What is the maximum operating frequency and supply voltage range for the R5F21357CDFP#10?
The R5F21357CDFP#10 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 V minimum supply. This dual-voltage capability allows deployment in both standard 3.3 V/5 V systems and battery-powered devices with wide input ranges.
Does the R5F21357CDFP#10 support background operation (BGO) for data flash programming?
Yes, the R5F21357CDFP#10 includes background operation (BGO) functionality for its 4 KB data flash (1 KB × 4 blocks). This permits simultaneous code execution and flash erase/write operations-critical for field firmware updates without interrupting real-time control tasks.
How many analog-to-digital converter (ADC) channels does the R5F21357CDFP#10 provide, and what is their resolution?
The R5F21357CDFP#10 integrates a 10-bit successive-approximation ADC with 12 input channels (AN0–AN11), supporting sample-and-hold and hardware-triggered sweep mode. This enables synchronized multi-sensor acquisition for motor current sensing, temperature monitoring, or audio level detection.
What communication interfaces are built into the R5F21357CDFP#10?
The R5F21357CDFP#10 features UART0 and UART1 (clock-synchronous serial I/O), UART2 with I²C-bus mode and multiprocessor support, SSU (shared with I²C), dedicated I²C bus, and hardware LIN module (using Timer RA and UART0). No CAN or USB interfaces are included.
Is the R5F21357CDFP#10 pin-compatible with other members of the R8C/35C Group?
Yes, all R8C/35C Group MCUs-including R5F21357CDFP#10-share the identical 52-pin LQFP (PLQP0052JA-A) package and pin assignment. Memory size, temperature grade, and minor peripheral enablement differ by part number, but PCB layout and I/O routing remain fully compatible across the family.
