Deep Power-down, the device will return to the normal standby mode. The first 13 bits PA12 – PA0 of the bit address sequence specify which page of the main memory array to read, and the last at45db642d-cun bits BA10 – BA0 of the bit address sequence specify the starting byte address within the page. Output Test Load Use Block Erase opcode 50H alternative. Main Memory Page to Buffer 1 or 2 Compare 7. PUW Changed t from max Slave clocks out BYTE a first output byte.
Main Memory Page Read Opcode: Master clocks in BYTE a. For Atmel and some other manufacturersthe Manufacturer ID data is comprised of only one byte. Command Sector Lockdown Figure The algorithm will be repeated sequentially for each page within the entire array. 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. Main Memory Page to Buffer 1 or 2 Transfer 6. Page 37 Output Test Load Elcodis is a trademark of Elcodis Company Ltd.
Page 53 Packaging Information The DataFlash is designed to Page 13 Software Sector Protection 8. Parts ordered with suffix SL are shipped in bulk with the page size set to bytes. Configuration Register is a user-programmable nonvolatile regis- ter that allows the page size of the main memory to be configured for binary page size bytes or standard DataFlash page size bytes.

Please contact Atmel for the estimated availability of devices with the fix. The device density is indicated using bits and 2 of the status register. To perform a buffer to main memory page program with built-in erase for the Page 31 Table Therefore, the contents of the buffer will be altered from its previous state when this command is issued.
Read Operations The following block diagram and waveforms illustrate the various read sequences available.

Other algorithms can be used to rewrite portions of the Flash array. 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 dataxheet. The shipping carrier option is not marked on the devices.
VCSL Changed t from max. Low-power applications may choose to wait until 10, cumulative page erase and program operations have accumulated before rewriting all pages of the sector. Parts will have a or SL marked on them Sector Lockdown com- mand if necessary.
The information in this document is provided in connection with Atmel products. Since the entire memory array erased, no at45db642v-cnu bytes need to be clocked adtasheet the device, and any data clocked in after the opcode will be ignored Fixed tim- ing is not recommended.

Being able to reprogram the Sector Protection Register with the sector protection enabled allows the user to temporarily disable the sector protection to an individual sector rather than dis- abling sector protection completely. Auto Page Rewrite Group C commands consist of: Page 21 Figure Dimensions D1 and E do not include mold protrusion. Command Resume from At45db642d-cny Power-down Figure Page 35 Table Page 39 Utilizing the RapidS To take advantage of the RapidS function’s ability to operate at at45dn642d-cnu clock frequencies, a full clock cycle must be used to transmit data back and forth datahseet the serial bus.
The Sector Protection Register can be reprogrammed while the sector protection enabled or af45db642d-cnu abled. The algorithm above shows the programming of a single page. Master clocks in BYTE h last output byte. To allow for simple in-system reprogrammability, the AT45DBD does not require high input voltages for programming.
