Product details
Overview
R5F101MKDFA#30 from Renesas is a 32-bit RL78/G13 microcontroller with 256 KB flash memory, 8 KB data flash, and 20 KB RAM, operating at up to 32 MHz with 41 DMIPS performance. It features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD mode), 16-bit A/D converter (10-bit resolution, 26 channels), real-time clock, and multiple serial interfaces (UART, I²C, CSI) for industrial control and sensor node applications.
For engineers reviewing the R5F101MKDFA#30 datasheet, R5F101MKDFA#30 pinout, R5F101MKDFA#30 application, or R5F101MKDFA#30 equivalent, key selection criteria include its 80-pin LQFP-0.65mm package, industrial-grade -40°C to +85°C operation (D-grade), absence of on-chip data flash (indicated by "101" in part number), and integrated low-voltage detection with 14-level programmable thresholds.
Technical Context
The R5F101MKDFA#30 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, supporting variable instruction execution time from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). Its memory subsystem includes 256 KB code flash with 1 KB block erase, self-programming capability with boot swap, and background operation during data flash rewriting.
Peripherals are tightly integrated: 16-channel 16-bit timer, 12-bit interval timer, calendar-based real-time clock with alarm and correction, watchdog timer with dedicated low-speed oscillator, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM. Serial connectivity includes up to 4 UART/LIN channels, 10 I²C/Simplified I²C channels, and 8 CSI channels - all configurable per pin function mapping.

Equivalent & Alternatives
The following parts are listed as comparable options for similar microcontroller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| R5F101MKDFA#50 | Identical silicon; differs only in packaging (embossed tape vs. tray) | No functional difference; suited for automated SMT assembly requiring tape-and-reel feed | Select #50 for high-volume pick-and-place production; #30 for manual prototyping or low-volume builds |
| R5F100MKDFA#30 | Same package and pinout, but includes 8 KB data flash (vs. none in R5F101MKDFA#30) | Requires data logging or parameter storage; adds ~1 KB RAM usage for flash library | Choose R5F100MKDFA#30 when non-volatile parameter retention is required; R5F101MKDFA#30 optimizes cost where data flash is unnecessary |
