FAQ

What is the operating temperature range for the R5F100PKAFB#V0?

The R5F100PKAFB#V0 is rated for industrial operation from -40°C to +105°C (G-grade), validated across its full voltage range (1.6–5.5 V) and all specified clock frequencies. This makes it suitable for under-hood automotive modules, factory-floor controllers, and outdoor sensor enclosures where thermal extremes are expected. The on-chip temperature sensor is calibrated across this entire range.

Does the R5F100PKAFB#V0 support LIN communication natively?

Yes, the R5F100PKAFB#V0 supports LIN communication through UART0, which meets ISO 17987-4 electrical specifications for LIN physical layer operation-enabling transceiverless node implementation. No external LIN transceiver is required for basic slave functionality, reducing BOM count and board area. Protocol stack implementation remains software-defined.

How many ADC channels does the R5F100PKAFB#V0 provide, and what is their resolution?

The R5F100PKAFB#V0 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes internal 1.45 V reference voltage and supports differential input modes. Conversion time is programmable down to 1.2 μs per sample, enabling real-time motor current sampling at 20 kHz switching frequencies.

Can the R5F100PKAFB#V0 execute code while rewriting data flash memory?

Yes, the R5F100PKAFB#V0 supports Background Operation (BGO) for data flash. Code execution continues uninterrupted from program memory during data flash erase/write cycles, eliminating CPU stalls and ensuring deterministic real-time response-critical for safety-critical logging or firmware update scenarios.

What package type and pin count does the R5F100PKAFB#V0 use?

The R5F100PKAFB#V0 uses a 100-pin LFQFP package with 0.5 mm pitch (14 mm × 14 mm body), designated by the "FB" suffix and "#V0" tray packaging code. This package provides robust thermal performance and mechanical stability for industrial reflow processes, with exposed pad option available in compatible variants.
