AN200963 Migration from Micron® MT29F (1-2-4 Gb) to Cypress S34ML-1 (1-2-4 Gb) AN200963 details how to migrate designs from Micron MT29F NAND flash memory devices to Cypress S34ML-1 NAND flash memory devices. 1 Introduction This application note details how to migrate designs from Micron 1-Gb MT29F1G08, 2-Gb MT29F2G08, and 4-Gb MT29F4G08 NAND flash memory devices to Cypress 1-Gb S34ML01G1, 2-Gb S34ML02G1, and 4-Gb S34ML04G1 NAND flash memory devices, respectively. S34ML01G1/ S34ML02G1/ S34ML04G1 devices are 3.0-volt NAND flash memory manufactured with the 4x nm technology. Note: All the information provided in this guide illustrates only the differences for each section. See the respective data sheets for more information. Cypress S34ML-1 NAND flash family devices are compatible with the Micron MT29F NAND flash family devices with respect to: 2 Block, page, byte size architecture JEDEC standard-compliant software command set Feature Comparison Most of the features of S34ML-1 and MT29F are similar, except for a few differences that are highlighted in Table 1. See the respective Micron MT29F and Cypress S34ML-1 data sheets to verify any other features. Table 1.
