Product details
Overview
R5F100MLDFB#70 from Renesas is an RL78/G13 80-pin, 512 KB flash, 32 KB RAM, 8 KB data flash microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply, and integrated peripherals including 16-bit timers, 10-bit ADC (26 channels), UART/LIN, I²C, CSI, RTC, and DMA - deployed in industrial motor control and sensor-based HMI systems.
For engineers reviewing the R5F100MLDFB#70 datasheet, R5F100MLDFB#70 pinout, R5F100MLDFB#70 application, or R5F100MLDFB#70 equivalent, key selection criteria include its LFQFP-80 (12×12 mm, 0.5 mm pitch) package, -40°C to +85°C industrial temperature grade (D), on-chip debug support, self-programmable flash with boot swap, and background data flash rewriting capability.
Technical Context
The R5F100MLDFB#70 implements the RL78 CPU core with a 3-stage CISC 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 high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), hardware multiplier/divider, and BCD correction circuit.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F100MLAFB#70 | Same 80-pin LFQFP package and 512 KB/32 KB/8 KB memory, but consumer-grade (-40°C to +85°C, A-marking) instead of industrial D-grade | Limited to commercial environments without extended thermal stress or long-term reliability validation | Select only if operating ambient stays within validated A-grade specs and cost sensitivity outweighs industrial qualification needs |
| R5F101MLDFB#70 | Identical package and pinout, but lacks data flash memory (0 KB vs. 8 KB); retains same code flash, RAM, and peripherals | Not suitable for applications requiring nonvolatile parameter storage or field-upgradable configuration tables | Choose when firmware-only storage suffices and BGO-based runtime reconfiguration is unnecessary |
Compared with R5F100MLDFB#70, R5F100MLAFB#70 trades industrial temperature certification for lower cost, while R5F101MLDFB#70 removes data flash to reduce silicon area - both require careful evaluation of thermal margin and nonvolatile data retention requirements before substitution.

FAQ
What is the maximum operating frequency and corresponding instruction timing for R5F100MLDFB#70?
The R5F100MLDFB#70 supports up to 32 MHz operation using the high-speed on-chip oscillator. At this frequency, the minimum instruction execution time is 0.03125 μs. The device also supports slower clocks down to 32.768 kHz (subsystem clock), where the minimum instruction time extends to 30.5 μs - enabling flexible trade-offs between performance and power consumption in the R5F100MLDFB#70 design.
Does R5F100MLDFB#70 support in-system programming and secure firmware updates?
Yes, the R5F100MLDFB#70 includes on-chip debug functionality and full self-programming capability for both code and data flash. It supports boot swap and flash shield window features to protect critical firmware sections during field updates. These capabilities allow secure, verified firmware upgrades without requiring external programmers - a core feature of the R5F100MLDFB#70's embedded security architecture.
How many analog input channels does R5F100MLDFB#70 provide, and what ADC resolution is supported?
The R5F100MLDFB#70 integrates a 10-bit successive approximation ADC with up to 26 analog input channels, including dedicated pins like P20/ANI0, P21/ANI1, P22/ANI2, and P147/ANI18. It also includes an internal 1.45 V reference voltage and temperature sensor - all accessible within the 80-pin LFQFP package. This ADC capability is fully specified and validated for the R5F100MLDFB#70 across its operating voltage and temperature range.
What low-power modes are available on R5F100MLDFB#70, and what is the lowest achievable current draw?
The R5F100MLDFB#70 offers HALT, STOP, and SNOOZE low-power modes. In STOP mode with only RTC and LVD active, it achieves 0.57 μA typical current draw at VDD = 3.0 V and TA = 25°C. This ultra-low quiescent current enables multi-year battery operation in always-on sensor applications - a confirmed specification for the R5F100MLDFB#70 per its official datasheet.
Is R5F100MLDFB#70 pin-compatible with other RL78/G13 variants in the same package?
Yes, all RL78/G13 devices in the 80-pin LFQFP package - including R5F100MLDFB#70, R5F100MLAFB#70, and R5F101MLDFB#70 - share identical pinouts and mechanical footprint. This allows direct substitution within the same package family for memory or feature scaling, provided software and thermal constraints are verified. Pin compatibility is guaranteed by Renesas for the R5F100MLDFB#70 across its designated package group.
