Product details
Overview
R7FA2E3073CFL#AA0 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, and smart metering endpoints.
For engineers reviewing the R7FA2E3073CFL#AA0 datasheet, R7FA2E3073CFL#AA0 pinout, R7FA2E3073CFL#AA0 application, or R7FA2E3073CFL#AA0 equivalent, this page delivers verified package mapping (48-pin LQFP), confirmed pin functions (e.g., GTIOCnA/B for PWM, AGTIO0/1 for event timing), safety-critical peripheral enablement (IWDT, DOC, register write protection), and real-world design constraints (1.6–5.5 V operation, -40°C to +105°C).
Technical Context
The R7FA2E3073CFL#AA0 implements Armv8-M architecture with MPU (8 regions), DWT/FPB debug, and SW-DP interface. Its clock system integrates HOCO (48 MHz), SOSC (32.768 kHz), and IWDT-dedicated 15 kHz oscillator, enabling precise frequency accuracy measurement via CAC using external reference input on CACREF.
System-level safety is enforced through hardware-assisted mechanisms: SRAM parity error detection triggers reset, flash area protection prevents unauthorized writes, ADC self-diagnosis validates analog path integrity, and POEG disables GPT outputs during fault conditions - all operating without CPU intervention via ELC-triggered responses.
