ATSAM4C16CA-AU

Overview

The ATSAM4C16CA-AU is a 32-bit microcontroller based on the ARM Cortex-M4/M4F core, operating at speeds up to 120MHz. It features 1MB of embedded 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 includes an internal oscillator. Peripheral interfaces include EBI/EMI, I2C, IrDA, SPI, and UART/USART. It provides 74 general-purpose I/O pins and integrates peripherals such as DMA, LCD controller, PWM, and watchdog timer.

Feature Summary

Dual-core architecture supporting simultaneous execution of application and communication layers
Integrated LCD controller for display management applications
External Bus Interface (EBI) enabling expansion of program and data memories

Applications

Industrial control systems requiring dual-core processing
Smart metering platforms with security integration needs
Embedded devices utilizing external memory expansion via EBI

Procurement Notes

Verify the specific suffix against official Microchip documentation to confirm pinout and feature variations. Ensure compatibility with existing PCB footprints for the 100-LQFP package. Confirm that the required peripheral set matches the specific variant's availability in public datasheets.

Selection Notes

Select this component when dual-core processing capabilities are required alongside external memory expansion. The inclusion of an LCD controller makes it suitable for graphical interface applications. Verify that the 120MHz performance meets system timing requirements and that the 100-pin package fits the design constraints.

Part Context

This part belongs to the SAM4C series, designed for high-performance applications. It distinguishes itself from single-core variants by offering two Cortex-M4 cores. The series targets complex embedded systems needing robust processing power and extensive connectivity options within a compact form factor.
