ATSAM4CMP16CC-AU

Overview

The ATSAM4CMP16CC-AU is an ARM microcontroller from the SAM4CM series, featuring a dual-core architecture with ARM Cortex-M4 and Cortex-M4F processors. It operates at a maximum clock frequency of 120 MHz and includes 1 MB of embedded Flash memory alongside 152 kB of SRAM. The device provides 52 general-purpose I/O pins and supports a supply voltage range of 1.08 V to 1.32 V. It integrates six 10-bit ADC channels and interfaces including SPI, UART, USART, and I2C. Packaged in a 100-LQFP format, it functions within a temperature range of -40°C to +85°C.

Feature Summary

• Dual-core processing capability combining ARM Cortex-M4 and Cortex-M4F for enhanced computational performance.
• Integrated cryptographic engine supporting secure data handling and authentication protocols.
• Multi-Role Low-Cost (MRLC) interface configuration enabling flexible peripheral connectivity.
• Industrial temperature rating suitable for operation in demanding environmental conditions.

Applications

• Secure industrial control systems requiring hardware-level encryption
• Smart metering applications with robust data integrity needs
• Embedded security modules for access control and authentication

Procurement Notes

Verify the specific suffix 'AU' confirms the LQFP-100 package and industrial temperature grade. Ensure compatibility with the 1.08 V to 1.32 V core voltage requirements rather than standard 3.3 V logic levels without appropriate translation. Confirm RoHS compliance status through official Microchip documentation prior to integration into regulated assemblies.

Selection Notes

Select this component when dual-core processing combined with hardware crypto acceleration is required within a compact LQFP-100 footprint. It is appropriate for designs needing 1 MB of program storage and strict low-voltage operation constraints. Compare against non-crypto variants if security features are unnecessary to optimize cost.

Part Context

This part belongs to the ATSAM4CMP16C family, which extends the SAM4CM series with dedicated cryptographic capabilities. It targets applications where data security and processing efficiency must coexist. The MRLC designation indicates optimized peripheral sets for cost-sensitive yet secure embedded deployments.

Replacement Considerations

ATSAM4CMP16CC-AUR offers identical functionality in tape-and-reel packaging instead of trays. Non-crypto equivalents like ATSAM4CMS16CC-AU lack the integrated cryptographic engine but share the same core architecture and pinout.
