Organized as 256 x 80 bits, it stores serial numbers, calibration constants, or configuration data in a footprint that needs only one GPIO and one ground trace. The 1-Wire interface keeps PCB routing minimal — useful in space-constrained designs like sensor probes, battery packs, or accessory identification where a separate I²C or SPI bus is unavailable. Rated for -40°C to 85°C operation, it fits industrial equipment, outdoor telecom, and factory automation environments. ## Lifecycle and compliance The DS28EC20P+T carries an Active product status — no end-of-life notice, no last-time-buy window to track. ROHS3 compliant, so it passes EU material restrictions without an exemption. For a BOM line that needs a 1-Wire EEPROM today and for the next several years, this part has no discontinuation risk.","metaTitle":"DS28EC20P+T 20Kbit 1-Wire EEPROM, 6-TSOC, Active","metaDescription":"Maxim Integrated DS28EC20P+T 20Kbit non-volatile EEPROM with 1-Wire interface in 6-TSOC.
