The 1-Wire protocol lets a microcontroller or dedicated master read the stored 128 bytes with a single GPIO pin. ## OTP memory: no field updates possible Because this is an OTP EPROM, every byte is written exactly once. That makes it a poor fit for firmware storage or any data that needs periodic revision — for those jobs, look at an EEPROM or Flash part on the same 1-Wire bus. But for a fixed serial number, a calibration coefficient table, or a one-time authentication key that must survive power loss and resist alteration, the DS2502P+ is exactly the right density at 1Kbit (128 x 8). ## Sourcing and lifecycle The DS2502P+ is listed as Active and ROHS3 compliant. No end-of-life notice or last-time-buy window is on record.","metaTitle":"DS2502P+ 1Kbit 1-Wire EPROM, OTP, -40°C to +85°C","metaDescription":"DS2502P+ 1Kbit EPROM with 1-Wire interface, OTP, 2.8V–6V supply, industrial temp range.
