Product details
Overview
R5F104BEGFP#X0 from Renesas is a 32-bit RL78/G14 microcontroller with 96 KB flash, 12 KB RAM, and 48-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 UART, I²C, SPI, 12-bit ADC (16 ch), RTC, and hardware DTC/ELC for sensor and control applications.
For engineers reviewing the R5F104BEGFP#X0 datasheet, R5F104BEGFP#X0 pinout, R5F104BEGFP#X0 application, or R5F104BEGFP#X0 equivalent, key selection criteria include industrial temperature support, integrated data flash (8 KB), low-power real-time clock operation, and peripheral flexibility via ELC event linking and DTC background transfers.
Technical Context
The R5F104BEGFP#X0 implements the RL78 CPU core with 3-stage pipeline CISC architecture, supporting instruction execution times from 0.03125 μs (32 MHz) to 30.5 μs (32.768 kHz). It uses on-chip high-accuracy oscillator (±1.0% over -20 to +85°C) and supports multiple low-power modes: HALT, STOP, and SNOOZE.
Peripheral integration includes Timer Array Unit (TAU) with 8 channels, 12-bit interval timer, real-time clock with calendar/alarm, 8-bit DAC (2 ch), two comparators, and up to 10-channel I²C/SPI/UART interfaces-all configurable via Event Link Controller (ELC) for deterministic, interrupt-free peripheral chaining without CPU intervention.
