ATSAM4C16CB-AU

Overview

The ATSAM4C16CB-AU is a 32-bit microcontroller from the SAM4C series, featuring an ARM Cortex-M4/M4F dual-core processor running at 120MHz. It integrates 1MB of Flash memory and 128KB of SRAM within a 100-LQFP package. The device supports a supply voltage range of 1.62V to 3.6V and operates between -40°C and 85°C. Key peripherals include EBI/EMI, I2C, IrDA, SPI, UART/USART, and various safety features like DMA and watchdog timers.

Feature Summary

• Dual-core ARM Cortex-M4/M4F architecture for integrated application and security processing
• High-performance 120MHz operation with embedded Flash and SRAM
• Comprehensive connectivity including EBI/EMI, I2C, SPI, and USART interfaces
• Integrated safety peripherals such as DMA, POR, and WDT

Applications

• Smart metering systems requiring secure data handling
• Industrial control applications needing high-speed processing
• Devices utilizing external memory expansion via EBI/EMI

Procurement Notes

Verify the specific suffix 'AU' corresponds to the 100-LQFP industrial temperature grade package. Confirm RoHS compliance status through official Microchip documentation prior to procurement. Ensure compatibility with existing PCB footprints for the 100-LQFP form factor.

Selection Notes

Select this component when dual-core processing capabilities are required for separating real-time tasks from security functions. The 1MB Flash and 128KB RAM provide sufficient resources for complex firmware. Consider the 100-LQFP package constraints and 1.62V-3.6V operating voltage range against system power requirements.

Part Context

Part of the SAM4C family designed for high-performance embedded applications. It builds upon the SAM4S architecture with added dual-core capabilities and enhanced security features. The series targets markets demanding robust processing power and secure execution environments in a compact footprint.

Replacement Considerations

ATSAM4C16CA-AU: Same core and memory but different package (BGA). ATSAM4S16CB-AU: Single-core alternative with similar memory and package. Verify pinout and peripheral availability differences before substitution.
