Product details
Overview
R5F100MLDFB#10 from Renesas is an RL78/G13 80-pin, 5.5-V, ultra-low-power 16-bit MCU with 512 KB flash, 32 KB RAM, and integrated RTC/LVD, designed for industrial control and sensor node applications operating from -40°C to +105°C.
For engineers reviewing the R5F100MLDFB#10 datasheet, R5F100MLDFB#10 pinout, R5F100MLDFB#10 application, or R5F100MLDFB#10 equivalent, this page delivers verified specifications, package mapping, functional role in real systems, and validated alternative options for design-in and supply continuity.
Technical Context
The R5F100MLDFB#10 implements the RL78 CPU core with a 3-stage CISC pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz), and features a 1 MB address space with four register banks. It integrates dual-clock domain operation: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 16-channel 16-bit timers, 12-bit interval timer, calendar-mode RTC with alarm/correction, 10-bit 26-channel ADC with internal 1.45 V reference and temperature sensor, and multi-protocol serial interfaces (CSI, UART/LIN, I²C) across up to 10 channels - all optimized for deterministic real-time response in resource-constrained embedded systems.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 16-bit microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MLAFB#10 | Same 80-pin LFQFP package and 512 KB flash, but rated for -40°C to +85°C (D-grade) and lacks extended temp qualification | Targeted at commercial/industrial equipment not requiring 105°C operation | Select when ambient temperature stays below +85°C and cost optimization is prioritized over extended thermal margin |
| R5F101MLDFB#10 | Identical pinout and package, but omits data flash memory (0 KB) and reduces RAM to 24 KB | Suitable for firmware-only applications without nonvolatile parameter storage or large buffer requirements | Choose when data logging, calibration storage, or OTA update staging is unnecessary - reduces cost and flash management complexity |
Compared with R5F100MLDFB#10, R5F100MLAFB#10 trades 105°C operation for lower cost in milder environments, while R5F101MLDFB#10 removes data flash to simplify firmware architecture at the expense of field-configurable parameters and long-term data retention.
