ATSAMS70Q19B-CNT

Overview

The ATSAMS70Q19B-CNT is a 32-bit ARM Cortex-M7 microcontroller from the SAM S70 family, operating at a maximum clock frequency of 300 MHz. It features 512 kB of Flash memory and 256 kB of SRAM within a 144-pin LFBGA package. The device includes an Analog Front End (AFE) with 24-channel 12-bit ADCs and dual 12-bit DACs. It supports CAN-FD interfaces and offers 114 general-purpose I/O pins. Operating voltage ranges from 1.7 V to 3.6 V, with a functional temperature range of -40°C to +105°C.

Feature Summary

• Integrated Analog Front End (AFE) supporting high-precision signal acquisition via multiple 12-bit ADC channels.
• Support for Controller Area Network Flexible Data-Rate (CAN-FD) protocols for robust communication.
• High-performance processing capability driven by the ARM Cortex-M7 core running up to 300 MHz.

Applications

• Industrial motor control systems requiring precise analog feedback
• Automotive infotainment and body control modules utilizing CAN-FD
• Medical equipment needing high-resolution data conversion

Procurement Notes

Verify the specific suffix 'CNT' against official Microchip documentation to confirm tape-and-reel packaging status, as standard datasheets often list 'CN'. Ensure compatibility with moisture sensitivity levels and reflow soldering profiles specified in the latest product change notices. Confirm RoHS compliance details directly with the manufacturer.

Selection Notes

Select this component when a balance of high-speed processing and extensive analog connectivity is required. The inclusion of an AFE makes it suitable for applications demanding direct sensor interfacing without external multiplexers. Compare pin counts and memory sizes against other SAM S70 variants like the ATSAMS70N series if package constraints differ.

Part Context

This part belongs to the SAM S70 series, designed for complex embedded applications. It shares architectural similarities with the SAM E70 and SAM V70 families but distinguishes itself through specific peripheral configurations such as the integrated AFE and CAN-FD support found in the Q-series variants.

Replacement Considerations

Direct pin-compatible replacements within the same package include ATSAMS70Q19A-CN or ATSAMS70Q19B-CN, subject to verification of the specific 'CNT' reel configuration. Cross-family migration to SAM E70 requires interface mapping adjustments.
