Product Summary

The AT45DB011B-SU is a 2.7-volt only, serial interface Flash memory. The AT45DB011B-SU is ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. Its 1,081,344 bits of memory are organized as 512 pages of 264 bytes each. Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the DataFlash uses a SPI serial interface to sequentially access its data. SPI mode 0 and mode 3 are supported.
