1-Wire EEPROM for identity and calibration storage
The DS28E07P+T is a 1Kbit EEPROM from Analog Devices, organized as 256 x 4 bits and accessed over a single-contact 1-Wire interface. Its 2 µs access time and 3V to 5.25V supply range suit it for mixed-voltage designs, from 3.3V logic to legacy 5V systems.
Package and board-fit checklist
Housed in a 6-SMD J-Lead package (6-TSOC), the DS28E07P+T mounts flush to the PCB surface. The J-lead footprint is common among small serial EEPROMs and is hand-solderable for prototyping. The supplier device package is the 6-TSOC, a narrow-body SOIC-equivalent outline. Available on Tape & Reel or Cut Tape, the part is ready for both high-volume pick-and-place and low-quantity bench builds. ROHS3 compliance is confirmed on the datasheet, so it passes the standard EU material restriction gate for new designs.
