Product details
Overview
R5F100SLDFB#10 from Renesas is a 128-pin LFQFP (14 × 20 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 512 KB flash, 32 KB RAM, 8 KB data flash, and real-time clock - designed for low-power embedded control in HVAC, motor drives, and industrial HMI systems.
For engineers reviewing the R5F100SLDFB#10 datasheet, R5F100SLDFB#10 pinout, R5F100SLDFB#10 application, or R5F100SLDFB#10 equivalent, this page delivers verified specifications, package mapping, functional role clarity, and validated alternative options for design-in and supply continuity.
Technical Context
The R5F100SLDFB#10 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz), and operates across -40°C to +105°C (industrial G-grade). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for RTC/WDT.
It features 16-bit timer arrays (16 channels), 10-bit A/D converter (26-channel), multiple serial interfaces (up to 10 I²C/SimpI²C, 4 UART/LIN, 8 CSI), DMA controller (4 channels), and hardware multiplier/divider - all optimized for deterministic real-time control with ultra-low active power (66 μA/MHz) and sub-μA standby (0.57 μA in RTC+LVD mode).

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100SLAFB#10 | Same 512 KB flash, 32 KB RAM, and 128-pin LFQFP package but rated for -40°C to +85°C (D-grade), not +105°C | Not suitable for under-hood or high-ambient industrial enclosures exceeding 85°C | Select when ambient operating temperature stays ≤85°C and cost optimization is prioritized over extended thermal range |
| R5F101SLDFB#10 | Identical package and pinout, but lacks data flash memory (0 KB); retains 512 KB code flash and 32 KB RAM | Cannot store calibrated sensor offsets or user configuration persistently without external EEPROM | Choose when application does not require on-chip nonvolatile parameter storage and BGO-based field updates are unnecessary |
Compared with R5F100SLDFB#10, R5F100SLAFB#10 trades thermal robustness for lower unit cost in benign environments, while R5F101SLDFB#10 removes data flash to simplify qualification and reduce die size - both retain identical peripheral sets and real-time performance for drop-in evaluation where flash architecture permits.

FAQ
What is the maximum operating frequency and corresponding power consumption of the R5F100SLDFB#10?
The R5F100SLDFB#10 achieves up to 32 MHz operation using its high-speed on-chip oscillator, delivering 41 DMIPS at 32 MHz with typical active current of 66 μA/MHz. At full speed and VDD = 3.3 V, total active current is approximately 2.1 mA - verified per R01DS0131EJ0380 Rev.3.80 Section 1.1.
Does the R5F100SLDFB#10 support hardware LIN bus communication?
Yes, the R5F100SLDFB#10 supports LIN 2.2 protocol natively via UART0 with automatic sync-break detection, checksum calculation, and identifier filtering - confirmed in Section 1.1 "Serial interface" of the RL78/G13 datasheet R01DS0131EJ0380.
What is the endurance and voltage range for data flash writes on the R5F100SLDFB#10?
The R5F100SLDFB#10 provides 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) with operation supported across VDD = 1.8 V to 5.5 V - enabling reliable parameter storage even during brown-out conditions, as specified in Section 1.1 "Data Flash Memory".
Is the R5F100SLDFB#10 pin-compatible with other RL78/G13 128-pin variants?
Yes, all RL78/G13 128-pin packages - including R5F100SLDFB#10 (G-grade), R5F100SLAFB#10 (D-grade), and R5F101SLDFB#10 (no data flash) - share identical 128-pin LFQFP mechanical footprint and pin assignment per Figure 1-1 and Table 1-1 in R01DS0131EJ0380.
How does the SNOOZE mode function on the R5F100SLDFB#10, and which peripherals remain active?
In SNOOZE mode, the R5F100SLDFB#10 halts the CPU while keeping selected peripherals - such as UART, ADC, and timer interrupts - operational to respond to events without full wake-up. This mode is configured via the SNZCR register and detailed in Section 22.3.2 of the RL78/G13 User's Manual (R01UH0401EJ0300).
