Overview
The ATSAM4CMS16CA-AU is a 32-bit microcontroller from the Microchip SAM4CM series, featuring an ARM Cortex-M4/M4F dual-core processor. It integrates 1 MB of Flash memory and 256 kB of SRAM within a 100-pin LQFP package. The device operates at a maximum clock frequency of 120 MHz and supports a supply voltage range of 1.62 V to 3.6 V. Key peripherals include multiple communication interfaces such as SPI, I2C, USART, and USB, alongside a 6-channel 10-bit ADC.
Feature Summary
- Dual-core architecture combining ARM Cortex-M4 and M4F processors for enhanced computational throughput
- Integrated high-speed serial communication capabilities including USB and standard peripheral interfaces
- On-chip non-volatile memory with substantial data RAM for complex application execution
Applications
- Industrial control systems requiring deterministic processing
- Medical devices needing high-performance signal processing
- Consumer electronics utilizing USB connectivity
Procurement Notes
Verify component authenticity through authorized Microchip distributors or certified partners. Confirm lot traceability and RoHS compliance status prior to integration. Ensure storage conditions adhere to moisture sensitivity level requirements to prevent package damage during assembly processes.
Selection Notes
Select this model when dual-core processing power is required within a 100-pin footprint. Compare against single-core alternatives like the ATSAM4S series if cost reduction is prioritized over performance. Evaluate pin compatibility with existing designs when migrating from similar SAM4CM variants.
Part Context
This component belongs to the SAM4CM family, designed for applications demanding high performance and low power consumption. It shares architectural similarities with other SAM4 series devices but offers distinct dual-core advantages. The LQFP-100 package provides balanced thermal performance and I/O density for embedded solutions.
Replacement Considerations
Direct substitutes include other ATSAM4CMS16CA variants with different suffixes indicating temperature or packaging changes. Cross-series migration to ATSAM4E or ATSAM4S requires software adaptation due to peripheral differences.
