The power supply monitor and reset circuit protect
system controllers during power up/down and against
brownout conditions. Seven reset threshold voltages
support 5V, 3.3V, 3V and 2.5V systems. If power
supply voltages are out of tolerance reset signals
become active, preventing the system microcontroller,
ASIC or peripherals from operating. Reset signals
become inactive typically 240ms after the supply
voltage exceeds the reset threshold level.
DESCRIPTION
The CAT15002/04 (see table below) are memory and
supervisory solutions for microcontroller based
systems. A CMOS serial EEPROM memory and a
system power supervisor with brown-out protection
are integrated together. Memory interface is via SPI
bus serial interface.
The CAT15002/04 provides a precision V
CC
sense
circuit with two reset output options: CMOS active low
output or CMOS active high. The RESET output is
active whenever V
CC
is below the reset threshold or
falls below the reset threshold voltage.

Notes:
(1) Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions outside of those listed in the operational sections of this
specification is not implied. Exposure to any absolute maximum rating for extended periods may affect device performance and reliability.
(2) The DC input voltage on any pin should not be lower than -0.5V or higher than V
CC
+ 0.5V. During transitions, the voltage on any pin may
undershoot to no less than -1.5V or overshoot to no more than V
CC
+ 1.5V, for periods of less than 20ns.
(3) These parameters are tested initially and after a design or process change that affects the parameter according to appropriate AEC-Q100
and JEDEC test methods.

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 CAT15002/04.
¯¯
CS:
The chip select input pin is used to enable/disable
¯¯
the CAT15002/04. 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 CAT15002/04 must be preceded by a high to low
transition and concluded with a low to high transition of
¯¯
the CS input.
¯¯¯:
The write protect input pin will allow all write
WP
operations to the device when held high. When ¯¯¯
WP
pin is tied low all write operations are inhibited.
DEVICE OPERATION
The CAT15002/04 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 (t
PURST
) after the
power supply voltage has risen above the threshold.
Reset output timing is shown in Figure 1.
The CAT15002/04 devices protect µPs against brown-out
failure. Short duration V
CC
transients of 4µsec or less and
100mV amplitude typically do not generate a Reset pulse.
