Product details
Overview
R5F100SHAFB#X0 from Renesas is a 128-pin LFQFP (14 × 20 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 128 KB flash, 8 KB data flash, 12 KB RAM, and operation from −40°C to +85°C (D-grade). It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active and 0.57 μA in RTC+LVD-only mode, and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (26 channels), and real-time clock - deployed in smart metering and industrial sensor nodes.
For engineers reviewing the R5F100SHAFB#X0 datasheet, R5F100SHAFB#X0 pinout, R5F100SHAFB#X0 application, or R5F100SHAFB#X0 equivalent, key selection criteria include its D-grade temperature rating, on-chip data flash rewrite endurance (1M cycles), low-power STOP/HALT modes, and support for LIN-bus via UART - critical for battery-powered industrial control and energy monitoring designs.
Technical Context
The R5F100SHAFB#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, 1 MB address space, and configurable instruction timing (0.03125 μs min @ 32 MHz to 30.5 μs @ 32.768 kHz). It supports background data flash rewriting (BGO) and self-programming with boot swap and flash shield window functions.
Power management includes on-chip POR, 14-level LVD with interrupt/reset options, and three ultra-low-power modes (HALT, STOP, SNOOZE). The peripheral set features up to 26-channel 10-bit ADC with internal 1.45 V reference and temperature sensor, 8–16 channels of 16-bit timer, and 3–10 I²C/Simplified I²C channels - all operating across 1.6–5.5 V supply.

IC Role / Device Role / Timing Role: LIN slave node managing actuator control, switch inputs, and configuration persistence via data flash. Use Value: UART with LIN-bus support enables direct compliance with ISO 17987-4; data flash replaces external EEPROM, reducing BOM count and board area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100SLAFB#X0 | Same package, same 128 KB flash, but 128-pin LQFP (0.65-mm pitch) instead of LFQFP (0.5-mm pitch) | Requires PCB layout change due to different footprint and pitch; identical peripheral set and firmware compatibility | Select for legacy LQFP assembly lines or where 0.65-mm pitch improves solder joint reliability under thermal cycling |
| R5F101SHAFB#X0 | Pin-compatible 128-pin LFQFP variant without data flash (0 KB); otherwise identical flash/RAM/peripherals | Not suitable for applications requiring field-updatable calibration or event logging; reduces cost where EEPROM is externally added | Select when nonvolatile parameter storage is handled externally, or when lower unit cost outweighs integration benefits |
Compared with R5F100SHAFB#X0, R5F100SLAFB#X0 demands PCB redesign but offers identical functionality in a more widely supported LQFP footprint, while R5F101SHAFB#X0 removes data flash to cut cost and simplify qualification - making it viable only when external nonvolatile storage is acceptable.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100SHAFB#X0?
The R5F100SHAFB#X0 operates at up to 32 MHz with the high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - enabling flexible trade-offs between speed and energy in the R5F100SHAFB#X0.
Does the R5F100SHAFB#X0 include on-chip data flash, and what are its endurance and voltage requirements?
Yes, the R5F100SHAFB#X0 integrates 8 KB of on-chip data flash memory rated for 1,000,000 write/erase cycles (typical). It supports background operation (BGO), allowing program execution from code flash while rewriting data flash. Voltage requirements for rewrites are VDD = 1.8 to 5.5 V - fully compatible with the R5F100SHAFB#X0's main supply range.
What industrial temperature grade does the R5F100SHAFB#X0 support, and how is it indicated in the part number?
The R5F100SHAFB#X0 is qualified for industrial operation from −40°C to +85°C, denoted by the "D" grade in its family designation (RL78/G13-D). This grade appears implicitly in the ordering code structure and is confirmed in Renesas documentation - ensuring the R5F100SHAFB#X0 meets extended temperature requirements for factory automation and infrastructure applications.
How many analog input channels and what ADC resolution does the R5F100SHAFB#X0 provide?
The R5F100SHAFB#X0 features a 10-bit successive-approximation ADC with up to 26 analog input channels (ANI0–ANI25). It includes an internal 1.45 V reference voltage and a calibrated temperature sensor - both accessible through dedicated ADC channels - providing accurate sensing capabilities essential for the R5F100SHAFB#X0's role in environmental and metrology systems.
Is the R5F100SHAFB#X0 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100SHAFB#X0 is pin-compatible with other 128-pin LFQFP RL78/G13 devices sharing the same FB suffix and pin count (e.g., R5F100SJAFB#X0, R5F100SKAFB#X0), differing only in flash/RAM sizing and data flash presence. Firmware portability is maintained across these variants, though register-level initialization may require verification for memory-mapped peripheral differences in the R5F100SHAFB#X0.
