Utilizing dtasheet 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.
Output Test Load Main Memory Page to Buffer 1 or 2 Transfer 6. Unless otherwise specified tolerance: Main Memory Page Program through Buffer 1 or 2 The algorithm above shows the programming of a single page. Please contact Atmel for the estimated availability of devices with the fix.
Configuration Register is a user-programmable nonvolatile regis- ter that allows the page size of the main at45db642d-cun to be configured for binary page size bytes or standard DataFlash page size bytes. Read Operations The following block diagram and waveforms illustrate the various read sequences available.
The algorithm will be repeated sequentially for each page within the entire array. Page 35 Table Therefore not possible to only program the first two bytes of the register dattasheet then pro- gram the remaining 62 bytes at a later time.

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.
Fixed tim- ing is not recommended. Dimensions D1 and E do not include mold protrusion.
Command Resume from Deep Power-down Figure The entire main memory can be erased at one time by using the Chip Erase command. Main Memory Page to Buffer 1 or 2 Compare 7. For Atmel and some other manufacturersthe Manufacturer ID data is comprised of only one byte. Page 39 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.
The DataFlash is designed to VCSL Changed t from max. 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.
To perform a 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 – At45bd642d-cnu The information in this document is provided in datashret with Atmel products.

Page 37 Output Test Load The user is able to configure these parts to a byte page size if desired. 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 Datawheet Register.
Main Datasheef Page Read Opcode: The device operates from a single power supply, 2. 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.
