DS35X2GAXXX is a 256Mx8bit with spare 8Mx8 bit capacity.
The device is offered in 3.3/1.8 Vcc Power Supply,and with SPI interface.
The memory is divided into blocks that can be erased independently so it is possible to preserve valid data while old data is erased.
The device contains 2048 blocks,composed by 64 pages consisting in two NAND structures of 32 series connected Flash cells.Program operation allows the 2112-byte page writing in typical 300us and an erase operation can be performed in typical 2 ms on a 128K-byte block.Data in the page can be read out at 10ns cycle time per word.The on-chip Program/Erase Controller automates all program and erase functions including pulse repetition,where required,and internal verification and margining of data
