ATSAM4CMP32CA-AUR

Overview

The ATSAM4CMP32CA-AUR is a 32-bit microcontroller from the SAM4C series, manufactured by Microchip Technology. It features a dual-core ARM Cortex-M4 architecture with a maximum clock frequency of 120 MHz. The device integrates 2 MB of embedded flash memory and 304 KB of SRAM. It operates within a supply voltage range of 1.62 V to 3.6 V and supports an industrial temperature range of -40°C to +85°C. The component is housed in a 100-pin LQFP package.

Feature Summary

• Dual-core ARM Cortex-M4 processor architecture for integrated application and security processing
• High-performance execution at up to 120 MHz with on-chip cache support
• Integrated cryptographic engine for secure data handling
• Extensive peripheral set including USB, Ethernet MAC, and multiple communication interfaces

Applications

• Smart energy metering systems requiring high security
• Industrial control applications with complex communication needs
• Medical devices demanding robust data integrity
• Automotive infotainment and gateway controllers

Procurement Notes

Verify the specific suffix 'AUR' indicates tape and reel packaging when ordering. Confirm the 'CA' designation matches the required pinout and thermal specifications for your PCB design. Ensure the supplier provides official Microchip documentation to validate authenticity and revision level before integration into production.

Selection Notes

Select this model when dual-core processing isolation between application and security layers is required. The 2 MB flash capacity suits complex firmware implementations. Compare against single-core variants if power consumption is critical, as the dual-core setup offers higher computational throughput for demanding real-time tasks.

Part Context

This component belongs to the SAM4C family, designed for high-end applications needing strong security features. It shares architectural similarities with other SAM4C parts but differs in memory size and package options. The dual-core design distinguishes it from standard single-core MCUs in the broader ARM ecosystem.

Replacement Considerations

Direct substitutes include other SAM4C series parts like ATSAM4C32CA-AU or ATSAM4C32EA-AU, depending on package requirements. Verify compatibility regarding pin assignments and software libraries when migrating from single-core SAM4S or SAM4L series components.
