Parameter Comparison

Engineering Selection Recommendations

Both the ATXMEGA32C4-MN and ATXMEGA32C4-MH maintain Active product status from Microchip Technology and comply with ROHS3 and REACH requirements. The primary distinction between these parts is packaging configuration and operating temperature range.

The ATXMEGA32C4-MN provides a 64-QFN (9x9) package with extended operating temperature range to 105°C, suitable for applications requiring higher thermal tolerance or maximum I/O pin count.

The ATXMEGA32C4-MH provides a 44-VQFN (7x7) package with operating temperature range to 85°C, suitable for applications with reduced I/O requirements or space constraints. This variant is available in Tray packaging format.

Selection between these parts depends on PCB layout requirements, thermal environment specifications, and I/O pin utilization in the target application.

Frequently Asked Questions (FAQ)

Q: Can ATXMEGA32C4-MH be used as a direct replacement for ATXMEGA32C4-MN?

A: Functional substitution is possible only if the application design accommodates the reduced pin count of the 44-VQFN package. The 44-pin configuration provides fewer I/O pins than the 64-pin configuration. Core processor functionality, memory configuration, and electrical specifications remain identical.

Q: What is the difference in pin count between these packages?

A: The ATXMEGA32C4-MN uses a 64-QFN (9x9) package, while the ATXMEGA32C4-MH uses a 44-VQFN (7x7) package. The 64-pin variant provides 34 I/O pins across a larger footprint, while the 44-pin variant also provides 34 I/O pins in a smaller footprint.

Q: Are there thermal operating range differences?

A: Yes. The ATXMEGA32C4-MN operates from -40°C to 105°C, while the ATXMEGA32C4-MH operates from -40°C to 85°C. Applications requiring operation above 85°C must use the ATXMEGA32C4-MN variant.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ATXMEGA32C4-MN and ATXMEGA32C4-MH are ROHS3 Compliant, REACH Unaffected, and maintain MSL 3 (168 Hours) moisture sensitivity classification.

Q: What packaging formats are available?

A: The ATXMEGA32C4-MN is supplied in standard packaging. The ATXMEGA32C4-MH is available in Tray packaging format.
