Product details
Overview
R5F101SLDFB#30 from Renesas is a 32-bit RL78/G13 microcontroller with no data flash memory, 512 KB code flash, 32 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 high integration, real-time clock, multiple serial interfaces, and robust analog peripherals.
For engineers reviewing the R5F101SLDFB#30 datasheet, R5F101SLDFB#30 pinout, R5F101SLDFB#30 application, or R5F101SLDFB#30 equivalent, key selection criteria include its 128-pin LFQFP footprint, absence of on-chip data flash, industrial-grade temperature range (–40°C to +105°C), and support for up to 26-channel 10-bit ADC, 16× 16-bit timers, and 10-channel I²C/Simplified I²C.
Technical Context
The R5F101SLDFB#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling 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 and banked general-purpose registers (8-bit × 8 × 4 banks).
It integrates a 12-bit interval timer, calendar-capable real-time clock (RTC) with alarm and correction functions, watchdog timer with dedicated low-speed oscillator, and background operation (BGO) capable peripherals - though BGO does not apply to data flash (absent in this variant). Serial interface flexibility includes up to 10 channels of I²C/Simplified I²C, 4 UART/LIN channels, and 8 CSI (SPI-compatible) channels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101SLAFB#30 | Same 512 KB flash, 32 KB RAM, and 128-pin LFQFP, but includes 8 KB data flash memory | Required where firmware must store calibration data, usage logs, or user settings non-volatilely without external EEPROM | Select R5F101SLAFB#30 if data flash persistence is mandatory; otherwise R5F101SLDFB#30 reduces cost and simplifies qualification |
| R5F100SLDFB#30 | Identical package and pinout, but only 512 KB flash and 12 KB RAM; no data flash; rated for –40°C to +85°C (D-grade) | Suitable for cost-sensitive industrial applications without extended temperature or large RAM requirements | Choose R5F100SLDFB#30 when 12 KB RAM suffices and +105°C operation is unnecessary - lowers BOM cost |
Compared with R5F101SLAFB#30, the R5F101SLDFB#30 trades data flash capability for lower cost and identical industrial temperature resilience; versus R5F100SLDFB#30, it doubles RAM (32 KB vs. 12 KB) while maintaining same flash and industrial grade - critical for complex real-time tasks and larger RTOS workloads.

FAQ
Does R5F101SLDFB#30 include on-chip data flash memory?
No, R5F101SLDFB#30 does not include data flash memory. The "D" in the part number denotes "Data flash not provided", per Renesas' RL78/G13 ordering convention. This variant relies solely on its 512 KB code flash for program storage and uses on-chip RAM (32 KB) for runtime data. Applications requiring non-volatile parameter storage must use external EEPROM or FRAM.
What is the operating temperature range for R5F101SLDFB#30?
R5F101SLDFB#30 is rated for industrial operation from –40°C to +105°C (G-grade), as confirmed by Renesas' RL78/G13 datasheet Rev.3.80. This extended range supports deployment in harsh environments such as factory floors, outdoor energy infrastructure, and medical equipment with internal thermal buildup.
Which package type and pin count does R5F101SLDFB#30 use?
R5F101SLDFB#30 uses a 128-pin LFQFP package (PLQP0128KD-A) with 14 × 20 mm body and 0.5-mm pitch. The "FB" suffix explicitly indicates LFQFP, and "S" in the part number denotes the 128-pin variant per Renesas' RL78/G13 naming scheme.
Can R5F101SLDFB#30 operate from a single 1.8 V supply?
Yes, R5F101SLDFB#30 supports single-supply operation from 1.6 V to 5.5 V. At 1.8 V, it can run at reduced maximum frequency (up to ~16 MHz per RL78/G13 voltage/frequency specifications), enabling compatibility with low-voltage battery-powered systems while retaining full peripheral functionality including ADC and RTC.
How many I²C channels does R5F101SLDFB#30 support?
R5F101SLDFB#30 supports up to 10 channels of I²C or Simplified I²C communication, as specified in the RL78/G13 datasheet. These channels are implemented as independent hardware modules, allowing concurrent multi-sensor communication (e.g., temperature, humidity, and pressure sensors) without software arbitration overhead.
