FAQ
Does R5F101LLAFB#V0 include on-chip data flash memory?
No, R5F101LLAFB#V0 does not include on-chip data flash memory. The "101" in the part number explicitly denotes absence of data flash (per RL78/G13 datasheet Section 1.2). It provides 512 KB code flash and 32 KB RAM only. For data flash capability, consider R5F100LLAFB#V0 - which shares identical pinout and package but adds 8 KB data flash.
What is the maximum operating frequency and corresponding performance of R5F101LLAFB#V0?
R5F101LLAFB#V0 operates up to 32 MHz using the high-speed on-chip oscillator, achieving 41 DMIPS (Dhrystone 2.1) performance. Its minimum instruction execution time is 0.03125 μs at 32 MHz, and it supports dynamic clock switching down to 32.768 kHz for ultra-low-power RTC operation with 30.5 μs instruction time.
Which package type and footprint does R5F101LLAFB#V0 use?
R5F101LLAFB#V0 uses a 64-pin LFQFP (Low-profile Fine-pitch Quad Flat Package) with 10 mm × 10 mm body size and 0.5 mm lead pitch. The "FB" suffix in the part number confirms LFQFP-0.5 mm, and "#V0" indicates tray packaging. This is distinct from LQFP-0.65 mm ("FA") or VFBGA ("BG") variants in the same family.
What temperature grade is specified for R5F101LLAFB#V0?
R5F101LLAFB#V0 is rated for industrial operation from -40°C to +85°C. The "D" in the full ordering code (e.g., R5F101LLADFB#V0) designates the industrial temperature grade. It is not rated for extended -40°C to +105°C operation (which requires "G" grade variants like R5F101LLAGFB#V0).
Can R5F101LLAFB#V0 support real-time clock functionality with calendar and alarm?
Yes, R5F101LLAFB#V0 integrates a full-featured real-time clock (RTC) module supporting calendar (year/month/day/hour/minute/second), alarm interrupt, periodic interrupt, and automatic clock correction. It operates independently in STOP mode with only RTC and LVD enabled, drawing just 0.57 μA - enabling decade-long timestamped logging in battery-powered applications.
