FAQ
What is the maximum operating frequency of the R5F21336CDFP#30 and under what voltage conditions?
The R5F21336CDFP#30 achieves a maximum operating frequency of 20 MHz when powered at VCC = 2.7 V to 5.5 V. At lower supply voltages (1.8 V to 5.5 V), the maximum frequency is reduced to 5 MHz to ensure stable operation. This dual-frequency capability allows flexible power/performance trade-offs in battery-powered or wide-input-voltage designs.
Does the R5F21336CDFP#30 support in-system programming and debugging?
Yes, the R5F21336CDFP#30 includes full on-chip debug functionality and supports in-system flash programming via its UART interface or dedicated debug pins. The on-board flash rewrite capability enables firmware updates without removing the device from the PCB, and the background operation (BGO) function permits concurrent execution and data flash modification.
What are the key differences between the R5F21336CDFP#30 and the R5F21336CNFP variant?
The R5F21336CDFP#30 is the D-version with an operating ambient temperature range of -40°C to +85°C, whereas the R5F21336CNFP is the N-version rated for -20°C to +85°C. All electrical specifications, memory sizes, peripherals, and pinouts are identical-only the temperature qualification differs, making the D-version suitable for industrial or automotive-adjacent environments.
How does the hardware LIN module in the R5F21336CDFP#30 operate?
The R5F21336CDFP#30 implements a hardware LIN 2.0-compliant module by combining Timer RA for baud rate generation and UART0 for serial framing. It handles LIN header transmission, response timing, and checksum calculation autonomously-reducing CPU load and ensuring protocol compliance without software bit-banging overhead.
What low-power modes are available on the R5F21336CDFP#30 and their typical current consumption?
The R5F21336CDFP#30 offers wait mode (3.5 µA at 3.0 V with 32 kHz XCIN clock) and stop mode (2.0 µA at 3.0 V), both retaining RAM content and enabling wake-up via interrupts or external events. These modes are optimized for battery-backed real-time clock operation and intermittent sensor polling in energy-constrained applications.
