Overview
The ATSAM3N0BA-AU is a 32-bit microcontroller from the SAM3N series, featuring an ARM Cortex-M3 core operating at a maximum frequency of 48 MHz. It integrates 32 kB of Flash program memory and 8 kB of data RAM within a 64-pin LQFP package. The device supports a supply voltage range of 1.8 V to 3.6 V and includes 47 general-purpose I/O lines. Peripheral interfaces include multiple SPI, UART/USART, and TWI channels, alongside a 10-bit ADC.
Feature Summary
- Integrates an ARM Cortex-M3 processor with Thumb-2 instruction set for efficient code execution
- Provides embedded Flash memory with hardware memory accelerator for high-speed access
- Supports low-power operation through various sleep modes and power-down states
- Includes built-in analog-to-digital conversion and pulse-width modulation capabilities
Applications
- General-purpose embedded control systems
- Low-cost industrial automation controllers
- Consumer electronics devices requiring 32-bit processing
- Battery-powered applications due to low voltage operation
Procurement Notes
Verify the specific suffix 'AU' corresponds to the lead-free, RoHS-compliant variant in the official Microchip datasheet. Confirm the package type is LQFP-64 and check for any recent Product Change Notifications regarding assembly sites or material composition updates before finalizing procurement specifications.
Selection Notes
Select this component when a balance of moderate Flash capacity and low pin count is required. It serves as a migration path from 8-bit or 16-bit architectures. Ensure the design utilizes the 1.8V to 3.6V supply range and that the 48 MHz clock speed meets the application's timing requirements without exceeding thermal limits in the LQFP package.
Part Context
This part belongs to the Atmel (now Microchip) SAM3N family, designed as entry-level 32-bit MCUs. The series emphasizes cost-effectiveness and compatibility with other SAM3 variants. The ATSAM3N0BA-AU represents a specific configuration within this lineup, offering 32 kB Flash and 8 kB RAM for compact embedded solutions.
Replacement Considerations
Consult the official SAM3N datasheet for direct pin-compatible substitutes such as ATSAM3N0CA-AU or ATSAM3N1BA-AU, depending on required memory sizes. Verify that any replacement maintains the same LQFP-64 footprint and electrical characteristics.
