ATSAM4CMS8CC-AUR

Overview

The ATSAM4CMS8CC-AUR is a 32-bit microcontroller from the SAM4CM series, manufactured by Microchip Technology. It features a dual-core ARM Cortex-M4/M4F architecture operating at 120MHz. The device integrates 1024KB of flash memory and includes hardware security features such as crypto acceleration. It is housed in a 100-LQFP package with an industrial temperature range of -40°C to +85°C.

Feature Summary

• Dual-core ARM Cortex-M4/M4F processor for high-performance computing
• Integrated hardware cryptographic acceleration for secure data processing
• Supports One-Time Programmable (OTP) memory for unique device identification

Applications

• Industrial control systems requiring deterministic real-time performance
• Secure embedded applications utilizing hardware-based encryption
• Complex motor control and automation interfaces

Procurement Notes

Verify the specific suffix 'AUR' against official Microchip documentation to confirm tape-and-reel packaging and RoHS compliance status. Ensure the part number matches the exact pinout and memory configuration required for your design, as variations exist within the SAM4CM family. Cross-reference the datasheet revision date to confirm current silicon errata and functional specifications before finalizing procurement.

Selection Notes

Select this component when a dual-core solution is necessary for separating real-time tasks from complex application logic. The integrated crypto engine makes it suitable for devices requiring robust security without external components. Compare the 1024KB flash capacity against project requirements to ensure sufficient code storage. Verify that the 100-LQFP package fits the available PCB space and thermal constraints.

Part Context

This part belongs to the SAM4CM series, which targets high-performance applications. It differs from single-core variants like the ATSAM4S or low-power ATSAM4L series by offering higher throughput through its dual-core architecture. The 'MRLC' designation typically indicates specific manufacturing and reliability standards defined by Microchip for this product line.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Potential alternatives within the same family include the ATSAM4CMP16CC-AUR for increased memory or the ATSAM4CMS8CC-AU for tray packaging. Do not assume compatibility with other series without verifying pinouts and software libraries.
