Embedded World: Cortex-M33 Wireless MCUs for Bluetooth LE and Matter

SiLabs EFM32PG26 block

Silicon Labs has announced an Arm Cortex-M33 based family of secured wireless microcontrollers covering Matter, OpenThread, Zigbee and Bluetooth LE. Called xG26, it consists of MG26 devices for Matter, OpenThread and Zigbee, BG26 devices for Bluetooth LE and Bluetooth Mesh, and PG26 devices for the same processing power without wireless transceivers. “As users from consumer to industrial sectors extract more ...

Neural processor in Bluetooth and Matter wireless MCU

ALIF Balletto neural processor with bluetooth

Alif Semiconductor has put an Arm Ethos-U55 neural processor alongside a Bluetooth Low Energy radio in a microcontroller for AI and machine learning workloads – all in a tine WLCSP package. It is called Balletto. “Balletto gives manufacturers the opportunity to implement AI/ML functions such as speech recognition, adaptive noise cancellation, vocal targeting and beam forming in true wireless stereo ...

NXP reveals MCX MCUs with Matter, Thread, Zigbee and Bluetooth LE

NXP MCX W72x wireless mcu block

NXP has finally revealed the wireless versions of its MCX microcontrollers, first announced in mid-2022. “Featuring the industry’s first MCU with Bluetooth Channel Sounding, NXP’s MCX W series enables edge devices with secure multi-protocol wireless for Matter, Thread, Zigbee and Bluetooth Low Energy,” according to the company, which explained: “Bluetooth Channel Sounding standard improves the accuracy and security of distance ...

Wireless MCU modules cover Bluetooth LE 5.4, Thread and Matter

u-blox ALMA-B1 NORA-B2 bluetooth MCU

u-blox has announced four stamp-sized wireless MCU modules that can run user code and support Bluetooth LE 5.4, Thread, Matter and PSA Certified Level 3 security. ALMA-B10x versions are built around Nordic Semiconductor’s nRF54H20 wireless microcontrollers and have dual 320MHz Arm Cortex-M33 cores, dual 320MHz RISC-V cores, plus 2Mbyte of non-volatile memory and 1Mbyte ram. They also support NFC-A. NORA-B20x ...

ISSCC: Passive tag drinks Wi-Fi and spits Bluetooth

ISSCC24 paper 23.3 Zhejiang University Microaiot WiFi Bluetooth passive comms

Zhejiang University and Microaiot have created a passive crystal-less tag IC that both receives its instructions and is powered by Wi-Fi, and sends its responses over Bluetooth. They described the device at ISSCC in San Francisco this week. The tag has two antennas, with both used to extract power from the incident Wi-Fi field. One also receives the Wi-Fi (802.11b) ...

10 x 20mm Bluetooth 5.0 module has 250m range

Infineon CYW20822-P4TAI040 Bluetooth5 module

Infineon has introduced a ~10 x 20mm antenna-inclusive Bluetooth 5.0 (core spec) module that consumes 1.3mA receiving (-95dBm) and 3mA transmitting (0dBm). Called CYW20822-P4TAI040, it sleeps at 2μA when retaining 32kbyte of ram, or hibernates at 800nA – the latter rising to 950nA hibernating with the wake-up receiver enabled. At maximum transmit power (+4dBm) up to 250m of range can be ...

Wireless MCU for Bluetooth 5.3 LE in chip-scale package

ST STM32WB09 bluetooth MCU

ST has announced a wireless microcontroller with the Bluetooth 5.3 LE software, initially in a 5 x 5mm QFN, and scheduled to be available in a ~2.8 x 3mm chip-scale package. STM32WB09 (right) is built around a single Arm Cortex-M0+ core and will support 2Mbit/s data, long range (coded PHY), advertising extensions, angle-of-arrival, angle-of-departure, LE data packet length extension and ...
