OVERVIEW
A block diagram of the DS1624 is shown in Figure 1. The DS1624 consists of two separate functional
units: 1) a 256–byte nonvolatile E
The nonvolatile memory is made up of 256 bytes of E
type of information the user wishes; for example, frequency compensation coefficients may be placed in
this memory to allow for compensation of measured frequency depending upon the temperature at which
the measurement is made. 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 value in a 13–bit word, with 0.03125°C resolution. The temperature sensor and its
related registers are accessed through the 2–wire serial interface.
