Product details
Overview
R5F104LDDFB#X0 from Renesas is a 64-pin LFQFP, 0.5 mm pitch, industrial-grade (D) 16-bit RL78/G14 microcontroller with 32 KB flash, 4 KB data flash, and 4 KB RAM, operating from 1.6–5.5 V at -40 to +85°C, delivering 44 DMIPS at 32 MHz for low-power sensor interface and motor control applications.
For engineers reviewing the R5F104LDDFB#X0 datasheet, R5F104LDDFB#X0 pinout, R5F104LDDFB#X0 application, or R5F104LDDFB#X0 equivalent, this page provides verified package mapping, confirmed peripheral allocation (12× 16-bit timers, 8-channel 10-bit ADC, UART/SPI/I²C), real-time clock with calendar, and ultra-low-power HALT/STOP/SNOOZE modes - all validated for industrial embedded design.
Technical Context
The R5F104LDDFB#X0 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 RTC mode). It integrates a Data Transfer Controller (DTC) with chain transfer and an Event Link Controller (ELC) enabling direct peripheral-to-peripheral event routing without CPU intervention.
Its power management includes on-chip POR and LVD with 14 selectable voltage detection levels, while the high-accuracy ±1.0% on-chip oscillator supports 12 frequency options from 1 to 64 MHz - eliminating external crystal dependency in cost-sensitive designs.
