Product details

What the DS28EC20P+ is and where it fits

The Maxim Integrated DS28EC20P+ is a 20Kbit serial EEPROM using the 1-Wire interface, organized as 256 pages of 80 bytes each. The single-pin 1-Wire protocol reduces I/O count to one data line plus ground, which simplifies cabling and PCB routing in space-constrained designs like sensor modules, accessory identification, or calibration-parameter storage. The non-volatile memory retains data through power loss, and the industrial temperature range (-40°C to 85°C) suits outdoor telecom, factory automation, and engine-bay environments.

Package and mounting

Housed in a 6-pin TSOC package with J-leads (6-SMD, J-Lead), the DS28EC20P+ is a surface-mount device. The J-lead footprint offers good solder-joint inspection access compared to a gull-wing, but the small body means the reflow profile needs attention — the TSOC's thermal mass is low, so a standard lead-free profile with a peak around 260°C works, but keep the ramp rate moderate to avoid tombstoning. The supplier device package is 6-TSOC.

Lifecycle and sourcing reality

ROHS3 compliant.
