Renesas is aiming at industry with a microcontroller that combines an EtherCAT slave controller, motor control capability and a 240MHz version of its RX core – delivering a 1396 CoreMark. These attributes are being offered in the RX72M Group, which the fims is describing as “the new flagship product group for the Renesas RX family”. Applications are expected in industrial robots, ...

Knowles has announced a dual-core audio processor chip for multi-microphone edge processing  – for example, for local spoken-word control of products. Called IA8201, it includes a pair of modified Tensilica Xtensa LX5 cores: ‘DeltaMax’ is a 128bit four-way floating-point SIMD DSP core, with Knowles instruction set extensions for high performance frame-based audio processing and 16-way SIMD deep neural network acceleration. ...

ST is sampling STM32H7 MCUs which claim to be the industry’s highest-performing Arm Cortex-M general-purpose MCUs. The new devices leverage a 480MHz version of the Cortex-M7, the highest performing member of Arm’s Cortex-M family, and add a 240MHz Cortex-M4 core. With an efficient L1 cache, and adaptive real-time ART Accelerator, the MCUs claim speed records at 1327 DMIPS and 3224 CoreMark ...

The STM32G4 Series combines a 32-bit Arm Cortex-M4 core (with FPU and DSP instructions) running at 170 MHz combined with 3 different hardware accelerators: ART Accelerator, CCM-SRAM routine booster and mathematical accelerators. The STM32G4 Series also offers: Rich advanced analog peripherals (comparator, op-amps, DAC) ADC with hardware oversampling (16-bit resolution) Dual-bank Flash memory with error-correcting code (ECC) (supports in-field firmware ...

STMicroelectronics has created MCU peripherals for improved digital PSUs and motor control: hardware trigonometric and filtering accelerators, a high-resolution timer, a fast analogue comparator and a low-error op-amp. Silicon carbide and gallium nitride converters are a particular target market. Released today, they are all built into STM32G4, a 170MHz Arm Cortex-M4 cored microcontroller – rated at 213D MIPS, 550 CoreMark ...

Renesas is claiming 10nV/°C offset drift, 1ppm/°C gain drift and 30nV RMS noise from the analogue front-end (AFE) of its latest microcontrollers “a level that could previously only be achieved by combining dedicated A/D converter circuits with high-precision operational amplifier ICs”, it said. Included monolithically alongside a 32MHz 32-bit RXv2 core, the AFE will appear in the firm’s RX23E-A Group devices, ...

Renesas has added a hardware motor control accelerator to 32bit microcontrollers that already achieve a 1,160 CoreMark from EEMBC – the highest score for a 5V MCU operating at 200MHz, claims Renesas. Within the RX72T group, as the chips will be known, the accelerator enableshigh-speed position control and speed control calculations required for implementing servo motor control. “This allows the ...

STMicroelectronics has expanded its STSPIN32 programmable motor controller family with a system-in-package brushless-dc (BLDC) motor battery-operated power tools. STSPIN32F0B as it will be known integrates an op-amp for current sensing through a single resistor in the negative return wire (diagram below). See our full PCIM 2019 news roundup » On-board is a 48MHz STM32F031x6 MCU (Arm Cortex-M0 core) capable of ...
