ATSAMV70Q20B-AABT

Overview

The ATSAMV70Q20B-AABT is an ARM microcontroller from the SAM V70 series, featuring a Cortex-M7 core with FPU and DSP capabilities. It operates at a maximum clock frequency of 300 MHz and includes 1 MB of Flash memory and 384 kB of SRAM. The device provides 114 I/O pins and supports multiple interfaces including Ethernet AVB, CAN-FD, USB OTG, SDIO, SPI, UART, and I2C. It features 24-channel 12-bit ADCs and 12-bit DACs. Operating voltage ranges from 1.2 V to 1.32 V for the core and 3.3 V analog supply. It is housed in a 144-pin LQFP package and certified to AEC-Q100 standards for automotive applications.

Feature Summary

• Integrated Ethernet Audio Video Bridging (AVB) support for high-performance networking
• Automotive-grade reliability with AEC-Q100 qualification
• High-speed processing via Cortex-M7 core with hardware floating-point unit
• Comprehensive connectivity suite including CAN-FD and USB On-The-Go

Applications

• Automotive infotainment systems
• Advanced driver assistance systems (ADAS)
• Industrial motor control
• Smart home gateways

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 is required for your specific automotive application tier. Ensure compatibility with 3.3V logic levels for all peripheral connections. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when automotive certification and Ethernet AVB are mandatory. Compare against the ATSAMS70Q20B-CN if industrial temperature range suffices and BGA packaging is preferred. Consider the ATSAMV71Q21B-AABT if larger memory capacity is needed. Verify pinout compatibility with existing designs due to the LQFP-144 form factor constraints.

Part Context

This part belongs to the Microchip SAM V70 family, designed for high-performance embedded applications requiring robust connectivity and processing power. The V70 series distinguishes itself with integrated Ethernet AVB capabilities, making it suitable for audio/video streaming and networked control systems. It bridges the gap between general-purpose MCUs and application processors in cost-sensitive automotive and industrial segments.

Replacement Considerations

ATSAMV70Q20B-CBT is available in tray packaging instead of reel. ATSAMS70Q20B-CN offers similar specs but uses LFBGA-144 packaging and lacks explicit AVB documentation in some listings.
