FAQ

What is the maximum operating frequency of the R5F21367CDFP#30?

The R5F21367CDFP#30 supports a maximum external crystal frequency of 20 MHz at VCC = 2.7–5.5 V, achieving a minimum instruction execution time of 50 ns. At reduced supply voltages (1.8–5.5 V), it operates up to 5 MHz with 200 ns minimum instruction time. The high-speed on-chip oscillator also provides programmable frequency adjustment for clock flexibility without external components.

Does the R5F21367CDFP#30 support hardware LIN communication?

Yes, the R5F21367CDFP#30 includes a dedicated hardware LIN module implemented using UART0 and Timer RA, supporting LIN 2.0 and 2.1 protocols. This enables direct connection to LIN transceivers without software bit-banging, reducing CPU overhead and improving timing accuracy for automotive body electronics and industrial sub-networks.

How many analog input channels does the R5F21367CDFP#30 have, and what is their resolution?

The R5F21367CDFP#30 features a 10-bit successive-approximation A/D converter with 12 analog input channels (AN0–AN11). It includes sample-and-hold functionality and sweep mode for sequential conversion - allowing full 12-channel acquisition in under 120 µs at maximum clock rate, suitable for multi-sensor monitoring in real-time control loops.

What low-power modes are available on the R5F21367CDFP#30, and what are their typical current draws?

The R5F21367CDFP#30 offers wait mode (4.0 µA at 3.0 V, 32 kHz XCIN) and stop mode (2.0 µA at 3.0 V), both retaining RAM content and enabling wake-up via external interrupt or RTC alarm. Standard operating mode draws 7.0 mA at 5.0 V/20 MHz. These modes are controlled via system clock registers CM0/CM1 and supported by dedicated oscillation stop detection circuitry.

Is the R5F21367CDFP#30 pin-compatible with other members of the R8C/36C Group?

Yes, all R8C/36C Group MCUs in the PLQP0064KB-A (64-pin LQFP) package - including R5F21364CDFP#30 through R5F2136CCDFP#30 - share identical pin assignments and electrical characteristics. This allows hardware design reuse across memory variants, simplifying platform scaling and firmware porting while maintaining mechanical and thermal compatibility.
