ATSAMS70N19B-CFNT

Overview

The ATSAMS70N19B-CFNT is a 32-bit microcontroller from the Microchip SAM S70 series, featuring an ARM Cortex-M7 core operating at up to 300 MHz. It integrates 512 KB of Flash memory and 256 KB of SRAM within a 100-pin VFBGA package. The device includes a 12-bit Analog Front End (AFE), 12-bit DACs, and supports CAN-FD communication. It operates on a supply voltage range of 1.7 V to 3.6 V and functions within a temperature range of -40°C to +105°C.

Feature Summary

• Integrates an ARM Cortex-M7 processor core for high-performance computing capabilities.
• Includes a dedicated 12-bit Analog Front End (AFE) for signal conditioning.
• Supports Controller Area Network with Flexible Data-Rate (CAN-FD) protocols.
• Features integrated 12-bit Digital-to-Analog Converters (DACs).

Applications

• Industrial automation control systems
• Automotive body electronics and instrumentation
• Medical equipment requiring precise analog signal processing
• Smart metering and utility infrastructure

Procurement Notes

Verify the specific suffix CFNT indicates tape-and-reel packaging when sourcing components. Confirm the B revision status against current Microchip production notices. Ensure compatibility with existing PCB footprints for the 100-VFBGA package. Validate that the CAN-FD and AFE features meet the specific design requirements before finalizing procurement orders.

Selection Notes

Select this component when a balance of moderate memory capacity and advanced analog features is required. The 512 KB Flash and 256 KB SRAM suit applications not demanding extensive data storage. The inclusion of the AFE and CAN-FD makes it suitable for noisy industrial environments. Compare against the ATSAMS70N19A variant if older silicon revisions are acceptable or cost-sensitive.

Part Context

This part belongs to the SAM S70 family, designed for high-performance embedded applications. It shares architectural similarities with the SAM E70 but focuses on automotive and industrial robustness. The N19 designation typically denotes the 512 KB Flash and 256 KB SRAM configuration within the 100-pin form factor.
