Product details
Overview
R5F104GAAFB#V0 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (−40°C to +105°C) RL78/G14 16-bit microcontroller with 128 KB flash, 12 KB RAM, and 8 KB data flash. 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 power for battery-sensitive embedded control.
For engineers reviewing the R5F104GAAFB#V0 datasheet, R5F104GAAFB#V0 pinout, R5F104GAAFB#V0 application, or R5F104GAAFB#V0 equivalent, key selection considerations include its integrated 10-bit 20-channel ADC, dual UART/LIN support, real-time clock with calendar, hardware DTC/ELC peripherals, and low-voltage operation down to 1.6 V in industrial temperature environments.
Technical Context
The R5F104GAAFB#V0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz high-speed mode) to 30.5 μs (32.768 kHz ultra-low-speed mode). It integrates a configurable Event Link Controller (ELC) enabling direct peripheral-to-peripheral event triggering without CPU intervention.
Its power management includes HALT, STOP, and SNOOZE modes, on-chip POR and 14-level LVD, and a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable). The device supports background operation (BGO) for data flash rewriting while executing code from program memory.
