Device Structure

The device integrates dual ARM Cortex-M4/M4F cores for concurrent operations, flash and RAM for program and data storage, a wide range of digital and analog peripherals, internal ADC, and power management including brown-out and power-on reset features—all within a compact 100-pin LQFP package suitable for surface mounting.

Performance Characteristics

High processing power with 120MHz dual-core capability supports complex, real-time tasks. Large program and RAM memory allow for advanced algorithms and multitasking. Multiple peripherals enable efficient communication and control. 10-bit ADC channels provide accurate analog signal conversion. Operates reliably over a wide temperature and voltage range.

Application Environments

Ideal for smart meters, industrial control, building automation, security systems, and energy management equipment needing high reliability and real-time control. Can also be used in instrumentation and advanced consumer electronics.

Selection Guidelines

Use this microcontroller when your application needs dual-core processing, robust peripheral integration, high-speed operation, and moderate to large on-chip memory. Check the number of I/O pins and peripheral options fit your hardware requirements. LQFP100 packaging requires appropriate PCB design for surface mount technology.

Usage Considerations

Confirm the supply voltage range matches your system. Observe MSL 3 handling to prevent moisture-induced failures after unsealing. Internal oscillator simplifies design but check timing accuracy for your application. No onboard EEPROM; provide external memory if non-volatile data is needed. Read temperature range to ensure suitability for your environment.

Potential Equivalent/Replacement Models

There are other Microchip SAM4CM series models with different memory sizes or core configurations, such as ATSAM4CMP32C-ANR and ATSAM4CMP16C-AUR for higher/lower flash sizes. ATSAM4CP series may be considered for similar use, depending on required features. No directly equivalent models are guaranteed; for the closest alternative, or cross to other manufacturers, please contact Ariat-Tech sales team for current recommendations and in-stock options.
