Product details
Overview
R5F101SLDFB#10 from Renesas is a 128-pin LFQFP (14 × 20 mm, 0.5-mm pitch), 16-bit RL78/G13 microcontroller with 128 KB flash memory, 12 KB RAM, and no data flash memory. It operates from 1.6 V to 5.5 V, achieves 41 DMIPS at 32 MHz, and supports ultra-low-power modes including STOP (0.57 μA) and HALT - used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F101SLDFB#10 datasheet, R5F101SLDFB#10 pinout, R5F101SLDFB#10 application, or R5F101SLDFB#10 equivalent, key selection criteria include its 128-pin LFQFP-0.5mm package, absence of on-chip data flash, -40°C to +85°C industrial temperature grade (D), and integrated RTC, 10-bit ADC (26 channels), and multiple serial interfaces (UART, I²C, CSI).
Technical Context
The R5F101SLDFB#10 implements the RL78 CPU core with a 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 subsystem clock). It integrates a 12-bit interval timer, real-time clock with calendar/alarm functions, and watchdog timer with dedicated low-speed oscillator.
It features dual-voltage I/O capability (1.8/2.5/3.0 V interface support), on-chip voltage detector (LVD) with 14 selectable levels, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM - critical for deterministic sensor data acquisition and low-latency peripheral handling in embedded control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Core Architecture | RL78 16-bit CISC with 3-stage pipeline; enables efficient code density and deterministic interrupt latency for real-time control. |
| Max Operating Frequency | 32 MHz; delivers 41 DMIPS performance suitable for motor control and protocol stack execution. |
| Flash Memory | 128 KB code flash (1 KB block size); supports self-programming with boot swap and flash shield window security. |
| RAM | 12 KB on-chip RAM; sufficient for RTOS operation and multi-channel sensor buffering. |
| ADC | 10-bit resolution, 26 input channels, internal 1.45 V reference and temperature sensor; enables direct analog monitoring without external components. |
| Low-Power Modes | STOP mode draws 0.57 μA (RTC + LVD active); HALT mode consumes 66 μA/MHz - optimized for battery life in intermittent-sensing applications. |
| Operating Voltage | 1.6 V to 5.5 V single supply; allows direct connection to Li-ion, alkaline, or regulated 3.3 V/5 V rails without level-shifting. |
| Temperature Range | -40°C to +85°C (Industrial Grade D); qualified for deployment in factory automation and outdoor metering environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101SLDFB#30 | Identical silicon, different packaging specification (embossed tape vs. tray); same electrical specs and pinout. | No functional difference; selected based on SMT line feed requirements (tape-and-reel vs. tray). | Choose #30 for automated pick-and-place; #10 for manual prototyping or low-volume assembly. |
| R5F100SLDFB#10 | Same package and pinout, but includes 8 KB data flash memory and operates at -40°C to +85°C (Grade D). | Enables EEPROM-like parameter storage without external memory; adds ~$0.15 BOM cost. | Select when field-updatable calibration tables or event logs require persistent nonvolatile storage beyond code flash. |
Compared with R5F101SLDFB#10, the #30 variant offers identical functionality in tape format for production lines, while R5F100SLDFB#10 adds data flash for configuration retention - making it preferable for applications requiring frequent parameter writes without wear-leveling overhead.

FAQ
Does R5F101SLDFB#10 include on-chip data flash memory?
No, R5F101SLDFB#10 does not include data flash memory. The "101" in the part number explicitly indicates no data flash (per Renesas RL78/G13 ordering guide). Code flash is 128 KB, and RAM is 12 KB. Applications requiring nonvolatile parameter storage must use code flash sectors with wear-leveling software or external EEPROM.
What is the maximum ADC input channel count supported by R5F101SLDFB#10?
R5F101SLDFB#10 supports up to 26 analog input channels (ANI0–ANI25) with 10-bit resolution. This includes dedicated pins like P20/ANI0 and P21/ANI1, plus multiplexed I/O pins configurable as additional analog inputs - confirmed in the RL78/G13 datasheet Section 1.1 Features and Pin Configuration diagrams.
Is R5F101SLDFB#10 pin-compatible with R5F100SLDFB#10?
Yes, R5F101SLDFB#10 and R5F100SLDFB#10 share identical 128-pin LFQFP-0.5mm mechanical footprint and pin mapping. The only differences are internal (presence/absence of data flash and minor ROM configuration bits), making them drop-in replacements where data flash is not required.
What debug interface does R5F101SLDFB#10 support?
R5F101SLDFB#10 supports on-chip debug via the single-wire debug (SWD) interface using the TOOL0 pin (shared with P11). It is compatible with Renesas E2 emulator and third-party tools supporting RL78 SWD protocol - enabling full breakpoint, watchpoint, and memory inspection capabilities without dedicated JTAG pins.
Can R5F101SLDFB#10 operate from a 1.8 V supply?
Yes, R5F101SLDFB#10 supports operation from 1.6 V to 5.5 V. At 1.8 V, it can run up to 16 MHz (per datasheet DC characteristics), maintaining full peripheral functionality including ADC, timers, and serial interfaces - ideal for energy-harvesting or coin-cell powered designs.
