ATSAM4C32CA-AUT

Overview

The ATSAM4C32CA-AUT is a 32-bit microcontroller from the SAM4C series, manufactured by Microchip Technology. It features an ARM Cortex-M4 core operating at a maximum clock frequency of 120 MHz. The device integrates 2 MB of embedded flash memory and 304 KB of SRAM. It utilizes a 100-pin LQFP package with an industrial temperature range rating. Key specifications include a 32-bit data bus width, 106 I/O lines, and a supply voltage range of 1.32 V to 3.6 V.

Feature Summary

• Dual-core architecture supporting simultaneous application and security processing
• Integrated cryptographic engine for secure data handling
• External Bus Interface (EBI) for memory expansion capabilities

Applications

• Smart energy metering systems
• Industrial control applications requiring high performance
• Secure communication devices

Procurement Notes

Verify the specific suffix 'AUT' against official Microchip documentation to confirm tape-and-reel packaging and industrial temperature grade alignment. Ensure compatibility with existing PCB footprints for the LQFP-100 package. Cross-reference pinouts and electrical characteristics with the latest datasheet revision to avoid integration errors during procurement.

Selection Notes

Select this component when dual-core processing and hardware security are required within a single MCU. Compare memory sizes and I/O counts against alternatives like the ATSAM4C32EA-AU if different package constraints exist. Evaluate power consumption profiles against low-power SAM4L series options if battery operation is critical.

Part Context

This part belongs to the SAM4C family, designed for smart energy and industrial markets. It distinguishes itself through the integration of two Cortex-M4 cores and dedicated security features. The CA suffix typically denotes specific package and temperature variations within the broader SAM4C product line.

Replacement Considerations
