ATSAM4C16CB-AU

Overview

The ATSAM4C16CB-AU is a 32-bit microcontroller from the SAM4C series, featuring a dual-core ARM Cortex-M4/M4F architecture. It operates at a maximum speed of 120MHz and includes 1MB of embedded Flash memory and 128KB of SRAM. The device provides 74 I/O pins and supports multiple communication interfaces including EBI/EMI, I2C, IrDA, SPI, and UART/USART. It functions within a supply voltage range of 1.62V to 3.6V and is housed in a 100-LQFP package.

Feature Summary

• Dual-core ARM Cortex-M4/M4F processor for high-performance computing
• Integrated Memory Protection Unit (MPU) and DSP instruction set
• Supports external memory interfaces via Static Memory Controller
• Includes hardware security features such as AES and SHA-256

Applications

• Industrial control systems requiring deterministic processing
• Medical devices with cryptographic security requirements
• Automotive infotainment and gateway applications
• Smart home automation hubs

Procurement Notes

Verify the specific suffix 'AU' corresponds to the 100-LQFP package and industrial temperature range (-40°C to +85°C). Confirm that the component is sourced from authorized Microchip distributors to ensure authenticity. Check for any lead-free or RoHS compliance documentation required for your manufacturing process. Ensure the ordering quantity matches the standard supplier packaging specifications.

Selection Notes

Select this model when dual-core processing power is necessary for complex real-time tasks alongside security operations. The 1MB Flash capacity suits applications with large firmware footprints. Consider the 100-LQFP package if board space allows for surface-mount assembly. Verify that the 128KB RAM meets the stack and heap requirements of the intended operating system or bare-metal application.

Part Context

This component belongs to the Atmel SAM4C family, designed for high-performance applications. It succeeds earlier SAM3 series devices by offering enhanced security and dual-core capabilities. The SAM4C series targets markets demanding robust data processing and secure boot functionalities. It is manufactured by Microchip Technology following the acquisition of Atmel.

Replacement Considerations

Check for pin-compatible alternatives within the SAM4C series, such as variants with different memory sizes. Verify that substitute parts maintain the same dual-core architecture and security feature sets. Ensure the replacement package matches the 100-LQFP form factor for direct board integration.
