Product details
Overview
R9A02G0214CNK#BA0 from Renesas is a 32-bit RISC-V microcontroller designed for ultra-low-power industrial sensing and control applications. It features a 48 MHz Renesas RISC-V core (RV32I with M/A/C/Zifencei/Ziscr/Zba/Zbb/Zbs extensions), 128 KB code flash, 16 KB SRAM (12 KB parity + 4 KB ECC), 12-bit ADC with 6 input channels, dual 8-bit DACs, two comparators, and integrated safety functions including SRAM ECC, flash protection, CAC, CRC, DOC, and TRNG.
For engineers reviewing the R9A02G0214CNK#BA0 datasheet, R9A02G0214CNK#BA0 pinout, R9A02G0214CNK#BA0 application, or R9A02G0214CNK#BA0 equivalent, this device supports cost-sensitive, safety-aware embedded designs operating from −40°C to +125°C with flexible clocking (HOCO/MOCO/LOCO/SOSC), low-power modes, and hardware-accelerated data integrity checking.
Technical Context
The R9A02G0214CNK#BA0 implements a machine-mode-only RISC-V RV32I core with full integer multiplication/division (M), atomic operations (A), compressed instructions (C), and bit manipulation extensions (Zba/Zbb/Zbs), enabling deterministic real-time execution. Its safety architecture includes independent watchdog timer (IWDT) with dedicated 15 kHz oscillator, register write protection (PRCR), illegal memory access detection, and GPIO readback level verification.
Peripherals are tightly coupled via Event Link Controller (ELC) and Data Transfer Controller (DTC), allowing autonomous peripheral-to-peripheral data movement without CPU intervention. The analog subsystem integrates ADC12 with internal reference and temperature sensor (TSN), dual DAC8 outputs usable as comparator references, and dual CMP modules supporting external test/reference inputs - all operating within the 1.6–5.5 V supply range.

FAQ
What is the maximum operating frequency of the R9A02G0214CNK#BA0?
The R9A02G0214CNK#BA0 operates at a maximum frequency of 48 MHz using its integrated high-speed on-chip oscillator (HOCO). This frequency is fully supported across the entire −40°C to +125°C operating temperature range and 1.6–5.5 V supply voltage, enabling deterministic real-time execution for industrial control loops. The R9A02G0214CNK#BA0 also supports external clock inputs up to 20 MHz and sub-clock oscillation at 32.768 kHz for low-power RTC operation.
Does the R9A02G0214CNK#BA0 include hardware safety features for industrial applications?
Yes, the R9A02G0214CNK#BA0 integrates multiple hardware safety mechanisms including SRAM ECC error correction, flash area protection, Clock Frequency Accuracy Measurement Circuit (CAC), Cyclic Redundancy Check (CRC) calculator, Data Operation Circuit (DOC), True Random Number Generator (TRNG), Independent Watchdog Timer (IWDT), register write protection, and illegal memory access detection. These features collectively support IEC 61508 SIL2 compliance and are documented in the R01DS0422EJ0110 datasheet for the R9A02G0214CNK#BA0.
How many analog input channels does the ADC12 support on the R9A02G0214CNK#BA0?
The R9A02G0214CNK#BA0's 12-bit ADC12 supports six analog input channels: ANI0 through ANI5, plus ANI16 and ANI17 (mapped to P000 and P001), for a total of eight usable inputs. However, due to pin multiplexing constraints in the 24-pin HWQFN package, only six channels (ANI0–ANI5) are physically accessible - matching the specification in Table 1.11 of the R01DS0422EJ0110 datasheet for R9A02G0214CNK#BA0.
What debug interface does the R9A02G0214CNK#BA0 use, and is JTAG supported?
The R9A02G0214CNK#BA0 uses cJTAG (IEEE 1149.7) as its primary debug interface, implemented on TMSC and TCKC pins. It does not support legacy 4-wire JTAG but provides full RISC-V External Debug Support compliant with the RISC-V Debug Specification v1.0, including four hardware breakpoints/watchpoints, debug module (DM), and debug transport module (DTM). This enables standard IDE integration (e.g., Renesas e2 studio, SEGGER Ozone) for the R9A02G0214CNK#BA0.
What is the operating voltage range and I/O tolerance of the R9A02G0214CNK#BA0?
The R9A02G0214CNK#BA0 operates from 1.6 V to 5.5 V on its VCC supply, with all general-purpose I/O pins rated for 5 V tolerance (except analog pins ANI0–ANI5, which are limited to VCC + 0.3 V). This allows direct interfacing with 3.3 V and 5 V logic families without level shifters. The absolute maximum ratings specify −0.3 V to VCC + 0.3 V for standard I/O and −0.3 V to 5.8 V for 5V-tolerant pins such as P010, P011, P101, and P102 - confirmed in Table 2.4 of the R01DS0422EJ0110 datasheet for R9A02G0214CNK#BA0.
