Product details
Overview
R5F100LKDFB#30 from Renesas is a 64-pin LFQFP (10 × 10 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 384 KB flash, 8 KB data flash, 24 KB RAM, 32 MHz max CPU speed, and ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces requiring robust timing, analog sensing, and LIN/UART communication.
For engineers reviewing the R5F100LKDFB#30 datasheet, R5F100LKDFB#30 pinout, R5F100LKDFB#30 application, or R5F100LKDFB#30 equivalent, key selection criteria include its 64-pin LFQFP-0.5mm package, integrated RTC with calendar/alarm, 26-channel 10-bit ADC, dual UART/LIN support, and industrial temperature range (−40°C to +105°C).
Technical Context
The R5F100LKDFB#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting variable instruction execution time (0.03125 μs at 32 MHz to 30.5 μs at 32.768 kHz). It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–32 MHz), DMA controller (4 channels), and hardware multiplier/divider for real-time signal processing.
Its peripheral set includes up to 16× 16-bit timers, 3× I²C/Simplified I²C channels, 2× CSI (SPI-compatible) interfaces, and a background operation-capable data flash enabling concurrent code execution during rewrites - critical for firmware-over-the-air updates in field-deployed devices.
