ATSAM4C32CA-AUR

Overview

The ATSAM4C32CA-AUR is a 32-bit microcontroller from the SAM4C series, featuring dual Arm Cortex-M4 processors operating at up to 120 MHz. It integrates 2 MB of embedded flash memory and 304 KB of SRAM. The device includes an on-chip cache for each core and supports a 16-bit external bus interface for memory expansion. It operates within a voltage range of 1.32 V to 3.6 V and is housed in a 100-pin LQFP package.

Feature Summary

• Dual-core architecture supporting simultaneous application and security processing
• Integrated cryptographic engine for secure data handling
• On-chip cache per processor core for enhanced performance
• External bus interface for program and data memory expansion

Applications

• Smart energy metering systems
• Industrial control applications requiring high security
• Communication gateways with encryption needs
• Medical devices with secure data transmission requirements

Procurement Notes

Verify the specific suffix 'AUR' indicates tape and reel packaging when ordering. Confirm the industrial temperature grade and RoHS compliance status with the manufacturer's current documentation. Ensure the 100-pin LQFP footprint matches your PCB design constraints before finalizing procurement.

Selection Notes

Select this component when dual-core processing power and integrated hardware security are required. Compare against single-core variants if only one processor is needed. Verify that the 2 MB flash and 304 KB RAM meet your application's memory requirements. Consider the 120 MHz maximum clock speed for real-time processing capabilities.

Part Context

This part belongs to the SAM4C family of microcontrollers designed for high-performance applications. It builds upon the Cortex-M4 architecture with added security features. The series targets markets needing robust processing alongside data protection. It serves as a system-level solution for complex embedded tasks.

Replacement Considerations

ATSAM4C32EA-AU offers identical specifications in a 144-pin LQFP package. Check pin compatibility if switching packages. No direct pin-to-pin substitutes exist within the same package type with different memory sizes.
