FAQ

What is the maximum operating frequency and corresponding performance of the R5F1017CANA#U0?

The R5F1017CANA#U0 operates at up to 32 MHz with an on-chip high-speed oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs in high-speed mode, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation. This dual-speed capability makes the R5F1017CANA#U0 suitable for applications requiring both responsive control and extended battery life.

Does the R5F1017CANA#U0 include data flash memory, and what are the implications for firmware design?

No, the R5F1017CANA#U0 contains 32 KB of code flash memory and 2 KB of RAM but zero data flash memory. This means nonvolatile storage of runtime parameters, calibration data, or event logs requires external EEPROM or FRAM. Firmware must be designed to avoid reliance on on-chip data flash features like background operation or 1 million write-cycle endurance - a key distinction from variants like R5F1007CANA#U0.

What package type and pin count does the R5F1017CANA#U0 use, and how does it impact PCB layout?

The R5F1017CANA#U0 uses a 24-pin HWQFN package measuring 4 × 4 mm with 0.5-mm pitch. Its small footprint and exposed thermal pad simplify layout in space-constrained applications like smart meters and sensor modules. The pinout includes dedicated analog inputs (P20–P22), serial interface multiplexing (P30–P32), and multiple VDD/VSS pairs - requiring careful decoupling and grounding per Renesas layout guidelines to maintain ADC accuracy and noise immunity.

How does the low-power capability of the R5F1017CANA#U0 compare across its sleep modes?

The R5F1017CANA#U0 offers three primary low-power states: HALT mode draws 66 μA/MHz, STOP mode consumes just 0.57 μA while retaining RTC and LVD functionality, and SNOOZE mode enables background ADC conversion during CPU sleep. These modes allow precise trade-offs between responsiveness and energy use - for example, STOP mode supports decade-long battery life in tamper-detection circuits, while SNOOZE enables periodic sensor sampling without full wake-up overhead.

Which communication interfaces are integrated into the R5F1017CANA#U0, and how are they allocated on the 24-pin package?

The R5F1017CANA#U0 integrates UART, I²C, and CSI (Simplified SPI) interfaces, all multiplexed onto P30–P32 pins. P30 serves as SCK00/SCL00, P31 as SI00/RxD0/SDA00, and P32 as SO00/TxD0/SA00 - enabling flexible configuration for serial communication protocols without additional GPIO overhead. This pin sharing requires careful initialization sequencing but maximizes peripheral utility within the 24-pin constraint.
