Overview
R5F100GAGNA#U0 from Renesas is a 48-pin, 128 KB flash, 8 KB data flash, 12 KB RAM RL78/G13 16-bit microcontroller with ultra-low-power operation (66 μA/MHz active, 0.57 μA RTC+LVD mode), 32 MHz max CPU speed, and integrated 10-bit ADC (26 channels), RTC, and multiple serial interfaces (CSI, UART/LIN, I²C). It targets battery-powered industrial sensors and smart metering endpoints.
For engineers reviewing the R5F100GAGNA#U0 datasheet, R5F100GAGNA#U0 pinout, R5F100GAGNA#U0 application, or R5F100GAGNA#U0 equivalent, key selection criteria include its HWQFN-48 package with 0.5-mm pitch, -40°C to +105°C industrial temperature grade (G suffix), on-chip debug support, and self-programmable flash with boot swap capability.
Technical Context
The R5F100GAGNA#U0 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 subsystem clock).
