Micron — Memory Part Number Decoder [new]

“RC” is a package designator. “R” often stands for a 78-ball BGA (for x16 DDR4), while “C” may specify the ball map or lead-free status. Other letters indicate different ball counts or package types (e.g., “U” for 96-ball BGA). This field ensures physical compatibility with PCB footprints.

Micron memory part numbers can feel like trying to solve a puzzle, but once you know the "key," it's actually quite simple. Micron uses a standardized naming convention where each character in the string represents a specific technical attribute of the component. The Basic Structure micron memory part number decoder

A typical component part number (e.g., ) follows this general template: Prefix MT Micron Technology. Product Family 40 Technology type (40=DDR4, 62=LPDDR5, 41=DDR3). Voltage A Operating voltage (A=1.2V, F=1.1V for LPDDR5). Configuration 1G8 Density and width (e.g., 1 Gig x 8). Package Code SA Physical package type and lead-free status. Speed Grade -062E Maximum clock frequency or data rate. Temp / Status IT Operating environment (IT=Industrial, AT=Automotive). Die Revision :E The design version of the silicon. DDR5 Module Part Numbering System - Micron Technology “RC” is a package designator

Micron makes memory chips for computers, phones, and servers. Each chip has a long string of letters and numbers printed on it. This text is called a part number. The Basic Structure A typical component part number (e
