Description

The AT45DB021B is a 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 2,162,688 bits of memory are organized as 1024 pages of 264 bytes each. In addi-

tion to the main memory, the AT45DB021B also contains two SRAM data buffers

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

ory is being reprogrammed, as well as reading or writing a continuous data stream.
