ATSAM3N00BA-AUR

Overview

The ATSAM3N00BA-AUR is a 32-bit microcontroller from the Microchip SAM3N series, featuring an ARM Cortex-M3 core operating at up to 48 MHz. It integrates 16 KB of flash memory and 4 KB of SRAM within a 64-LQFP package. The device supports a supply voltage range of 1.62 V to 3.6 V and includes eight 10-bit ADC channels. Connectivity options comprise I2C, SPI, and UART interfaces, while peripherals include DMA, PWM, and watchdog timers.

Feature Summary

• Integrates an ARM Cortex-M3 processor with Thumb-2 instruction set support for efficient code execution.
• Includes embedded flash memory with 128-bit wide access and a dedicated memory accelerator.
• Features an internal voltage regulator enabling single-supply operation across specified ranges.
• Provides hardware security mechanisms including power-on-reset and brown-out detection.

Applications

• Industrial control systems requiring robust peripheral integration
• Consumer electronics utilizing low-power ARM-based processing
• Embedded applications needing secure boot and data integrity features

Procurement Notes

Verify the specific suffix 'AUR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the industrial temperature rating aligns with environmental constraints. Ensure compatibility with existing design tools by checking for updated EDA models and software framework support from the manufacturer.

Selection Notes

Select this component when a balance of moderate program storage and compact pin count is necessary. The 64-pin LQFP package offers sufficient I/O for many interface-heavy designs without excessive board space consumption. Consider the internal oscillator accuracy if precise timing is critical for communication protocols.

Part Context

This part belongs to the SAM3N family, designed as a cost-effective solution for applications not requiring high-performance networking or complex multimedia processing. It serves as a bridge between legacy 8/16-bit architectures and higher-end 32-bit MCUs, offering pin-to-pin compatibility with older SAM7S devices in certain form factors.

Replacement Considerations

Consult official substitution lists for variants with different memory sizes or package types within the SAM3N series. Verify cross-compatibility with other ARM Cortex-M3 based controllers only after confirming register-level and electrical specification alignment.
