ATSAM4CMS4CC-AU

Overview

The ATSAM4CMS4CC-AU is a 32-bit microcontroller from the SAM4CM series, featuring a dual-core ARM Cortex-M4/M4F architecture. It integrates 256 KB of flash memory and 128 KB of SRAM within a 100-LQFP package. The device operates at a maximum clock frequency of 120 MHz with a supply voltage range of 1.62 V to 3.6 V. Key peripherals include six 10-bit ADC channels, an LCD controller, DMA, and standard communication interfaces such as I2C, SPI, UART, and USART.

Feature Summary

• Dual-core processing capability combining ARM Cortex-M4 and Cortex-M4F cores for enhanced computational performance.
• Integrated LCD controller supporting display management alongside general-purpose input/output functions.
• Direct Memory Access (DMA) support for efficient data transfer between peripherals and memory without CPU intervention.

Applications

• Industrial control systems requiring high-speed processing and display output
• Smart metering applications utilizing analog-to-digital conversion capabilities
• Embedded devices needing secure code execution with cryptographic hardware acceleration

Procurement Notes

Verify component authenticity through authorized Microchip distributors or certified partners. Confirm lot traceability and RoHS compliance status prior to procurement. 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 efficiency is required within a 100-pin form factor. Compare against single-core variants if core count is not critical. Verify peripheral availability, specifically the presence of the LCD controller and specific ADC channel counts, against system design requirements.

Part Context

This component belongs to the SAM4CM family, designed for applications demanding high performance and low power consumption. It serves as an upgrade path for legacy ARM7-based designs, offering significant improvements in instruction throughput and peripheral integration while maintaining software compatibility with existing ARM Cortex-M development tools.

Replacement Considerations

ATSAM4CMS4CB-AU: Similar specifications but lacks the second M4F core. ATSAM4CMS4CA-AU: Different pinout and peripheral configuration. Verify functional equivalence and pin compatibility before substitution.
