Product details
Overview
R5F104LDGFA#30 from Renesas is a 64-pin LFQFP, 0.5 mm pitch, industrial-grade (−40°C to +105°C) RL78/G14 16-bit MCU with 32 KB flash, 4 KB data flash, 4 KB RAM, 32 MHz max CPU speed, and integrated 10-bit ADC (16 channels), UART (3 ch), I²C (4 ch), and 12-bit RTC. It targets low-power sensor nodes and industrial control interfaces.
For engineers reviewing the R5F104LDGFA#30 datasheet, R5F104LDGFA#30 pinout, R5F104LDGFA#30 application, or R5F104LDGFA#30 equivalent, key selection criteria include its −40°C to +105°C operating range, 32 KB code flash with self-programming support, 4 KB data flash with 1M rewrite cycles, 16-channel 10-bit ADC, and LFQFP-64 (10 × 10 mm) package compatibility with high-density industrial PCB layouts.
Technical Context
The R5F104LDGFA#30 implements the RL78 CPU core with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz), and includes on-chip debug, BGO-capable data flash, and event-link controller for peripheral-triggered operations without CPU intervention.
It integrates a 12-bit interval timer, real-time clock with calendar/alarm, watchdog timer, and voltage detector (LVD) with 14 selectable levels - all operating within 1.6–5.5 V supply range and optimized for ultra-low power: 66 µA/MHz active, 0.60 µA in RTC+LVD-only STOP mode.
