General Description
The DS1624 consists of two separate functional units: a
256-byte nonvolatile E
2
memory and a direct-to-digital
temperature sensor.
The nonvolatile memory is made up of 256 bytes of E
2
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.
