ATM34
The ATM34 and ATM34e are members of the new ATM34/e series that supports both Bluetooth LE and/or 802.15.4 for highly robust command/control or home automation type protocols.
The SoC family integrates the radio along with an ARM® Cortex® M33F application processor, up to 256 KB Random Access Memory (RAM), 64 KB Read-Only Memory (ROM), 512-2560 KB of nonvolatile memory (NVM).
The family also supports the ARM® TrustZone® enabled security features, and state-of-the-art power management to enable maximum lifetime in battery-operated devices and integrated energy harvesting capabilities
The extremely low power ATM34 and ATM34e series SoCs, with a 0.95 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.
