V
bat
–
Battery input for standard lithium cell or other
energy source. All functions of the DS1615 with the
exception of the serial interface circuitry are powered by
V
bat
when V
CC
< V
bat
. All functions are powered by V
CC
when V
CC
> V
bat
.
GND –
Ground
COMSEL (Communication Select Input)
–
This pin
determines whether serial communication is asynchro-
nous or synchronous. When pulled high to V
CC
, com-
munication is synchronous and will take place via the
SCLK, I/O, and RST pins. When COMSEL is tied to
ground, asynchronous communication utilizing the TX
and RX pins is selected. If this pin is floated, the DS1615
will operate in the asynchronous communications mode
since the COMSEL pin has a weak internal pull–down
resistor.
Tx (Transmit Output) –
Transmit output of the asynch-
ronous serial interface. Tx is tri–stated whenever V
CC
<
V
bat
.
Rx (Receive Input) –
Receive input of the asynchro-
nous serial interface.
SCLK (3–Wire Serial Clock Input)
– The SCLK pin is
the serial clock input for the 3–wire synchronous com-
munications channel.
I/O (3–Wire Input/Output)
– The I/O pin is the data
Input/Output signal for the 3–wire synchronous commu-
nications channel.
RST (3–Wire Reset Input)
–
The RST pin is the com-
munications reset pin for the 3–wire synchronous com-
munications channel.
INT (Interrupt Output) –
The INT pin is an open drain
active low output that can be used as an interrupt input
to a microprocessor. The INT output remains low as
long as the status bit causing the interrupt is present and
the corresponding interrupt–enable bit is set.
INSPEC (Open Drain In–Specification Output)
–
This
pin, in conjunction with the OUTSPEC pin, is used to
signal the status of the operation and data of the
DS1615.
OUTSPEC (Open Drain Out–of–Specification Out-
put)
– This pin, in conjunction with the INSPEC pin, is
used to signal the status of the operation and data of the
DS1615.
ST (Start/Status Button Input)
– The ST pin provides
two functions. First, when enabled as the datalog start
source (SE bit in Control register is a logic 1), the ST pin
is used to instruct the DS1615 to begin recording tem-
perature data based on the programmed start delay and
data sample rate. The ST pin must be held low for at
least 0.5 seconds for a datalog mission to begin.
Secondly, the ST pin can be used to poll the status of the
recorded data. After datalogging has begun, the ST pin
instructs the DS1615 to report the status of the recorded
data via the INSPEC and OUTSPEC pins.
X1, X2 –
Connections for a standard 32.768 kHz quartz
crystal, Daiwa part number DT–26S or equivalent. For
greatest accuracy, the DS1615 must be used with a
crystal that has a specified load capacitance of 6 pF.
There is no need for external capacitors or resistors.
Note: X1 and X2 are very high impedance nodes. It is
recommended that they and the crystal be guard–
ringed with ground and that high frequency signals be
kept away from the crystal area. For more information
on crystal selection and crystal layout considerations,
please consult Application Note 58, Crystal Consider-
ations with Dallas Real Time Clocks.
NC (No Connect) –
This pin should be left uncon-
nected.
MEMORY
The memory map in Figure 2a shows the general orga-
nization of the DS1615. As can be seen in the figure, the
device is segmented into 32 byte pages. Page 0 con-
tains the Real Time Clock and Control registers (see
Figure 2b for more detail). The User NV RAM resides in
page 1. Pages 17 to 19 are assigned to storing the
alarm time stamps and durations. The temperature his-
togram bins begin at page 64 and use up four pages.
The temperature logging memory covers pages 128 to
191. Memory pages 2 to 16, 20 to 63, 68 to 127, and 192
and up are reserved for future extensions.
The end user can write only to the Real Time Clock and
Control registers and the User NV RAM. The rest of the
memory map is read–only from the end users perspec-
tive.
