FAQ
What is the operating temperature range for the R5F100GKDFB#30?
The R5F100GKDFB#30 is rated for industrial operation from −40°C to +105°C (G-grade), making it suitable for deployment in harsh environments such as motor drives, outdoor utility meters, and factory-floor controllers where ambient temperatures exceed standard commercial limits. This rating is confirmed in the RL78/G13 datasheet Rev.3.80, Section 1.1.
Does the R5F100GKDFB#30 include data flash memory?
Yes, the R5F100GKDFB#30 includes 8 KB of on-chip data flash memory with background operation (BGO) capability, allowing program execution while rewriting. This enables secure firmware updates and nonvolatile parameter storage without interrupting real-time tasks - a key differentiator from the R5F101GKDFB#30 variant which omits data flash entirely.
What package type and pin count does the R5F100GKDFB#30 use?
The R5F100GKDFB#30 uses a 48-pin LFQFP package with 7 mm × 7 mm footprint and 0.5 mm lead pitch, as specified in Renesas' ordering part number decoding guide (FB = LFQFP, 0.50-mm pitch). This package is compatible with standard surface-mount assembly processes and provides adequate I/O density for mid-complexity industrial control applications.
Can the R5F100GKDFB#30 operate from a single 1.8 V supply?
Yes, the R5F100GKDFB#30 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supply. At 1.8 V, it maintains full functionality including 32 MHz operation (with reduced maximum frequency per datasheet derating curves), ADC conversion, and RTC operation - enabling direct integration with low-voltage battery systems and mixed-signal SoCs.
How many UART/LIN interfaces does the R5F100GKDFB#30 support?
The R5F100GKDFB#30 supports up to two UART channels with LIN-bus protocol compliance, including hardware-level break detection, sync field generation, and checksum calculation. These are implemented on dedicated pins (e.g., P11/RxD0, P12/TxD0) and can operate independently - essential for automotive body electronics and industrial telemetry where dual serial buses are required.
