Micron Memory Part Number Decoder Best

Micron FBGA and Part Marking Decoder is an essential technical utility for hardware engineers, repair technicians, and enthusiasts who need to identify specific memory chips. Because FBGA-packaged components are too small to fit a full marketing part number, Micron uses a shorthand 5-digit code (the "FBGA code") laser-marked on the chip. Key Features Abbreviation Translation

: It acts as a bridge between the physical marking on a chip (e.g., a five-digit alphanumeric string like "D9WFK") and the official Marketing Part Number (MPN) Data Sheet Access

: Once the full part number is retrieved, the tool often provides direct links to the relevant data sheets for technical specifications like voltage, density, and speed. Comprehensive Database

: The decoder covers a wide range of Micron products, including DRAM (DDR4, DDR5), NAND Flash, and SSD components. Ease of Use micron memory part number decoder

: The interface is straightforward—you simply enter the 5-digit code found on the chip (usually preceded by an "MT" mark) to get immediate results. : Using the official Micron FBGA Part Decoder

ensures you aren't relying on third-party spreadsheets or outdated forum posts. Cross-Compatibility

: It supports both active and obsolete part catalogs, making it useful for servicing legacy hardware. Limitations Package Dependency Micron FBGA and Part Marking Decoder is an

: The decoder is specifically for FBGA-packaged components. Standard modules (like DIMMs) typically use a Serial Presence-Detect (SPD) Lookup Mobile Experience

: While functional, the official tool is optimized for desktop technical use; identifying tiny laser marks on physical chips remains a manual, often difficult prerequisite. The Micron Part Number Decoder is a mission-critical tool

for anyone working at the component level. While casual consumers might find it overly technical, it is the only definitive way to verify the exact specifications of a Micron chip without secondary software. part numbering guide for a specific memory type (like DDR5 or NAND)?

Example decodes

• MT41K256M16HA‑125:

  • MT = Micron DRAM family
  • 4K256 = density/organization (example: 4 Gbit banks)
  • M16 = x16 data width
  • H = DDR3/DDR3L variant family code
  • A = package/revision
  • 125 = speed/latency grade

• MT29F2G08ABAEAWP‑IT:E (NAND example)

  • MT29 = Micron NAND family
  • F2G08 = 2 Gbit density, x8 organization
  • ABAEAWP = package, controller/feature string
  • IT = industrial temp
  • :E = encryption/secure feature

2. Speed codes are often backward.

-083E is faster than -093E because the number represents nanoseconds (lower = faster). For DDR4, -075 = 2666 MT/s (0.75ns cycle), -083 = 2400 MT/s.

3. Package and Revision (AZ)

• A: Indicates the die revision or manufacturing process generation.
• Z: Often denotes thermal or package specific options (e.g., lead-free, RoHS compliant, or standard vs. low-profile height).

Decoding Discrete DRAM Chips (Components)

If you have a bare Micron DRAM chip (like MT40A1G16RC-083E), the decoder differs slightly.

Example: MT40A1G16RC-083E

• MT40 = Base DRAM component family (DDR4)
• A = Generation / voltage (1.2V)
• 1G = 1 Gigabit per chip
• 16 = Organization (x16, meaning 16 I/O pins)
• RC = Package type (78-ball FBGA)
• 083E = Speed (DDR4-2400, 083 = 0.833ns cycle time)
• E = Halogen-free / lead-free

2. The Product Family (40A)

• 40A = DDR4
• 40C = DDR4 (3D stacking)
• 53E = DDR5
• 52B = LPDDR4
• 58C = LPDDR5
