Description  
The Atmel® AT25320B/640B provides 32,768-/65,536-bits of Serial  
Electrically-Erasable Programmable Read-Only Memory (EEPROM) organized as  
4,096/8,192 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 AT25320B/640B is available in space-saving 8-lead  
JEDEC SOIC, 8-lead TSSOP, 8-lead UDFN, 8-lead XDFN, and 8-ball VFBGA  
packages.  
The AT25320B/640B 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.
