FAQ

What is the maximum operating frequency of the R5F213G4CDSP#W4?

The R5F213G4CDSP#W4 supports a maximum external crystal frequency of 20 MHz at VCC = 2.7–5.5 V, enabling instruction execution at 50 ns minimum cycle time. At lower voltages (1.8 V), max frequency drops to 5 MHz with 200 ns minimum instruction time - verified in Table 1.1 of the R01DS0036EJ0100 datasheet.

Does the R5F213G4CDSP#W4 support hardware LIN communication?

Yes, the R5F213G4CDSP#W4 integrates a dedicated hardware LIN module that combines UART0 and TimerRA to implement full LIN 2.0/2.1 protocol - including auto-baud detection, checksum calculation, and frame timing - without CPU intervention, as confirmed in Section 1.1 and Figure 1.2 of the datasheet.

What is the purpose of the Background Operation (BGO) feature in the R5F213G4CDSP#W4?

The BGO feature allows the R5F213G4CDSP#W4 to execute application code while simultaneously erasing or programming data flash blocks - critical for over-the-air firmware updates and real-time data logging. This avoids CPU stalls and maintains deterministic timing, as detailed in Section 1.1 and Table 1.2.

Can the R5F213G4CDSP#W4 operate from a 1.8 V supply?

Yes, the R5F213G4CDSP#W4 is fully specified down to 1.8 V at reduced frequency (5 MHz), supporting ultra-low-power applications such as battery-backed sensor nodes. Its voltage detection circuit monitors VCC and triggers reset if supply falls below programmable thresholds, per Table 1.1 and Section 1.1.2.

How many analog input channels does the R5F213G4CDSP#W4 ADC support?

The R5F213G4CDSP#W4 integrates a 10-bit successive-approximation ADC with eight analog input channels (AN0–AN11, excluding AN2–AN4), supporting simultaneous sampling in sweep mode and external trigger (ADTRG) for synchronized acquisition - as defined in Table 1.2 and Section 1.1.2.
