Miguel,
You're going to want to reference the LH79520 card engine BOM for specific information for card engine flash. Once you have the manufacturer and a part number you'll be able to get datasheets and user's guide for the flash that is specific to your card engine. The BOM for the LH79520 can be found at the following link:
