Product details
Overview
R5F101LLAFB#30 from Renesas is a 64-pin, LFQFP-0.5 mm pitch, 512 KB flash, 32 KB RAM, RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD), 1.6–5.5 V supply, and integrated 10-bit ADC (26 channels), RTC, UART, I²C, SPI, and 16-bit timers - deployed in industrial sensor nodes and battery-powered control systems.
For engineers reviewing the R5F101LLAFB#30 datasheet, R5F101LLAFB#30 pinout, R5F101LLAFB#30 application, or R5F101LLAFB#30 equivalent, key selection criteria include its data flash omission (vs. R5F100xx variants), -40°C to +85°C industrial temperature grade (D), LFQFP-64 package with 0.5-mm pitch, and support for background data flash programming via BGO.
Technical Context
The R5F101LLAFB#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 ultra-low-speed mode). It integrates a 12-bit interval timer, calendar-based real-time clock with alarm and correction, and watchdog timer powered by dedicated low-speed oscillator.
Its peripheral set includes up to 16 channels of 16-bit timer, 3–10 channels of I²C/Simplified I²C, 2–4 UART/LIN channels, 2–8 CSI (SPI-compatible) channels, and DMA controller with 4 channels enabling 2-clock transfers between SFR and RAM - all operating across the full 1.6–5.5 V voltage range and -40°C to +85°C ambient.
