Product details
Overview
R5F104MGDFB#X0 from Renesas is a 80-pin LFQFP, 0.5 mm pitch, industrial-grade (TA = −40 to +105°C) RL78/G14 16-bit MCU with 96 KB flash, 8 KB data flash, 12 KB RAM, and integrated RTC, 10-bit ADC (19 channels), and UART/SPI/I²C interfaces. It targets battery-powered industrial sensors and low-power HMI control units.
For engineers reviewing the R5F104MGDFB#X0 datasheet, R5F104MGDFB#X0 pinout, R5F104MGDFB#X0 application, or R5F104MGDFB#X0 equivalent, key selection criteria include its 0.60 μA STOP-mode current, 66 μA/MHz active power, 44 DMIPS @ 32 MHz performance, and support for background data flash rewriting (1M write cycles).
Technical Context
The R5F104MGDFB#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (@32 MHz) to 30.5 μs (@32.768 kHz). It integrates an Event Link Controller (ELC) for hardware-triggered peripheral chaining and a Data Transfer Controller (DTC) enabling interrupt-driven memory transfers without CPU intervention.
Its clock system includes a high-accuracy ±1.0% on-chip oscillator (selectable from 1–64 MHz), dedicated low-speed oscillator for watchdog/RTC, and external crystal support (X1/X2, XT1/XT2). Power management features HALT, STOP, and SNOOZE modes with configurable voltage detector (LVD) and POR circuitry.
