Overview
The ATSAME70N21A-AN is a 32-bit microcontroller from the SAM E70 series, featuring an ARM Cortex-M7 core operating at 300MHz. It integrates 2MB of flash memory and 384KB of SRAM within a 100-LQFP package. The device supports a supply voltage range of 1.62V to 3.6V and operates between -40°C and 105°C. Connectivity includes Ethernet, CANbus, I2C, SPI, UART/USART, USB, QSPI, and MMC/SD/SDIO interfaces. Peripherals comprise DMA, I2S, PWM, WDT, and power-on reset.
Feature Summary
- High-performance processing via ARM Cortex-M7 core with integrated FPU for complex control algorithms
- Integrated Ethernet MAC with dedicated DMA for robust network communication capabilities
- Comprehensive peripheral set including multiple serial interfaces and high-speed data converters
Applications
- Industrial motor control systems requiring precise timing and connectivity
- Human-machine interface (HMI) panels with graphical display requirements
- Smart energy metering devices needing secure data transmission
Procurement Notes
Verify the specific suffix 'AN' corresponds to the 100-LQFP tray packaging configuration as documented in official Microchip datasheets. Confirm that the required operating temperature range and voltage specifications align with your system design constraints before finalizing procurement orders.
Selection Notes
Select this component when a balance of high computational performance and extensive connectivity is required. The 2MB flash capacity supports complex firmware and large graphics buffers. Ensure the 100-pin LQFP footprint fits the PCB layout constraints compared to BGA alternatives in the same family.
Part Context
This part belongs to the SAM E70 family, designed for applications demanding high performance and rich connectivity. It shares architectural similarities with the SAM S70 but targets different market segments. The N21 variant specifically denotes the 2MB flash configuration within the LQFP package option.
Replacement Considerations
ATSAME70N21A-CN offers identical electrical specifications in a TFBGA package. ATSAMS70N21A-ANT provides the same core functionality in tape-and-reel packaging.
