AT45DB021B-RI规格书详情
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 addition 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 memory is being reprogrammed, as well as reading or writing a continuous data stream.
