Bos Semiconductors has shipped its first chiplet-based NPU samples to automotive OEMs. It is a version of the company’s Eagle-N branded processor. “Eagle-N 250Top/s NPU is designed for ADAS (driver-assistance systems), automated driving and in-vehicle infotainment,” said Bos. “Leveraging a chiplet-based architecture, Eagle-N can scale up to 2,000+Top/s.” ISO26262 ASIL-B is the automotive risk target. Neural processor intellectual property within ...

Renesas has added dual-bank memory for over-the-air updates to its range of MCUs with a segment-style LCD driver and a capacitive touch controller. The new parts are the RL78/L23 group, and have the company’s in-house RL78 low-power 16bit three-stage pipeline CISC core, running at its maximum of 32MHz. This is supported by up to 512kbyte of flash, up to 32kbyte ...

Rohm has released hybrid analogue-digital controlled design for a 24V 4A output mains PSU built around its ML62Q2035 16bit RISC MCU. The design, called REF67004 and implemented on the LogiCoA003-EVK-001 evaluation board, incorporates a critical conduction mode PFC (power factor correction) stage followed by an isolated quasi-resonant fly-back converter. “Analog-controlled power supplies are widely used in small to medium-power industrial ...

Taiwanese chip maker Nuvoton Technology has announced a 24MHz 8051-style series of MCUs for industrial automation, motor control, LED dimming and home appliances. Called the MG51 series, the parts execute one instruction per clock cycle (the company’s ‘1T’ 8051 core), compared with the original 8051 which took many clock cycles to execute an instruction. “It integrates rich communication and control ...

The European electronic components distribution market is suffering from a declining automotive sector, reports DMASS Europe. The electronic components distribution industry body represents approximately 85% of the European components DTAM. DMASS said that European semiconductor distribution sales in Q2 2025 fell 14% compared to Q2 2024. Austria experiencing the steepest drop (36.6%) followed by France (20%), Germany and Ireland both ...

A company called Efficient Computer is claiming to run microcontroller tasks with 10- to 100-times better power efficiency than standard microcontrollers, with an architecture to be implemented in an IC called the Electron E1. Based in Pennsylvania, most of its founders come from Carnegie Mellon University. Reprogrammable hardware dubbed the ‘Fabric’ does the processing, and programming has to be through ...

Renesas is aiming at edge computing applications that need AI and up to two displays with its latest MCU. The top-end 64-bit RZ/G3E has a 1.8GHz quad-core Arm Cortex-A55,  a 512Gop/s Ethos-U55 NPU for AI and a Cortex-M33. External memory is handled via a 32-bit LPDDR4/LPDDR4X bus with ECC. “This architecture runs AI applications such as image classification, object recognition, ...

Mouser is stocking a 2.2 x 3mm Bluetooth MCU from Renesas, which can run from a 1.55V silver oxide cell. Called DA14535, it is built around an Arm Cortex-M0+ and implements Bluetooth LE 5.3. “By adding six external passives, a crystal oscillator, a power source, plus a 2.4GHz antenna, designers can build a complete Bluetooth Low Energy system for applications ...

Renesas has introduced a 64MHz Arm Cortex-M23 MCU for motor control. Called RA2T1, the “devices are specifically designed for single-motor applications such as fans, power tools, vacuum cleaners, refrigerators, printers and hair dryers”, it said. Peripherals include a three-channel sample-and-hold to simultaneously measure phase current in brushless dc motors, and pulse-width modulators that can insert dead-times and produce asymmetric complementary ...

Renesas has introduced a high-end AI MCU family with triple processors and security. The highest spec devices in the ‘RA8P1’ microcontroller family combine a 1GHz Arm Cortex-M85 processor with a 256 MAC/cycle 500MHz Arm Ethos-U55 neural processing unit and a 250MHz Cortex-M33 CPU. “This combination delivers CPU performance of over 7,300 CoreMarks and AI performance of 256Gop/s,” according to the ...
