Overview
R5F100LGAFB#10 from Renesas is a 16-bit RL78/G13 microcontroller with 128 KB code flash, 8 KB data flash, and 12 KB RAM, operating at up to 32 MHz (41 DMIPS), featuring ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 64-pin LFQFP-0.5 mm package, and integrated peripherals including 10-bit ADC (26 channels), RTC, UART, I²C, and SPI for embedded control in industrial temperature range (–40°C to +105°C).
For engineers reviewing the R5F100LGAFB#10 datasheet, R5F100LGAFB#10 pinout, R5F100LGAFB#10 application, or R5F100LGAFB#10 equivalent, key selection considerations include its industrial-grade thermal rating, on-chip data flash rewrite endurance (1M cycles), background operation capability, real-time clock calendar function, and support for low-voltage operation down to 1.6 V.
Technical Context
The R5F100LGAFB#10 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 subsystem clock). It integrates a 12-bit interval timer, 16-bit timers (12 channels), and a calendar-capable real-time clock with alarm and correction functions.
Power management includes HALT, STOP, and SNOOZE modes; on-chip LVD offers 14 selectable voltage detection levels with interrupt/reset options; DMA controller supports 4 channels with 2-clock transfers between SFR and RAM; and self-programming includes boot swap and flash shield window functions.

The R5F100LGAFB#10 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating is achieved using the high-speed on-chip oscillator calibrated to ±1.0% accuracy across 1.8–5.5 V and –20°C to +85°C, and remains valid under the full industrial temperature range (–40°C to +105°C) per device characterization.
Does the R5F100LGAFB#10 include on-chip data flash memory, and what is its endurance specification?
Yes, the R5F100LGAFB#10 includes 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), allowing code execution from main flash while rewriting data flash - a key capability for R5F100LGAFB#10-based firmware update and calibration storage implementations.
What package type and pin count does the R5F100LGAFB#10 use, and is it RoHS-compliant?
The R5F100LGAFB#10 uses a 64-pin LFQFP package (10 × 10 mm, 0.50-mm pitch) with an exposed thermal pad. It is RoHS-compliant and meets JEDEC standards for moisture sensitivity level (MSL) 3. The #10 suffix denotes embossed tape packaging per Renesas ordering conventions.
How many analog input channels does the R5F100LGAFB#10 support, and what ADC resolution is available?
The R5F100LGAFB#10 supports up to 26 analog input channels with a 10-bit successive-approximation ADC. It includes an internal 1.45 V reference voltage and an integrated temperature sensor - both accessible via dedicated pins (P20/P21 for AVREFP/AVREFM) and usable across the full 1.6–5.5 V supply range.

The R5F100LGAFB#10 supports HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current consumption at VDD = 3.0 V and TA = 25°C - verified per R01DS0131EJ0380 datasheet Section 1.1. This enables decade-long battery operation in always-on sensor and metering applications.
Is the R5F100LGAFB#10 qualified for industrial temperature operation, and what is its specified range?
Yes, the R5F100LGAFB#10 is qualified for industrial temperature operation with a specified ambient operating range of –40°C to +105°C (G-grade). This rating is confirmed in the RL78/G13 datasheet Section 1.1 and applies to all electrical specifications unless otherwise noted in derating tables.
