Its 1,081,344 bits of memory are organized as 512 pages of 264 bytes each. In addition to the main memory, the AT45D011 also contains one SRAM data buffer of 264 bytes. Unlike conventional Flash memories that are accessed randomly with multiple address lines and a parallel interface, the DataFlash uses a Pin Configurations Pin Name CS SCK SI Function Chip Select Serial Clock Serial Input SOIC (continued) SI 1 SCK 2 RESET 3 CS 4 8 SO 7 GND 6 VCC 5 WP SO Serial Output WP Hardware Page Write Protect Pin RESET Chip Reset RDY/BUSY Ready/Busy PLCC TSSOP Top View Type 1 4 CS 3 NC 2 NC 1 GND 32 VCC 31 NC 30 NC SCK 5 SI 6 SO 7 NC 8 NC 9 NC 10 NC 11 NC 12 NC 13 29 WP 28 RES...
