Product Overview

The AT45DB321D 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 AT45DB321D supports the RapidS serial interface for applications requiring very high speed operations. The RapidS serial interface is SPI compatible for frequencies up to 66MHz. The 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. These buffers allow the receiving of data while a page in the main memory is being reprogrammed, as well as the writing of a continuous data stream. EEPROM (electrically erasable and programmable read-only memory) emulation (bit or byte alterability) is easily handled with a self-contained, three-step read-modify-write operation.
  • 66MHz maximum clock frequency
  • User configurable page size
  • Page program operation
  • Flexible erase options
  • Two SRAM data buffers (512/528 bytes)
  • Continuous read capability through entire array
  • Low power dissipation
  • Hardware and software data protection features
  • Sector lockdown for secure code and data storage
  • Security: 128 byte security register
  • 100,000 program/erase cycles per page min.
  • Data retention: 20 years

Applications

Consumer Electronics, Embedded Design & Development, Imaging, Video & Vision, Multimedia, Portable Devices
