The device density is indicated using bits and 2 of the status register. Page 31 Table No license, express or implied, by estoppel or otherwise, to any at45db642dd property right is granted by this document or in connection with the sale of Atmel products.

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.

Utilizing the RapidS To take advantage of the RapidS function’s ability to operate at higher clock frequencies, a full clock cycle must be used to transmit data back and forth across datsaheet serial bus. Please contact Atmel for the estimated availability of devices with the fix. The Block Erase function is not affected by the Chip Erase issue. Slave clocks out BYTE a first output byte. The busy status indicates that the Flash memory array and one of the buffers cannot be accessed; read and write operations to the other buffer can still be performed.
