Description
The Atmel® AT25080B/160B provides 8,192/16,384 bits of Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as 1,024/2,048 words of 8 bits each. The device is optimized for use in many industrial and mercial applications where low-power and low-voltage operation are essential. The AT25080B/160B is available in space-saving 8-lead JEDEC SOIC, 8-lead TSSOP, 8-pad UDFN, 8-pad XDFN, 8-ball VFBGA, and 8-ball WLCSP packages. The AT25080B/160B 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 pletely 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 munication without resetting the serial sequence.
