AT30TS/TSE00x Devices
In addition to DDR3 and DDR4 DIMM applications, the Atmel AT30TS/TSE00x devices are ideal solutions for any application
that requires high levels of safety and reliability and a reduced risk of overheating — with the added benefit of an integrated,
robust 2Kb or 4Kb serial EEPROM to store customer preference data. In many cases, the AT30TS/TSE00x devices can drop
in and replace an existing low-density I

C serial EEPROM while offering the value-added security of real-time temperature
monitoring to enhance safety and reliability of the product.
