ATSAM4CMS16CC-AUT

Overview

The ATSAM4CMS16CC-AUT is an ARM Cortex-M4 microcontroller from the SAM4CM series, manufactured by Microchip Technology. It features a 1 MB Flash program memory and 152 kB SRAM data RAM within a TQFP-100 package. The device operates at a maximum clock frequency of 20 MHz with a supply voltage range of 1.62 V to 3.6 V. It includes 52 I/O lines, six 10-bit ADC channels, and interfaces such as I2C, SPI, UART, and PWM. The component supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Integrates ARM Cortex-M4 core with cryptographic capabilities for secure processing
• Includes embedded flash memory and static RAM for code execution and data storage
• Supports multiple communication protocols including I2C, SPI, and UART

Applications

• Industrial control systems requiring secure data handling
• Smart metering applications with encryption needs
• Consumer electronics utilizing low-power ARM architectures

Procurement Notes

Verify the specific suffix 'AUT' against official Microchip documentation to confirm automotive qualification status and operating temperature ratings. Ensure compatibility with required packaging formats and check for any recent product change notices affecting pinout or electrical characteristics before finalizing procurement.

Selection Notes

Select this component when a balance of moderate processing speed and integrated security features is required. The 20 MHz limit distinguishes it from higher-speed SAM4 variants. Verify that the 152 kB RAM suffices for application stack requirements and that the TQFP-100 package fits the PCB layout constraints.

Part Context

This part belongs to the SAM4CM family, which targets high-performance, low-power applications. Unlike the dual-core SAM4CM variants, this single-core model focuses on cost-effective security integration. It shares architectural similarities with the SAM4S series but offers distinct memory configurations and peripheral sets tailored for specific embedded control tasks.

Replacement Considerations

Consult Microchip's official cross-reference tools for verified substitutes. Potential alternatives within the SAM4CM or SAM4S families may offer different memory sizes or package options while maintaining pin compatibility.
