ATSAM4C32CA-AUTR

Overview

The ATSAM4C32CA-AUTR is a 32-bit microcontroller based on the dual-core ARM Cortex-M4 architecture. It features 2 MB of embedded flash memory and 304 KB of SRAM, operating at a maximum clock frequency of 120 MHz. The device includes an internal cache for each core and supports external memory expansion via a 16-bit bus interface. 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 ARM Cortex-M4 architecture enabling integration of application and security functions
• Integrated cryptographic engine supporting secure data processing
• On-chip cache per core for improved instruction execution efficiency
• External memory interface for expanding program and data storage

Applications

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

Procurement Notes

Verify the specific suffix 'AUTR' indicates tape and reel packaging when sourcing components. Confirm that the part number matches the exact pin count and package type required for your PCB layout. Ensure compatibility with the intended operating temperature range specified in the official datasheet before finalizing procurement orders.

Selection Notes

Select this component when a dual-core solution is necessary to separate real-time tasks from complex processing or security operations. The 2 MB flash capacity suits applications requiring significant code storage without external memory. Consider the 100-pin LQFP package constraints regarding available board space and thermal management requirements for the target environment.

Part Context

This model belongs to the SAM4C series of microcontrollers designed for smart energy applications. It distinguishes itself by offering two independent Cortex-M4 cores, allowing for parallel processing of different system layers. The series emphasizes security through integrated hardware encryption capabilities alongside standard peripheral interfaces.

Replacement Considerations

Check for ATSAM4C32CA-AU as a potential tray-packaged alternative if volume handling differs. Verify cross-compatibility with other SAM4C variants only if pinout and memory specifications align exactly.
