STMicroelectronics has created a 40nm Bluetooth LE 5.3 wireless microcontroller family centred around a 100MHz Arm Cortex-M33 core – that’s the security-enabled version of the Cortex-M3, which has TrustZone virtualisation. Called STM32WBA52, the ICs are similar to the company’s earlier Cortex-M4-based STM32WB wireless microcontrollers, and have a +10dBm 2Mbit/s 2.4GHz transceiver (10.6mA at 0dBm TX, 7.4mA Rx) that can support ...

STMicroelectronics has introduced a 250MHz Arm Cortex-M33 microcontroller with the company’s own security hardware and software trusted execution environment (TEE) on top of Arm’s TrustZone. The part is the STM32H573 (or 563, ST has said both, watch this space), and the internal security system has been dubbed ‘STM32Trust TEE security manager’ (right). “STM32H5 is the first MCU series to come ...

At this week’s RISC-V Summit in San Jose, California, Balajii Baktha, founder and CEO of Ventana Micro Systems, used his keynote to introduce the Veyron V1 family of RISC-V processors, available as chiplets and IP. Veyron V1 provides single thread performance and targets data centres, automotive, 5G, AI and client applications. The single socket performance and RISC-V’s open and extensible ...

Following Infineon Technologies’ acquisition of Cypress Semiconductor,  distributor Rutronik will now offer the memories, microcontrollers and other products in the Cypress portfolio. Infineon Technologies acquired Cypress in June 2019 and has added its memory, microcontrollers, sensor, Bluetooth and WiFi technologies to its own offerings. Rutronik was already a fanchised distributor for Infineon and the franchise has been expanded to include the ...

AMD’s latest Ryzen Embedded processor  has been used by congatec in a COM Express Compact module with Type 6 pinout, intended for industrial PCs and thin clients where compute and graphics performance are critical for deep learning. The Ryzen Embedded V2000 processor is at the heart of the conga-TCV2. According to congatec, it doubles performance per W and has twice ...

One of the smallest four-channel power management ICs (PMICs), the NJW4750 is now available from Rutronik UK. It is offered in a 3.4mm x 2.6mm EQFN26 package which incorporates three buck regulators and an LDO for voltage regulation. The distributor also offers the matching evaluation board. One channel is directly connected to the supply voltage of  40V (max) and serves as the ...

At the virtual Nvidia GTC event, founder and CEO, Jensen Huang announced Bluefield data processing units, or DPUs. They are supported by the company’s DOCA architecture and are intended to dramatically increase the networking, storage and security performance of data centres. Bluefield-2 bring the power of the GPU, with silicon and adds AI to the network and storage domain Huang ...

Distributor Farnell is now shipping Nexperia’s power GaN FETs. The FETs can be used in hard switching for AC-DC totem pole power factor correction (PFC) applications, LLC phase shift full-bridge (resonant or fixed frequency) for soft-switching applications, as well as all DC-AC inverter topologies and AC-AC matrix converters using bidirectional switches. GaN FETs provide low RDS(on) and fast switching, together ...

Wireless Gecko SoC families from Silicon Labs available from Mouser Electronics now include the EFR32BG22 (BG22), EFR32MG22 (MG22) and EFR32FG22 (FG22) SoCs. The new SoCs are highly energy efficient, delivering exceptional battery life for a range of Internet of Things (IoT) applications. The Silicon Labs EFR32BG22 single-chips SoCs support Bluetooth 5.2 connectivity, including Bluetooth Mesh, Bluetooth Low Energy and direction-finding with ...

Stealthy, three year-old, processor start-up Groq says it has developed a single chip architecture which can deliver 1PetaOps/sec performance. Groq calls its architecture Tensor Streaming Processor (TSP). Two years back it said it had recruited eight of the ten people who developed Google’s Tensor Processing Unit (TPU). The company has raised $62.3 million in funding. Groq’s architecture is equivalent to ...
