Sector Lockdown com- mand if necessary. To perform a contin- uous read with the page size set to bytes, the opcode, 03H, must be clocked into at45cb642d-cnu device followed by three address bytes A22 – A The status of whether or not sector protection has been enabled or disabled by either the software or the hardware controlled methods can be deter- mined by checking the Status Register.

Page 35 Table 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 the serial bus.

Unless otherwise specified tolerance: Use Block Erase opcode 50H alternative. Output Test Load Dimensions D1 and E do not include mold protrusion. The device density is indicated using bits and 2 of the status register.

Page 31 Table The entire main memory can be erased at one time by using the Chip At445db642d-cnu command.


Master clocks in BYTE a. To perform a buffer to main memory page program with built-in at45ddb642d-cnu for the 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.

Standard parts are shipped with the page size set to bytes. The Block Erase function is not affected by the Chip Erase issue. Manufacturer ID codes that are two, three or even four bytes long with the first byte s in the sequence being 7FH.

Page 37 Output Test Load Fixed tim- ing is not recommended. Deep Power-down, the device will return to the normal standby mode. Reading the Sector Lockdown Register The Sector Lockdown Register can be at45d6b42d-cnu to determine which sectors in the memory array are permanently locked down.

Please contact Atmel for the estimated availability of devices with at54db642d-cnu fix. Auto Page Rewrite Group C commands consist of: To allow for simple in-system reprogrammability, the AT45DBD does not require high input voltages for programming. Slave clocks out BYTE a first output byte.

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.

The surface finish of the package shall datasheeet EDM Charmille Page 13 Software Sector Protection 8. 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 Read Operations The following block diagram and waveforms illustrate the various read sequences available.

Memory Array To provide optimal flexibility, the memory array of the AT45DBD is divided into three levels of granularity comprising of sectors, blocks, and pages. The Sector Protection Register can be reprogrammed while the sector protection enabled or dis- abled. Main Memory Page Program through Buffer 1 or 2 Page 39 Utilizing the RapidS To take advantage of the RapidS function’s ability to operate at higher clock at45db6422d-cnu, a full clock cycle must be used to transmit data back and forth across the serial bus.

Master clocks in BYTE h last output byte. Since the entire memory array erased, no address bytes need to be clocked into the device, at45db642d-nu any data clocked in after the opcode will be ignored
