ATSAMV71N19B-AABT

Overview

The ATSAMV71N19B-AABT is an ARM-based microcontroller from the SAM V71 series, manufactured by Microchip Technology. It features a 32-bit ARM Cortex-M7 processor core operating at a maximum clock frequency of 300 MHz. The device integrates 512 kB of Flash memory and 256 kB of SRAM. It is housed in a TFBGA-100 package with 75 I/O lines. Key peripherals include a 12-bit ADC with 10 channels, a 12-bit DAC, and multiple communication interfaces such as SPI, UART, USART, and USB.

Feature Summary

• High-performance processing capability enabled by the ARM Cortex-M7 core with floating-point unit
• Integrated analog-to-digital conversion with dedicated internal temperature sensor channel
• Support for automotive applications through compliance with ISO-TS-16949 manufacturing standards
• Flexible connectivity via multiple serial communication protocols including USB and SSC

Applications

• Automotive infotainment systems
• Industrial control panels
• Medical devices requiring high-speed data processing
• Human-machine interface (HMI) displays

Procurement Notes

Verify the specific suffix 'AABT' against official Microchip documentation to confirm tape-and-reel packaging and exact pinout configuration. Ensure compatibility with required operating voltage ranges and thermal specifications for the target application environment. Cross-reference the datasheet revision date to guarantee access to the latest errata and design recommendations.

Selection Notes

Select this component when a balance of moderate memory capacity and high processing speed is required within a compact 100-pin footprint. It is suitable for designs needing integrated analog peripherals without external converters. Consider alternative packages like LQFP if surface-mount BGA assembly capabilities are unavailable or if cost constraints favor leaded packages.

Part Context

This MCU belongs to the SAM V71 family, designed for high-performance embedded applications. The family shares common architectural features but varies in memory size and package options. The N19 variant specifically denotes the 512 kB Flash and 256 kB SRAM configuration, distinguishing it from higher-capacity models like the Q21.

Replacement Considerations

ATSAMV71N19B-CBT: Different package type (TFBGA vs unspecified in snippet, likely similar form factor but verify pinout). ATSAMS70N19A-AN: Similar specs but different series (S70 vs V71), potentially different peripheral sets.
