DATA OUTPUT
Following the eight CLK cycles that input read mode
protocol, 32 bits of data will be output from the selected
counter on the next 32 CLK cycles. The first data bit to
be transmitted from the selected 32–bit counter occurs
on the falling edge after the last bit of protocol is written.
When transmitting data from the selected 32–bit count-
er, RST must remain at high level as a transition to low
level will terminate data transfer. Data is driven out the
DQ pin as long as CLK is low. When CLK is high the DQ
pin is tristated.
OSCILLATOR OUTPUT
Pin 6 of the DS1603 module is a 1 Hz output signal. This
signal is present only when V
CC
is applied and greater
than the internal power supply. However, the output is
guaranteed to meet TTL requirement only while V
CC
is
within normal limits. This output can be used as a one
second interrupt or time tick needed in some applica-
tions.
INTERNAL POWER
The internal battery of the DS1603 module provides 35
mAh and will run the elapsed time counter for over 10
years in the absence of power.
