module with many programmable features. The module provides a complete RF platform in a tiny form factor. The SPSGRFC RF module is CE, FCC and IC certified and integrates wireless connectivity in target electronic devices without requiring particular RF experience or expertise. This certified solution optimizes the time to market of final applications. The module is designed for maximum performance in a minimal space with 4 programmable I/O pins and an SPI serial interface. The SPSGRFC is pin to pin and firmware compatible with SPSGRF family applications. Typical application includes AMR (automatic meter reading), WSN (wireless sensor network), industrial monitoring and control, wireless fire and security alarm systems, point to point wireless link, 6LoWPAN MESH network and wireless M-Bus protocol stack.
