FAQ

What is the maximum operating frequency and core architecture of the R9A02G0214CNE#BA0?

The R9A02G0214CNE#BA0 features a Renesas-custom RISC-V 32-bit core compliant with RV32I base ISA plus M, A, C, Zifencei, Ziscr, and B extensions, operating at a maximum frequency of 48 MHz. This architecture delivers deterministic real-time performance with support for dynamic branch prediction and machine-mode privilege, and is validated for use in functional safety applications up to ASIL-B per ISO 26262.

Does the R9A02G0214CNE#BA0 support hardware-based functional safety features?

Yes, the R9A02G0214CNE#BA0 integrates multiple hardware safety mechanisms including Clock Frequency Accuracy Measurement Circuit (CAC), SRAM parity/ECC error detection, flash area protection, Independent Watchdog Timer (IWDT) with dedicated oscillator, illegal memory access detection, register write protection (PRCR), and True Random Number Generator (TRNG). These features collectively support diagnostic coverage required for IEC 61508 SIL2 and ISO 26262 ASIL-B certification.

What analog peripherals are included in the R9A02G0214CNE#BA0 and how are they configured?

The R9A02G0214CNE#BA0 includes a 12-bit successive approximation ADC with 10 selectable input channels (ANI0–ANI5, ANI16–ANI19), two 8-bit DACs (DACOUT0/DACOUT1), two comparators (CMP0/CMP1) with internal/external reference support, and an on-die temperature sensor (TSN). ADC inputs accept internal references (VCC, bandgap) or external signals; DAC outputs can drive comparator references or external loads up to 8 mA; all analog blocks share dedicated AVREFP/AVREFM supply pins for noise isolation.

How many communication interfaces does the R9A02G0214CNE#BA0 provide and what protocols are supported?

The R9A02G0214CNE#BA0 provides two Serial Array Units (SAU) supporting up to six simplified SPI, three UART, and six simplified I²C channels; two I²C Bus Interfaces (IICA0/IICA1); two UARTA modules; and one Remote Control Signal Receiver (REMC). It does not include native CAN or USB interfaces. Communication is further enhanced by Data Transfer Controller (DTC) for autonomous data movement and Event Link Controller (ELC) for hardware-triggered peripheral chaining.

What package type and pin count does the R9A02G0214CNE#BA0 use, and what are its thermal specifications?

The R9A02G0214CNE#BA0 uses a 48-pin HWQFN package (7 mm × 7 mm, 0.5 mm pitch) with exposed thermal pad, rated for operation from -40°C to +125°C ambient temperature. Its absolute maximum junction temperature is 140°C, and thermal design must account for θja (junction-to-ambient) per layout - Renesas recommends minimum 4 thermal vias under the exposed pad and tight decoupling (0.1 µF ceramic) at each VCC/VSS pair to maintain reliability in high-temperature industrial environments.
