Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LGDFB#X0 | No data flash (0 KB); same 128 KB code flash, 12 KB RAM, 64-pin LQFP-G | Lacks nonvolatile parameter storage; unsuitable for field calibration or event logging | Select when firmware-only storage suffices and cost reduction is critical |
| RA2A1GBMFP#AC0 | Arm Cortex-M23 core, 256 KB flash, 32 KB SRAM, 12-bit 24-channel ADC, 48 MHz max | Higher performance, richer peripheral set (USB, CAN), but higher power (120 μA/MHz) | Choose for next-gen designs requiring USB connectivity or enhanced compute headroom |
Compared with R5F100LGDFA#X0, R5F101LGDFB#X0 removes data flash to reduce cost while retaining identical code density and packaging-ideal for fixed-parameter systems; RA2A1GBMFP#AC0 offers Arm ecosystem advantages and USB but trades off ultra-low-power efficiency and legacy toolchain compatibility.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100LGDFA#X0?
The R5F100LGDFA#X0 operates up to 32 MHz using its high-accuracy on-chip oscillator (±1.0 %). At this speed, active-mode current is 66 μA/MHz - meaning ~2.1 mA total at 32 MHz with all peripherals enabled. In STOP mode with only RTC and LVD active, it draws just 0.57 μA, enabling multi-year battery operation in sensor applications.
Does the R5F100LGDFA#X0 support LIN bus communication, and how is it implemented?
Yes, the R5F100LGDFA#X0 supports LIN bus communication via its UART peripherals. UART0 and UART1 each include LIN-break-detection and sync-byte transmission features compliant with LIN 2.2A. The MCU handles LIN frame formatting in firmware, with hardware assist for break detection and checksum calculation - eliminating need for external LIN transceivers in basic implementations.
How much user-accessible RAM is available on the R5F100LGDFA#X0, and is any reserved for system functions?
The R5F100LGDFA#X0 provides 12 KB of on-chip RAM. Of this, 256 bytes starting at address FF300H are reserved for the flash self-programming library during data flash write/erase operations. The remaining 11.75 KB is fully available for application use, including stack, heap, and global variables - verified in the RL78/G13 hardware manual section "RAM Areas Used by Flash Library".
What are the supported clock sources for the R5F100LGDFA#X0, and can it run without an external crystal?
The R5F100LGDFA#X0 supports multiple clock sources: high-speed on-chip oscillator (1–32 MHz, ±1.0 %), subsystem clock (32.768 kHz for RTC), and optional external crystal/resonator on XT1/XT2 pins. It can operate fully without external crystals - the on-chip oscillator enables immediate startup and eliminates BOM cost and layout area for timing components.
Is the R5F100LGDFA#X0 pin-compatible with other RL78/G13 variants in the same 64-pin LQFP package?
Yes, all RL78/G13 devices in the 64-pin LQFP-0.65mm package (e.g., R5F100LCAFA#X0, R5F100LLAFA#X0) share identical pinouts and electrical characteristics. Function allocation (e.g., ADC channel mapping, UART assignment) is consistent across the family - enabling hardware reuse across memory/configurations without PCB redesign.
