ATSAM4C16CA-AUR

Overview

The ATSAM4C16CA-AUR is a 32-bit microcontroller based on the ARM Cortex-M4 core, operating at a maximum frequency of 120 MHz. It features 1 MB of embedded Flash memory and 152 kB of SRAM. The device includes an integrated cryptographic engine for secure applications. It utilizes a 100-pin LQFP package and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Dual-core architecture integrating application processing with dedicated security functions
• Integrated hardware cryptographic engine supporting standard algorithms
• Supports external memory expansion via 16-bit External Bus Interface

Applications

• Smart metering systems requiring secure data handling
• Industrial control units with communication layer integration
• Secure authentication devices utilizing hardware crypto engines

Procurement Notes

Verify the specific suffix 'AUR' indicates tape-and-reel packaging when sourcing. Confirm the 'CA' designation aligns with the required pinout and memory configuration for your PCB layout. Ensure compatibility with the 1.62 V to 3.6 V supply voltage range in your power design.

Selection Notes

Select this component if your design requires a dual-core Cortex-M4 solution with integrated security features. Compare against the ATSAM4C16CB series if TQFP packaging is preferred over LQFP. Verify that the 152 kB SRAM meets your runtime data requirements before finalizing the part number.

Part Context

This part belongs to the SAM4C family of high-performance microcontrollers designed for smart energy and industrial applications. It distinguishes itself by combining two Cortex-M4 cores with a dedicated cryptographic engine, allowing separation of application logic and security protocols within a single chip.

Replacement Considerations

The ATSAM4C16CB-AU is a pin-compatible alternative offering similar specifications but in a TQFP-100 package instead of LQFP-100. Verify package dimensions and thermal characteristics before substitution.
