Product details
Overview
R5F104GGGFB#10 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 128 KB flash, 12 KB RAM, and 8 KB data flash. It delivers 44 DMIPS at 32 MHz, operates from 1.6 V to 5.5 V, and supports ultra-low-power HALT/STOP/SNOOZE modes - used in battery-powered industrial sensor nodes requiring RTC, analog sensing, and LIN communication.
For engineers reviewing the R5F104GGGFB#10 datasheet, R5F104GGGFB#10 pinout, R5F104GGGFB#10 application, or R5F104GGGFB#10 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, 12-channel 16-bit TAU timer, dual UART/LIN support, 20-channel 10-bit ADC with internal temperature sensor, and on-chip DTC/ELC for low-CPU-load peripheral coordination.
Technical Context
The R5F104GGGFB#10 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 19-source Event Link Controller (ELC) and Data Transfer Controller (DTC) to offload interrupt-driven transfers without CPU intervention.
Its mixed-signal subsystem includes a 20-channel 10-bit ADC with selectable internal reference (1.45 V) and temperature sensor, dual 8-bit DAC outputs (0–VDD), two comparators with window/high-speed/low-speed modes, and hardware LIN bus support via UART with automatic sync-break detection and checksum generation.
