概述

Description

ATSAM3X4EA-CU is a 32‑bit ARM Cortex‑M3 microcontroller from Atmel (now Microchip) in the SAM3X family. It targets embedded control and USB‑enabled applications with a rich peripheral set and efficient power management.
Key points:
- Core and performance: ARM Cortex‑M3, up to about 84 MHz.
- Memory: on‑chip flash and SRAM (sizes vary by device variant).
- Peripherals: multiple USARTs, SPI, I2C/TWI, USB OTG Full‑Speed, ADCs, DACs, timers/PWM, DMA, and a memory‑protection unit; NVIC for interrupts.
- Development: supported by Atmel Studio or Microchip MPLAB X, GCC toolchain, and ASF/Driver libraries.
- Packaging: CU denotes a specific package/revision; check the datasheet for exact pin count and dimensions.
- Applications: USB devices, data acquisition, motor/control applications, and other embedded controllers.
For exact clock speeds, memory sizes, peripheral counts, and packaging details, consult the ATSAM3X4EA-CU datasheet and product page.
