Product details
Overview
R5F104GDDFB#X0 from Renesas is a 48-pin LFQFP, industrial-grade (TA = −40 to +105°C) RL78/G14 16-bit MCU with 128 KB flash, 12 KB RAM, and 8 KB data flash-designed for low-power embedded control in motor drives, sensor nodes, and industrial HMI. It delivers 44 DMIPS at 32 MHz, operates from 1.6–5.5 V, and achieves 66 μA/MHz active current and 0.60 μA RTC+LVD standby.
For engineers reviewing the R5F104GDDFB#X0 datasheet, R5F104GDDFB#X0 pinout, R5F104GDDFB#X0 application, or R5F104GDDFB#X0 equivalent, key selection criteria include its 48-pin LFQFP-0.5 mm package, integrated 10-bit 20-channel ADC, dual UART/LIN support, and hardware DTC/ELC for deterministic real-time peripheral coordination.
Technical Context
The R5F104GDDFB#X0 implements the RL78 CPU core-a CISC architecture with 3-stage pipeline, supporting instruction execution times from 0.03125 µs (32 MHz) to 30.5 µs (32.768 kHz). 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 mixed-signal subsystem includes a 10-bit A/D converter with internal 1.45 V reference and temperature sensor, two 8-bit D/A channels with real-time output, and dual comparators configurable in high-speed, low-speed, or window mode-all operating across the full 1.6–5.5 V supply range.
