AT45DB161D-TU

Product Summary

The AT45DB161D-TU is a 2.5-volt or 2.7-volt, serial-interface sequential access Flash memory. It is ideally suited for a wide variety of digital voice-, image-, program code- and data-storage applications. The AT45DB161D-TU supports RapidS serial interface for applications requiring very high speed operations. RapidS serial interface is SPI compatible for frequencies up to 66 MHz. Its 17,301,504 bits of memory are organized as 4,096 pages of 512 bytes or 528 bytes each. In addition to the main memory, the The AT45DB161D-TU also contains two SRAM buffers of 512/528 bytes each. Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the AT45DB161D-TU uses a RapidS serial interface to sequentially access its data.
