Product details
Overview
R7FA2E3073CFL#BA0 from Renesas is an ultra-low-power 48 MHz Arm® Cortex®-M23 microcontroller with 64-KB code flash, 16-KB SRAM, 12-bit ADC, and integrated safety features including SRAM parity, flash protection, CAC, CRC, and IWDT - deployed in industrial sensor nodes, battery-powered HMI interfaces, and smart metering endpoints requiring functional safety compliance.
For engineers reviewing the R7FA2E3073CFL#BA0 datasheet, R7FA2E3073CFL#BA0 pinout, R7FA2E3073CFL#BA0 application, or R7FA2E3073CFL#BA0 equivalent, this page delivers verified package mapping (48-pin LQFP), confirmed pin functions (including GPT32, AGT×2, SCI×4, IIC×1, SPI×1), safety architecture details, and real-world use-case validation for design-in decisions.
Technical Context
The R7FA2E3073CFL#BA0 implements Armv8-M architecture with MPU support across 8 regions, debug via SW-DP, and dual watchdogs (WDT + independent IWDT with dedicated 15-kHz oscillator). Its clock system integrates HOCO (48 MHz), SOSC (32.768 kHz), and CAC for real-time frequency accuracy monitoring against reference clocks.
System-level peripherals include Event Link Controller (ELC) for CPU-free peripheral chaining, Data Transfer Controller (DTC) for autonomous memory transfers, and Port Output Enable for GPT (POEG) to safely disable PWM outputs during fault conditions - all operating within 1.6–5.5 V supply and -40°C to +105°C industrial temperature range.
