ATSAM3N00AA-MU

Overview

The ATSAM3N00AA-MU is a 32-bit microcontroller based on the ARM Cortex-M3 core, operating at a maximum frequency of 48 MHz. It features 16 KB of flash memory and 4 KB of SRAM. The device supports a supply voltage range of 1.62 V to 3.6 V and includes an internal oscillator. Connectivity options include I2C, SPI, and UART/USART interfaces. It provides 34 general-purpose I/O pins and integrates peripherals such as DMA, PWM, and watchdog timers. The unit is housed in a 48-QFN package with dimensions of 7x7 mm.

Feature Summary

• Integrates an ARM Cortex-M3 processor core for efficient code execution.
• Includes built-in analog-to-digital conversion capabilities.
• Supports direct memory access for peripheral data transfer.
• Features programmable pulse width modulation outputs.

Applications

• Industrial automation control systems
• Smart grid monitoring devices
• Medical equipment controllers
• Building and home automation hubs

Procurement Notes

Verify the specific suffix 'MU' corresponds to the QFN-48 package and industrial temperature range during sourcing. Confirm RoHS compliance status through official Microchip documentation. Ensure the component matches the SAM3N series specifications exactly. Check for any recent production change notices affecting assembly sites or marking changes before finalizing procurement orders.

Selection Notes

Select this model when a compact 48-pin footprint is required alongside standard ARM Cortex-M3 performance. It serves as a suitable alternative to the AU variant for designs necessitating a quad flat no-lead package. Consider the 16 KB flash capacity for applications with moderate code storage requirements. Verify that the 34 available I/O pins meet the interface demands of the target system design.

Part Context

This component belongs to the Microchip SAM3N family of low-power, cost-effective microcontrollers. The family utilizes the ARM Cortex-M3 architecture to deliver high performance with reduced power consumption. These devices are designed for applications requiring reliable embedded control in industrial and consumer environments. The ATSAM3N00AA-MU represents a specific pinout and packaging option within this broader product line.

Replacement Considerations

ATSAM3N00AA-AU offers identical electrical specifications but utilizes a 48-LQFP package instead of QFN. ATSAM3N00AA-MUR provides the same QFN-48 form factor but comes in tape and reel packaging for automated assembly. Both alternatives maintain the same core functionality and memory configuration.
