DS28EA00 - 1-Wire Digital Thermometer

Description

The DS28EA00 is a digital thermometer with 9-bit (0.5°C) to 12-bit (1/16°C) resolution and alarm function with nonvolatile (NV), user-programmable upper and lower trigger points.

Each DS28EA00 has its own unique 64-bit registration number that is factory programmed into the chip.

Features

  • Digital Thermometer Measures Temperatures from -40°C to +85°C.
  • Thermometer Resolution is User Selectable from 9 to 12 Bits.
  • Unique 1-Wire Interface Requires Only One Port Pin for Communication.
  • Each Device Has a Unique 64-Bit, FactoryLasered Registration Number.
  • Multidrop Capability Simplifies Distributed Temperature-Sensing.

DS28EA00 1-Wire Digital Thermometer with Sequence Detect and PIO General Description The DS28EA00 is a digital thermometer with 9-bit (0.5°C) to 12-bit (1/16°C) resolution and alarm function with nonvolatile (NV), user-programmable upper and lower trigger points. Each DS28EA00 has its own unique 64-bit registration number that is factory programmed into the chip. Data is transferred serially through the 1-Wire® protocol, which requires only one data line and a ground reference for communication. The improved 1-Wire front-end with hysteresis and glitch filter enables the DS28EA00 to perform reliably in large 1-Wire networks.
