Description

The Atmel^®AT25010B/020B/040B provides 1024/2048/4096 bits of Serial

Electrically Erasable Programmable Read-Only Memory (EEPROM) organized as

128/256/512 words of 8 bits each. The device is optimized for use in many

industrial and commercial applications where low-power and low-voltage

operation are essential. The AT25010B/020B/040B is available in space saving,

JEDEC SOIC, UDFN, TSSOP, XDFN, and VFBGA packages.

The AT25010B/020B/040B 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. The

HOLD pin may be used to suspend any serial communication without resetting the

serial sequence.
