Product details
Overview
R5F100LHAFA#30 from Renesas is a 64-pin LQFP-0.65mm 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, 12 KB RAM, and integrated RTC, 10-bit ADC (26 channels), UART, I²C, and SPI interfaces - deployed in industrial motor control, sensor nodes, and smart metering systems requiring ultra-low power operation down to 0.57 μA in RTC+LVD mode.
For engineers reviewing the R5F100LHAFA#30 datasheet, R5F100LHAFA#30 pinout, R5F100LHAFA#30 application, or R5F100LHAFA#30 equivalent, key selection criteria include its 64-pin LQFP package, -40°C to +85°C industrial temperature grade (D), 1.6–5.5 V supply range, 32 MHz max CPU speed, and on-chip debug support for rapid firmware validation.
Technical Context
The R5F100LHAFA#30 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 dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 16× 16-bit timers, 1× real-time clock with calendar/alarm/correction, 1× 12-bit interval timer, 2–4 DMA channels, and serial interfaces (CSI/SPI, UART/LIN, I²C) - all configurable via register-based control without external glue logic.

Does the R5F100LHAFA#30 support in-system programming via its serial interfaces?
Yes, the R5F100LHAFA#30 supports in-system programming using the on-chip UART bootloader. Firmware updates can be performed over UART without external debug hardware, leveraging the built-in flash self-programming engine and flash shield window for secure code protection.
How many ADC channels does the R5F100LHAFA#30 provide, and what is their resolution?
The R5F100LHAFA#30 features a 10-bit successive-approximation ADC with up to 26 analog input channels. It includes an internal 1.45 V reference and temperature sensor, and supports simultaneous sampling on multiple channels via hardware trigger sources such as timers or external events.
Is the R5F100LHAFA#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 64-pin LQFP-0.65mm package (e.g., R5F100LCAFA#30 through R5F100LLAFA#30) share identical pinouts and electrical characteristics - enabling drop-in replacement across memory/configurations without PCB redesign.
What debug interface does the R5F100LHAFA#30 use, and is external hardware required?
The R5F100LHAFA#30 uses Renesas' on-chip debug functionality accessible via the FINE interface (single-pin SWD-like protocol).
