Atmosic Technologies, a key player in ultra-low-power wireless platforms for the Internet of Things (IoT), has announced the release of the ATM34/e high-performance system-on-chip (SoC) series. This latest addition to Atmosic’s lineup features multiprotocol support, building on the success of the Bluetooth LE-supported ATM3 and ATM33/e SoCs. The ATM34/e series introduces IEEE 802.15.4 based protocols like Thread and Matter, along with enhanced Bluetooth LE support aligned with the latest 5.4 standard revision.
Tailored for ultra-low-power IoT devices such as sensors and switches, the ATM34/e series distinguishes itself by typically consuming 50% less active energy than competing solutions. Notable features include a best-in-class radio that operates with less than 1mA in receive mode, and an energy-efficient transmitter offering a programmable output power range of -20dBm to +10dBm. These innovations contribute significantly to extending the battery life of connected devices and, in some cases, enabling battery-free operation.
David Su, CEO of Atmosic, highlighted the significance of interoperability in the smart home, stating, “Thread and Matter enable smart home and mobile platforms to seamlessly communicate with each other regardless of the device manufacturer. Atmosic’s multiprotocol ATM34/e is designed to maximize a device’s performance while minimizing energy consumption, allowing product manufacturers to bring sustainable products to market at a lower cost and meet the industry’s latest connectivity requirements.”
The ATM34/e series introduces a scalable memory architecture, allowing developers to optimize the memory footprint to align with protocol, application, and cost targets. With a 64MHz Arm Cortex M33F processor for power and performance optimization, the SoCs also support Arm’s TrustZone technology, enhancing security.
Continuing Atmosic’s commitment to energy efficiency, the ATM34/e series integrates energy harvesting technology, efficiently capturing, using, and storing energy from various sources such as RF, heat, light, and motion. This capability, combined with a wide harvesting input range and support for various storage devices, enables smart sensors and low-power automation applications to operate unattended for extended periods.
The ATM34/e series is currently available in two packages: a 5×5 40-pin QFN and a 7×7 56-pin QFN. Notably, both packages are pin-to-pin compatible with Atmosic’s ATM33/e series Bluetooth SoCs, providing a seamless integration option for customers seeking to add 802.15.4 support without the need for a redesign. Samples for the ATM34/e series are expected to be available starting in Q1 2024.
