ATSAMV70Q19B-AABT

Overview

The ATSAMV70Q19B-AABT is a 32-bit ARM Cortex-M7 microcontroller from the SAM V70 series. It features a maximum clock frequency of 300 MHz, 512 kB of program memory, and 256 kB of SRAM. The device includes 24-channel 12-bit ADCs and 2-channel 12-bit DACs. It operates within a supply voltage range of 1.2 V to 1.32 V for the core and 3.3 V for I/O. The component supports interfaces including Ethernet AVB, USB, SPI, I2C, UART, and SDIO. It is housed in an LQFP-144 package with 114 available I/O lines.

Feature Summary

• Integrates an ARM Cortex-M7 processor core with FPU and DSP capabilities for high-performance computing.
• Includes dedicated hardware support for Audio Video Bridging (AVB) Ethernet communication.
• Provides extensive analog conversion resources with multiple 12-bit ADC and DAC channels.
• Offers flexible connectivity through various standard serial and peripheral interface controllers.

Applications

• Industrial automation systems requiring deterministic network communication
• Audio processing equipment utilizing AVB standards
• Human-machine interface panels with display and touch control requirements
• Medical devices needing precise analog signal acquisition

Procurement Notes

Verify the specific suffix AABT corresponds to the tape and reel packaging format as indicated by distributor listings. Confirm that the AEC-Q100 qualification status applies to this specific variant if automotive reliability is required. Ensure compatibility with 3.3 V logic levels for all connected peripherals. Check for moisture sensitivity level ratings prior to surface mount assembly processes.

Selection Notes

Select this model when Ethernet AVB support is mandatory alongside high-speed processing. Compare against ATSAME70 variants if automotive certification is not needed but similar pinout is desired. Consider ATSAMV71 models if larger memory capacities are required. Verify that the LQFP-144 package fits the thermal and spatial constraints of the target PCB design.

Part Context

This component belongs to the Microchip SAM V70 family, designed for applications demanding robust networking and multimedia processing. It shares architectural similarities with the SAM E70 and SAM S70 families but distinguishes itself through integrated AVB Ethernet capabilities. The series targets industrial and consumer electronics requiring synchronized audio/video transmission.

Replacement Considerations

ATSAMV70Q19A-CB offers similar specifications but may differ in packaging or qualification. ATSAME70Q19B-CFN provides comparable performance without AVB support. ATSAMV71Q21B-AABT serves as an upgrade path with increased memory capacity while maintaining the same core architecture.
