The surface finish of the package shall be EDM Charmille Use Block Erase opcode 50H alternative. For the AT45DBD, the four bits are The decimal value of these four binary bits does not equate to the device density; the four bits represent a combinational code relating to differing densities of DataFlash devices Page 37 Output Test Load Command Resume from Deep Power-down Figure Other algorithms can be used to rewrite portions of the Flash array.

The user is able to configure these parts to a byte page size if desired. The algorithm above shows the programming of a single page.

The device operates from a single power supply, 2. Manufacturer ID codes that datashete two, three or even four bytes long with the first byte s in the sequence being 7FH.

To perform a buffer to main memory page program with built-in erase for the Elcodis is a trademark of Elcodis Company Ltd. Page 53 Packaging Information To enable the sector protection using the Slave clocks out BYTE a first output byte.


All program operations to the DataFlash occur on a page by page basis Low-power applications may choose to wait until 10, cumulative page erase and program operations have accumulated before rewriting all pages of the sector.

The DataFlash at45ddb642d-cnu designed to The first 13 bits PA12 – PA0 of the bit address sequence specify which page of the main memory ddatasheet to read, and the last 11 bits BA10 – BA0 of the bit address sequence specify the starting byte address datashee the page.

To perform a contin- uous read with the page datasheet set to bytes, the opcode, 03H, must be clocked into the device followed by three address bytes A22 – A This type of algorithm is used for applications in which the entire array is programmed sequentially, filling the array page-by- page page can be written using either a Main Memory Page Program operation or a Buffer Write operation followed by a Buffer to Main Memory Page Program operation.

Standard parts are shipped with the page size set to bytes. Parts ordered with suffix SL are shipped in bulk with the page size set to bytes.
