Description

ATSAM3S4CA-AU is an Atmel/Microchip 32‑bit microcontroller from the SAM3S family, built on an ARM Cortex‑M3 core. It is designed for mid‑range embedded apps needing USB connectivity and real‑time control.
Key points:
- Core: ARM Cortex‑M3 (32‑bit, deterministic real‑time performance).
- Memory: on‑chip flash and RAM (sizes vary by the specific variant).
- Peripherals: USB Full‑Speed device, multiple serial interfaces (USART/UART, SPI, I2C), timers, PWM, ADC (and supporting DMA), RTC, and watchdog features.
- Package: AU suffix denotes a specific package type/temperature range; check the datasheet for exact pinout and package details.
- Development: supported by Atmel Studio, CMSIS, and GCC toolchains.
Applications range from USB devices and consumer electronics to industrial control. For exact specs (clock speed, RAM/Flash sizes, pin count), consult the ATSAM3S4CA‑AU datasheet and product page.
