ATXMEGA16D4-MN Equivalent & Substitute Parts

Part Overview

The ATXMEGA16D4-MN is an AVR XMEGA D4 microcontroller manufactured by Microchip Technology, featuring 8/16-bit processing capability, 16KB FLASH memory, and 32MHz operation. This device is actively produced and widely used in embedded applications requiring moderate processing power with integrated connectivity options including I2C, IrDA, SPI, and UART/USART interfaces.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when alternative packaging formats are required for manufacturing processes, or when inventory constraints necessitate sourcing from alternative stock positions.

Substitute Part Grouping Explanation

Substitution of the ATXMEGA16D4-MN is determined by strict equivalence across the following critical parameters:

• Core processor architecture (AVR)
• Core size (8/16-Bit)
• Operating frequency (32MHz)
• Memory configuration (16KB FLASH, 1K x 8 EEPROM, 2K x 8 RAM)
• Voltage supply range (1.6V ~ 3.6V)
• I/O count (34 pins)
• Connectivity interfaces (I2C, IrDA, SPI, UART/USART)
• Peripheral feature set (Brown-out Detect/Reset, POR, PWM, WDT)
• Package form factor (44-VQFN with 7x7mm dimensions)
• Series designation (AVR® XMEGA® D4)

The ATXMEGA16D4-MH qualifies as a direct substitute based on identical electrical specifications and package geometry. Differences are limited to packaging format (Tray versus standard packaging) and operating temperature range specification.

Parameter Comparison

Engineering Selection Recommendations

Both the ATXMEGA16D4-MN and ATXMEGA16D4-MH maintain Active product status from Microchip Technology and carry identical RoHS3 compliance and REACH unaffected designations. Both devices meet the same moisture sensitivity level (MSL 3) and thermal specifications for standard operating conditions.

The ATXMEGA16D4-MH is manufacturer-recommended as a substitute and is verified as programmable through DiGi-Electronics channels. The primary distinction is the operating temperature range, where the ATXMEGA16D4-MN supports extended operation to 105°C while the ATXMEGA16D4-MH is specified to 85°C. Selection between these parts depends on application temperature requirements. For applications operating within the -40°C to 85°C range, either part is functionally equivalent. For applications requiring operation above 85°C, the ATXMEGA16D4-MN is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are ATXMEGA16D4-MN and ATXMEGA16D4-MH pin-compatible?

A: Yes. Both devices use the 44-VQFN (7x7mm) package with identical pin assignments, I/O configuration (34 pins), and electrical characteristics. They are directly interchangeable at the PCB level.

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

A: The primary differences are packaging format (Tray for ATXMEGA16D4-MH) and maximum operating temperature specification (105°C for ATXMEGA16D4-MN versus 85°C for ATXMEGA16D4-MH). All electrical and functional parameters are identical.

Q: Can I use ATXMEGA16D4-MH in an application designed for ATXMEGA16D4-MN?
