For engineers reviewing the R5F100LGGFA#V0 datasheet, R5F100LGGFA#V0 pinout, R5F100LGGFA#V0 application, or R5F100LGGFA#V0 equivalent, key selection criteria include its -40°C to +105°C industrial temperature rating, integrated RTC + LVD, 26-channel 10-bit ADC, dual UART/LIN support, and ultra-low 0.57 μA STOP-mode current with RTC active.
Technical Context
The R5F100LGGFA#V0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip debug, self-programming flash with boot swap, and background operation for data flash rewriting.
Power management includes HALT, STOP, and SNOOZE modes; voltage detection (14-level LVD) triggers interrupt or reset; DMA supports 4 channels with 2-clock transfers between SFR and RAM; and the 16×16/32÷32 multiplier-accumulator enables efficient motor control math.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100LGGFA#V0?
The R5F100LGGFA#V0 operates at up to 32 MHz with a measured performance of 41 DMIPS. This benchmark reflects its RL78 CPU core's 3-stage pipeline efficiency and is validated under standard test conditions per Renesas documentation. The R5F100LGGFA#V0 achieves this performance while maintaining ultra-low active current (66 μA/MHz), making it suitable for compute-constrained, power-sensitive applications.
Does the R5F100LGGFA#V0 include an integrated temperature sensor and voltage reference?
Yes, the R5F100LGGFA#V0 integrates a factory-calibrated temperature sensor and a 1.45 V internal reference voltage source. Both are accessible via the ADC module and can be used simultaneously-for example, measuring board temperature while performing ratiometric sensor readings. These features are confirmed in the RL78/G13 datasheet section "A/D converter" and eliminate the need for external analog components in thermal monitoring designs.
What low-power modes does the R5F100LGGFA#V0 support, and what is its lowest current consumption?
The R5F100LGGFA#V0 supports HALT, STOP, and SNOOZE modes. Its lowest operational current is 0.57 μA in STOP mode with only the real-time clock (RTC) and low-voltage detector (LVD) active-verified in the datasheet's electrical characteristics table. This enables multi-year battery life in applications such as wireless sensor nodes and standby controllers where periodic wake-up events are required.
Is the R5F100LGGFA#V0 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-including R5F100LGGFA#V0, R5F100LGGBD#V0, and R5F101LGGBD#V0-share identical pinouts and mechanical footprint. This allows direct substitution within the same package family for memory or grade changes without PCB redesign, provided peripheral usage aligns with the selected variant's feature set.
How much data flash memory does the R5F100LGGFA#V0 provide, and what is its endurance specification?
The R5F100LGGFA#V0 provides 8 KB of on-chip data flash memory, rated for 1,000,000 write/erase cycles (typical) across the full operating voltage range of 1.8–5.5 V. Background operation (BGO) is supported, allowing program execution from code flash during data flash rewrites-a capability confirmed in the RL78/G13 datasheet section "Data Flash Memory."
