THERMOSTAT OUTPUT OPERATION Figure 3
OPERATION AND CONTROL
The DS1620 must have temperature settings resident in the TH and TL registers for thermostatic
operation. A configuration/status register also determines the method of operation that the DS1620 will
use in a particular application and indicates the status of the temperature conversion operation. The
configuration register is defined as follows:
CONFIGURATION/STATUS REGISTER
where
DONE = Conversion Done Bit. 1=conversion complete, 0=conversion in progress. The power-up/POR
state is a 1.
THF
= Temperature High Flag. This bit will be set to 1 when the temperature is greater than or equal
to the value of TH. It will remain 1 until reset by writing 0 into this location or by removing power from
the device. This feature provides a method of determining if the DS1620 has ever been subjected to
temperatures above TH while power has been applied. The power-up/POR state is a 0.
TLF
= Temperature Low Flag. This bit will be set to 1 when the temperature is less than or equal to
the value of TL. It will remain 1 until reset by writing 0 into this location or by removing power from the
device. This feature provides a method of determining if the DS1620 has ever been subjected to
temperatures below TL while power has been applied. The power-up/POR state is a 0.
NVB
= Nonvolatile Memory Busy Flag. 1=write to an E2 memory cell in progress. 0=nonvolatile
memory is not busy. A copy to E2 may take up to 10 ms. The power-up/POR state is a 0.
CPU
= CPU Use Bit. If CPU=0, the CLK/ CONV pin acts as a conversion start control, when RST is
low. If CPU is 1, the DS1620 will be used with a CPU communicating to it over the 3–wire port, and the
operation of the CLK/ CONV pin is as a normal clock in concert with DQ and RST . This bit is stored in
nonvolatile E2 memory, capable of at least 50,000 writes. The DS1620 is shipped with CPU=0.
