Serial CMOS EEPROM
FEATURES
DESCRIPTION
„ Precision Power Supply Voltage Monitor
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.
ƒ 5V, 3.3V, 3V & 2.5V systems
ƒ 7 threshold voltage options
„ Active High or Low Reset
ƒ Valid reset guaranteed at VCC = 1V
„ 10MHz SPI compatible
The CAT15002/04 provides a precision VCC sense
circuit with two reset output options: CMOS active low
output or CMOS active high. The RESET output is
active whenever VCC is below the reset threshold or
falls below the reset threshold voltage.
„ 16-byte page write buffer
„ Low power CMOS technology
„ 1,000,000 Program/Erase cycles
„ 100 year data retention
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.

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 VCC + 0.5V. During transitions, the voltage on any pin may
undershoot to no less than -1.5V or overshoot to no more than VCC + 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

PIN DESCRIPTION
DEVICE OPERATION
¯¯¯¯¯¯: Reset output is available in two
RESET/RESET
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.
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 (tPURST) after the
power supply voltage has risen above the threshold.
Reset output timing is shown in Figure 1.
SCK: The serial clock input pin accepts the clock
provided by the host and used for synchronizing
communication between host and CAT15002/04.
The CAT15002/04 devices protect µPs against brown-out
failure. Short duration VCC transients of 4µsec or less and
100mV amplitude typically do not generate a Reset pulse.

EMBEDDED EEPROM DESCRIPTION
TRANSIENT DURATION [µs]
Figure 2 shows the maximum pulse duration of
negative-going VCC transients that do not cause a reset
condition. As the amplitude of the transient goes further
below the threshold (increasing VTH - VCC), the
maximum pulse duration decreases. In this test, the
VCC starts from an initial voltage of 0.5V above the
threshold and drops below it by the amplitude of the
overdrive voltage (VTH - VCC).
The CAT15002/04 devices support the Serial Peripheral
Interface (SPI) bus protocol, modes (0,0) and (1,1). The
device contains an 8-bit instruction register. The
instruction set and associated op-codes are listed in
Table 1.
Reading data stored in the CAT15002/04 is accom–
plished by simply providing the READ command and an
address. Writing to the CAT15002/04, in addition to a
WRITE command, address and data, also requires
enabling the device for writing by first setting certain bits
in a Status Register, as will be explained later.

¯¯ input pin, the
After a high to low transition on the CS
CAT15002/04 will accept any one of the six instruction
op-codes listed in Table 1 and will ignore all other
possible 8-bit combinations. The communication
protocol follows the timing from Figure 3.

STATUS REGISTER
The Status Register, as shown in Table 2, contains a
number of status and control bits.
The ¯¯¯¯
RDY (Ready) bit indicates whether the device is
busy with a write operation. This bit is automatically
set to 1 during an internal write cycle, and reset to 0
when the device is ready to accept commands. For
the host, this bit is read only.
The WEL (Write Enable Latch) bit is set/reset by the
WREN/WRDI commands. When set to 1, the device is
in a Write Enable state and when set to 0, the device
is in a Write Disable state.
The BP0 and BP1 (Block Protect) bits determine
which blocks are currently write protected. They are
set by the user with the WRSR command and are
non-volatile. The user is allowed to protect a quarter,
one half or the entire memory, by setting these bits
according to Table 3. The protected blocks then
become read-only.

otherwise the Write Enable Latch will not be properly
set. WREN timing is illustrated in Figure 4. The WREN
instruction must be sent prior any WRITE or WRSR
instruction.
The CAT15002/04 device powers up into a write disable
state. The device contains a Write Enable Latch (WEL)
which must be set before attempting to write to the
memory array or to the status register. In addition, the
address of the memory location(s) to be written must be
outside the protected area, as defined by BP0 and BP1
bits from the status register.
The internal write enable latch is reset by sending the
WRDI instruction as shown in Figure 5. Disabling write
operations by resetting the WEL bit, will protect the
device against inadvertent writes.
Write Enable and Write Disable
The internal Write Enable Latch and the corresponding
Status Register WEL bit are set by sending the WREN
instruction to the CAT15002/04. Care must be taken to

Once the WEL bit is set, the user may execute a write

Page Write
After sending the first data byte to the CAT15002/04,
the host may continue sending data, up to a total of 32
bytes, according to timing shown in Figure 7. After
each data byte, the lower order address bits are
automatically incremented, while the higher order
address bits (page address) remain unchanged. If
during this process the end of page is exceeded, then
loading will “roll over” to the first byte in the page, thus
possibly overwriting previoualy loaded data. Following
completion of the write cycle, the CAT15002/04 is
automatically returned to the write disable state.

Read from Memory Array
To read from memory, the host sends a READ
instruction followed by an 8-bit address (for the
CAT15008, bit 3 of the Read instruction opcode
contains address bit A8).
Read Status Register
To read the status register, the host simply sends a
RDSR command. After receiving the last bit of the
command, the CAT15002/04 will shift out the contents
of the status register on the SO pin (Figure 11). The
status register may be read at any time, including
during an internal write cycle.
After receiving the last address bit, the CAT15002/04
will respond by shifting out data on the SO pin (as
shown in Figure 10). Sequentially stored data can be
read out by simply continuing to run the clock. The
internal address pointer is automatically incremented
to the next higher address as data is shifted out. After
