Product details
Overview
R5F104PFGFA#10 from Renesas is a 100-pin LQFP, 5.5-V, 32-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and integrated 10-bit ADC (16-channel), UART/LIN, I²C, and RTC - deployed in industrial motor control and sensor interface modules requiring low-power operation at -40°C to +85°C.
For engineers reviewing the R5F104PFGFA#10 datasheet, R5F104PFGFA#10 pinout, R5F104PFGFA#10 application, or R5F104PFGFA#10 equivalent, key selection criteria include its 96 KB code flash size, 100-pin LQFP-0.65 mm pitch package, 16-channel 10-bit ADC, LIN-capable UART, and support for STOP/HALT/SNOOZE ultra-low-power modes.
Technical Context
The R5F104PFGFA#10 implements the RL78 CPU core with 3-stage pipeline CISC architecture, enabling instruction execution times from 0.03125 µs (@32 MHz) to 30.5 µs (@32.768 kHz), and supports multiply/divide/accumulate operations within a 1 MB address space. It integrates a Data Transfer Controller (DTC) and Event Link Controller (ELC) for autonomous peripheral coordination without CPU intervention.
Its power management includes on-chip POR, 14-level LVD with interrupt/reset options, and true low-power operation: 66 μA/MHz active current and 0.60 μA in RTC+LVD-only STOP mode. The high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) eliminates external crystal dependency for many timing-critical applications.
