Product details
Overview
R5F104FEDFP#X0 from Renesas is a 44-pin LQFP-44, 96 KB flash, 12 KB RAM RL78/G14 16-bit microcontroller with ultra-low-power operation (66 μA/MHz), 32 MHz max CPU speed, integrated 10-bit ADC (20-channel), and real-time clock. It targets battery-powered industrial sensors and smart metering interfaces requiring low-voltage operation (1.6–5.5 V) and long-term RTC+LVD retention (0.60 μA).
For engineers reviewing the R5F104FEDFP#X0 datasheet, R5F104FEDFP#X0 pinout, R5F104FEDFP#X0 application, or R5F104FEDFP#X0 equivalent, key selection criteria include its 44-pin LQFP-0.8 mm pitch package, 96 KB code flash with data flash (8 KB), 12 KB RAM, dual UART/LIN support, and industrial-grade temperature range (−40°C to +85°C).
Technical Context
The R5F104FEDFP#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 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 a 10-bit A/D converter with internal reference (1.45 V) and temperature sensor, dual 8-bit D/A channels with real-time output, and two analog comparators with window mode. Power management features HALT, STOP, and SNOOZE modes, plus on-chip LVD with 14 selectable voltage thresholds and POR circuitry.
