Flash Serial-SPI 3.3V 4M-bit 30ns 28Pin SOIC
Description
The AT45DB041A is a 2.5-volt only, serial interface Flash memory suitable for in-system reprogramming. Its 4,325,376 bits of memory are organized as 2048 pages of 264 bytes each. In addition to the main memory, the AT45DB041A 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.
