Substitute Part Grouping Explanation

Substitution eligibility for the ATXMEGA192C3-AN is determined by strict equivalence across the following critical parameters:

• Manufacturer and Series: Both parts must be Microchip Technology AVR XMEGA C3 series devices
• Core Architecture: 8/16-Bit AVR processor
• Processing Speed: 32MHz operation
• Memory Configuration: 192KB flash (96K x 16), 2K x 8 EEPROM, 16K x 8 RAM
• I/O Count: 50 I/O pins
• Connectivity and Peripherals: Identical I2C, IrDA, SPI, UART/USART, USB, and peripheral feature set
• Package Footprint: 64-TQFP (14x14) surface mount
• Supply Voltage: 1.6V ~ 3.6V operating range
• Compliance: ROHS3 and REACH compliance maintained

The ATXMEGA192C3-AU qualifies as a direct substitute based on these parameters. Differences in packaging format (Tray vs. standard) and operating temperature range do not affect functional equivalence for applications within the overlapping temperature specification.

Parameter Comparison

Engineering Selection Recommendations

Both the ATXMEGA192C3-AN and ATXMEGA192C3-AU maintain active product status and full ROHS3 compliance with identical REACH status. Selection between these parts should be based on application-specific requirements:

The ATXMEGA192C3-AN supports an extended operating temperature range of -40°C to 105°C, making it suitable for applications requiring operation at elevated temperatures. The ATXMEGA192C3-AU operates within -40°C to 85°C and is supplied in Tray packaging, offering alternative supply chain options with higher current inventory availability (1950 units vs. 757 units).

For applications operating within the -40°C to 85°C range, either part provides functional equivalence. For applications requiring sustained operation above 85°C, the ATXMEGA192C3-AN is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are ATXMEGA192C3-AN and ATXMEGA192C3-AU pin-compatible?

A: Yes. Both devices use the 64-TQFP (14x14) package with identical pin assignments, I/O count (50), and functional connectivity. They are directly interchangeable at the PCB level.

Q: What is the difference between these two part numbers?

A: The primary differences are operating temperature range and packaging format. The ATXMEGA192C3-AN operates from -40°C to 105°C, while the ATXMEGA192C3-AU operates from -40°C to 85°C. The ATXMEGA192C3-AU is supplied in Tray packaging.

Q: Can I use ATXMEGA192C3-AU in an application designed for ATXMEGA192C3-AN?

A: Substitution is valid only if your application operates within the -40°C to 85°C temperature range. If sustained operation above 85°C is required, the ATXMEGA192C3-AN must be used.

Q: Are there any firmware or software compatibility issues between these parts?

A: No. Both devices share identical core architecture, memory configuration, and peripheral feature sets. Firmware compiled for one part executes identically on the other.

Q: Do both parts meet the same compliance standards?

A: Yes. Both ATXMEGA192C3-AN and ATXMEGA192C3-AU are ROHS3 compliant and REACH unaffected, with identical MSL ratings of 3 (168 Hours).
