Product details
Overview
R5F104GGGNA#20 from Renesas is a 48-pin LFQFP, 128 KB flash, 12 KB RAM RL78/G14 16-bit MCU operating from 1.6–5.5 V, delivering 44 DMIPS at 32 MHz with true low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD mode), used in industrial sensor nodes and battery-powered control modules.
For engineers reviewing the R5F104GGGNA#20 datasheet, R5F104GGGNA#20 pinout, R5F104GGGNA#20 application, or R5F104GGGNA#20 equivalent, key selection criteria include its -40°C to +105°C industrial-grade temperature rating (G suffix), integrated 10-bit 16-channel ADC, dual UART/LIN support, and hardware DTC/ELC for deterministic real-time peripheral coordination.
Technical Context
The R5F104GGGNA#20 implements the RL78 CPU core with 3-stage CISC pipeline, supporting instruction execution times from 0.03125 µs (32 MHz high-speed oscillator) to 30.5 µs (32.768 kHz subsystem clock), and includes multiply/divide/accumulate instructions within a 1 MB address space.
It integrates a Data Transfer Controller (DTC) with chain transfer capability and an Event Link Controller (ELC) enabling direct hardware linking of up to 26 event sources to peripherals-eliminating CPU intervention for time-critical signal routing in motor control and power management systems.
