Description

The AT25080A/160A/320A/640A provides 8,192/16,384/32,768/65,536 bits of

Serial Electrically-Erasable Programmable Read-only Memory (EEPROM)

organized as 1,024/2,048/4,096/8,192 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 TSSOP packages.

The AT25080A/160A/320A/640A 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 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.
