ATSAMV71N21B-CBT

Overview

The ATSAMV71N21B-CBT is a high-performance microcontroller based on the 32-bit ARM Cortex-M7 processor with a floating-point unit (FPU). It operates at a maximum clock frequency of 300 MHz and includes 2 MB of Flash memory and 384 KB of SRAM. The device features an integrated Analog Front End (AFE) for sensor signal conditioning. It utilizes a TFBGA-100 package and supports automotive qualification standards.

Feature Summary

• Integrates an Analog Front End (AFE) for direct connection to sensors, reducing external component count.
• Features a high-speed 300 MHz ARM Cortex-M7 core with FPU for complex mathematical operations.
• Includes extensive connectivity interfaces such as Ethernet, USB, CAN, and multiple SPI/I2C controllers.

Applications

• Automotive instrument clusters and digital cockpit displays
• Advanced driver assistance systems (ADAS)
• Industrial motor control applications requiring precise analog sensing

Procurement Notes

Verify the specific suffix 'CBT' corresponds to the Tape and Reel packaging format in official Microchip documentation. Confirm the AEC-Q100 grade level required for your target application. Ensure the TFBGA-100 footprint matches your PCB design constraints before finalizing procurement orders.

Selection Notes

Select this model when both high computational performance and integrated analog front-end capabilities are required. It is suitable for designs needing to interface directly with piezoelectric or capacitive sensors without additional discrete signal conditioning circuitry. Compare against the ATSAMV71Q series if a larger pin count or different package type is necessary.

Part Context

This component belongs to the SAM V71 family of microcontrollers designed for automotive and industrial markets. It shares the same core architecture as other V71 variants but distinguishes itself through the inclusion of the dedicated AFE peripheral and specific memory configuration within a compact 100-pin package.

Replacement Considerations

Direct substitutes include other members of the SAM V71 family such as the ATSAMV71Q21B series, provided the package and pinout compatibility are verified. Cross-referencing the specific AFE requirements is essential when considering alternatives from different manufacturers.
