AT45DB321D General Description

DescriptionThe AT45DB321D is a 2.7-volt, serial-interface sequential access Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. The AT45DB321D supports RapidS serial interface for applications requiring very high speed operations. RapidS serial interface is SPI compatible for frequencies up to 66 MHz. Its 34,603,008 bits of memory are organized as 8,192 pages of 512 bytes or 528 bytes each. In addition to the main memory, the AT45DB321D also contains two SRAM buffers of 512/528 bytes each.
