Product details
Overview
R5F100LHAFA#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, 16-bit RL78 CPU core, and real-time clock with calendar support. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and targets ultra-low-power industrial control and sensor interface applications.
For engineers reviewing the R5F100LHAFA#V0 datasheet, R5F100LHAFA#V0 pinout, R5F100LHAFA#V0 application, or R5F100LHAFA#V0 equivalent, key selection criteria include its 64-pin LQFP package, integrated RTC with alarm/calendar, 10-bit A/D converter (26 channels), low-power STOP/HALT modes (0.57 μA), and LIN-capable UART interfaces for automotive body electronics and smart home controllers.
Technical Context
The R5F100LHAFA#V0 implements the RL78 CISC CPU core with 3-stage pipeline and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, selectable 1–32 MHz) and dedicated low-speed oscillator for RTC/WDT operation.
Its peripheral set includes up to 16 × 16-bit timers, 3 × I²C/Simplified I²C channels, 2 × UART/LIN interfaces, 2 × CSI/SPI channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all accessible within a single 64-pin LQFP footprint supporting mixed-voltage I/O (1.8/2.5/3.0 V compatibility).

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100LGAFA#V0 | Same 64-pin LQFP package, identical peripherals, but 96 KB flash / 8 KB data flash / 8 KB RAM | Suitable for less complex firmware with smaller code footprint and reduced data logging depth | Select when application firmware size is under 96 KB and RAM usage stays below 8 KB - lowers cost without sacrificing pinout or peripheral compatibility |
| R5F100LJAFA#V0 | Same package and memory (128 KB/8 KB/12 KB), but rated for -40°C to +105°C (G-grade) instead of -40°C to +85°C (A-grade) | Required for under-hood automotive or high-temperature industrial enclosures where ambient exceeds 85°C | Choose for extended temperature environments; otherwise, R5F100LHAFA#V0 offers optimal cost/performance for commercial and standard industrial use |
Compared with R5F100LGAFA#V0 and R5F100LJAFA#V0, the R5F100LHAFA#V0 balances full feature set, commercial temperature range, and cost efficiency - making it ideal for high-volume consumer and industrial control designs where 128 KB flash and 12 KB RAM are fully utilized but extended temperature rating is unnecessary.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100LHAFA#V0?
The R5F100LHAFA#V0 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs at this speed, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - enabling both high-throughput control loops and extended battery life in the same design.
Does the R5F100LHAFA#V0 support hardware LIN communication without an external transceiver?
Yes, the R5F100LHAFA#V0 includes dedicated LIN physical layer pins (P50/CLKP and P51/CLKN) that support direct connection to a LIN bus. When paired with an external LIN bus driver (e.g., TLE7259), it achieves full LIN 2.2 compliance - eliminating the need for software bit-banging or additional protocol ICs in automotive body electronics applications.
How does the data flash memory in the R5F100LHAFA#V0 differ from standard code flash in terms of usage and endurance?
The R5F100LHAFA#V0 integrates 8 KB of dedicated data flash memory rated for 1,000,000 write/erase cycles (typical), supporting background operation (BGO) so CPU instructions can execute from code flash while data flash is being rewritten. This enables reliable nonvolatile parameter storage, calibration data logging, and firmware update staging - unlike code flash, which is optimized for program storage and has lower rewrite endurance.
What power-saving modes are available on the R5F100LHAFA#V0, and what is the lowest achievable current draw?
The R5F100LHAFA#V0 offers HALT, STOP, and SNOOZE modes. In STOP mode with only RTC and LVD active, it draws just 0.57 μA (typical) at VDD = 1.8–5.5 V and TA = –40 to +85°C. This ultra-low quiescent current enables decade-long battery operation in metering and remote sensor applications without compromising timekeeping or voltage monitoring functionality.
Can the R5F100LHAFA#V0 interface directly with 1.8 V or 2.5 V logic devices?
Yes, the R5F100LHAFA#V0 supports different-potential interface capability: selected I/O ports can operate with 1.8 V, 2.5 V, or 3.0 V external logic levels while powered from a 1.6–5.5 V VDD rail. This eliminates level-shifters in mixed-voltage systems - such as connecting to low-voltage sensors or FPGAs - and simplifies board design for portable and industrial edge devices.
