Raspberry Pi has announced its second microcontroller, the RP2350, adding two RISC-V cores alongside improved Arm cores, more ram, and security. Not initially available on its own (ETA pre-year-end), it will first ship as part of the Raspberry Pi Pico 2 single-board microcontroller (right) – which is the same 21 x 51mm size as the original Pico, and priced from ...

Shenzhen MilkV Technology has a chip that combines: 1x 1GHz C906 RISC-V CPU 1x 700MHz C906 RISC-V CPU 1x 1GHz Arm Cortex-A53 CPU 1x 8051 CPU 1x 1Top/s (INT8) neural processor Called SG2002, it also has 256M (byte, probably…) DRAM, a camera interface, video acceleration, an audio codec and a crypto engine. Peripherals include 100Mbit/s Ethernet (with a phy), USB 2.0, ...

Microchip has announced its most secure 32bit microcontrollers – a series of 120MHz Cortex-M33 MCUs for connected things. “Emerging requirements make security mandatory for the majority of IoT connected devices,” said Micrchip v-p Rod Drake, claiming: “The PIC32CK makes it cost effective to provide hardware-based security to mid-range microcontroller applications.” That said, security does not come with every PIC32CK MCU ...

NXP has announced a real-time processor for vehicle central control computers with 16 1.2GHz Arm Cortex-R52 processors. Hardware isolation and virtualisation are provided to allow sharing of on-die hardware between different code blocks without interaction “to support the consolidation of cross-vehicle electronic control units in vehicle central compute applications”, said NXP. “Vehicle functions can be independently managed, including fault handling ...

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. ...

Custom vision-based AI software created on Nvidia’s Tao tool set can be run on Arm based Cortex-M, Cortex-A and Ethos-U microcontrollers according to Edge Impulse, which teamed up with Nvidia to create the work-flow. “Engineers can create computer vision models that can be deployed to hardware including NXP I.MXRT1170, Alif E3, STMicro STM32H747AI and Renesas CK-RA8D1,” according to Edge Impulse. ...

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 ...

Renesas has revealed more on the Arm Cortex-M85 based microcontrollers it announced at Embedded World in May, and started shipping them today. Initial parts are general-purpose and consigned to what Renesas has named the RA8M1 group of the RA8 series. Common specs of RA8M1 parts are: 480MHz Cortex-M85 with Helium and TrustZone, 1 or 2Mbyte programme flash, 12kbyte data flash, ...

Microchip has created a PIC32 family with a 300MHz 32bit Arm Cortex-M7 processor and hardware security, for industrial and consumer devices. “Application designers must consider implementing security functionality in their devices during the development process as security threats evolve and become more sophisticated,” said Microchip. The devices are called PIC32CZ CA90, and their secure module has its own microcontroller running ...

Nordic Semiconductor has announced EEMBC benchmarks for its forthcoming multi-protocol nRF54H20 wireless microcontroller, which combines multiple Arm Cortex-M33 processors and multiple RISC-V coprocessors “optimised for specific types of workloads”, it said, adding that developers will be able to dynamically change between configurations for processing ability or energy efficiency. Configured for high processing efficiency, it got a ULPMark-CM score of 170 ...
