Description
The AT45DB161D is a 2.5V or 2.7V, serial-interface sequential access Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. The AT45DB161D supports RapidS serial interface for applications requiring very high speed operations. RapidS serial interface is SPI compatible for frequencies up to 66MHz. Its 17,301,504-bits of memory are organized as 4,096 pages of 512-bytes or 528-bytes each. In addition to the main memory, the AT45DB161D also contains two SRAM buffers of 512-/528-bytes each. The buffers allow the receiving of data while a page in the main Memory is being reprogrammed, as well as writing a continuous data stream.
