Overview
The ATSAMV71N20B-CB is an automotive-grade microcontroller from the SAM V71 series, built on a 32-bit ARM Cortex-M7 core with a floating-point unit. It features 1 MB of Flash memory and 384 kB of SRAM, operating at a maximum frequency of 300 MHz. The device supports a supply voltage range of 1.2 V to 1.32 V for the core and includes 75 I/O pins. Key peripherals include Ethernet AVB, CAN, USB, SPI, UART, USART, I2S, ISI, SD interfaces, along with 10-channel 12-bit ADCs and 12-bit DACs. It is housed in a TFBGA-100 package and certified to AEC-Q100 standards.
Feature Summary
- Automotive-grade reliability compliant with AEC-Q100 standards
- Integrated Ethernet Audio Video Bridging (AVB) support
- High-performance ARM Cortex-M7 processor with FPU
- Comprehensive connectivity including CAN, USB, and SD interfaces
Applications
- Advanced Driver Assistance Systems (ADAS)
- In-Vehicle Infotainment (IVI) systems
- Digital instrument clusters
- Telematics control units
Procurement Notes
Verify the exact suffix against official Microchip documentation, as 'CB' may denote specific packaging or temperature variants. Confirm AEC-Q100 qualification status for your target automotive application. Ensure design compatibility with the TFBGA-100 footprint and 1.2V core voltage requirements during schematic capture.
Selection Notes
Select this component when automotive certification and high-speed multimedia processing are required. Compare against other SAM V71 variants based on memory size and pin count if fewer I/Os suffice. Consider the ATSAME70 series for non-automotive applications requiring similar performance without AEC-Q100 constraints.
Part Context
This part belongs to the SAM V71 family, designed specifically for demanding automotive environments. It shares architectural similarities with the SAM E70 and SAM S70 series but distinguishes itself through rigorous automotive quality controls and specialized connectivity features like Ethernet AVB for audio/video streaming.
Replacement Considerations
Consult Microchip's official cross-reference tools for qualified alternatives. Verify that any substitute maintains AEC-Q100 compliance and compatible pinout if direct replacement is intended.
