Product details
Overview
R5F100LHDFA#V0 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 (0.57 μA RTC+LVD). It integrates 16-bit timers, 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and operates from 1.6–5.5 V for industrial control and sensor node applications.
For engineers reviewing the R5F100LHDFA#V0 datasheet, R5F100LHDFA#V0 pinout, R5F100LHDFA#V0 application, or R5F100LHDFA#V0 equivalent, key selection criteria include its 64-pin LQFP package, industrial-grade -40°C to +85°C rating (D-grade), integrated data flash with background operation, and RL78 CPU core with 3-stage pipeline and sub-μA sleep capability.
Technical Context
The R5F100LHDFA#V0 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It supports multiple low-power states-HALT, STOP, and SNOOZE-with dedicated oscillators including a ±1.0% accurate 32 MHz on-chip high-speed oscillator and 32.768 kHz subsystem clock.
It embeds a 10-bit A/D converter with up to 26 input channels, internal 1.45 V reference and temperature sensor, real-time clock with calendar/alarm/correction, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.

This qualifies it for use in motor drives, programmable logic controllers, and HVAC systems where ambient conditions exceed consumer-grade limits. The device maintains full functionality-including flash programming, ADC accuracy, and oscillator stability-across this full range without derating.
Does the R5F100LHDFA#V0 include data flash memory, and what is its endurance?
Yes, the R5F100LHDFA#V0 includes 8 KB of on-chip data flash memory, specified for 1,000,000 write/erase cycles (typical) at VDD = 1.8–5.5 V. It supports background operation (BGO), enabling code execution from program memory during data flash rewrites-a key capability for logging sensor data or storing calibration parameters without interrupting real-time tasks in the R5F100LHDFA#V0.
What package type and pin count does the R5F100LHDFA#V0 use?
The R5F100LHDFA#V0 uses a 64-pin LQFP package with 0.65-mm pitch (RENESAS code PLQP0064JA-A), supplied in trays (#V0). Its pinout is fully compatible with other RL78/G13 64-pin variants in the same package family, including R5F100LCDFA#V0 and R5F100LCGFA#V0, enabling design reuse across memory and feature variants within the same footprint.
Can the R5F100LHDFA#V0 operate from a single 1.8 V supply?
Yes, the R5F100LHDFA#V0 supports operation from 1.6 V to 5.5 V, including 1.8 V nominal supply. At 1.8 V, it achieves up to 16 MHz maximum frequency (per datasheet Section 1.1), with full peripheral functionality-including 10-bit ADC, UART, and timers-maintained. The on-chip voltage detector (LVD) provides selectable reset thresholds down to 1.6 V, ensuring safe brown-out recovery in the R5F100LHDFA#V0.
How many serial communication interfaces does the R5F100LHDFA#V0 support?
The R5F100LHDFA#V0 supports up to 3 I²C/Simplified I²C channels, 2–4 UART/LIN channels, and 2–8 CSI (SPI-compatible) channels-configurable per pin mapping and memory variant. For the R5F100LHDFA#V0 specifically (64-pin, D-grade), all 3 I²C, 4 UART, and 8 CSI channels are available, enabling concurrent communication with displays, sensors, transceivers, and host processors without external bridging.
