FAQ
What is the maximum LCD segment count supported by the R5F10WMFAFA#30?
The R5F10WMFAFA#30 supports up to 51 segment outputs and 8 common outputs, enabling alphanumeric + icon displays such as 4-digit numeric plus status indicators. This configuration is confirmed in the RL78/L13 datasheet Section 1.6 and applies specifically to the 80-pin variants like the R5F10WMFAFA#30.
Does the R5F10WMFAFA#30 support background data flash rewriting during program execution?
Yes, the R5F10WMFAFA#30 supports Background Operation (BGO) for its 4 KB data flash memory. Instructions can be executed from code flash while simultaneously rewriting data flash - a capability documented in Section 1.1 of the datasheet and essential for seamless firmware updates and data logging.
What are the valid operating voltage and temperature ranges for the R5F10WMFAFA#30?
The R5F10WMFAFA#30 operates across VDD = 1.6 V to 5.5 V and ambient temperature TA = −40°C to +85°C, as specified for consumer-grade A-variant parts. These ratings are explicitly defined in Section 1.1 and Electrical Specifications (Page 17) of the R01DS0168EJ0232 datasheet.
How many UART channels does the R5F10WMFAFA#30 include, and which support LIN bus?
The R5F10WMFAFA#30 includes three UART channels: UART0, UART1, and UART3. Only UART0 supports LIN bus protocol per the datasheet's Serial Interface section (Page 16), with dedicated LINSEL pin functionality confirmed in the 80-pin block diagram (Page 14).
Is the R5F10WMFAFA#30 pin-compatible with other RL78/L13 80-pin variants like R5F10WMEAFA#30?
No - while both use 80-pin LQFP packages, the R5F10WMFAFA#30 and R5F10WMEAFA#30 differ in flash/RAM size and peripheral enablement; however, they share identical pinouts and electrical characteristics per Renesas' RL78/L13 family documentation, enabling PCB reuse across memory variants.
