R5F21254SDFP#V2 Frequently Asked Questions (FAQs)

  • The recommended power-on sequence is to apply VCC first, followed by VCCPLL, and then VCCIO. This ensures proper power-up of the device and prevents any potential damage.
  • The clock settings can be configured using the Clock Control Register (CCR) and the PLL Control Register (PCR). The CCR sets the clock source and frequency, while the PCR configures the PLL settings. Refer to the datasheet for specific register settings and values.
  • The maximum operating frequency of the R5F21254SDFP#V2 is 240 MHz. However, this frequency may vary depending on the specific application and operating conditions.
  • The R5F21254SDFP#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 upon timeout.
  • The VCCPLL power pin is used to power the internal PLL (Phase-Locked Loop) circuitry. It requires a separate power supply voltage, typically 1.2V, to ensure proper PLL operation.
