... The AT25080/160/320/640 is available in space saving 8-lead PDIP, 8- lead JEDEC SOIC and 14-lead TSSOP packages. The AT25080/160/320/640 is enabled through the Chip Select pin (CS) and accessed via a 3-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). All programming cycles are completely self-timed, and no sepa- rate ERASE cycle is required before WRITE ...

... The WP pin function is blocked when the WPEN bit in the status register is “0”. This will allow the user to install the AT25080/160/320/640 in a system with the WP pin tied to ground and still be able to write to the status register. All WP pin functions are enabled when the WPEN bit is set to “ ...

... Description The AT25080/160/320/640 utilizes an 8-bit instruction register. The list of instructions and their operation codes are contained in Table 1. All instructions, addresses, and data are transferred with the MSB first and start with a high-to-low CS transition. ...

... WRITE STATUS REGISTER (WRSR): The WRSR instruction allows the user to select one of four levels of protection. The AT25080/160/320/640 is divided into four array segments. One quarter (1/4), one half (1/2), or all of the memory segments can be protected. Any of the data within any selected segment will therefore be READ only. The block write protection levels and corresponding status register control bits are shown in Table 4 ...

... WRITE cycle has ended. Only the READ STATUS REGISTER instruction is enabled during the WRITE programming cycle. The AT25080/160/320/640 is capable of a 32-byte PAGE WRITE operation. After each byte of data is received, the five low order address bits are internally incremented by one; the high order bits of the address will remain constant ...
