FAQ
What is the maximum operating frequency and supply voltage range for the R5F21364CNFA#50?
The R5F21364CNFA#50 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 flexible power management in battery-backed or energy-efficient designs. The R5F21364CNFA#50 maintains full peripheral functionality across this entire voltage range.
Does the R5F21364CNFA#50 support hardware LIN communication, and how is it implemented?
Yes, the R5F21364CNFA#50 integrates a hardware LIN module compliant with LIN 2.0/2.1 standards, implemented using Timer RA for signal timing and UART0 for serial framing. This eliminates the need for an external LIN transceiver in node-level applications. The R5F21364CNFA#50 handles break field detection, sync field, and checksum calculation autonomously.
What are the data flash capabilities of the R5F21364CNFA#50, and does it support background operation?
The R5F21364CNFA#50 includes 4 × 1 KB data flash blocks (total 4 KB) with 10,000 write/erase endurance cycles and full background operation (BGO) support. This allows the R5F21364CNFA#50 to execute application code from program ROM while simultaneously reprogramming data flash - essential for logging runtime parameters or updating calibration tables without system interruption.
How many analog input channels and D/A outputs does the R5F21364CNFA#50 provide?
The R5F21364CNFA#50 features a 10-bit A/D converter with 12 analog input channels (AN0–AN11) and two independent 8-bit D/A converters (DA0 and DA1). These are mapped to P0_0–P0_7 pins and support simultaneous sampling with built-in sample-and-hold - enabling the R5F21364CNFA#50 to serve as both sensor interface and analog actuator driver in closed-loop systems.
What low-power modes are available on the R5F21364CNFA#50, and what are their typical current draws?
The R5F21364CNFA#50 supports wait mode (4.0 µA at 3.0 V, 32 kHz XCIN clock active) and stop mode (2.0 µA at 3.0 V, all clocks halted except optional low-speed oscillator). Both modes retain RAM content and allow wake-up via external interrupt, key input, or timer event - making the R5F21364CNFA#50 suitable for battery-powered remote controls or always-on appliance subsystems.
