Overview
The ATSAM4CMS16CC-AUTR is an ARM Cortex-M4 microcontroller from the Microchip SAM4CM series, featuring a dual-core architecture with two independent M4/M4F processors. It integrates 1 MB of embedded flash memory and 152 kB of SRAM within a TQFP-100 package. The device supports a maximum clock frequency of 20 MHz and operates on a supply voltage ranging from 1.62 V to 3.6 V. Key peripherals include six 10-bit ADC channels, multiple communication interfaces such as I2C, SPI, UART, and PWM, along with 52 general-purpose I/O pins. It is designed for industrial temperature ranges from -40°C to +85°C.
Feature Summary
- Dual-core ARM Cortex-M4/M4F architecture enabling simultaneous execution of application and security tasks.
- Integrated hardware cryptographic engine supporting secure data processing and authentication.
- Comprehensive peripheral set including DMA controllers, LCD interface, and multiple serial communication modules.
Applications
- Industrial control systems requiring high reliability and secure communication.
- Smart metering applications utilizing integrated cryptographic features.
- Medical devices needing robust data integrity and low-power operation.
Procurement Notes
Verify the specific suffix 'AUTR' against official Microchip documentation to confirm tape-and-reel packaging status, as standard datasheets may list tray packaging for similar variants. Ensure compatibility with required operating temperature ranges and voltage levels before integration. Cross-reference the exact part number with current production notices to avoid obsolete stock issues.
Selection Notes
Select this component when a dual-core solution is necessary to separate real-time safety functions from application logic. The 1 MB flash capacity suits complex firmware requirements without external memory expansion. Consider the 20 MHz limit compared to higher-speed SAM4C models if power consumption is a critical constraint.
Part Context
This MCU belongs to the SAM4CM family, which targets cost-sensitive applications requiring enhanced security features. Unlike the high-performance SAM4C series, the SAM4CM offers optimized performance for mid-range embedded systems. The dual-core design allows for partitioned software development, improving system stability and security compliance in regulated industries.
Replacement Considerations
Direct substitutes within the same package and pinout include other SAM4CM variants with different memory sizes, such as ATSAM4CMS4CC or ATSAM4CMS8CC. Verify that the replacement part maintains the required flash and RAM capacities for your specific application firmware.
