Product details
Overview
R5F101LLDFB#X0 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), data-flash-free variant of the RL78/G13 16-bit MCU family, delivering 41 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.57 μA in RTC+LVD mode), 128 KB flash, 12 KB RAM, and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART, I²C, and CSI for industrial control and sensor interface applications.
For engineers reviewing the R5F101LLDFB#X0 datasheet, R5F101LLDFB#X0 pinout, R5F101LLDFB#X0 application, or R5F101LLDFB#X0 equivalent, key selection considerations include its 64-pin LFQFP-0.5mm package, absence of data flash memory, industrial-grade temperature range (–40°C to +85°C), and support for low-power real-time operation with RTC and LVD.
Technical Context
The R5F101LLDFB#X0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, 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, calendar-based real-time clock with alarm and correction functions, and a watchdog timer powered by a dedicated low-speed on-chip oscillator.
Peripherals include up to 16 channels of 16-bit timer, 3–10 channels of I²C/Simplified I²C, 2–4 UART/LIN channels, 2–8 CSI channels, and an 8/10-bit A/D converter with internal 1.45 V reference and temperature sensor - all operating across 1.6–5.5 V supply and –40°C to +85°C ambient.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101LLAFB#X0 | Same 64-pin LFQFP package and 128 KB flash, but rated for consumer temp range (–40°C to +85°C, A-grade) and lacks industrial qualification | Targeted for cost-sensitive consumer electronics where extended temperature validation is unnecessary | Select when industrial-grade reliability testing and documentation are not required |
| R5F100LLDFB#X0 | Identical package, pinout, and 128 KB flash, but includes 8 KB data flash memory and supports background operation (BGO) | Suitable for applications requiring frequent nonvolatile parameter storage (e.g., calibration data, event logs) without halting program execution | Choose when field-updatable configuration storage or wear-leveling over 1M rewrite cycles is essential |
Compared with R5F101LLDFB#X0, R5F101LLAFB#X0 omits industrial qualification while retaining identical core specs, whereas R5F100LLDFB#X0 adds 8 KB data flash with BGO - making it preferable for systems needing robust parameter retention without CPU intervention.

What is the flash memory configuration of the R5F101LLDFB#X0?
The R5F101LLDFB#X0 contains 128 KB of code flash memory with 1 KB erase blocks, self-programming capability, and boot swap functionality. It does not include data flash memory - unlike the R5F100xx variants - making it ideal for applications where firmware-only storage is sufficient and BGO is not required.
Does the R5F101LLDFB#X0 support real-time clock functionality?
Yes, the R5F101LLDFB#X0 integrates a full-featured real-time clock (RTC) with calendar support (99-year range), alarm interrupt, and automatic clock correction. It operates independently in STOP mode with only 0.57 μA current draw when paired with the on-chip LVD, enabling reliable timekeeping in battery-powered systems.
What is the operating temperature grade of the R5F101LLDFB#X0?
The R5F101LLDFB#X0 is rated for industrial operation from –40°C to +85°C (D-grade), as indicated by the "D" in its part number suffix. This qualification ensures reliability in harsh environments such as factory floors, outdoor metering enclosures, and HVAC equipment without derating.
How many analog input channels does the R5F101LLDFB#X0 support?
The R5F101LLDFB#X0 supports up to 26 analog input channels on its 10-bit A/D converter, with dedicated AVREFP/AVREFM pins for precise reference voltage control. The internal 1.45 V reference and integrated temperature sensor are accessible for calibration and environmental compensation tasks.
Is the R5F101LLDFB#X0 pin-compatible with other RL78/G13 64-pin variants?
Yes, the R5F101LLDFB#X0 shares identical pinout and LFQFP-64 (10 × 10 mm, 0.5-mm pitch) packaging with all other RL78/G13 64-pin members, including R5F100LLDFB#X0 and R5F101LLAFB#X0. Functional differences (e.g., data flash presence, temperature grade) do not affect mechanical or electrical compatibility.
What debug interface does the R5F101LLDFB#X0 use?
The R5F101LLDFB#X0 supports on-chip debugging via the built-in FINE (Fast In-Circuit Emulator) interface, accessible through dedicated pins (e.g., P11 for TOOLRxD). It requires no external debug probe beyond standard SWD/JTAG adapters compatible with Renesas E2 studio and CS+ toolchains.
