Product details
Overview
R5F104AEGSP#V0 from Renesas is a 32-bit RL78/G14 microcontroller with 48 KB flash memory, 5.5 KB RAM, and 40-pin LSSOP package (0.65 mm pitch), operating from 1.6 V to 5.5 V. It delivers 44 DMIPS at 32 MHz, features an ultra-low-power HALT/STOP/SNOOZE mode (0.60 μA RTC+LVD), and integrates 10-bit ADC (16 channels), UART/SPI/I²C interfaces, and real-time clock for embedded control in battery-powered industrial sensors.
For engineers reviewing the R5F104AEGSP#V0 datasheet, R5F104AEGSP#V0 pinout, R5F104AEGSP#V0 application, or R5F104AEGSP#V0 equivalent, key selection criteria include its 40-pin LSSOP footprint, -40°C to +85°C industrial-grade temperature range (A-grade), 48 KB code flash with self-programming, and integrated analog peripherals enabling compact, low-power sensor node designs without external timing or signal conditioning.
Technical Context
The R5F104AEGSP#V0 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 embeds a high-accuracy ±1.0% on-chip oscillator (1–64 MHz selectable) and hardware event link controller (ELC) for deterministic peripheral triggering without CPU intervention.
Its power management includes on-chip POR and 14-level voltage detector (LVD) with interrupt/reset options, while the Data Transfer Controller (DTC) enables background data flash rewriting (1M write cycles, 1.8–5.5 V) concurrent with program execution-critical for firmware-over-the-air updates in field-deployed devices.
