FAQ

What is the maximum operating frequency of the R5F100LLAFB#X0?

The R5F100LLAFB#X0 operates up to 32 MHz using its high-accuracy on-chip oscillator (±1.0% over VDD = 1.8–5.5 V and TA = –20 to +85°C). This frequency enables 41 DMIPS performance while maintaining ultra-low power consumption (66 μA/MHz), making it ideal for real-time control tasks in energy-constrained systems.

Does the R5F100LLAFB#X0 support in-system programming via standard interfaces?

Yes, the R5F100LLAFB#X0 supports in-system programming via its on-chip debug interface (using SWD or JTAG), and includes self-programming capability for both code and data flash memory. The flash shield window function and block-erase prohibition provide security against unauthorized reprogramming, ensuring firmware integrity in deployed R5F100LLAFB#X0 units.

How many serial communication interfaces does the R5F100LLAFB#X0 integrate?

The R5F100LLAFB#X0 integrates up to 10 serial interfaces: 2–4 UART/LIN channels, 3–10 I²C/Simplified I²C channels, and 2–8 CSI (SPI-compatible) channels. Pin multiplexing allows dynamic allocation based on application needs - for example, configuring P10/P11 as SCK00/SDA00 for I²C sensor networks or as SCK00/SI00 for SPI flash memory access.

Is the R5F100LLAFB#X0 pin-compatible with other RL78/G13 variants in the same package?

Yes, the R5F100LLAFB#X0 is pin-compatible with all other 64-pin LFQFP RL78/G13 variants sharing the FB suffix (e.g., R5F100LKAFB#X0, R5F100LJAFB#X0), as confirmed by Renesas' standardized pin configuration for the 64-pin LQFP/LFQFP family. This allows drop-in replacement for memory-size or feature-tier upgrades without PCB redesign.
