1-megabit 2.7-volt Only DataFlash AT45DB011B
Description
The AT45DB011B is a 2.7-volt only, serial interface Flash memory 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. In addition to the main memory, the AT45DB011B also contains one SRAM data buffer of 264 bytes. The buffer allows receiving of data while a page in the main memory is being reprogrammed. EEPROM emulation (bit or byte alterability) 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 SPI serial interface……
