Overview
The ATSAME70N19A-ANT is a 32-bit microcontroller based on the ARM Cortex-M7 core, operating at a maximum frequency of 300 MHz. It features 512 kB of Flash memory and 256 kB of SRAM within a 64-LQFP package. The device supports a supply voltage range of 1.62 V to 3.6 V and includes interfaces such as USB, SPI, UART, USART, I2C, CANbus, Ethernet, and SDIO. It integrates ten 12-bit ADC channels and two 12-bit DACs, with an operating temperature range from -40°C to +105°C.
Feature Summary
- High-performance processing via ARM Cortex-M7 core with integrated FPU for complex mathematical operations
- Comprehensive connectivity suite including Ethernet MAC, USB OTG, and multiple serial communication peripherals
- Integrated analog subsystem with high-resolution ADC and DAC converters for signal processing tasks
Applications
- Industrial automation controllers requiring deterministic real-time performance
- Human-machine interface (HMI) panels with graphical display capabilities
- Smart energy metering systems utilizing precise analog measurement features
Procurement Notes
Verify the specific suffix 'ANT' indicates tape and reel packaging when sourcing components. Confirm that the 64-pin LQFP footprint matches the target PCB layout constraints. Ensure compatibility with the 1.62V to 3.6V power domain requirements for both core and I/O voltages during system design validation.
Selection Notes
Select this component for designs demanding high-speed execution alongside robust peripheral integration. The 512 kB Flash capacity suits applications with substantial firmware requirements. Consider the 64-pin form factor for space-constrained boards where fewer pins are needed compared to the 100-pin variants in the same family.
Part Context
This part belongs to the SAM E70 series, which targets high-performance embedded applications. It shares architectural similarities with the SAM S70 but lacks certain advanced security or specific peripheral configurations found in other variants. The device is designed for environments requiring reliable operation across wide industrial temperature ranges.
Replacement Considerations
ATSAME70N19A-AN serves as a tray-packaged alternative with identical electrical characteristics. ATSAMS70N19A-ANT offers similar specifications but may include different security features or peripheral sets; verify datasheet details before substitution.
