FAQ

What is the maximum operating frequency and supply voltage range for the R5F2L35CCDFP#30?

The R5F2L35CCDFP#30 operates at up to 20 MHz when supplied with 2.7–5.5 V, and supports reduced-frequency operation down to 5 MHz at 1.8–5.5 V for ultra-low-power modes. Its minimum instruction execution time is 50 ns at 20 MHz and 200 ns at 5 MHz, enabling deterministic real-time response in appliance control loops.

Does the R5F2L35CCDFP#30 support in-system programming and secure firmware updates?

Yes, the R5F2L35CCDFP#30 supports on-board flash rewrite with background operation (BGO), allowing firmware updates while the application runs from other memory regions. It includes ROM code protection and ID code check features to prevent unauthorized access or cloning of embedded firmware.

How many analog-to-digital converter channels does the R5F2L35CCDFP#30 have, and what resolution do they offer?

The R5F2L35CCDFP#30 integrates a 10-bit successive-approximation ADC with 10 input channels, including sample-and-hold circuitry and hardware sweep mode for automatic channel scanning - sufficient for simultaneous monitoring of temperature, voltage, and current sensors in consumer appliance subsystems.

Can the R5F2L35CCDFP#30 drive a 4-digit 7-segment LCD display directly?

Yes, the R5F2L35CCDFP#30's LCD controller supports up to 4 common outputs and 24 segment outputs, which fully covers standard 4-digit 7-segment plus decimal point and colon displays (requiring ≤ 4 COM and ≤ 28 SEG). Its integrated VL1–VL4 outputs generate required bias voltages without external components.

What communication interfaces are available on the R5F2L35CCDFP#30 for connecting to external peripherals?

The R5F2L35CCDFP#30 provides UART0, UART1, and UART2 (with I²C mode), one shared I²C-bus/SSU channel, and hardware LIN support using UART0 and Timer RA - enabling reliable communication with displays, sensors, motor drivers, and master controllers in appliance and office equipment designs.
