ATSAM4CMS8CC-AUT

Overview

The ATSAM4CMS8CC-AUT is a 32-bit microcontroller from the SAM4CM series, manufactured by Microchip Technology. It features a dual-core ARM Cortex-M4/M4F processor architecture operating at a maximum frequency of 120 MHz. The device integrates 1024 KB (1 MB) of embedded Flash memory and 152 KB of SRAM. It is housed in a 100-pin TQFP package with an industrial temperature range of -40°C to +85°C. Power supply requirements are between 1.62 V and 3.6 V. Connectivity options include I2C, SPI, UART/USART, and IrDA interfaces.

Feature Summary

• Dual-core ARM Cortex-M4/M4F architecture for high-performance processing
• Integrated cryptographic security features within the SAM4CM family
• Supports Multiple Random Logic Code (MRLC) configurations
• Includes built-in hardware acceleration for digital signal processing

Applications

• Industrial control systems requiring secure data processing
• Smart metering applications with encryption needs
• Automotive infotainment subsystems
• Medical devices with strict security protocols

Procurement Notes

Verify the specific suffix 'AUT' corresponds to the TQFP-100 package and industrial temperature grade (-40°C to +85°C). Confirm that the MRLC configuration matches your design requirements. Check for RoHS3 compliance status as per the latest datasheet revision. Ensure ESD handling procedures are followed during assembly due to the surface-mount technology.

Selection Notes

Select this component when dual-core processing power combined with hardware-based security is required. Compare against single-core variants if cryptographic overhead is unnecessary. Verify pin compatibility with existing PCB layouts designed for the 100-LQFP or TQFP form factors. Consider the 120 MHz clock speed relative to power consumption constraints in battery-operated scenarios.

Part Context

This part belongs to the SAM4CM series, which extends the capabilities of the SAM4S line with enhanced security and dual-core performance. It is designed for applications demanding robust protection against physical attacks and software exploits. The series supports various memory configurations to balance cost and performance requirements across different market segments.

Replacement Considerations

ATSAM4CMS8CC-AU: Identical core specifications but packaged in LQFP-100 instead of TQFP-100.
