Product details

The Maxim Integrated DS28EC20P+T is a 20Kbit non-volatile EEPROM communicating over a single-contact 1-Wire® bus. 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.

ROHS3 compliant, so it passes EU material restrictions without an exemption.

Frequently asked questions

How to program DS28EC20P+T?

The 1-Wire interface uses a single data line plus ground. A standard 1-Wire master (GPIO bit-bang or dedicated controller) writes and reads the 256 x 80 array. No external programming voltage is needed — the EEPROM is written from the 1-Wire bus power.

Is DS28EC20P+T RoHS compliant?

Yes — rated ROHS3 Compliant, covering all six original RoHS substances plus the four phthalates. No RoHS exemption required.
