ATM33

The ATM3330e/ATM3330 are part of a family of extreme low-power Bluetooth® 5.3 system-on-chip (SoC) solutions.

This Bluetooth Low Energy SoC integrates a Bluetooth 5.3 compliant radio with ARM® Cortex® M33F application processor, 128 KB Random Access Memory (RAM), 64 KB Read-Only Memory (ROM), 512 KB nonvolatile memory (NVM), with ARM® TrustZone® enabled security features, and state-of-the-art power management to enable maximum lifetime in battery-operated devices.

The extremely low power ATM3330e/ATM3330 SoC, with a 0.7 mA radio receiver and a 2.1 mA radio transmitter power consumption, is designed to extend battery life for the Internet-of-Things (IoT) markets

Support for low duty cycle operation allows systems to run for significantly longer periods without battery replacement. In addition, this series of SoCs from Atmosic supports operation from energy harvesting sources, including RF, photovoltaic, TEG (Thermoelectric generator), and motion. Innovative wake-up mechanisms are supported to provide options for further power consumption reduction.
