Product details
Overview
R5F101MLAFB#X0 from Renesas is an RL78/G13 80-pin, 5 V-tolerant 16-bit microcontroller with 128 KB flash memory, 12 KB RAM, and no data flash, designed for ultra-low-power industrial control applications operating from −40°C to +105°C. It delivers 41 DMIPS at 32 MHz, consumes 66 μA/MHz active current and 0.57 μA in RTC+LVD-only mode, and integrates 16-bit timers, 10-bit ADC (26 channels), UART, I²C, CSI, and real-time clock.
For engineers reviewing the R5F101MLAFB#X0 datasheet, R5F101MLAFB#X0 pinout, R5F101MLAFB#X0 application, or R5F101MLAFB#X0 equivalent, key selection criteria include its LFQFP-80 (12 × 12 mm, 0.5 mm pitch) package, industrial-grade temperature range (−40°C to +105°C), absence of on-chip data flash, and support for SNOOZE/STOP/HALT low-power modes in resource-constrained embedded systems.
Technical Context
The R5F101MLAFB#X0 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 features a 1 MB address space, four banks of 8-bit general-purpose registers, and on-chip power management including POR, LVD (14-level selectable), and dedicated low-speed watchdog timer.
Its peripheral set includes up to 16 channels of 16-bit timer, one 12-bit interval timer, calendar-based RTC with alarm and correction, 8/10-bit ADC with internal 1.45 V reference and temperature sensor, and three serial interface types-CSI (SPI-compatible), UART/LIN, and I²C-each configurable across multiple channels with independent clock sources.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101MLAFB#V0 | Identical silicon; differs only in packaging - supplied in tray (PLQP0080KE-A) instead of embossed tape (#X0) | No functional difference; suited for manual prototyping or small-batch assembly where tape-and-reel is not required | Select #V0 for evaluation or low-volume production; #X0 preferred for automated SMT lines |
| R5F100MLAFB#X0 | Same package and pinout, but includes 8 KB data flash and operates at −40°C to +85°C (D-grade) | Enables EEPROM-like nonvolatile parameter storage; limited to commercial/industrial ambient conditions without extended temperature qualification | Choose when data logging or field calibration is required and extended temperature is not mandatory |
Compared with R5F101MLAFB#X0, the #V0 variant offers identical functionality with tray packaging for flexibility in development, while R5F100MLAFB#X0 adds data flash at the cost of reduced temperature range - making the R5F101MLAFB#X0 optimal for thermally demanding, flash-parameter-free control tasks.

FAQ
What is the maximum operating frequency and performance of the R5F101MLAFB#X0?
The R5F101MLAFB#X0 operates at up to 32 MHz and delivers 41 DMIPS. Its RL78 CPU core supports dynamic clock switching between a high-accuracy ±1.0% on-chip oscillator and a 32.768 kHz crystal, enabling both high-speed computation and precision real-time clock operation. This performance level is validated across the full −40°C to +105°C industrial temperature range specified for the R5F101MLAFB#X0.
Does the R5F101MLAFB#X0 include on-chip data flash memory?
No, the R5F101MLAFB#X0 does not include on-chip data flash memory. As indicated by the "101" in its part number per Renesas' naming convention, this variant provides 128 KB of code flash and 12 KB of RAM but omits the 4–8 KB data flash found in "100" series counterparts like R5F100MLAFB#X0. All nonvolatile parameter storage must be implemented externally or via code flash wear-leveling techniques.
What package type and pin count does the R5F101MLAFB#X0 use?
The R5F101MLAFB#X0 uses an 80-pin LFQFP package with 12 × 12 mm body size and 0.5 mm pitch (Renesas code PLQP0080KE-A). The "FB" suffix in the part number explicitly denotes the LFQFP-0.5 mm pitch variant, and the "#X0" indicates embossed tape packaging - optimized for automated surface-mount assembly.
What is the operating temperature grade of the R5F101MLAFB#X0?
The R5F101MLAFB#X0 is rated for industrial operation from −40°C to +105°C (G-grade). This extended temperature range is confirmed by Renesas' official ordering information and qualifies the device for under-hood automotive, factory automation, and HVAC applications where ambient thermal stress exceeds standard commercial or industrial (−40°C to +85°C) limits.
How does the R5F101MLAFB#X0 support low-power system design?
The R5F101MLAFB#X0 supports low-power design through multiple hardware-optimized modes: HALT (0.94 μA), STOP (0.57 μA with RTC + LVD), and SNOOZE (active background data flash rewrite). Its 66 μA/MHz active current, programmable LVD with 14 voltage thresholds, and dedicated low-speed watchdog oscillator allow precise power budgeting in battery-powered or energy-harvested systems - all verified for the R5F101MLAFB#X0's G-grade specification.
