Product details
Overview
R5F100LGAFA#50 from Renesas is a 16-bit RL78/G13 microcontroller with 128 KB flash memory, 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), integrated 10-bit ADC (26 channels), real-time clock, and multiple serial interfaces (UART, I²C, CSI) for embedded control in industrial and consumer applications.
For engineers reviewing the R5F100LGAFA#50 datasheet, R5F100LGAFA#50 pinout, R5F100LGAFA#50 application, or R5F100LGAFA#50 equivalent, key selection criteria include its LQFP-64 (0.65 mm pitch) package, -40°C to +85°C industrial temperature grade (A-grade), on-chip debug support, self-programming flash capability, and hardware multiplier/divider for deterministic control-loop execution.
Technical Context
The R5F100LGAFA#50 implements the RL78 CPU core with a 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 low-power mode). It integrates dual-clock domains: a high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable) and a dedicated low-speed oscillator for watchdog and RTC operation.
Its peripheral set includes 16× 16-bit timers, 1× 12-bit interval timer, 1× calendar RTC with alarm and correction, 2–4 channel DMA, and 3–10 channel I²C/Simplified I²C - all mapped to a 64-pin LQFP footprint with configurable I/O (up to 52 general-purpose pins, including N-ch open-drain and TTL-compatible inputs).

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LGAFA#50?
The R5F100LGAFA#50 operates at up to 32 MHz using its high-accuracy on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs in high-speed mode, enabling deterministic real-time control loops and fast peripheral response in applications like motor control and sensor fusion.
Does the R5F100LGAFA#50 support in-system programming and secure firmware updates?
Yes, the R5F100LGAFA#50 supports full on-chip debug via single-wire interface and includes self-programming capabilities with boot-swap functionality and flash shield window protection. These features allow secure field firmware updates without external programmers and prevent unauthorized access to code memory during reprogramming.
What analog features are integrated into the R5F100LGAFA#50 for sensor interfacing?
The R5F100LGAFA#50 integrates a 10-bit successive-approximation ADC with up to 26 input channels, internal 1.45 V reference voltage, and an on-chip temperature sensor.

How does the R5F100LGAFA#50 achieve ultra-low power consumption in battery-operated applications?
The R5F100LGAFA#50 achieves ultra-low power through multiple low-power modes: HALT (0.73 μA typical), STOP (0.57 μA with RTC + LVD active), and SNOOZE (low-power peripheral operation while CPU sleeps). Its 1.6–5.5 V wide supply range and programmable voltage detector (14 levels) enable reliable operation across declining battery voltages without external supervision circuitry.
Is the R5F100LGAFA#50 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100LGAFA#50 is pin-compatible with all other RL78/G13 devices in the 64-pin LQFP-0.65 mm package (e.g., R5F100LCAFA#50, R5F100LHAFA#50), sharing identical pin functions and electrical characteristics. This allows scalable memory selection (16–128 KB flash) without PCB redesign, provided peripheral usage aligns with the specific variant's feature set.
