Product details
Overview
R5F104BGAFP#X0 from Renesas is a 32-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 44-pin LQFP-0.8 mm package, operating from 1.6–5.5 V at -40 to +85°C (industrial grade D). It delivers 44 DMIPS at 32 MHz, features ultra-low power consumption (66 μA/MHz active, 0.60 μA in RTC+LVD mode), and integrates 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and real-time clock for embedded control applications.
For engineers reviewing the R5F104BGAFP#X0 datasheet, R5F104BGAFP#X0 pinout, R5F104BGAFP#X0 application, or R5F104BGAFP#X0 equivalent, key selection criteria include industrial temperature support, integrated data flash (8 KB), low-power sleep modes (HALT/STOP/SNOOZE), and peripheral flexibility via Event Link Controller (ELC) and Data Transfer Controller (DTC).
Technical Context
The R5F104BGAFP#X0 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 includes multiply/divide/accumulate instructions and 1 MB address space.
Its mixed-signal integration includes an 8/10-bit ADC with internal 1.45 V reference and temperature sensor, dual-channel 8-bit DAC with real-time output, two comparators, and programmable voltage detector (LVD) with 14 interrupt/reset levels - all optimized for sensor interfacing and closed-loop control in resource-constrained systems.
