W25M02GWTBIT集成電路（IC）的存儲(chǔ)器規(guī)格書PDF中文資料

GENERAL DESCRIPTIONS

The W25M02GW (2 x 1G-bit) Serial MCP (Multi Chip Package) Flash memory is based on the W25N Serial SLC NAND SpiFlash? series by stacking two individual W25N01GW die into a standard 8-pin package. It offers the highest memory density for the low pin-count package, as well as Concurrent Operations in Serial Flash memory for the first time. The W25M SpiStack? series is ideal for small form factor system designs, and applications that demand high Program/Erase data throughput. All W25N SpiFlash family devices are offered in space-saving packages which were impossible to use in the past for the typical NAND flash memory.
