Product details
Overview
R5F100MLDFB#50 from Renesas is an RL78/G13 80-pin, 5V-tolerant 16-bit MCU with 512 KB flash, 8 KB data flash, 32 KB RAM, and integrated RTC/LVD - designed for industrial control panels requiring ultra-low-power operation (66 μA/MHz) and extended temperature support (−40°C to +105°C).
For engineers reviewing the R5F100MLDFB#50 datasheet, R5F100MLDFB#50 pinout, R5F100MLDFB#50 application, or R5F100MLDFB#50 equivalent, key selection criteria include its LFQFP-80 (0.5 mm pitch) package, 32 MHz max CPU speed, 16-channel 10-bit ADC, dual UART/LIN support, and hardware DMA for deterministic sensor-to-actuator response in resource-constrained embedded systems.
Technical Context
The R5F100MLDFB#50 implements the RL78 CISC core with 3-stage pipeline and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz), enabling dynamic power/performance trade-offs across HALT, STOP, and SNOOZE low-power modes. It integrates a high-accuracy ±1.0% on-chip oscillator (1–32 MHz selectable) and dedicated subsystem clock for RTC operation during deep sleep.
Its peripheral set includes up to 16 × 16-bit timers, 3 × I²C/Simplified I²C channels, 2 × CSI (SPI-compatible), 2 × UART/LIN interfaces, and background operation (BGO) for concurrent code execution during data flash rewriting - critical for field-upgradable firmware in industrial gateways and motor controllers.

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#50 | Same 80-pin LFQFP package and 512 KB flash, but rated for −40°C to +85°C (D-grade) instead of +105°C (G-grade) | Limited to non-extended-temperature industrial environments; lacks high-temp qualification for under-hood or furnace proximity use | Select when ambient operating temperature stays ≤ +85°C and cost optimization is prioritized |
| R5F101MLDFB#50 | Identical package and pinout, but no data flash memory (0 KB); retains same code flash, RAM, and peripherals | Not suitable for applications requiring nonvolatile parameter storage or firmware update staging without external EEPROM | Choose when data logging or field firmware updates are handled externally or not required |
Compared with R5F100MLDFB#50, R5F100MLAFB#50 trades extended temperature capability for lower cost in standard industrial settings, while R5F101MLDFB#50 removes data flash to reduce silicon area - both require careful validation of thermal and nonvolatile storage requirements before substitution.
