Substitute Part Grouping Explanation

Substitution eligibility for the ATXMEGA384D3-MN is determined by strict equivalence across the following critical parameters:

• Base Product Number: ATXMEGA384 (identical across all variants)
• Core Architecture: AVR 8/16-bit processor
• Clock Speed: 32MHz
• Memory Configuration: 384KB flash, 4KB EEPROM, 32KB RAM
• I/O Count: 50 pins
• Connectivity Interfaces: I2C, IrDA, SPI, UART/USART
• Peripheral Set: Brown-out Detect/Reset, DMA, POR, PWM, WDT
• Data Converter: A/D 16x12b
• Package Type: 64-QFN (9x9) with exposed pad
• Supply Voltage Range: 1.6V ~ 3.6V
• RoHS Compliance: ROHS3 Compliant

Variations between the main part and substitutes are limited to packaging format (tube vs. tray) and maximum operating temperature specification.

Parameter Comparison

Engineering Selection Recommendations

Both the ATXMEGA384D3-MN and ATXMEGA384D3-MH are functionally equivalent microcontrollers with identical electrical specifications, memory configurations, and peripheral sets. Selection between these parts should be based on the following factors:

Operating Temperature Range: The ATXMEGA384D3-MN supports an extended operating temperature range of -40°C to 105°C, while the ATXMEGA384D3-MH is rated to -40°C to 85°C. Applications requiring operation above 85°C must use the ATXMEGA384D3-MN.

Packaging and Supply Chain: The ATXMEGA384D3-MN is supplied in tube packaging, while the ATXMEGA384D3-MH is supplied in tray packaging. Packaging selection depends on assembly process requirements and inventory management practices.

Compliance and Certifications: Both parts maintain ROHS3 compliance, identical moisture sensitivity levels (MSL 3), and active product status from Microchip Technology. Both are suitable for applications requiring regulatory compliance in electronics manufacturing.

Inventory Availability: Current stock levels are 1041 units for ATXMEGA384D3-MN and 1025 units for ATXMEGA384D3-MH, indicating consistent availability for both variants.

Frequently Asked Questions (FAQ)

Q: Can ATXMEGA384D3-MH be used as a direct replacement for ATXMEGA384D3-MN?

A: The ATXMEGA384D3-MH is functionally equivalent to the ATXMEGA384D3-MN for all electrical and operational characteristics. However, the maximum operating temperature of the ATXMEGA384D3-MH is limited to 85°C, compared to 105°C for the ATXMEGA384D3-MN. Direct substitution is appropriate only for applications where the operating temperature does not exceed 85°C.

Q: What is the difference between tube and tray packaging?

A: Tube packaging (ATXMEGA384D3-MN) and tray packaging (ATXMEGA384D3-MH) are different supply formats for the same component. Tube packaging is typically used for lower-volume orders and manual assembly, while tray packaging is optimized for automated pick-and-place assembly processes. The electrical and mechanical properties of the component are identical.

Q: Are both parts RoHS compliant?

A: Yes, both ATXMEGA384D3-MN and ATXMEGA384D3-MH are ROHS3 compliant and suitable for applications requiring RoHS certification.

Q: What is the moisture sensitivity level, and why does it matter?

A: Both parts have a Moisture Sensitivity Level (MSL) of 3 with a floor life of 168 hours. This means the components must be stored in controlled humidity conditions and have a limited shelf life once the packaging is opened. Proper handling and storage procedures must be followed to prevent moisture absorption, which can cause soldering defects.

Q: Can I use these microcontrollers in high-temperature applications?

A: The ATXMEGA384D3-MN supports operation up to 105°C and is suitable for high-temperature applications. The ATXMEGA384D3-MH is limited to 85°C maximum operating temperature and is not suitable for applications exceeding this temperature.

Q: Are the pin configurations identical between these two parts?

A: Yes, both parts use the same 64-QFN (9x9) package with 50 I/O pins and identical pinout configurations. PCB layouts and schematics designed for one part are directly compatible with the other.
