Product details
Overview
R5F104GGGNA#W0 from Renesas is a 48-pin HWQFN-packaged 16-bit RL78/G14 microcontroller with 128 KB flash, 12 KB RAM, and 8 KB data flash, operating from 1.6–5.5 V at -40 to +105°C (industrial G-grade). It delivers 44 DMIPS at 32 MHz, features ultra-low-power operation (66 μA/MHz active, 0.60 μA RTC+LVD), and integrates UART, I²C, SPI, 16-bit timers, 10-bit ADC (16 ch), and real-time clock for embedded control in industrial sensors and motor drives.
For engineers reviewing the R5F104GGGNA#W0 datasheet, R5F104GGGNA#W0 pinout, R5F104GGGNA#W0 application, or R5F104GGGNA#W0 equivalent, key selection criteria include its 48-pin HWQFN (7×7 mm, 0.5 mm pitch) package, industrial temperature rating, integrated data flash with 1M rewrite cycles, and support for SNOOZE mode for low-latency wake-up in battery-powered systems.
Technical Context
The R5F104GGGNA#W0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed oscillator) to 30.5 μs (32.768 kHz subsystem clock). It includes on-chip debug, self-programming with boot swap, and flash shield window security.
Its peripheral set includes 16-bit Timer Array Unit (TAU) with up to 8 channels, 12-bit interval timer, calendar RTC with alarm/correction, watchdog timer, and Event Link Controller (ELC) enabling hardware-triggered peripheral chaining without CPU intervention-critical for deterministic real-time response in industrial automation.
