Features: brand new and high quality In addition to the main memory, the AT45DB081E also contains two SRAM buffers of 256/264 bytes each. The buffers allow receiving of data while a page in the main memory is being reprogrammed. 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 E2 PROM emulation (bit or byte alterability) can be easily handled with a self-contained three step read-modify-write operation. The AT45DB081E also supports the RapidS serial interface for applications requiring very high speed operation. Its 8,650,752 bits of memory are organized as 4,096 pages of 256 bytes or 264 bytes each. The AT45DB081E is a 1.7V minimum, serial-interface sequential access Flash memory ideally suited for a wide variety of digital voice, for image, program code, and data storage applications. Uses a serial interface to sequentially access its data. The simple sequential access dramatically reduces active pin count, facilitates simplified hardware layout, increases system reliability, minimizes switching noise, and reduces package size.
