Overview
R5F104GDAFB#X0 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (G) 16-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 8 KB data flash. It delivers 44 DMIPS at 32 MHz, operates from 1.6–5.5 V, and supports ultra-low-power modes (0.60 μA RTC+LVD). It targets battery-powered industrial sensors and smart metering interfaces.
For engineers reviewing the R5F104GDAFB#X0 datasheet, R5F104GDAFB#X0 pinout, R5F104GDAFB#X0 application, or R5F104GDAFB#X0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, 96 KB/12 KB/8 KB memory configuration, -40 to +105°C operation, integrated RTC+LVD low-power retention, and peripheral mix including 10-channel I²C, 4 UART/LIN, and 12-bit ADC with temperature sensor.
Technical Context
The R5F104GDAFB#X0 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It integrates a Data Transfer Controller (DTC) for autonomous memory transfers and an Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention.
Its mixed-signal subsystem includes an 8/10-bit ADC with 12 analog inputs, internal 1.45 V reference and temperature sensor, dual 8-bit DAC outputs, and two comparators with window mode. Clock management features a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) and support for external crystals up to 20 MHz.
