R5F21255SNFP#V2 Frequently Asked Questions (FAQ)

  • The recommended power-on sequence is to apply VCC first, followed by VDD, and then the clock signal. This ensures that the internal voltage regulators and clock circuitry are properly initialized.

  • The clock settings can be configured using the Clock Control Register (CCR) and the Clock Frequency Register (CFR). The CCR sets the clock source and mode, while the CFR sets the clock frequency. Refer to the user manual for specific register settings and values.

  • The maximum operating temperature range for the R5F21255SNFP#V2 is -40°C to +125°C. However, it's recommended to operate the device within the industrial temperature range of -40°C to +85°C for optimal performance and reliability.

  • The R5F21255SNFP#V2 has a built-in watchdog timer (WDT) that can be enabled and configured using the Watchdog Timer Control Register (WTCR). The WDT can be set to reset the device or generate an interrupt if the timer expires.

  • The maximum current consumption of the R5F21255SNFP#V2 depends on the operating frequency and voltage. According to the datasheet, the maximum current consumption is approximately 350 mA at 100 MHz and 3.3 V.
