LPDDR4X - 11 Timing Parameters - Formulas For Manual Calculation

Siddhartha — Thu, 01 Sep 2022 05:45:17 GMT

Hi !

I plan to make a new circuit board with the following components:

1. Processor: Intel Core i7-1185GRE

2. Memory (LPDDR4X): Micron MT53D1024M32D4

In the attached file, there are 11 timing parameters.

I would like to manually calculate the values of all these 11 parameters.

Where can I find a document / spreadsheet / web page that shows how to calculate them ?

Actually, the LPDDR4X memory component is Micron MT53D1024M32D4DT.

Here's what I've found so far:

S.No.	Timing Parameter	Source Where Value / Formula Is Found
1	tCL	LPDDR4X Datasheet
2	tCWL	https://media.s-bol.com/RLZ7Yvq5Gkl0/original.pdf (Page 109 of 585)
3	tFAW	LPDDR4X Datasheet
4	tRAS	Element14.com link. See link above this table.
5	tRCDtRP	Element14.com link. See link above this table.
6	tREFI	LPDDR4X Datasheet
7	tRFC	LPDDR4X Datasheet
8	tRRD	LPDDR4X Datasheet
9	tRTP	LPDDR4X Datasheet
10	tWR	LPDDR4X Datasheet
11	tWTR	LPDDR4X Datasheet

Please let me know if I've erred !
