FAQ

What is the maximum operating frequency and supply voltage range for the R5F2L368CNFP#30?

The R5F2L368CNFP#30 operates at up to 20 MHz when supplied with 2.7–5.5 V, or at 5 MHz down to 1.8 V for ultra-low-voltage applications. 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. The device maintains full peripheral functionality across this entire voltage range.

Does the R5F2L368CNFP#30 support in-system programming and debugging?

Yes, the R5F2L368CNFP#30 includes an on-chip debug interface supporting full in-circuit debugging via single-wire connection, flash programming, breakpoint insertion, and real-time register/variable inspection. It also enables background operation (BGO) for data flash rewriting during active program execution-critical for field-upgradable firmware in deployed appliances without service interruption.

How many analog-to-digital converter (ADC) channels does the R5F2L368CNFP#30 provide, and what is their resolution?

The R5F2L368CNFP#30 integrates a 10-bit successive-approximation ADC with 10 input channels, including sample-and-hold circuitry and hardware sweep mode for automatic sequential conversion. All 10 channels are accessible via dedicated pins (AN0–AN9) mapped to P0 and P13 ports, supporting simultaneous temperature, voltage, and current sensing in multi-sensor appliance designs.

What LCD display capabilities does the R5F2L368CNFP#30 offer?

The R5F2L368CNFP#30 supports LCD driving with up to 8 common (COM) and 32 segment (SEG) outputs, configurable for static, 1/2, 1/3, 1/4, or 1/8 duty cycles and 1/2 or 1/3 bias. It integrates VL1–VL4 bias voltage pins and CL1/CL2 clock inputs, eliminating external bias generators and enabling direct connection to character or segmented displays used in microwave ovens and refrigerators.

Is the R5F2L368CNFP#30 pin-compatible with other R8C/L3x Group MCUs?

No-R5F2L368CNFP#30 is not pin-compatible with R8C/L35C, L38C, or L3AC Group devices due to differing pin counts (52/64/80/100 pins) and I/O mappings. However, it shares the same 64-pin LQFP footprint (PLQP0064KB-A) with other R8C/L36C variants like R5F2L367CNFP#30 and R5F2L36ACNFP#30, enabling family-based design reuse within the L36C series.
