FAQ
What is the flash memory configuration of the R5F101LKDFA#30?
The R5F101LKDFA#30 contains 128 KB of code flash memory and no data flash memory. This is confirmed by the "101" in the part number (per Renesas documentation: "100" = data flash included; "101" = data flash omitted). The device supports self-programming with boot swap and flash shield window functions for secure firmware updates.
Does the R5F101LKDFA#30 support real-time clock functionality?
Yes, the R5F101LKDFA#30 integrates a full-featured real-time clock (RTC) with calendar support (99-year range), alarm function, and clock correction. It operates in STOP mode at 0.57 μA when powered by VDD, enabling accurate timekeeping during ultra-low-power states - critical for timestamped sensor logging and scheduled wake-up events.
What is the operating temperature range for the R5F101LKDFA#30?
The R5F101LKDFA#30 is rated for industrial operation from -40°C to +85°C (grade "D", per Renesas part numbering convention). This is distinct from consumer-grade "A" (-40°C to +85°C, non-industrial qualification) and extended industrial "G" (-40°C to +105°C) variants - ensuring reliability in factory automation, building controls, and outdoor equipment.
Which package type does the R5F101LKDFA#30 use?
The R5F101LKDFA#30 uses a 64-pin LQFP package with 12 × 12 mm body size and 0.65 mm lead pitch (Renesas code PLQP0064JA-A). It is distinct from the LFQFP-64 variant (e.g., R5F101LKDFB#30) which uses 10 × 10 mm and 0.5 mm pitch - requiring separate PCB layout and assembly validation.
Can the R5F101LKDFA#30 operate from a 1.8 V supply?
Yes, the R5F101LKDFA#30 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supply. Its I/O structure supports different-potential interfacing, allowing direct connection to 1.8 V logic without level shifters - verified in the "I/O port" section of the datasheet, which specifies TTL input buffer and 1.8/2.5/3 V interface capability.
