Overview
The ATSAME70Q21B-ANT-SL3 is a 32-bit microcontroller from Microchip Technology's SAM E70 series, built on the ARM Cortex-M7 core. It operates at a maximum frequency of 300 MHz and integrates 2 MB of Flash memory with 384 KB of SRAM. The device features a 144-pin LQFP package and supports a supply voltage range of 1.62 V to 3.6 V. Key peripherals include dual high-speed USB controllers, dual CAN-FD interfaces, an Ethernet MAC, and extensive I/O capabilities.
Feature Summary
- Integrates dual high-speed USB and dual CAN-FD interfaces for robust industrial communication.
- Includes an integrated Ethernet MAC for network connectivity in embedded systems.
- Features a hardware floating-point unit (FPU) and DSP instructions for complex algorithm execution.
Applications
- Industrial gateways
- Motor control systems
- Human-machine interfaces
Procurement Notes
Verify the specific suffix SL3 against official Microchip documentation to confirm its exact meaning regarding packaging or tape-and-reel specifications. Ensure compatibility with existing design files by cross-referencing the pinout and electrical characteristics with the standard ATSAME70Q21B-ANT datasheet. Confirm that the ordering code matches the required quantity format and lead time expectations provided by authorized distributors.
Selection Notes
Select this component when high computational density is required alongside multiple high-speed serial interfaces. The combination of Cortex-M7 performance with integrated Ethernet and CAN-FD makes it suitable for applications needing real-time processing and networked communication. Consider the 144-pin LQFP package constraints for PCB layout and thermal management requirements.
Part Context
This part belongs to the SAM E70 family, designed for high-performance embedded applications. It shares architectural similarities with other SAM E70 variants but offers specific memory and interface configurations tailored for industrial and automotive-grade environments requiring reliable data processing and connectivity.
Replacement Considerations
Direct substitutes within the same package and pinout include ATSAME70Q21B-AN or ATSAME70Q21B-CN. Verify memory size and peripheral availability when considering alternatives from the SAM S70 or SAM V70 families.
