FAQ
What is the operating temperature range for R5F101GKDFB#10?
The R5F101GKDFB#10 is rated for industrial operation from −40°C to +105°C, as indicated by the 'G' suffix in its part number per Renesas' RL78/G13 ordering guide. This makes it suitable for under-hood automotive modules, factory-floor controllers, and outdoor metering equipment where extended thermal resilience is required.
Does R5F101GKDFB#10 include data flash memory?
Yes, the R5F101GKDFB#10 includes 8 KB of on-chip data flash memory with 1,000,000 write/erase cycles (typical), supporting background operation (BGO) so program execution continues during data logging or firmware parameter updates - a key capability confirmed in the RL78/G13 datasheet Section 1.1.
How many ADC channels does R5F101GKDFB#10 support?
The R5F101GKDFB#10 supports up to 26 analog input channels for its 10-bit successive-approximation ADC, with dedicated AVREFP/AVREFM pins and an internal 1.45 V reference voltage. Channel count is fixed per device variant and verified in the RL78/G13 datasheet Table 1-1 and Section 1.1 "A/D converter".
Is R5F101GKDFB#10 pin-compatible with other RL78/G13 48-pin variants?
Yes - all RL78/G13 48-pin LFQFP variants (e.g., R5F101GKAFB#V0, R5F101GLDFB#10) share identical pinouts and electrical characteristics per the RL78/G13 datasheet Section 1.3 Pin Configuration. This allows direct PCB reuse across memory and feature variants within the same package footprint.
What debug interface does R5F101GKDFB#10 use?
The R5F101GKDFB#10 uses the standard Renesas E20 on-chip debug interface, accessible via a 6-pin SWD/JTAG connector. It supports full real-time debugging, flash programming, and trace without requiring external debug hardware - confirmed in the RL78/G13 datasheet Section 1.1 "On-chip debug function".
