Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGAFB#V0 | Identical silicon, but supplied in tray packaging (LFQFP, 0.5 mm pitch) instead of embossed tape (#X0) | No functional difference; selected when manual placement or small-batch prototyping is required | Choose #V0 for engineering samples or low-volume production where tape-and-reel feeders are unavailable |
| R5F101LGAFB#X0 | Omits 8 KB data flash; retains same 128 KB code flash, 12 KB RAM, peripherals, and package | Not suitable for applications requiring nonvolatile parameter storage or field-upgradable calibration data | Select only if BGO logging, flash shield window, or boot swap functionality is unnecessary - reduces cost by ~8% |
Compared with R5F100LGAFB#X0, the #V0 variant offers identical electrical and functional performance with different logistics packaging, while R5F101LGAFB#X0 removes data flash capability - making it viable only for fixed-parameter control tasks where runtime data persistence is not required.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LGAFB#X0?
The R5F100LGAFB#X0 operates at up to 32 MHz using its high-speed on-chip oscillator (±1.0% accuracy), delivering 41 DMIPS. Its RL78 CPU core supports variable instruction execution time - from 0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz - enabling dynamic power/performance scaling in the R5F100LGAFB#X0.
Does the R5F100LGAFB#X0 include an integrated temperature sensor, and what is its accuracy?
Yes, the R5F100LGAFB#X0 integrates a factory-calibrated temperature sensor usable in HS (high-speed main) mode. It provides analog output referenced to the internal 1.45 V bandgap, achieving ±2°C accuracy across the full −40°C to +105°C industrial operating range without external components.
How does the R5F100LGAFB#X0 support secure firmware updates?
The R5F100LGAFB#X0 supports secure firmware updates via on-chip self-programming with boot swap function and flash shield window. These features allow authenticated code updates and protected parameter storage within the 128 KB code flash, preventing unauthorized modification - a core capability of the R5F100LGAFB#X0.
What low-power modes are available on the R5F100LGAFB#X0, and what is the lowest achievable current?
The R5F100LGAFB#X0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA - enabling decade-long battery life in intermittent-sampling applications. This ultra-low quiescent current is a defining characteristic of the R5F100LGAFB#X0's power architecture.
Is the R5F100LGAFB#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes - all RL78/G13 devices in the 64-pin LFQFP-0.5mm package (e.g., R5F100LGAFB#X0, R5F101LGAFB#X0, R5F100LHAFB#X0) share identical pinouts and electrical characteristics. This allows hardware reuse across memory/configurations, provided software accounts for differences in flash size, data flash presence, and peripheral enablement in the R5F100LGAFB#X0.
