FLASH Memory Integrated Circuit IC Chip 64Mb 264 Bytes x 32K Pages SPI 85MHz 8 VDFN AT45DB641E-MWHN-T
AT45DB641E-MWHN-T FLASH Memory IC 64Mb (264 Bytes x 32K pages) SPI 85MHz 8-VDFN
Description
The AT45DB641E is a 1.7V minimum, serial-interface sequential access Flash memory ideally suited for a wide variety ofdigital voice, image, program code, and data storage applications. The AT45DB641E also supports the RapidS serial interface for applications requiring very high speed operation.
the AT45DB641E also contains two SRAM buffers of 256/264 bytes each. Interleaving between both buffers can dramatically increase a system's ability to write a continuous data stream. In addition, the SRAM buffers can be used as additional system scratch pad memory, and E2PROM emulation (bit or byte alterability) can be easily handled with a self-contained three step read-modify-write operation.
