Product details
Overview
R5F104GCAFB#V0 from Renesas is a 48-pin LFQFP, 0.5 mm pitch, industrial-grade (G) 16-bit RL78/G14 microcontroller with 96 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 ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), targeting battery-powered industrial sensors and motor control modules.
For engineers reviewing the R5F104GCAFB#V0 datasheet, R5F104GCAFB#V0 pinout, R5F104GCAFB#V0 application, or R5F104GCAFB#V0 equivalent, key selection criteria include its integrated 10-bit 20-channel ADC, dual UART/LIN support, real-time clock with calendar, and hardware DTC/ELC for deterministic peripheral event handling in resource-constrained embedded systems.
Technical Context
The R5F104GCAFB#V0 implements the RL78 CPU core with a 3-stage pipeline, 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 12-bit interval timer, RTC with alarm/calendar, and watchdog timer driven by a dedicated low-speed oscillator.
Peripheral integration includes up to 12 × 16-bit timers (TAU, RJ, RD, RG), 4–10 I²C channels, 3–4 UART/LIN interfaces, 3–8 CSI/SPI channels, and an 8-bit DAC with real-time output capability - all configurable via Event Link Controller (ELC) for zero-CPU-overhead signal chaining.

These peripherals eliminate external components in applications like sensor signal conditioning, closed-loop control, and calibration - all fully supported in the R5F104GCAFB#V0's industrial-grade package.
How does the R5F104GCAFB#V0 manage low-power operation in battery-powered applications?
The R5F104GCAFB#V0 achieves industry-leading low-power operation with 66 μA/MHz active current and just 0.60 μA in STOP mode with RTC and LVD active. Its HALT, STOP, and SNOOZE modes, combined with programmable voltage detector (14 levels) and multiple clock sources (including 32.768 kHz crystal), enable precise power-state management. This makes the R5F104GCAFB#V0 ideal for multi-year battery life in remote sensors, where wake-on-event and sub-μA retention are essential design requirements.
