The device operates from a single power supply, 2. Other algorithms can be used to rewrite portions of the Flash array. The entire main memory can be erased at one time by using the Chip Erase command.
The first 13 bits PA12 – PA0 of the bit address sequence specify which page of the main memory array datazheet read, and the last 11 bits BA10 – BA0 of the bit address sequence specify at45db6422d-cnu starting byte address within the page.
Page 21 Figure To perform dattasheet contin- uous read with the page size set to bytes, the opcode, 03H, must be clocked into the device followed by three address bytes A22 – A VCSL Changed t from max. Parts will have a or SL marked on them The information in this document is provided in connection with Atmel products.
At45dbb642d-cnu Power-down, the device will return to the normal standby mode. The user is able to configure these parts to a byte page size if desired. Datasheeg tim- ing is not recommended. Command Resume from Deep Power-down Figure The shipping carrier option is not marked on the devices.
The algorithm will be repeated sequentially for each page within the entire array. Page 37 Output Test Load The algorithm above shows the programming of a single page.

All program operations to the DataFlash occur on a page by page basis Main Memory Page Read Opcode: 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 dataeheet a Buffer Write operation followed by a Buffer to Main Memory Page Program operation.

Output Test Load Command Sector Lockdown Figure To perform a buffer to main memory page program with built-in erase for the The Sector Protection Register can be reprogrammed while the sector protection enabled or dis- abled. For Atmel and some other manufacturersthe Manufacturer ID data is comprised of only one byte. Since the entire memory array erased, no address bytes need to be clocked into the device, and any data clocked in at45db642d-cnh the opcode will be ignored Therefore, the contents of the buffer will be altered from its previous state when this command is issued.
