Overview
The ATSAME70Q20B-CN is a 32-bit microcontroller from the Microchip SAM E70 series, featuring an ARM Cortex-M7 core operating at 300 MHz. It integrates 1 MB of flash memory and 384 KB of SRAM within a 144-LQFP package. The device supports a supply voltage range of 1.62 V to 3.6 V and operates between -40°C and +105°C. Connectivity options include Ethernet, USB, CANbus, I2C, SPI, UART/USART, QSPI, MMC/SD/SDIO, LINbus, IrDA, and EBI/EMI interfaces.
Feature Summary
- High-performance processing via ARM Cortex-M7 core with DSP instructions
- Integrated connectivity supporting Ethernet, USB, and multiple serial protocols
- Flexible external bus interface for parallel peripheral expansion
- Comprehensive analog subsystem with multiple ADCs and DACs
Applications
- Industrial automation controllers
- Medical devices requiring high-speed data acquisition
- Infotainment systems and HMI displays
- Smart metering applications
Procurement Notes
Verify the specific suffix 'CN' against the manufacturer's official datasheet to confirm regional compliance or material specifications. Ensure the 144-LQFP package dimensions match the target PCB footprint. Confirm that the selected development tools support the SAM E70 architecture for firmware deployment.
Selection Notes
Select this component when a balance of high computational throughput and extensive peripheral integration is required. The 1 MB flash capacity suits complex application logic, while the Cortex-M7 core handles signal processing tasks. Consider alternative pin counts if fewer I/O connections are needed or if cost constraints require lower memory configurations within the same family.
Part Context
This part belongs to the SAM E70 family, designed for performance-oriented embedded applications. It shares architectural similarities with the S70 and V71 series but offers distinct memory and peripheral configurations tailored for cost-sensitive yet powerful control solutions.
Replacement Considerations
ATSAME70Q20A-AN provides equivalent functionality in a 144-LQFP package. ATSAME70Q20A-CFNT offers the same core specifications in a 144-UFBGA package.
