Part Model Electrical Guidelines for Electronic-Device Packages – XML Requirements	JEP30-E100G	Feb 2025
This standard establishes the requirements for exchanging part data between part manufacturers and their customers for electrical and electronic products. This standard applies to all forms of electronic parts. It forms part of the Part Model XML Schema, which covers the parental structure for the electrical, physical, Electrical, assembly process classification data along with materials and substances that may be present in the supplied product or subproducts. This Guideline specifically focuses on the “Electrical” sub-section of the Part Model. For more information visit the main JEP30 webpage.

LPDDR5/5X Serial Presence Detect (SPD) Contents Release Number: 1.0	JESD406-5A	Nov 2024
This publication describes the serial presence detect (SPD) values for all LPDDR5/5X memory modules. In this context, “modules” applies to memory modules like traditional Dual In-line Memory Modules (DIMMs) or solder-down motherboard applications. The SPD data provides critical information about all modules on the memory channel and is intended to be use by the system's BIOS in order to properly initialize and optimize the system memory channels. The storage capacity of the SPD non-volatile memory is limited, so a number of techniques are employed to optimize the use of these bytes, including overlays and run length limited coding.

DDR5 SDRAM Release Number: Version 1.31	JESD79-5C.01	Jul 2024
Version 1.31 This standard defines the DDR5 SDRAM specification, including features, functionalities, AC and DC characteristics, packages, and ball/signal assignments. The purpose of this Standard is to define the minimum set of requirements for JEDEC compliant 8 Gb through 32 Gb for x4, x8, and x16 DDR5 SDRAM devices. This standard was created based on the DDR4 standards (JESD79-4) and some aspects of the DDR, DDR2, DDR3, and LPDDR4 standards (JESD79, JESD79-2, JESD79-3, and JESD209-4). A list of RAND License Assurance/Disclosure Forms is available to JEDEC members on the restricted Members' website. Non-members may obtain individual Assurance/Disclosure forms by requesting them from the JEDEC office.

Low Power Double Data Rate 4 (LPDDR4)	JESD209-4E	Jun 2024
This document defines the LPDDR4 standard, including features, functionalities, AC and DC characteristics, packages, and ball/signal assignments. The purpose of this specification is to define the minimum set of requirements for a JEDEC compliant 16 bit per channel SDRAM device with either one or two channels. LPDDR4 dual channel device density ranges from 2 Gb through 32 Gb and single channel density ranges from 1 Gb through 16 Gb.
