DS1624

Digital Thermometer and Memory

General Description

The DS1624 consists of two separate functional units: a

256-byte nonvolatile E2 memory and a direct-to-digital

temperature sensor.

The nonvolatile memory is made up of 256 bytes of E2

memory. This memory can be used to store any type of

information the user wishes. These memory locations are

accessed through the 2-wire serial bus.

The direct-to-digital temperature sensor allows the

DS1624 to measure the ambient temperature and report

the temperature in a 12-bit word with 0.0625°C resolu-

tion. The temperature sensor and its related registers are

accessed through the 2-wire serial interface. Figure 1

shows a block diagram of the DS1624.
