The R5F21336CNFP#50 supports a maximum operating frequency of 20 MHz when supplied at VCC = 2.7–5.5 V. At lower voltages (1.8–5.5 V), it operates up to 5 MHz. This dual-frequency capability allows design flexibility across battery-powered and line-powered applications while maintaining full peripheral functionality in both modes.
Does the R5F21336CNFP#50 support in-system programming and background operation of data flash?
Yes, the R5F21336CNFP#50 includes 4 KB of data flash (1 KB × 4 blocks) with full background operation (BGO) support. This allows the CPU to execute application code from program ROM while simultaneously erasing or programming data flash-critical for field firmware updates and parameter storage without system interruption.
How many analog input channels does the R5F21336CNFP#50 ADC support, and what is its resolution?
The R5F21336CNFP#50 integrates a 10-bit successive-approximation A/D converter with 12 analog input channels (AN0–AN11). It includes sample-and-hold functionality and sweep mode for automatic channel scanning-enabling accurate voltage monitoring of multiple sensors or user interface elements in real time.
What peripheral interfaces are available on the R5F21336CNFP#50 for communication with external devices?
The R5F21336CNFP#50 provides UART0, UART1, and UART2 (with I²C-bus mode), a dedicated I²C-bus interface (shared with SSU), synchronous serial unit (SSU), and hardware LIN module (using Timer RA and UART0). These interfaces support multi-protocol connectivity for displays, sensors, transceivers, and legacy automotive networks.
Is the R5F21336CNFP#50 pin-compatible with other members of the R8C/33C Group?
Yes, all R8C/33C Group MCUs-including R5F21331CNFP through R5F21336CNFP and their D-version counterparts-share the identical 32-pin LQFP (PLQP0032GB-A) package and pin assignment.
