Renesas RA0E3 Arm Cortex-M23 MCU is a stripped-down RA0E1 for cost-sensitive applications

Back in 2024, Renesas first released the RA0E1, an ultra-low-power Cortex-M23 MCU designed for cost-sensitive applications, followed by the RA0E2, with extended temperature range support (-40°C to +125°C). The company has expanded its lineup with the RA0E3, a stripped-down version of the RA0E1 with less memory, fewer peripherals, and fewer GPIOs, designed for small and budget-focused applications for sensing, motor assist, safety, and basic system control. The MCU retains the same 32 MHz Arm Cortex-M23 (Armv8-M) core but now comes with 16KB flash and 2KB SRAM. It features an 8-channel 16-bit TAU timer, a 32-bit interval timer, a 10-bit ADC with a temperature sensor, a Data Transfer Controller, and serial interfaces including SPI, I²C, and UART (with LIN support). Additionally, it comes with up to 17 GPIOs, pull-ups, open-drain support, and built-in clock sources. It has an operating voltage range of 1.6V to 5.5V and supports −40°C to +125°C operation

Renesas RA6W1/RA6W2 Cortex-M33 wireless MCUs offer dual-band Wi-Fi 6, BLE, Matter, 15-year availability

Renesas has added the RA6W1 (Wi-Fi 6) and the RA6W2 (Wi-Fi 6 + BLE) MCUs to its high-performance RA6 family, adding dual-band Wi-Fi 6 and Bluetooth LE, as well as Matter connectivity to the series. Both models feature a 160 MHz Arm Cortex-M33 core, dual-band Wi-Fi 6 with WPA3 security, on-chip PA/LNA/RF switch, and a full TCP/IP stack for fast connectivity. They integrate up to 704 KB SRAM, 256 KB ROM, and support eMMC/SD, O-QSPI, and QSPI for external flash and/or PSRAM. The series also includes generic peripherals like SPI, I²C, I²S/PDM, SDIO, 12-bit ADCs, PWM timers, and up to 28 GPIOs. Offered in compact QFN/WLCSP packages, the RA6W1/2 MCUs target smart home, wearables, industrial, and consumer IoT markets where long battery life and wireless connectivity are essential. Renesas RA6W1 specifications: MCU core – Arm Cortex-M33 @ up to 160 MHz, Armv8-M architecture with MPU and SysTick Memory & Storage
