ERF1002, Extreme low power Bluetooth 5.0 Module
The ERF1002 module is an extreme low-power Bluetooth® 5 system-on-a-chip (SoC) solution. This innovative module design is based on the extremely low power Atmosic M2 Series Bluetooth wireless platform. The ERF1002 design incorporates several innovative features that have a dramatic impact on extending the battery life of edge-of-network connected IoT products.
This Bluetooth Low Energy SoC integrates a Bluetooth 5.0 compliant radio with an ARM® Cortex® M0 application processor, 128 KB, 512 KB or 1MB embedded Flash, 128 KB Random Access Memory (RAM), 256 KB Read-Only Memory (ROM), 4 KB One-Time-Programmable (OTP) memory, and state-of-the-art power management.
The extremely low power ATM2 series SoC with 900uA active Rx and 2.4 mA active Tx has been designed to extend battery life for Internet-of-Things (IoT) applications. Support for low duty cycle operation allows systems to run for significantly longer time periods without battery replacement.
