Product details
Overview
R5F100MKDFB#70 from Renesas is an RL78/G13 80-pin LFQFP microcontroller with 256 KB flash, 8 KB data flash, and 20 KB RAM, operating from 1.6 V to 5.5 V at up to 32 MHz (41 DMIPS), featuring ultra-low-power HALT/STOP/SNOOZE modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in industrial motor control, sensor hubs, and smart metering systems.
For engineers reviewing the R5F100MKDFB#70 datasheet, R5F100MKDFB#70 pinout, R5F100MKDFB#70 application, or R5F100MKDFB#70 equivalent, key selection criteria include its -40°C to +105°C industrial temperature grade (G), LFQFP-80 0.5-mm pitch package, on-chip debug support, self-programmable flash with boot swap, and background data flash rewriting capability.
Technical Context
The R5F100MKDFB#70 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 integrates dual-voltage domain I/O for 1.8/2.5/3.0 V interface compatibility and includes a dedicated low-speed on-chip oscillator for watchdog timer operation independent of main clock stability.
Its memory subsystem features 256 KB code flash (1 KB block size, security-protected erase/write), 8 KB data flash with 1,000,000 write cycles and background operation (BGO), and 20 KB SRAM - with flash library RAM usage starting at address FAF00H. Power management includes POR, 14-level LVD with interrupt/reset options, and DMA controller with 4 channels supporting 2-clock transfers between SFR and RAM.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100MKDFB#70?
The R5F100MKDFB#70 operates at up to 32 MHz using its high-speed on-chip oscillator, delivering 41 DMIPS performance. Its minimum instruction execution time is 0.03125 μs under this condition, and it supports dynamic clock scaling down to 32.768 kHz for ultra-low-power RTC operation - all within the same R5F100MKDFB#70 device without external components.
Does the R5F100MKDFB#70 support in-system programming and secure firmware updates?
Yes, the R5F100MKDFB#70 supports full in-system programming via its on-chip debug interface and includes boot swap functionality plus flash shield window protection. These features allow authenticated firmware updates in the field while preventing unauthorized access to code memory - critical for maintaining security and reliability in deployed R5F100MKDFB#70-based systems.
How many analog input channels does the R5F100MKDFB#70 provide, and what is the ADC resolution?
The R5F100MKDFB#70 integrates a 10-bit successive approximation ADC with up to 26 analog input channels (ANI0–ANI26), including dedicated AVREFP/AVREFM pins for precision reference. It also provides an internal temperature sensor and 1.45 V reference voltage - both usable only in high-speed (HS) main mode as specified in the R5F100MKDFB#70 datasheet.
What industrial temperature range is guaranteed for the R5F100MKDFB#70?
The R5F100MKDFB#70 is rated for industrial operation from -40°C to +105°C (G-grade), validated across the full range for electrical parameters including flash read/write, ADC accuracy, oscillator stability, and I/O drive strength. This qualification makes the R5F100MKDFB#70 suitable for under-hood automotive ancillaries, factory automation controllers, and outdoor utility equipment.
Can the R5F100MKDFB#70 operate without an external crystal?
Yes, the R5F100MKDFB#70 can operate entirely from its internal oscillators: a high-speed on-chip oscillator (selectable from 1–32 MHz, ±1.0% accuracy) and a dedicated low-speed oscillator for the watchdog timer. An external 32.768 kHz crystal is optional - used only if enhanced RTC accuracy beyond internal oscillator drift is required in the R5F100MKDFB#70 design.
