Description
The MCU in this series incorporates an energy-efficient and performant Renesas RISC-V 32-bit core, that is particularly well-suited for cost-sensitive and low-power applications. It features 128KB code flash memory, 4KB data flash, 16KB SRAM with ECC support, many timers and serial connectivity interfaces, a high number of IOs with output current control, and rich analog functionality (12-bit A/D Converter, DAC, comparator). The device supports 125°C temperature operation and can be delivered in 16 WLCSP, 24, 32 and 48 QFN package options. Renesas provides a complete free-of-charge development ecosystem including e2 studio IDE, code generator, compiler toolchain, flashing tools, and application notes to assist the end user in developing and deploying this new technology in a product. Additional commercial environments like IAR Embedded Workbench and SEGGER Embedded Studio are available for this MCU.
