Product details
Overview
R5F100SLDFB#50 from Renesas is a 128-pin LFQFP (14 × 20 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit MCU with 512 KB flash, 8 KB data flash, 32 KB RAM, and ultra-low power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode) for embedded control in HVAC, motor drives, and smart meters.
For engineers reviewing the R5F100SLDFB#50 datasheet, R5F100SLDFB#50 pinout, R5F100SLDFB#50 application, or R5F100SLDFB#50 equivalent, key selection criteria include its 128-pin LFQFP-0.5mm package, -40°C to +85°C industrial temperature grade (D suffix), integrated RTC with calendar/alarm, 26-channel 10-bit ADC, and dual UART/LIN support for robust serial communication in resource-constrained systems.
Technical Context
The R5F100SLDFB#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). It integrates a 12-bit interval timer, real-time clock with 99-year calendar and clock correction, and watchdog timer with dedicated low-speed oscillator.
Its peripheral set includes up to 16 channels of 16-bit timer, 3–10 channels of I²C/Simplified I²C, 2–4 UART/LIN interfaces, 2–8 CSI (SPI-compatible) channels, and DMA controller with 4 channels - enabling deterministic timing and efficient data movement in closed-loop control applications.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101SLDFB#50 | No data flash memory (0 KB); identical core, peripherals, and package. | Not suitable for applications requiring nonvolatile parameter storage or firmware update capability. | Select when data retention is handled externally or unnecessary; reduces cost and flash programming complexity. |
| R5F100SLDKB#50 | Same flash/RAM specs but in 128-pin LQFP (14 × 20 mm, 0.65-mm pitch); different pinout and thermal profile. | Requires PCB redesign due to pitch and footprint mismatch; not drop-in compatible. | Choose only if existing layout uses 0.65-mm pitch LQFP and thermal dissipation requirements align. |
Compared with R5F100SLDFB#50, R5F101SLDFB#50 removes data flash to reduce cost and die size while retaining full code flash and peripheral functionality, whereas R5F100SLDKB#50 offers identical features in a mechanically incompatible 0.65-mm pitch package-making the former a functional alternative and the latter a layout-dependent option.
