Product details
Overview
R5F100LFGFA#10 from Renesas is a 64-pin LQFP-0.65mm MCU in the RL78/G13 family, featuring 128 KB flash, 8 KB data flash, 12 KB RAM, 32 MHz operation (41 DMIPS), and ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and real-time clock - deployed in industrial sensor nodes and battery-powered control systems.
For engineers reviewing the R5F100LFGFA#10 datasheet, R5F100LFGFA#10 pinout, R5F100LFGFA#10 application, or R5F100LFGFA#10 equivalent, key selection criteria include its 64-pin LQFP package, -40°C to +105°C industrial temperature grade (G suffix), integrated data flash with 1M-cycle endurance, and support for background operation during flash rewriting.
Technical Context
The R5F100LFGFA#10 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It supports multiple low-power states - HALT, STOP, and SNOOZE - coordinated with on-chip LVD and POR circuits for robust system-level power management.
Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, calendar-based RTC with alarm and correction, and dual-channel DMA supporting 8/16-bit transfers between SFR and RAM in just two clocks - optimized for deterministic real-time response in embedded control loops.

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 RL78/G13 core, identical 128 KB flash/8 KB data flash/12 KB RAM, but in 64-pin LFQFP (0.5 mm pitch) | Requires PCB redesign due to different footprint and pitch; no change in software or peripheral use | Select when migrating to finer-pitch assembly or higher-density layouts |
| R5F101LGAFB#V0 | Same package and pinout, but lacks data flash (0 KB); retains 128 KB code flash and 12 KB RAM | Not suitable for applications requiring nonvolatile parameter storage or firmware logging; reduces BOM cost where data retention is unnecessary | Choose when data flash functionality is unused and cost optimization is prioritized |
Compared with R5F100LFGFA#10, R5F100LGAFB#V0 offers identical functionality in a smaller-footprint LFQFP package, while R5F101LGAFB#V0 removes data flash to lower unit cost - making the original part optimal for applications needing field-updatable configuration and long-term event logging.

What is the operating temperature range for R5F100LFGFA#10?
The R5F100LFGFA#10 is rated for industrial operation from -40°C to +105°C, indicated by the 'G' suffix in its part number. This makes it suitable for deployment in harsh environments such as factory automation controllers, outdoor energy infrastructure, and high-temperature appliance compartments where thermal stability is critical. The device maintains full specification compliance across this entire range.
Does R5F100LFGFA#10 support in-system programming without external hardware?
Yes, R5F100LFGFA#10 supports on-chip debug and self-programming via its built-in bootloader, enabling firmware updates through UART or other serial interfaces without requiring an external programmer. It also features boot swap functionality and flash shield window protection - allowing secure, field-deployable updates while preventing unauthorized access to protected code sections.
How many ADC channels does R5F100LFGFA#10 provide, and what is their resolution?
R5F100LFGFA#10 integrates a 10-bit successive approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference voltage and a calibrated temperature sensor - both accessible via dedicated ANI pins. The ADC supports programmable sample-and-hold timing and can operate concurrently with CPU execution in most low-power modes.
Can R5F100LFGFA#10 execute code while rewriting data flash memory?
Yes, R5F100LFGFA#10 supports background operation (BGO), allowing full program execution from code flash while simultaneously rewriting data flash memory. This capability is essential for applications like data logging or parameter tuning that require uninterrupted real-time processing - eliminating latency or task suspension during nonvolatile storage updates.
What packaging and lead finish does R5F100LFGFA#10 use?
R5F100LFGFA#10 uses a 64-pin LQFP package (12 × 12 mm, 0.65-mm pitch) with lead-free, RoHS-compliant matte tin plating. The '#10' suffix denotes embossed tape packaging per JEDEC standard J-STD-020, suitable for automated SMT placement. Its moisture sensitivity level (MSL) is 3, requiring bake conditioning if exposed beyond floor life limits.
