Product details
Overview
R7FA2E3073CFJ#BA0 from Renesas Electronics is an ultra-low-power 32-bit Arm® Cortex®-M23 microcontroller operating at up to 48 MHz, featuring 64-KB code flash, 16-KB SRAM, a 12-bit ADC with 13 input channels, and integrated safety functions including SRAM parity, flash protection, and CAC for clock accuracy monitoring - deployed in industrial sensor nodes and battery-powered HMI interfaces.
For engineers reviewing the R7FA2E3073CFJ#BA0 datasheet, R7FA2E3073CFJ#BA0 pinout, R7FA2E3073CFJ#BA0 application, or R7FA2E3073CFJ#BA0 equivalent, key selection criteria include its 32-pin LQFP package, -40°C to +105°C industrial temperature grade, 1.6–5.5 V wide supply range, dual watchdog timers (WDT/IWDT), and hardware safety accelerators (CRC, DOC, AGT) supporting IEC 61508-compliant system design.
Technical Context
The R7FA2E3073CFJ#BA0 implements the Armv8-M architecture with Memory Protection Unit (MPU) supporting eight regions, enabling secure partitioning of firmware and data. Its clock system integrates multiple oscillators - HOCO (48 MHz), SOSC (32.768 kHz), and LOCO - with trimmable frequency accuracy and dedicated IWDT oscillator for fail-safe reset.
Peripheral integration includes four SCI modules (supporting UART, SPI, I²C, and smart card modes), one dedicated I²C bus interface, one SPI channel, two AGT timers for low-power event counting, and GPT16 × 6 channels with POEG output enable for BLDC motor control - all coordinated via Event Link Controller (ELC) to minimize CPU intervention.
