Description

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 PDIP and 8-lead

JEDEC SOIC 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 self-

timed, 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.
