Substitute Part Grouping Explanation

The ATXMEGA384C3-MH qualifies as a direct substitute for the ATXMEGA384C3-MN based on the following critical parameters:

All electrical specifications are identical: both devices feature the same AVR core processor, 8/16-bit architecture, 32MHz clock speed, 384KB FLASH memory, 32KB RAM, 4KB EEPROM, 1.6V to 3.6V supply voltage range, 16x12-bit analog-to-digital converters, 50 I/O pins, and identical connectivity options (I2C, IrDA, SPI, UART/USART, USB) with matching peripheral sets (Brown-out Detect/Reset, DMA, POR, PWM, WDT).

Both parts share the same physical package specification: 64-QFN (9x9) with exposed pad, classified as 64-VFQFN.

Both parts maintain identical compliance certifications: ROHS3 compliant, REACH unaffected, and MSL rating of 3 (168 Hours).

The primary difference between these parts is the packaging format: ATXMEGA384C3-MN is supplied in tube packaging, while ATXMEGA384C3-MH is supplied in tray packaging. Additionally, the operating temperature range for ATXMEGA384C3-MH extends to -40°C ~ 85°C, which is a subset of the ATXMEGA384C3-MN range of -40°C ~ 105°C.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Are ATXMEGA384C3-MN and ATXMEGA384C3-MH electrically identical?

A: Yes. Both parts feature identical core processor architecture, clock speed, memory configuration (384KB FLASH, 32KB RAM, 4KB EEPROM), I/O count, connectivity interfaces, and peripheral sets. They are functionally equivalent at the electrical level.

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

A: The primary differences are packaging format and operating temperature range. ATXMEGA384C3-MN is supplied in tube packaging with an operating temperature range of -40°C to 105°C. ATXMEGA384C3-MH is supplied in tray packaging with an operating temperature range of -40°C to 85°C.

Q: Can I use ATXMEGA384C3-MH as a substitute for ATXMEGA384C3-MN in all applications?

A: Substitution is valid for applications operating within the -40°C to 85°C temperature range. Applications requiring operation above 85°C must use ATXMEGA384C3-MN to ensure compliance with the specified operating temperature limits.

Q: Are the physical packages identical?

A: Yes. Both parts use the 64-QFN (9x9) package with exposed pad, classified as 64-VFQFN. PCB footprints and land patterns are identical, allowing direct substitution at the board level.

Q: Do these parts have the same compliance certifications?

A: Yes. Both ATXMEGA384C3-MN and ATXMEGA384C3-MH are ROHS3 compliant, REACH unaffected, and carry identical MSL ratings of 3 (168 Hours).

Q: Which part should I select for new designs?

A: Selection depends on application requirements. For applications within -40°C to 85°C, either part is suitable; tray packaging (ATXMEGA384C3-MH) may offer cost or supply advantages. For applications requiring extended temperature operation to 105°C, ATXMEGA384C3-MN is required.
