It is catalogued under DC-DC Power Modules but functions as a non-volatile memory for calibration constants, serialization data, or configuration parameters in a power supply or module. Operates from 2.8V to 6V, covering common 3.3V and 5V rails with margin. ## Memory technology and field programming OTP EPROM technology means each bit is programmed once, permanently. The 128 x 8 organization allows byte-level writes during manufacturing or depot-level programming, but no field updates. This is the right choice when the stored data must never change after final test. The 1.27mm pitch is routable on a two-layer board with standard soldering profiles.","metaTitle":"Analog Devices DS2502S+ EPROM, 1Kbit, 1-Wire, 8-SOIC","metaDescription":"DS2502S+ 1Kbit OTP EPROM with 1-Wire interface, 2.8-6V supply, -40 to +85°C.
