Product details
Overview
R9A02G0214CNH#BA0 from Renesas is a 32-bit RISC-V microcontroller featuring a 48 MHz ultra-low-power core, 128 KB code flash, 16 KB SRAM (12 KB parity + 4 KB ECC), 12-bit ADC with 8 input channels, dual 8-bit DACs, and integrated safety features including SRAM ECC, CAC, CRC, DOC, TRNG, and IWDT. It targets industrial sensor nodes and battery-powered control systems operating from −40°C to +125°C.
For engineers reviewing the R9A02G0214CNH#BA0 datasheet, R9A02G0214CNH#BA0 pinout, R9A02G0214CNH#BA0 application, or R9A02G0214CNH#BA0 equivalent, key selection considerations include its 32-pin HWQFN package, 26 GPIOs, reduced SAU (3 UART/3 SPI/3 I²C), single IICA, absence of UARTA and sub-clock oscillator, and KINT support for 2 keys - all confirmed for this specific variant.
Technical Context
This MCU implements the RISC-V RV32I base ISA with M, A, C, Zifencei, Ziscr, and B extensions (Zba/Zbb/Zbs), supporting dynamic branch prediction and machine-mode privilege. Its clock system integrates HOCO/MOCO/LOCO oscillators with trim, plus EXTAL and dedicated IWDT oscillator.
Safety architecture includes hardware-level error detection (SRAM ECC/parity, illegal access, register write protection), fault-tolerant timing (IWDT with independent 15 kHz clock), and diagnostic peripherals (CAC, CRC, DOC, TRNG). The Event Link Controller (ELC) enables CPU-free peripheral-to-peripheral event routing.

What analog peripherals are included in the R9A02G0214CNH#BA0 and how many channels do they support?
The R9A02G0214CNH#BA0 includes a 12-bit successive approximation ADC (ADC12) with 8 selectable input channels (ANI0–ANI5, ANI16–ANI19), two 8-bit DACs (DACOUT0/DACOUT1), two comparators (CMP), and an on-die temperature sensor (TSN). These peripherals are fully supported in the 32-pin HWQFN variant and enable local analog signal processing without external components.
What is the package type and pin count of the R9A02G0214CNH#BA0, and does it support cJTAG debugging?
The R9A02G0214CNH#BA0 uses a 32-pin HWQFN package (5 mm × 5 mm, 0.5 mm pitch) with exposed thermal pad.
