Overview
The ATSAME70Q21A-ANT is a 32-bit microcontroller from the SAM E70 series, built on the ARM Cortex-M7 core. It operates at a maximum frequency of 300MHz and includes 2MB of Flash memory and 384KB of SRAM. The device features 114 I/O pins and supports interfaces including Ethernet, CAN, USB, SPI, and UART. It utilizes a 144-pin LQFP package with an operating temperature range of -40°C to +105°C.
Feature Summary
- Integrates an ARM Cortex-M7 processor with single-cycle DSP instructions and FPU for high-performance computing.
- Includes dedicated hardware security modules for secure boot and cryptographic operations.
- Features multiple communication peripherals including Ethernet MAC, CAN FD, and USB OTG.
Applications
- Industrial motor control systems
- Smart energy metering devices
- Medical equipment requiring high reliability
Procurement Notes
Verify the specific suffix 'ANT' against official Microchip documentation to confirm the tape-and-reel packaging configuration. Ensure compatibility with existing PCB footprints for the 144-LQFP package. Confirm RoHS compliance status for the specific manufacturing batch prior to integration into production lines.
Selection Notes
Select this component when a balance of high processing speed and extensive connectivity is required. The SAM E70 series offers robust peripheral sets suitable for complex applications. Compare pin counts and memory sizes against alternative models in the same family to ensure optimal fit for board space constraints.
Part Context
This MCU belongs to the SAM E70 family, designed for cost-sensitive applications requiring Cortex-M7 performance. It shares architectural similarities with the SAM S70 but typically excludes certain high-end display controllers. The series targets industrial and consumer markets needing reliable embedded control solutions.
Replacement Considerations
ATSAME70Q21A-CN serves as a tray-packaged alternative within the same electrical specification set. Verify package dimensions and thermal characteristics before substituting reel-based inventory with tray-based components.
