The AT25080A/160A/320A/640A provides 8192/16384/32768/65536 bits of serial electrically-erasable programmable read-only memory (EEPROM) organized as 1024/2048/4096/8192 words of 8 bits each. The device is optimized for use in many automotive applications where low-power and low-voltage operation are essential. The AT25080A/160A/320A/640A is available in space-saving 8-lead JEDEC SOIC and 8-lead TSSOP packages. The AT25080A/160A/320A/640A is enabled through the Chip Select pin (CS) and accessed via a three-wire interface consisting of Serial Data Input (SI), Serial Data Output (SO), and Serial Clock (SCK). All programming cycles are completely selftimed, and no separate erase cycle is required before write. Block write protection is enabled by programming the status register with one of four blocks of write protection. Separate program enable and program disable instructions are provided for additional data protection. Hardware data protection is provided via the WP pin to protect against inadvertent write attempts to the status register. The HOLD pin may be used to suspend any serial communication without resetting the serial sequence.
