Product details
Overview
R5F101SHDFB#30 from Renesas is a 32-bit RL78/G13 microcontroller with no data flash memory, 128 KB code flash, 12 KB RAM, and 128-pin LFQFP (0.5 mm pitch) package. It operates from 1.6 V to 5.5 V, delivers 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT. It targets industrial control systems requiring real-time clock, 26-channel 10-bit ADC, and LIN-capable UARTs.
For engineers reviewing the R5F101SHDFB#30 datasheet, R5F101SHDFB#30 pinout, R5F101SHDFB#30 application, or R5F101SHDFB#30 equivalent, key selection criteria include its 128-pin LFQFP-128 package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D suffix), and support for background data flash programming via external memory interface.
Technical Context
The R5F101SHDFB#30 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). It integrates a 12-bit interval timer, calendar-based RTC with alarm and correction, and watchdog timer using dedicated low-speed oscillator.
Peripheral integration includes up to 16 channels of 16-bit timers, 3–10 I²C/Simplified I²C channels, 2–4 UART/LIN interfaces, 2–8 CSI (SPI-compatible) channels, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101SHAFB#30 | Same 128 KB flash, 12 KB RAM, and 128-pin LFQFP package but includes 8 KB data flash memory. | Required where firmware must store calibration tables, event logs, or user settings without external EEPROM. | Select R5F101SHAFB#30 if nonvolatile parameter storage is needed; R5F101SHDFB#30 reduces cost when external flash suffices. |
| R5F101SJDFB#30 | Identical package and temperature grade, but with 192 KB code flash and 16 KB RAM - no data flash. | Suitable for larger firmware images (e.g., embedded web server, OTA stack) requiring >128 KB executable space. | Choose R5F101SJDFB#30 when application code size exceeds 128 KB; pinout and peripheral register map remain identical. |
Compared with R5F101SHAFB#30 and R5F101SJDFB#30, the R5F101SHDFB#30 provides optimal balance of code density, RAM, and cost for mid-complexity industrial controllers where data flash is managed externally or omitted entirely.

The R5F101SHDFB#30 contains 128 KB of on-chip code flash memory and no integrated data flash memory. This configuration targets applications where nonvolatile parameter storage is handled externally or is unnecessary. The flash supports block erase (1 KB), self-programming with boot swap, and flash shield window protection against unauthorized access.
Does the R5F101SHDFB#30 support LIN communication?
Yes, the R5F101SHDFB#30 supports LIN communication through its UART peripherals, which include LIN bus protocol features such as automatic sync-break detection, checksum calculation, and identifier filtering. Two UART channels are available, both capable of LIN 2.2 compliance when configured in LIN mode.
What is the operating temperature range for the R5F101SHDFB#30?
The R5F101SHDFB#30 is rated for industrial operation from -40°C to +85°C, indicated by the "D" suffix in its part number. It is not qualified for the extended -40°C to +105°C range (G-grade) and must be used within this specified ambient temperature envelope for guaranteed electrical performance and reliability.
How many analog input channels does the R5F101SHDFB#30 provide?
The R5F101SHDFB#30 provides up to 26 analog input channels for its 10-bit A/D converter. These channels are distributed across multiple port groups and include dedicated pins such as P20/ANI0, P21/ANI1, P22/ANI2, and higher-numbered channels like P147/ANI18 - all accessible in the 128-pin LFQFP package.
Is the R5F101SHDFB#30 pin-compatible with other RL78/G13 devices in the same package?
Yes, the R5F101SHDFB#30 shares identical pinout, electrical characteristics, and peripheral register mapping with all other RL78/G13 devices in the 128-pin LFQFP package (e.g., R5F101SHAFB#30, R5F101SJDFB#30). Firmware and PCB designs are interchangeable across these variants, differing only in memory configuration and feature enablement.
