FAQ
What is the maximum operating frequency and corresponding supply voltage range for the R5F21364CDFA#V0?
The R5F21364CDFA#V0 operates at up to 20 MHz when supplied with 2.7 V to 5.5 V. At lower 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 design flexibility across battery-powered and line-powered systems while maintaining full peripheral functionality in both modes.
Does the R5F21364CDFA#V0 support in-circuit debugging and flash programming after soldering?
Yes, the R5F21364CDFA#V0 includes on-chip debug capability and supports on-board flash rewrite via dedicated debug interface pins. This enables full firmware development, verification, and field updates without requiring external programming hardware, reducing production test complexity and supporting post-deployment maintenance for the R5F21364CDFA#V0.
How does the background operation (BGO) function work in the R5F21364CDFA#V0 data flash?
The R5F21364CDFA#V0 data flash supports background operation (BGO), allowing the CPU to execute code from program ROM or RAM while simultaneously erasing or programming data flash blocks. This eliminates execution stalls during non-volatile parameter updates, enabling seamless runtime configuration changes-critical for applications like calibration storage or firmware patching in the R5F21364CDFA#V0.
What peripheral resources are dedicated to LIN bus communication on the R5F21364CDFA#V0?
The R5F21364CDFA#V0 implements hardware LIN using Timer RA for baud rate generation and pulse timing, combined with UART0 for data framing and error checking. This offloads LIN protocol handling from the CPU, ensuring deterministic timing and freeing processing bandwidth-unlike software-based implementations that consume significant cycles and introduce jitter in the R5F21364CDFA#V0.
Can the R5F21364CDFA#V0 operate from a 32 kHz crystal alone, and what functions remain active in low-power modes?
Yes, the R5F21364CDFA#V0 can run exclusively from the 32 kHz XCIN/XCOUT crystal in wait and stop modes. In stop mode (2.0 µA), only the real-time clock (Timer RE), oscillation stop detection, and voltage monitor remain active; in wait mode (4.0 µA), the CPU halts but peripherals including UART, timers, and ADC retain clocking and can wake the device via interrupt-enabling responsive low-power sensing in the R5F21364CDFA#V0.
