1-Wire EEPROM in a 16-SOIC — what the 2 µs access means for the bus
The DS28E04S-100+ is a 4Kbit non-volatile EEPROM from Analog Devices, accessed over a single-contact 1-Wire interface. Organized as 256 x 16 bits, it delivers a 2 µs access time — fast enough for the 1-Wire bus master to read a page in a single time slot without stretching the protocol timing. The 1-Wire interface carries both data and power on one line, so the part needs only a parasitic-supply capacitor and a pull-up resistor on the bus — no separate VCC trace.
Package and board-fit: 16-SOIC narrow-body
The supplier device package is 16-SOIC — a single part number covers the full layout, no thermal pad or exposed paddle to plan for. Shipping in Tube format — the rails protect the leads during handling, but the narrow SOIC body means the tube may not share a feeder with wider SOIC-16 variants. Confirm the tube orientation matches your pick-and-place tape-out before loading.
Because the part is in active manufacture, supply is through the standard Analog Devices channel.
