Description  
The Atmel® AT25010B/020B/040B provides 1,024/2,048/4,096 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.
