Description The AT45D081A is a 5-volt only, serial interface Flash memory suitable for in-system reprogramming. Its 8,650,752 bits of memory are organized as 4096 pages of 264 bytes each. In addition to the main memory, the AT45D081A also contains two SRAM data buffers of 264 bytes each. The buffers allow receiving of data while a page in the main memory is being reprogrammed. Unlike conventional Flash (continued) Pin Configurations Pin Name CS SCK SI SO WP RESET RDY/BUSY Function Chip Select Serial Clock Serial Input Serial Output Hardware Page Write Protect Pin Chip Reset Ready/Busy PLCC CS NC NC GND VCC NC NC GND NC NC CS SCK SI SO NC NC NC NC NC NC……
