AT45DB021E-SHN-B - Brand New Adesto Technologies Memory
-
Description
The AT45DB021E-SHN-B is a 2.7-volt only, serial interface Flash memory suitable for in-system reprogramming. With 2,162,688 bits of memory, it is organized as 1024 pages of 264-bytes each. It also contains two SRAM data buffers of 264-bytes each, allowing the receiving of data while a page in the main memory is being reprogrammed. Unlike conventional Flash memories, the AT45DB021E-SHN-B uses a serial interface to sequentially access its data.
