The document describes a 4096-bit Electrically Erasable Programmable Read-Only Memory (EEPROM) with a unique 64-bit registration number, built-in multidrop controller, and wide voltage range.
The DS2433 is a 4 kb 1‑Wire EEPROM with a unique 64‑bit laser‑etched registration number that provides absolute identity. It includes a 256‑bit scratchpad, sixteen 256‑bit EEPROM pages, and a built‑in multidrop controller for use with other MicroLAN™ devices. Communication uses a single data pin at up to 16.3 kbps, with an Overdrive mode that reaches 142 kbps.
The device operates from a 2.8 V to 6.0 V supply over a temperature range of –40 °C to +85 °C and is available in low‑cost PR‑35 or 8‑pin SO surface‑mount packages. The handbook details the 1‑Wire protocol, memory function commands, parasite‑power operation, and provides full electrical characteristic tables.
