Product details
Overview
R5F104JEGFA#V0 from Renesas is a 52-pin LQFP-0.65mm, 256 KB flash, 8 KB data flash, 20 KB RAM RL78/G14 16-bit microcontroller operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with ultra-low power consumption (66 μA/MHz active, 0.60 μA RTC+LVD mode), used in battery-powered industrial sensor nodes and smart metering interfaces.
For engineers reviewing the R5F104JEGFA#V0 datasheet, R5F104JEGFA#V0 pinout, R5F104JEGFA#V0 application, or R5F104JEGFA#V0 equivalent, key selection criteria include its 52-pin LQFP package, integrated RTC with calendar/alarm, dual UART/LIN support, 10-bit 16-channel ADC, and hardware DTC/ELC for deterministic low-power peripheral coordination.
Technical Context
The R5F104JEGFA#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 within a 1 MB address space. It integrates a high-accuracy ±1.0% on-chip oscillator (selectable 1–64 MHz) and dedicated low-speed oscillator for watchdog operation.
Peripheral subsystems include an Event Link Controller (ELC) enabling 19–26 event sources to trigger peripheral functions without CPU intervention, and a Data Transfer Controller (DTC) supporting normal, repeat, block, and chain transfer modes activated by interrupts - both critical for deterministic real-time response in energy-constrained applications.
