Sub-GHz RF Transceiver ARM-M3 System-on-Chip with NFC
ER8131 Technical Highlights
ER813x is a family of high performance, high flexibility, low power Sub-GHz SoC for IOT applications. It benefits physical retail’s Electronic Shelf Label (ESL) market and extends to asset monitoring, manufacturing, and logistics. ER813x covers 490/868/915MHz ISM bands in sub-GHz frequency spectrum. In addition to supporting Sub-GHz band for long range connectivity, the product also comes with NFC, which is compliant with ISO/IEC 14443-3 standard (Type A), to provide contactless short-range connectivity to mobile device. ER813x realizes long range wireless data communication with high data rate up to 1Mbps. Its proprietary on‐chip power amplifier optimizes power consumption for applications that require output power up to +16dBm without external PA. ER813x has excellent Rx performance in sensitivity (-108dbm sensitivity @ 500Kbps/ 915Mhz/ GFSK) and is designed to provide multiple working power management modes with low RF receive current (Rx: 8mA@915MHz) as well as wake on RX (WOR) without MCU involvement to extend lifespan of battery operated devices such as electronic shelf labels, smart meters and disposable wireless sensors.
