Overview
The ATSAMV71J19B-AAB is an automotive-grade microcontroller from the SAM V71 series, featuring an ARM Cortex-M7 core operating at a maximum frequency of 300 MHz. It integrates 512 kB of flash memory and 256 kB of SRAM within a 144-pin LQFP package. The device supports a supply voltage range of 1.2 V to 1.32 V for the core and 3.3 V for I/Os, with an extended operating temperature range from -40°C to +105°C. It holds AEC-Q100 qualification.
Feature Summary
- Automotive-grade reliability certified under AEC-Q100 standards for harsh environment operation
- High-performance processing via ARM Cortex-M7 core with integrated DSP and FPU capabilities
- Comprehensive connectivity suite including dual CAN FD, USB OTG, Ethernet AVB, and multiple serial interfaces
Applications
- Advanced Driver Assistance Systems (ADAS)
- In-vehicle infotainment and gateway controllers
- Instrument clusters and digital cockpit displays
- Telematics control units
Procurement Notes
Verify the specific suffix 'AAB' corresponds to the LQFP-144 packaging and standard tape-and-reel or tray availability as defined by Microchip. Confirm that the AEC-Q100 Grade 1 qualification meets the thermal requirements of the target automotive application zone. Cross-reference the latest Product Change Notice (PCN) for any recent updates to the SAM V71 series documentation or pinout definitions.
Selection Notes
Select this component when automotive certification is mandatory alongside high-speed multimedia processing. Compare against the ATSAME70 series if industrial grade suffices, or the ATSAMV71Q variant if larger memory capacities are required. Ensure the 144-pin LQFP footprint fits the board space constraints compared to BGA alternatives in the same family.
Part Context
This MCU belongs to the SAM V71 family, designed specifically for automotive applications requiring robust performance and safety features. It shares architectural similarities with the E70 and S70 families but includes specialized peripherals like Ethernet AVB and enhanced security modules tailored for vehicle networks and display interfaces.
Replacement Considerations
Direct pin-compatible replacements within the SAM V71 series include ATSAMV71J19B-CBT (BGA package) or ATSAMV71N19B variants. Verify memory size and peripheral availability matches exactly before substituting.
