CAT15008, CAT15016
Voltage Supervisor with 8-Kb and 16-Kb
SPI Serial CMOS EEPROM
FEATURES
DESCRIPTION
The CAT15008/16 (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.
Precision Power Supply Voltage Monitor
5V, 3.3V, 3V & 2.5V systems
7 threshold voltage options
Active High or Low Reset
Valid reset guaranteed at VCC = 1V
10MHz SPI compatible
The CAT15008/16 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.
32-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.

PIN DESCRIPTION
DEVICE OPERATION
¯¯¯¯¯¯
RESET/RESET: Reset output is available in two
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.
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.
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.
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.
The CAT15008/16 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.
¯¯
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.

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).
EMBEDDED EEPROM DESCRIPTION
The CAT15008/16 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 CAT15008/16 is accom–
plished by simply providing the READ command and an
address. Writing to the CAT15008/16, 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.
T
AMB
= 25ºC
¯¯
After a high to low transition on the CS input pin, the
CAT15008/16 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.

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

WRITE OPERATIONS
¯¯
The CAT15008/16 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.
take the CS input high after the WREN instruction, as
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 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 CAT15008/16. Care must be taken to

Page Write
Once the WEL bit is set, the user may execute a write
sequence, by sending a WRITE instruction, a 16-bit
address and data as shown in Figure 6. Only 10
significant address bits are used by the CAT15008
and 11 by the CAT15016. The rest are don’t care bits,
as shown in Table 5. Internal programming will start
After sending the first data byte to the CAT15008/16,
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 CAT15008/16 is
automatically returned to the write disable state.

Write Status Register
Write Protection
¯¯¯
The Status Register is written by sending a WRSR
instruction according to timing shown in Figure 8. Only
bits 2, 3 and 7 can be written using the WRSR
command.
The Write Protect (WP) pin can be used to protect the
Block Protect bits BP0 and BP1 against being
inadvertently altered. When WP is low and the WPEN
bit is set to “1”, write operations to the Status Register
¯¯¯
¯¯¯
¯¯
are inhibited. WP going low while CS is still low will
interrupt a write to the status register. If the internal
¯¯¯
write cycle has already been initiated, WP going low
will have no effect on any write operation to the Status
¯¯¯
Register. The WP pin function is blocked when the
¯¯¯
WPEN bit is set to “0”. The WP input timing is shown
in Figure 9.

READ OPERATIONS
Read Status Register
Read from Memory Array
To read the status register, the host simply sends a
RDSR command. After receiving the last bit of the
command, the CAT15008/16 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.
To read from memory, the host sends a READ
instruction followed by a 16-bit address (see Table 5 for
the number of significant address bits).
After receiving the last address bit, the CAT15008/16
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
reaching the highest memory address, the address
counter “rolls over” to the lowest memory address, and
