Product details
Overview
R5F100LGAFA#V0 from Renesas is a 64-pin LQFP-0.65mm, 128 KB flash, 8 KB data flash, 12 KB RAM RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz), real-time clock, 10-bit ADC (26 channels), and integrated UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100LGAFA#V0 datasheet, R5F100LGAFA#V0 pinout, R5F100LGAFA#V0 application, or R5F100LGAFA#V0 equivalent, key selection criteria include its 64-pin LQFP package, -40°C to +85°C industrial-grade temperature range (A-grade), 128 KB code flash with self-programming, RTC calendar function, and HALT/STOP/SNOOZE low-power modes for energy-constrained embedded control.
Technical Context
The R5F100LGAFA#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a 12-bit interval timer, dedicated RTC with calendar/alarm/correction, and watchdog timer driven by a separate low-speed on-chip oscillator.
Its peripheral set includes up to 16× 16-bit timers, 3–10-channel I²C/Simplified I²C, 2–4-channel UART/LIN, 2–8-channel CSI, 8–26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, and DMA controller with 2/4 channels supporting background data flash rewriting during program execution.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables deterministic timing and compact code footprint for resource-limited control applications. |
| Operating Voltage | 1.6 V to 5.5 V single supply; supports direct interface with 1.8 V, 2.5 V, and 3.3 V peripherals without level shifters. |
| Flash Memory | 128 KB code flash with 1 KB block size and security lock; allows secure firmware updates and boot swap functionality. |
| Data Flash | 8 KB data flash with background operation (BGO); enables logging or parameter storage while executing application code. |
| RAM | 12 KB on-chip RAM; sufficient for real-time control stacks, communication buffers, and RTC-backed data retention. |
| Power Consumption | 66 μA/MHz active; 0.57 μA in STOP mode with RTC + LVD active; critical for multi-year battery life in remote sensing nodes. |
| ADC | 10-bit resolution, 26 analog inputs, internal 1.45 V reference, and integrated temperature sensor; eliminates external references for environmental monitoring. |
Pinout & Package
Package: 64-pin LQFP (12 × 12 mm, 0.65-mm pitch), RoHS-compliant, JEDEC-standard footprint compatible with automated SMT assembly.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGAFB#V0 | Same core, memory, and peripherals but in 64-pin LFQFP (0.5-mm pitch); smaller footprint, higher density layout. | Preferred where board space is constrained and fine-pitch reflow capability exists. | Select when PCB real estate is limited and assembly process supports 0.5-mm pitch; not drop-in compatible due to different land pattern. |
| R5F101LGAFA#V0 | Identical package and pinout but lacks data flash (0 KB); retains 128 KB code flash and same low-power features. | Suitable for cost-sensitive applications where parameter storage is handled externally or via EEPROM. | Choose when data logging or field-updatable configuration is unnecessary; reduces BOM cost while preserving software compatibility. |
Compared with R5F100LGAFA#V0, R5F100LGAFB#V0 offers identical functionality in a denser package requiring tighter layout tolerances, while R5F101LGAFA#V0 removes data flash to lower unit cost - both retain full code flash, RTC, and ultra-low-power modes for seamless migration in non-data-logging variants.

Does R5F100LGAFA#V0 support in-system programming via UART?
Yes, R5F100LGAFA#V0 supports in-system programming (ISP) via UART using Renesas' standard flash programming protocol. The device includes an on-chip debug interface and boot swap functionality, enabling secure firmware updates without removing the MCU from the board - a key requirement for field-deployed R5F100LGAFA#V0 applications.
How many I²C channels does R5F100LGAFA#V0 provide?
R5F100LGAFA#V0 provides up to 10 hardware I²C/Simplified I²C channels, configurable across multiple pins. Channel count depends on pin assignment and peripheral multiplexing; the full 10-channel capability is accessible in the 64-pin LQFP package when using dedicated I²C pins - enabling daisy-chained sensor networks in R5F100LGAFA#V0-based designs.
Can R5F100LGAFA#V0 operate from a single 1.8 V supply?
Yes, R5F100LGAFA#V0 operates across 1.6 V to 5.5 V, fully functional at 1.8 V. At this voltage, maximum clock frequency is reduced to 16 MHz (per datasheet DC characteristics), but all peripherals - including 10-bit ADC, RTC, and UART - remain operational, supporting ultra-low-voltage battery systems in R5F100LGAFA#V0 implementations.
Is there a hardware multiplier unit in R5F100LGAFA#V0?
Yes, R5F100LGAFA#V0 includes a dedicated 16-bit × 16-bit hardware multiplier and 32-bit ÷ 32-bit divider, plus a multiply-accumulate (MAC) unit supporting 16-bit × 16-bit + 32-bit operations.
