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 ...

Renesas is claiming “industry’s lowest overall power consumption for general purpose 32-bit MCUs” for its Arm Cortex-M23 based RA0 series. Consumption is 84.3μA/MHz and the company “offers a ‘software stand-by’ mode that reduces power consumption by a further 99% to 0.2 µA”, it said. Wake from this mode is in 4.6μs or less if the internal 32MHz oscillator is used. ...

Microchip has created an AVR microcontroller series with 12Mbit/s USB 2.0 and code protection. “As the next generation of Microchip 8-bit MCUs to integrate USB connectivity, the AVR DU family is designed to provide enhanced security features,” said the company. Protection comes from permanently disabling write capability within the programming and debug interface after initial programming, and handing over update ...

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 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 ...

Resasas has put its in-house developed 32bit RISC-V core into a few-pin general-purpose MCU series, following earlier RISC-V projects with Anders and SiFive. Announced last November, the core implementation can accommodate various standard RISC-V options, to which Renesas has added its own options including: a stack monitor register to protect against rogue software, a dynamic branch prediction unit improve the ...

Renesas has revamped the high-accuracy analogue front-end in its 32bit RX microcontrollers. Implemented in RX23E-B MCUs, the 24bit ΔΣ ADC, depending on configuration, can now convert at up to 125ksample/s – eight times faster than existing RX23E-A MCUs – or achieve a third of the noise – to 0.18µVrms at 1ksample/s. 24bit effective resolution can be achieved at 3.8sample/s. To go ...

Silicon Labs has built a family of 8bit microcontrollers around its 8051-based CIP-51 core, running at 50MHz. “The BB5 family supports voltage options from 1.8 to 5.5V, allowing them to last for years in the field on a coin-cell battery,” according to the company. “They also come in a variety of packing sizes, from 2 x 2mm for BB50, while ...

Alif Semiconductor’s 32bit ‘Ensemble’ AI-enabled MCUs are now available, according to the company. Built around various Arm cores with added security to protect stored intellectual property, they are intended to run AI algorithms locally in battery-powered devices. “There are many Edge ML applications that require 50 to 250Gop/s to become useful,” said Alif marketing v-p Mark Rootz. “Typical 32bit MCUs ...

Infineon has announced a family microcontrollers combining an Arm Cortex-M55 core (including ‘Helium’ DSP support), an Arm Ethos-U55 machine learning processor, and an Arm Cortex-M33 core, which has in-built security, paired with Infineon’s own ‘NNLite’ neural network accelerator. “Support for ‘always-on’ sensing and response makes the devices ideal for IoT and industrial segments such as smart home, security, wearables and ...
