Product details
Overview
R7FA2E1A72DFL#BA0 from Renesas is an Arm® Cortex®-M23 microcontroller operating at up to 32 MHz, featuring 64-KB code flash, 12-KB SRAM, a 12-bit ADC with 10 input channels, serial interfaces (SAU × 6, UARTA × 1, IICA × 1), and safety features including SRAM parity, CRC, IWDT, and ADC self-diagnosis - deployed in industrial sensor nodes requiring low-power, functional safety, and secure firmware updates.
For engineers reviewing the R7FA2E1A72DFL#BA0 datasheet, R7FA2E1A72DFL#BA0 pinout, R7FA2E1A72DFL#BA0 application, or R7FA2E1A72DFL#BA0 equivalent, key selection criteria include its 32-pin LQFP package, -40°C to +105°C extended temperature rating, 1.6–5.5 V wide supply range, integrated TRNG for secure boot, and hardware-based flash area protection for certified firmware integrity.
Technical Context
The R7FA2E1A72DFL#BA0 implements the Armv8-M architecture with TrustZone®-M support, enabling secure partitioning of trusted and non-trusted code execution. Its memory subsystem includes 64-KB code flash with read protection (FRP), 1-KB data flash rated for 1 million program/erase cycles, and 12-KB parity-protected SRAM for error detection.
Peripherals are tightly coupled via the Event Link Controller (ELC) and Data Transfer Controller (DTC), allowing autonomous peripheral-to-peripheral triggering and DMA transfers without CPU intervention - critical for deterministic real-time response in motor control and sensor fusion applications.
