FAQ
What is the operating temperature range for the R5F100GGAFB#X0?
The R5F100GGAFB#X0 is rated for industrial operation from -40°C to +105°C, confirmed by Renesas' G-grade qualification. This makes it suitable for under-hood automotive modules, outdoor utility meters, and factory-floor controllers where ambient heat exceeds consumer-grade limits. The RTC and LVD remain fully functional across this full range.
Does the R5F100GGAFB#X0 include an integrated temperature sensor?
Yes, the R5F100GGAFB#X0 includes an on-chip temperature sensor usable with the 10-bit ADC. It is selectable only in HS (high-speed main) mode per the datasheet and provides calibrated readings referenced to the internal 1.45 V bandgap - enabling thermal compensation in motor drives, power supplies, and environmental monitors without external components.
How many UART/LIN channels does the R5F100GGAFB#X0 support?
The R5F100GGAFB#X0 supports up to four UART/LIN channels. Pin assignments vary by package; for the 48-pin LFQFP, UART0 (P30/P31), UART1 (P12/P13), and UART2 (P40/P41) are available - all with full LIN 2.2 protocol support including automatic sync-break detection and checksum generation required for automotive body networks.
Can the R5F100GGAFB#X0 execute code while rewriting data flash?
Yes, the R5F100GGAFB#X0 supports Background Operation (BGO) for data flash. When enabled, the CPU can fetch and execute instructions from code flash while simultaneously erasing or programming data flash sectors - enabling uninterrupted real-time tasks such as sensor sampling or motor control during firmware parameter updates or event logging.
What is the minimum supply voltage for the R5F100GGAFB#X0?
The R5F100GGAFB#X0 operates down to 1.6 V across its full temperature range, verified in the datasheet's electrical characteristics table. This enables direct use with single-cell LiFePO₄ (2.5–3.65 V) or two-cell alkaline (2.0–3.2 V) batteries, and supports brown-out detection (LVD) at 14 selectable thresholds to ensure safe reset behavior during voltage sag.
