Product details
Overview
R5F101SHDFB#50 from Renesas is a 128-pin LFQFP (14 × 20 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with no data flash, 128 KB code flash, 12 KB RAM, and operation from −40°C to +85°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active current, and supports ultra-low-power STOP mode (0.57 μA) with RTC + LVD - ideal for battery-powered industrial sensors and metering endpoints.
For engineers reviewing the R5F101SHDFB#50 datasheet, R5F101SHDFB#50 pinout, R5F101SHDFB#50 application, or R5F101SHDFB#50 equivalent, key selection considerations include its 128-pin LFQFP-0.5mm package, absence of on-chip data flash, industrial temperature rating (−40°C to +85°C), integrated 10-bit ADC (26 channels), and dual UART/LIN support for robust serial communication in constrained environments.
Technical Context
The R5F101SHDFB#50 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 map spans 1 MB address space, with dedicated SFR regions enabling efficient peripheral control via bit-manipulation instructions.
Power management includes hardware HALT/STOP/SNOOZE modes, on-chip POR and 14-level LVD, and independent clock domains for main (up to 32 MHz) and subsystem (32.768 kHz) operation. Peripheral integration features 16× 16-bit timers, real-time clock with calendar/alarm, 3× I²C, 4× UART/LIN, 2× CSI, 10-bit ADC with internal 1.45 V reference and temperature sensor, and DMA controller with 4 channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101SHAFB#50 | Same 128-pin LFQFP package and 128 KB flash, but rated for −40°C to +105°C (G-grade) and includes data flash (8 KB) | Required where extended temperature operation or non-volatile parameter storage is needed | Select R5F101SHAFB#50 if data flash persistence or +105°C operation is mandatory; otherwise R5F101SHDFB#50 offers lower cost and same core functionality |
| R5F101SJDFB#50 | Identical package, temperature grade, and flash/RAM (128 KB/12 KB), but pinout differs - P10/P11 functions reassigned; no SCL00/SDA00 on those pins | Used when alternate peripheral mapping better suits PCB layout or avoids signal crosstalk | Choose R5F101SJDFB#50 only when its specific pin assignment (e.g., relocated I²C) improves routing or EMI performance in your design |
Compared with R5F101SHAFB#50, the R5F101SHDFB#50 trades data flash and extended temperature for lower unit cost and identical real-time control capability; versus R5F101SJDFB#50, it provides standardized I²C placement at P10/P11, simplifying interoperability with reference schematics and existing firmware libraries.

FAQ
What is the flash memory configuration of the R5F101SHDFB#50?
The R5F101SHDFB#50 contains 128 KB of code flash memory and no data flash memory. This configuration supports firmware storage and self-programming with boot swap functionality, but does not include dedicated non-volatile parameter storage. The absence of data flash reduces cost and is typical for applications that store configuration externally or use code flash sectors for emulation.
Does the R5F101SHDFB#50 support hardware debugging?
Yes, the R5F101SHDFB#50 includes an on-chip debug function compatible with Renesas E2 emulator and CS+ IDE. Debug signals (TOOLRxD/TOOLTxD) are assigned to pins P11 and P12, enabling full SWD-style debugging including breakpoints, watchpoints, and real-time variable inspection without requiring additional debug headers.
What are the low-power operating modes supported by the R5F101SHDFB#50?
The R5F101SHDFB#50 supports HALT, STOP, and SNOOZE modes. In STOP mode with RTC and LVD enabled, it draws just 0.57 μA - critical for battery-backed applications. HALT mode reduces current to 66 μA/MHz, while SNOOZE allows selected peripherals (e.g., UART, ADC) to operate autonomously during CPU sleep, minimizing wake-up latency.
Is the R5F101SHDFB#50 pin-compatible with other RL78/G13 128-pin variants?
The R5F101SHDFB#50 shares the same 128-pin LFQFP-0.5mm mechanical footprint and core pinout (e.g., power, reset, clocks, JTAG) with other SHx variants like R5F101SHAFB#50 and R5F101SJDFB#50. However, functional pin assignments (e.g., I²C location) differ between SH and SJ suffixes - verify per datasheet section "Pin Configuration" before substitution.
What ADC capabilities does the R5F101SHDFB#50 provide?
The R5F101SHDFB#50 integrates a 10-bit successive-approximation ADC with up to 26 analog input channels, internal 1.45 V reference voltage, and an on-die temperature sensor. It supports scan mode, window comparison, and hardware-triggered conversions synchronized to timers - enabling precise sensor acquisition without external reference or signal conditioning.
