Product details
Overview
R5F104JGGFA#V0 from Renesas is a 52-pin LQFP-0.65mm industrial-grade RL78/G14 16-bit microcontroller with 256 KB flash, 12 KB RAM, and 20-channel 10-bit ADC, designed for battery-powered sensor nodes and motor control in HVAC and industrial automation systems.
For engineers reviewing the R5F104JGGFA#V0 datasheet, R5F104JGGFA#V0 pinout, R5F104JGGFA#V0 application, or R5F104JGGFA#V0 equivalent, key selection criteria include its 1.6–5.5 V operation range, 66 μA/MHz active current, RTC + LVD ultra-low-power STOP mode (0.60 μA), and integrated UART/LIN, I²C, and SPI interfaces for embedded control.
Technical Context
The R5F104JGGFA#V0 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), and includes multiply/divide/accumulate instructions with 1 MB address space.
It integrates dual-clock domain operation: high-speed on-chip oscillator (selectable 1–64 MHz, ±1.0% accuracy) for main system timing and dedicated low-speed oscillator for watchdog and RTC, enabling deterministic real-time response while minimizing power in mixed-mode applications.
