GigaDevice has received IEC 61508 SC3 (SIL 2/SIL 3) functional safety certification for the software test libraries of a pair of Cortex-M33 MCU series. “With growing emphasis on safety across industrial automation, functional safety has become a critical consideration in embedded system design,” according to GigaDevice. Certified by TÜV Rheinland, the software test libraries monitor microcontroller modules in real time ...

Direct Insight is to offer KaRo’s 27 x 27mm system on module that pairs a 1.2GHz dual-core Arm Cortex-A35 processor with 1Gbyte of LPDDR4, 4Gbyte of eMMC flash and an NPU. Called QSMP-23, “this solder-down module delivers an industrial-grade 64bit solution for secure industry 4.0 and machine learning edge computing applications that require multimedia capabilities,” said Direct Insight MD David ...

Renesas has introduced 1GHz Arm Cortex-M85 microcontrollers, with or without a 250MHz Cortex-M33 co-processor. “The new MCUs deliver 7,300 Coremarks of compute performance. The optional Cortex-M33 core can act as a housekeeping MCU, executing system tasks while the high performance core stays in sleep mode,” said the company. “They are built on the same high-speed, low-power 22-nm ULL process used ...

TÜV SÜD has ASIL certified two RISC-V processors for ISO 26262 automotive functional safety: Codasip’s L735 up to ASIL-B, and its L739 up to ASIL-D. “In addition to functional safety certification, both products are also compliant with ISO/SAE 21434, the international standard for cybersecurity in automotive development,” according to Codasip. Both cores have a multi-issue in-order microarchitecture. L735 includes error-correcting ...

Renesas has come out with a new MCU group for high-end motor control designated RA8T2. Based on a 1 GHz Arm Cortex-M85 processor with an optional 250 MHz Arm Cortex-M33 processor, the RA8T2 devices deliver real-time control of high-end motors in industrial equipment, robots, and other systems where high-speed precision operation is required. The optional Cortex-M33 processor enables customers to ...

Nordic Semiconductor is aiming at Bluetooth LE and Matter applications with a wireless microcontroller equipped with 2Mbyte if non-volatile memory and 512kbyte of ram. Made on a 22nm process, nRF54LM20A, will have a 128MHz Arm Cortex-M33 main processor and a RISC-V co-processor, USB and up to 66 GPIOs. The 2.4GHz radio will support Bluetooth LE channel-sounding and Matter-over-Thread, and will ...

EnSilica and Codasip have announced a strategic partnership to bring CHERI cybersecurity to automotive, critical national infrastructure, defence and aerospace applications EnSilica, the ASIC specialist, and Codasip, a provider of functionally-safe and cyber-resilient RISC-V CPUs, will enable custom ASICs incorporating CHERI (Capability Hardware Enhanced RISC Instructions), Post-Quantum Cryptographic (PQC) acceleration, and advanced system-level security and safety features. CHERI’s hardware security ...

Ambient Scientific is demonstrating AI applications running on coin cell batteries at Electronica India this week, using combined analogue and digital processing to save power. Locally-processed local fall detection, voice recognition and face ID will be running on its ‘GPX10 Pro’ IC. Inside, AI processing is performed in two sets of five cores (called ‘MX8’) in two separate power domains. ...

Texas Instruments has optimised a pair of DSPs for field-oriented motor control in domestic appliances such as washing machines, vacuum cleaners and lawn mowers. “Their capabilities, including high-speed sensor-less field-oriented control, high-torque zero-speed start-up and vibration compensation, deliver responsive motor control for everyday applications,” claimed the company. The parts are F28E120SC and F28E120SB, differing only in flash memory size: either ...

Silicon Labs has cherry-picked its FG23 family of sub-GHz wireless MCUs to create the less capable FG23L family. “FG23L is optimised for the simple applications that have been the backbone of proprietary wireless networks,” SiLabs marketing manager Chad Steider told Electronics Weekly. “These applications, like smart city sensors, home automation and security sensors, as well as fobs and remotes, don’t ...
