Description  
The Atmel® AT34C04 is a 1.7V rated minimum operating voltage Serial EEPROM  
device containing 4096-bits of Serially Electrically Erasable and Programmable Read-  
Only Memory (EEPROM) organized as 512-bytes of eight bits each. The Serial  
EEPROM operation is tailored specifically for DRAM memory modules with Serial  
Presence Detect (SPD) to store a module’s vital product data such as the module’s  
size, speed, voltage, data width, and timing parameters.  
The AT34C04 is protocol compatible with the legacy JEDEC EE1002 specification  
(2-Kbit) devices enabling the AT34C04 to be utilized in legacy applications without any  
software changes. The device is designed to respond to specific software commands  
that allow users to identify and set which half of the memory the internal address  
counter is located. This special page addressing method to select the upper or lower  
half of the Serial EEPROM is what facilitates legacy compatibility. However, there is  
one exception to the legacy compatibility as the AT34C04 does not support the  
Permanent Write Protection feature.  
Additionally, the AT34C04 incorporates a Reversible Software Write Protection  
(RSWP) feature enabling the capability to selectively write protect any or all of the four  
128-byte quadrants. Once the RSWP is set, it can only be reversed by sending a  
specific software command sequence.  
The AT34C04 supports the industry standard 2-wire I2C Fast-Mode Plus (FM+) serial  
interface allowing device communication to operate at up to 1MHz. A bus timeout  
feature is supported to help prevent system lock-ups. The AT34C04 is available in  
space saving SOIC, TSSOP, and UDFN packages.
