Description

AT45DB081B

The AT45DB081B is a 2.5-volt or 2.7-volt only, serial interface Flash memory ideally

suited for a wide variety of digital voice-, image-, program code- and data-storage

applications. Its 8,650,752 bits of memory are organized as 4096 pages of 264 bytes

each. In addition to the main memory, the AT45DB081B also contains two SRAM

data buffers of 264 bytes each. The buffers allow receiving of data while a page in the

main memory is being reprogrammed, as well as reading or writing a continuous data
