PIN DESCRIPTION
RESET/RESET
: Reset output is available in two
versions: CMOS Active Low (CAT150xx9) and CMOS
Active High (CAT150xx1). Both versions are push-pull
outputs for high efficiency.
SI: The serial data input pin accepts op-codes,
addresses and data. In SPI modes (0,0) and (1,1)
input data is latched on the rising edge of the SCK
clock input.
SO: The serial data output pin is used to transfer data
out of the device. In SPI modes (0,0) and (1,1) data is
shifted out on the falling edge of the SCK clock.
SCK: The serial clock input pin accepts the clock
provided by the host and used for synchronizing
communication between host and CAT15008/16.
CS
: The chip select input pin is used to enable/disable
the CAT15008/16. When CS
is high, the SO output is
tri-stated (high impedance) and the device is in
Standby Mode (unless an internal write operation is in
progress). Every communication session between host
and CAT15008/16 must be preceded by a high to low
transition and concluded with a low to high transition of
the CS
input.
WP
: The write protect input pin will allow all write
operations to the device when held high. When WP
pin is tied low and the WPEN bit in the Status
Register (refer to Status Register description, later in
this Data Sheet) is set to “1”, writing to the Status
Register is disabled.
DEVICE OPERATION
The CAT15008/16 products combine the accurate
voltage monitoring capabilities of a standalone voltage
supervisor with the high quality and reliability of
standard EEPROMs from Catalyst Semiconductor.
RESET CONTROLLER DESCRIPTION
The reset signal is asserted LOW for the CAT150xx9
and HIGH for the CAT150xx1 when the power supply
voltage falls below the threshold trip voltage and
remains asserted for at least 140ms (tPURST) after the
power supply voltage has risen above the threshold.
Reset output timing is shown in Figure 1.
The CAT15008/16 devices protect Ps against brown-out
failure. Short duration VCC transients of 4sec or less and
100mV amplitude typically do not generate a Reset pulse.
