FAQ
What is the maximum operating frequency and supply voltage range for R5F21367CDFP#V0?
The R5F21367CDFP#V0 operates at up to 20 MHz when supplied with 2.7–5.5 V, achieving a minimum instruction execution time of 50 ns. At lower frequencies (e.g., 5 MHz), it supports down to 1.8 V, enabling ultra-low-power operation in battery-backed subsystems while maintaining full peripheral functionality.
Does R5F21367CDFP#V0 support in-circuit debugging and flash programming?
Yes, R5F21367CDFP#V0 includes on-chip debug capability and on-board flash rewrite function. It supports standard Renesas E8/E8a debug interfaces, enabling full breakpoint control, register inspection, and live memory modification during development - no external emulator is required for basic firmware bring-up.
How many A/D converter channels does R5F21367CDFP#V0 have, and what is their resolution?
The R5F21367CDFP#V0 integrates a 10-bit successive-approximation A/D converter with 12 input channels (AN0–AN11). It includes sample-and-hold circuitry and supports automatic channel sweep mode, allowing continuous acquisition across all channels with programmable timing and interrupt-on-conversion completion.
What LIN protocol versions are supported by the hardware LIN module in R5F21367CDFP#V0?
The hardware LIN module in R5F21367CDFP#V0 implements LIN 2.0 and LIN 2.1 specifications using UART0 and TimerRA resources. It handles break field detection, sync field generation, checksum calculation (classic and enhanced), and automatic response timing - compliant with SAE J2602 and ISO 17987-4 standards for automotive and appliance networks.
Is background operation (BGO) available for both program ROM and data flash in R5F21367CDFP#V0?
Background operation (BGO) is supported exclusively for the 4 KB data flash (1 KB × 4 blocks) in R5F21367CDFP#V0. Program ROM erasure and programming require CPU halt; however, data flash operations can execute concurrently with application code, enabling seamless firmware patching and parameter updates without system interruption.
