Product details
Overview
R5F100LKDFA#30 from Renesas is a 64-pin LQFP-0.65mm, industrial-grade RL78/G13 16-bit microcontroller with 512 KB flash, 8 KB data flash, 32 KB RAM, and true low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD). It integrates 16-bit timers (16 ch), 10-bit ADC (26 ch), UART/LIN (4 ch), I²C (10 ch), CSI (8 ch), RTC, and DMA for embedded control in battery-powered and energy-sensitive systems.
For engineers reviewing the R5F100LKDFA#30 datasheet, R5F100LKDFA#30 pinout, R5F100LKDFA#30 application, or R5F100LKDFA#30 equivalent, key selection criteria include its 512 KB code flash with self-programming and boot swap, -40°C to +85°C industrial temperature rating, integrated LIN support, and hardware BCD correction for metering applications.
Technical Context
The R5F100LKDFA#30 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz). It features dual clock domains: high-speed on-chip oscillator (selectable 1–32 MHz, ±1.0% accuracy) and dedicated low-speed oscillator for watchdog and RTC.
Its peripheral set includes 16-channel 16-bit timer array with input capture/compare, 12-bit interval timer, calendar-mode RTC with alarm and clock correction, and background operation (BGO) for data flash rewriting while executing program code - enabling seamless firmware updates and data logging without halting real-time tasks.
