IoT wireless chip adds scalable memory and 802.15.4 support for Thread and Matter
Atmosic Technologies has added Matter and Thread support to its low power Bluetooth LE wireless chip alongside a scalable memory architecture.
The Atmosic ATM34/e system-on-chip (SoC) series supports latest Bluetooth LE 5.4 standard as well as 802.15.4 for Matter and Thread for low power end IoT devices such as sensors and switches. The chip is pin compatible with the previous Bluetooth LE devices to provide a drop in replacement with Matter IoT interoperability.
The new scalable memory architecture allows developers to use a memory footprint that meets the needs of their protocol, application, and cost targets.
The ATM34/e series integrates a 64MHz ARM Cortex M33F controller core with TrustZone technology for robust security alongside a radio front end that consumes less than 1mA in receive mode and an energy-efficient transmitter with a programmable output power range of -20dBm to +10dBm. These significantly extend battery life in connected devices and can even enable some devices to operate battery-free.

“Interoperability in the smart home is critical, creating a growing demand for connected devices that support standards-based wireless protocols. Thread and Matter enable smart home and mobile platforms to seamlessly communicate with each other regardless of the device manufacturer,” said David Su, CEO of Atmosic.
“Atmosic’s multiprotocol ATM34/e is designed to maximize a device’s performance while minimizing energy consumption. This allows product manufacturers to bring sustainable products to market at a lower cost and meet the industry’s latest connectivity requirements.”
The ATM34/e series is currently available in two packages: a 5×5 40-pin QFN and a 7×7 56-pin QFN. Both packages are pin-to-pin compatible with Atmosic’s ATM33/e series Bluetooth SoCs for customers looking to add 802.15.4 support without redesigning their product.
Product samples for the ATM34/e will be available starting in Q1 2024.
