Overview
R5F100MKDFB#30 from Renesas is an RL78/G13 80-pin low-power 16-bit MCU with 256 KB flash, 8 KB data flash, and 20 KB RAM, operating from 1.6 V to 5.5 V across –40°C to +105°C industrial temperature range. It integrates a real-time clock, 16-bit timers (12 channels), 10-bit ADC (26 channels), UART/SPI/I²C interfaces, and ultra-low-power HALT/STOP/SNOOZE modes - deployed in smart metering, industrial sensors, and battery-powered HMI control units.
For engineers reviewing the R5F100MKDFB#30 datasheet, R5F100MKDFB#30 pinout, R5F100MKDFB#30 application, or R5F100MKDFB#30 equivalent, key selection criteria include its 80-pin LFQFP-0.5mm package, industrial-grade thermal rating (–40°C to +105°C), integrated data flash with background operation, 32 MHz max CPU speed at 41 DMIPS, and support for LIN-bus via UART.
Technical Context
The R5F100MKDFB#30 implements the RL78 CPU core with 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 RTC mode). Its memory subsystem includes 256 KB code flash (1 KB block size), 8 KB data flash with 1M rewrite cycles, and 20 KB SRAM - all accessible under single-supply 1.6–5.5 V operation.
Peripherals include dual DMA controllers (4 channels), hardware multiplier/divider/MAC, 12-channel 16-bit timer array, calendar-capable RTC with alarm/correction, watchdog timer, and analog subsystem with internal 1.45 V reference and temperature sensor. Serial interfaces comprise up to 4 UARTs (LIN-supported), 8 CSI/SPI channels, and 10 I²C/Simplified I²C channels.

FAQ
What is the maximum operating frequency and corresponding DMIPS rating for the R5F100MKDFB#30?
The R5F100MKDFB#30 operates at up to 32 MHz with a measured performance of 41 DMIPS. This rating reflects its RL78 CPU core's 3-stage pipeline efficiency and is validated under standard test conditions per Renesas documentation. The R5F100MKDFB#30 achieves this without external clock multiplication, relying on its high-accuracy on-chip oscillator.
Does the R5F100MKDFB#30 support LIN bus communication, and how is it implemented?
Yes, the R5F100MKDFB#30 supports LIN bus communication through dedicated UART channels that include LIN-specific features such as break detection, sync field generation, and identifier filtering. These functions are implemented in hardware, eliminating software bit-banging overhead. The R5F100MKDFB#30 requires only an external LIN transceiver to interface with a LIN network.
What are the data flash endurance and rewrite voltage specifications for the R5F100MKDFB#30?
The R5F100MKDFB#30 includes 8 KB of data flash rated for 1,000,000 write/erase cycles (typical) and supports reprogramming across the full supply range of 1.8 V to 5.5 V. Background operation (BGO) allows code execution from main flash while data flash is being rewritten - a key capability confirmed in the R01DS0131EJ0380 datasheet for the RL78/G13 family.
How does the R5F100MKDFB#30 manage ultra-low-power operation in STOP mode?
In STOP mode, the R5F100MKDFB#30 draws just 0.57 μA while maintaining RTC operation and low-voltage detector (LVD) functionality - enabling time-stamped wake-up events and brown-out monitoring without external circuitry. This specification is guaranteed across the full –40°C to +105°C industrial temperature range and is independent of external crystal loading.
Is the R5F100MKDFB#30 pin-compatible with other RL78/G13 variants in the same package?
Yes, the R5F100MKDFB#30 is fully pin-compatible with all other 80-pin LFQFP RL78/G13 devices sharing the FB suffix and #30 packaging code (e.g., R5F100MLDFB#30, R5F101MKDFB#30), including identical pin functions, electrical characteristics, and thermal pad layout. This enables drop-in replacement within the same footprint for memory or feature scaling.
