information with leap year compensation and also pro-
vides an alarm interrupt. Temperature measurement is
provided via integrated thermal technology which can
measure temperatures from –40
°
C to +85
°
C in 0.5
°
C
increments.
The DS1615 is a powerful data recording device, pro-
viding both a datalog of sampled temperature values
over time and a histogram of temperature. The datalog
function simply samples the temperature at a user
defined sample rate and writes the data to the Tempera-
ture Datalog memory. Up to 2048 datalog samples may
be recorded. Histogram functionality is implemented by
sampling the temperature and then incrementing the
count value in a data bin associated with that tempera-
ture. The DS1615 provides 63 two–byte data bins in
2
°
C increments. The user can program data sampling
for both data logging and for histogram tabulation at
intervals ranging from once per minute to once every
255 minutes.
The DS1615 also supports programmable high and low
temperature alarm trip points that allow the device to
monitor whether the temperature stays within desired
limits. The device can drive an interrupt or status pin if
the temperature falls outside of the programmable lim-
its. The DS1615 can be programmed to begin sampling
data via a pushbutton input or via a command sent over
the serial interface with a host machine.
The DS1615 also provides an optional 64–bit serial
number which is useful for product identification and
tracking.
OVERVIEW
The block diagram in Figure 1 shows the relationship
between the major control and memory sections of the
DS1615. The device has five major data components:
1) 32–byte Real Time Clock and control block, 2)
32–byte User NVRAM with optional 64–bit lasered
serial number, 3) 96 bytes of Alarm event/duration
memory, 5) 128 bytes of histogram RAM, and 6) 2048
bytes of datalog memory. All memory is arranged in a
single linear address space.
