ATSAM3N00BA-AU

Overview

The ATSAM3N00BA-AU is a 32-bit microcontroller from the 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 peripherals such as I2C, SPI, UART/USART, and IrDA. It offers 47 general-purpose I/O pins and operates within a temperature range of -40°C to +85°C.

Feature Summary

ARM Cortex-M3 processor with Thumb-2 instruction set for efficient code execution
Integrated flash memory with hardware memory accelerator for single-cycle access
Multiple communication interfaces including USART, UART, SPI, and TWI/I2C
Built-in analog-to-digital converter and digital-to-analog converter

Applications

Industrial control systems requiring low-cost 32-bit processing
Consumer electronics and home automation devices
Portable battery-powered applications due to wide voltage support
General-purpose embedded control tasks

Procurement Notes

Verify the manufacturer designation, as Atmel products are now under Microchip Technology. Confirm the specific suffix 'AU' indicates the standard industrial temperature range and lead-free RoHS compliance. Ensure the 64-LQFP package dimensions match your PCB footprint requirements. Check for any obsolescence notices or lifecycle status changes before finalizing procurement plans.

Selection Notes

Select this component when a cost-effective 32-bit solution is needed with moderate memory capacity. It serves as a migration path from 8-bit or 16-bit architectures. Consider the 48 MHz speed limit and 16 KB flash size against application complexity. Verify that the available I/O count and peripheral sets meet system connectivity needs without requiring external chips.

Part Context

This part belongs to the SAM3N family, designed for entry-level applications. It shares architectural similarities with other SAM3N variants but differs in memory size. The series targets users migrating from older 8/16-bit MCUs. It provides a balance of performance and power efficiency for resource-constrained designs.
