1. Description

The AT45DB081D 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 AT45DB081D supports RapidS serial interface for applications requiring very

high speed operations. RapidS serial interface is SPI compatible for frequencies up to

66 MHz. Its 8,650,752 bits of memory are organized as 4,096 pages of 256 bytes or

264 bytes each. In addition to the main memory, the AT45DB081D also contains two

SRAM buffers of 256/264 bytes each. The buffers 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) is easily handled with a self-

contained three step read-modify-write operation. Unlike conventional Flash memo-

ries that are accessed randomly with multiple address lines and a parallel interface,
