FAQ

What is the maximum operating frequency and CPU performance of the R5F5630ACDFC#V0?

The R5F5630ACDFC#V0 operates at a maximum frequency of 100 MHz and delivers 165 DMIPS of processing performance using the RXv1 32-bit CPU core. Its 5-stage pipeline, variable-length instruction set, and on-chip FPU enable efficient execution of real-time control algorithms. The R5F5630ACDFC#V0 achieves this performance with zero-wait-state access to both 768 KB flash and 96 KB SRAM, ensuring deterministic timing for time-critical tasks.

Does the R5F5630ACDFC#V0 include a CAN interface?

No, the R5F5630ACDFC#V0 does not include a CAN module. The 'C' in the part number suffix indicates CAN omission, distinguishing it from variants like R5F5630ADDFC#V0 (which includes CAN). This makes the R5F5630ACDFC#V0 suitable for applications requiring USB, SCI, I2C, and RSPI-but not CAN-reducing system complexity and cost where CAN is unnecessary.

What are the supported debug interfaces for the R5F5630ACDFC#V0?

The R5F5630ACDFC#V0 supports two standardized on-chip debug interfaces: JTAG (using TRST#, TMS, TDI, TCK, TDO pins) and Renesas' two-wire FINE interface (via FINED and FINEC pins). Both are fully compatible with Renesas E1 and E20 emulators. The R5F5630ACDFC#V0 does not require external debug probes beyond these standard connections, enabling seamless firmware development and real-time trace analysis.

What is the operating temperature range and supply voltage specification for the R5F5630ACDFC#V0?

The R5F5630ACDFC#V0 is rated for industrial operation from -40°C to +85°C (D version) and requires a single 2.7 V to 3.6 V supply on VCC. It supports battery backup via VBATT (2.3–3.6 V) for RTC retention and includes low-voltage detection (LVD) with programmable thresholds. The R5F5630ACDFC#V0 draws only 500 µA/MHz in active mode, making it suitable for thermally constrained or energy-conscious designs.

How many analog-to-digital converter channels does the R5F5630ACDFC#V0 provide, and what are their resolutions?

The R5F5630ACDFC#V0 integrates two independent A/D converters: a 12-bit SAR unit with 21 input channels and a 10-bit SAR unit with 8 input channels. Both include sample-and-hold circuits and support conversion start via software, timer trigger (MTU/TPU/TMR), or external signal. The 12-bit A/D achieves 1.0 µs conversion time at 50 MHz PCLK, and the on-die temperature sensor feeds into the 12-bit A/D for ±1°C thermal monitoring.
