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.
