Product details
Overview
R5F100GADFB#30 from Renesas is a 48-pin LFQFP-packaged 16-bit RL78/G13 microcontroller with 128 KB flash, 8 KB data flash, and 12 KB RAM, operating from 1.6 V to 5.5 V across –40°C to +85°C industrial temperature range. It delivers 41 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.57 μA RTC+LVD), and integrates 10-bit ADC (26 channels), real-time clock, UART/SPI/I²C interfaces, and DMA for embedded control in metering and sensor nodes.
For engineers reviewing the R5F100GADFB#30 datasheet, R5F100GADFB#30 pinout, R5F100GADFB#30 application, or R5F100GADFB#30 equivalent, key selection criteria include its industrial-grade temperature rating, integrated data flash with 1M rewrite cycles, low-power STOP/HALT modes, and support for LIN-bus via UART - critical for battery-powered industrial sensing and smart actuator designs.
