AT45DB041D-SU

Product Summary

The AT45DB041D-SU is a 2.5V or 2.7V, serial-interface Flash memory ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. The AT45DB041D-SU supports RapidS serial interface for applications requiring very high speed operations. RapidS serial interface is SPI compatible for frequencies up to 66 MHz. Its 4,325,376 bits of memory are organized as 2,048 pages of 256 bytes or 264 bytes each. In addition to the main memory, the AT45DB041D-SU also contains two SRAM buffers of 256/264 bytes each. The buffers of the AT45DB041D-SU allow the receiving of data while a page in the main Memory is being reprogrammed, as well as writing a continuous data stream. EEPROM emulation (bit or byte alterability) of the AT45DB041D-SU is easily handled with a self-contained three step read-modify-write operation. Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the DataFlash uses a RapidS serial interface to sequentially access its data. The simple sequential access dramatically reduces active pin count, facilitates hardware layout.
