Features: Brand new and high quality The AT45DB321E is a 2.3 V minimum, serial interface sequential access Flash memory ideal for a variety of digital voice, image, program code, and data storage applications. In addition to the main memory, the AT45DB321E also contains two SRAM buffers of 512/528 bytes each. The buffers allow reception of data while a page in the main memory is reprogrammed. Interleaving between both buffers can dramatically increase a system's ability to write a continuous data stream. The AT45DB321E also supports the RapidS serial interface for applications requiring very high-speed operation. Its 34,603,008 bits of memory are organized as 8,192 pages of 512 bytes or 528 bytes each. The device is optimized for use in many commercial and industrial applications where high density, low pin count, low voltage, and low power are critical. Uses a serial interface to sequentially access its data. The simple sequential access dramatically reduces the number of active pins, facilitates simplified hardware layout, increases system reliability, minimizes switching noise, and reduces package size.
