Product details
Overview
R5F101MLAFB#V0 from Renesas is a 80-pin LFQFP, 0.5-mm pitch, 128 KB flash, 12 KB RAM, RL78/G13 16-bit microcontroller with ultra-low power consumption (66 μA/MHz), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F101MLAFB#V0 datasheet, R5F101MLAFB#V0 pinout, R5F101MLAFB#V0 application, or R5F101MLAFB#V0 equivalent, key selection criteria include its data flash omission (vs. R5F100x series), -40°C to +85°C industrial temperature grade (D-grade), and LFQFP-80 package compatibility with high-density PCB layouts requiring thermal reliability and signal integrity.
Technical Context
The R5F101MLAFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz), and features an on-chip high-accuracy ±1.0% oscillator across 1–32 MHz selectable frequencies.
It integrates DMA (4-channel), multiplier/divider/MAC unit, 16-bit timers (16 channels), 12-bit interval timer, watchdog timer, and LVD with 14-level voltage detection - all operating within 1.6–5.5 V supply range and optimized for HALT/STOP/SNOOZE low-power modes.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MLAFB#V0 | Same package, pinout, and peripherals - but includes 8 KB data flash and 12 KB RAM (vs. R5F101MLAFB#V0's 12 KB RAM only). | Required where field firmware updates or parameter storage (e.g., calibration tables) must persist across power cycles. | Select when data flash endurance (1M cycles) and background rewrite capability are mandatory for product lifecycle. |
| R5F101MJAFB#V0 | 64-pin LQFP-64 variant; identical core, flash (128 KB), RAM (12 KB), and feature set - but 16 fewer GPIOs and reduced analog channel count (20 vs. 26). | Suitable for space-constrained designs where full 80-pin I/O is unnecessary and board area savings outweigh peripheral reduction. | Choose for compact industrial HMI or motor driver boards needing lower pin count and simplified layout. |
Compared with R5F100MLAFB#V0, the R5F101MLAFB#V0 trades data flash for lower cost and simpler flash management; compared with R5F101MJAFB#V0, it delivers higher I/O density and expanded analog capability at the expense of larger footprint - making it optimal for complex sensor aggregation or multi-interface gateway roles.
