Product details
Overview
R5F100SKAFB#30 from Renesas is a 128-pin LFQFP (14 × 20 mm, 0.5-mm pitch), industrial-grade RL78/G13 16-bit microcontroller with 256 KB flash, 8 KB data flash, 20 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, smart meters, and embedded control systems requiring high integration and long runtime.
For engineers reviewing the R5F100SKAFB#30 datasheet, R5F100SKAFB#30 pinout, R5F100SKAFB#30 application, or R5F100SKAFB#30 equivalent, key selection considerations include its 128-pin LFQFP-0.5mm package, integrated RTC + LVD + BGO-capable data flash, 16-channel 10-bit ADC, and support for UART/LIN, I²C, and CSI interfaces in harsh-temperature environments.
Technical Context
The R5F100SKAFB#30 implements the RL78 CPU core with CISC architecture, 3-stage pipeline, and configurable instruction timing (0.03125 μs @ 32 MHz to 30.5 μs @ 32.768 kHz). It integrates dual-clock domains: high-speed on-chip oscillator (±1.0% accuracy, 1–32 MHz selectable) and dedicated low-speed oscillator for watchdog/RTC.
Its peripheral set includes 4-channel DMA, 16-bit timer array (16 channels), real-time clock with calendar/alarm/correction, 10-bit ADC (26 channels), and serial interfaces-CSI (up to 8 ch), UART/LIN (up to 4 ch), and I²C/Simplified I²C (up to 10 ch)-all accessible via configurable GPIO with N-ch open-drain, TTL input, and pull-up options.
