R9A02G021 is the first microcontroller with Renesas 32-bit RISC-V CPU core design

Renesas R9A02G021 is the first MCU group to use the company’s in-house designed 32-bit RISC-V CPU core with 3.27 CoreMark/MHz, RV32I base plus M/A/C/B extensions, and features such as a stack monitor register, a dynamic branch prediction unit, and a JTAG debug interface. Renesas has been making RISC-V chips at least since 2022 with the likes of RZ/Five 64-bit microprocessor and R9A06G150 32-bit voice control ASSP. All those were based on Andes RISC-V cores, but since the company has now designed its own 32-bit core, future Renesas 32-bit RISC-V microcontrollers are all likely to feature the in-house core, starting with the R9A02G021 general-purpose MCU group. Renesas R9A02G021 key features and specifications: RISC-V Core Renesas RISC-V instruction-set architecture (RV32I + MACB + Ziscr, Control and Status Register (CSR) instructions + RISC-V Zifencei Instruction-Fetch Fence) Maximum operating frequency – 48 MHz Debug and Trace – RISC-V External Debug Support cJTAG Debug Port […]

Renesas AIK-RA4E1 and AIK-RA6M3 reference kits are designed for accelerated AI/ML development

Renesas AIK-RA4E1 and AIK-RA6M3 are two new development boards based on RA-series 32-bit microcontrollers. These new dev boards have multiple reconfigurable connectivity functions to accelerate AI and ML design and development time. Both boards appear similar, but the AIK-RA4E1 uses the R7FA4E110D2CFM MCU, features three Pmod ports, and has no Ethernet support. On the other hand, the AIK-RA6M3 utilizes the R7FA6M3AH3CFC MCU, has six Pmod ports, and includes Ethernet support. Both the boards support full-speed USB and CAN bus.

Renesas releases the DA14592, a new dual-core Cortex-M33/M0+ BLE chip with integrated flash

The DA14592 System-on-Chip (Soc) is Renesas’ “lowest power consumption and smallest, multi-core Bluetooth LE device.” According to the company, this chip’s design was achieved by making careful tradeoffs between on-chip memory and die size. The chip offers an ultra-low power mode that uses only 2.3mA when transmitting radio signals at 0dBm and consumes 1.2mA to receive radio signals. It also supports a hibernation mode that uses about 90nA and can extend the operating life of battery-powered products. The active mode is best for processing-intensive products and uses 34µA for every MHz of CPU clock. Projected key applications for the DA14592 chip include crowd-sourced location (CSL) tracking as used in Apple’s Airtags, remote control units, human interface devices, asset tracking, IoT end nodes, data logging, connected health, and activity tracking. Renesas DA14592 specifications: CPU cores: Cortex-M33F running at up to 64MHz as application core Cortex-M0+ at 64MHz as configurable MAC Memory: […]

Renesas RZ/G3S is a 64-bit Arm Cortex-A55/M33 microprocessor with low power consumption and enhanced peripherals

Renesas RZ/G3S 64-bit Arm Cortex-A55 microprocessor (MPU) designed for IoT edge and gateway devices consumes as little as 10µW in standby mode thanks to its Cortex-M33 core(s) and features a PCIe interface for high-speed data transfers with 5G wireless modules. A single-core ARM Cortex-A55 CPU powers the RZ/G3s and can distribute workloads to two sub-CPUs, boosting efficiency in task handling and resulting in fewer components and a smaller system size. The Cortex-A55 core operates at 1.1GHz and is designed to improve power efficiency and performance over its predecessor, the Cortex-A53. The RZ/G3S isn’t Renasas’ first Cortex-A55 product as they have previously released the RZ/A3UL and the RZ/G2L, both powered by the same Cortex-A55 CPU. Additionally, Renesas launched the 64-bit RISC-V RZ/Five processor late last year. The RZ/G3S boasts high-speed interfaces such as PCIe and GbE, a better standby mode, and improved security features which make it suitable for IoT applications […]
