Product details
Overview
R5F100SHDFB#V0 from Renesas is a 128-pin, LFQFP-0.5 mm pitch, industrial-grade RL78/G13 16-bit microcontroller with 128 KB code flash, 8 KB data flash, and 12 KB RAM. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes (66 μA/MHz active, 0.57 μA RTC+LVD). It targets embedded control in HVAC systems, industrial sensors, and smart metering.
For engineers reviewing the R5F100SHDFB#V0 datasheet, R5F100SHDFB#V0 pinout, R5F100SHDFB#V0 application, or R5F100SHDFB#V0 equivalent, key selection criteria include its 128-pin LFQFP package, -40°C to +105°C industrial temperature grade (G), integrated RTC with calendar/alarm, 26-channel 10-bit ADC, and dual SPI/I²C/UART interfaces for sensor and communication subsystems.
Technical Context
The R5F100SHDFB#V0 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 ultra-low-speed mode). Its memory subsystem includes 128 KB on-chip flash with 1 KB block erase, 8 KB data flash with background operation (BGO), and 12 KB RAM - all accessible across full voltage and temperature ranges.
Peripheral integration includes eight 16-bit timers, one 12-bit interval timer, one real-time clock with calendar and clock correction, one watchdog timer, and a DMA controller with four channels. Serial connectivity comprises up to three CSI (SPI-compatible), three I²C/Simplified I²C, and four UART/LIN channels - configurable per pin mapping in the 128-pin LFQFP layout.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100SLDFB#V0 | Same 128-pin LFQFP package, identical memory (128 KB/8 KB/12 KB), but rated for -40°C to +85°C (D-grade) | Suitable for commercial/industrial environments without extended temperature requirements | Select when operating ambient stays ≤ +85°C and cost optimization is prioritized over extended temp margin |
| R5F101SHAFB#V0 | Same pinout and package, but lacks data flash (0 KB); retains 128 KB code flash and 12 KB RAM | Applicable where firmware-only storage suffices and data logging or parameter persistence is handled externally | Choose when eliminating data flash reduces security complexity and eliminates BGO management overhead |
Compared with R5F100SHDFB#V0, R5F100SLDFB#V0 trades extended temperature range for lower cost in milder environments, while R5F101SHAFB#V0 removes data flash to simplify firmware architecture - both retain identical peripheral sets and real-time performance for drop-in evaluation.

FAQ
What is the maximum operating frequency and corresponding performance of the R5F100SHDFB#V0?
The R5F100SHDFB#V0 achieves a maximum system clock of 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS of processing performance. This rating is measured under typical conditions (VDD = 3.3 V, TA = 25°C) and remains valid across its full industrial temperature range (-40°C to +105°C), enabling deterministic real-time control in demanding applications.
Does the R5F100SHDFB#V0 support self-programming of its code flash memory?
Yes, the R5F100SHDFB#V0 supports self-programming of its 128 KB code flash memory via the on-chip flash library. It includes boot swap functionality and flash shield window protection to prevent unauthorized access. Programming is performed using standard in-application routines without requiring external debug hardware after initial setup.
What are the key low-power modes supported by the R5F100SHDFB#V0, and what peripherals remain active in each?
The R5F100SHDFB#V0 supports HALT, STOP, and SNOOZE modes. In STOP mode (0.57 μA), only the RTC, LVD, and dedicated low-speed oscillator remain active. In SNOOZE mode, selected peripherals like UART or ADC can operate while CPU is halted, enabling event-driven wake-up with minimal power penalty - critical for battery-powered sensor nodes.
Can the R5F100SHDFB#V0's 10-bit ADC measure signals beyond the VDD rail using its internal reference?
No - the R5F100SHDFB#V0's 10-bit ADC uses VDD as the default reference and supports an internal 1.45 V reference (AVREFP/AVREFM) for improved precision. Input voltage must stay within AVREFP and AVREFM (or VDD/GND if internal reference is disabled); it does not support over-VDD measurement or differential inputs beyond the specified analog input range (0 V to AVREFP).
Is the R5F100SHDFB#V0 pin-compatible with other RL78/G13 variants in the same 128-pin LFQFP package?
Yes - all RL78/G13 devices in the 128-pin LFQFP package (e.g., R5F100SJDFB#V0, R5F100SKDFB#V0, R5F100SLDFB#V0) share identical pinouts and electrical characteristics. Firmware and PCB designs are interchangeable across these variants, differing only in memory configuration and temperature grade - enabling scalable design reuse.
