Product specifications
ERF1002
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 SIG certified Bluetooth Low Energy SoC integrates a Bluetooth 5.0 compliant radio with an ARM® Cortex® M0 application processor, 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 full system power and has been designed to extend battery life for the Internet-of-Things (IoT) applications. Support for low duty cycle operation allows systems to run for significantly longer time periods without battery replacement.
