Overview
R5F100LFDFB#V0 from Renesas is a 64-pin LFQFP-packaged RL78/G13 16-bit microcontroller with 96 KB flash, 8 KB data flash, and 8 KB RAM, operating from 1.6 V to 5.5 V. It delivers 41 DMIPS at 32 MHz, features ultra-low-power modes (0.57 μA RTC+LVD), integrated 10-bit ADC (26 channels), real-time clock, and UART/I²C/CSI interfaces - deployed in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F100LFDFB#V0 datasheet, R5F100LFDFB#V0 pinout, R5F100LFDFB#V0 application, or R5F100LFDFB#V0 equivalent, key selection criteria include its 64-pin LFQFP-0.5 mm pitch package, 96 KB code flash with self-programming and flash shield window, 8 KB data flash with background operation (BGO), and support for -40°C to +85°C industrial ambient operation.
Technical Context
The R5F100LFDFB#V0 implements the RL78 CPU core with CISC architecture and 3-stage pipeline, enabling instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz subsystem clock). It integrates on-chip power-on-reset (POR), voltage detector (LVD) with 14 selectable levels, and DMA controller with up to 4 channels supporting 2-clock transfers between SFR and RAM.
Its peripheral set includes eight 16-bit timers, one 12-bit interval timer, one calendar-capable real-time clock (RTC), one watchdog timer, and serial interfaces: up to 8 CSI channels, 4 UART/LIN channels, and 10 I²C/Simplified I²C channels - all configurable via dedicated register sets and interrupt vectors mapped to the 1 MB address space.
