Description:The M16C/64 Group is supported only for customers who have already adopted these products. The RX130, RX651 Groups are recommended for new designs.
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 circuits are properly initialized.
The clock settings can be configured through 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 R5F3640DDFA#U0 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 R5F3640DDFA#U0 has a built-in watchdog timer (WDT) that can be enabled and configured through the Watchdog Timer Control Register (WTCSR). The WDT can be set to reset the device or generate an interrupt upon timeout. Refer to the user manual for specific register settings and values.
The maximum current consumption of the R5F3640DDFA#U0 depends on the operating frequency, voltage, and mode. According to the datasheet, the maximum current consumption is approximately 350 mA at 1.8 V and 100 MHz. However, this value may vary depending on the specific application and usage.
