Supervisory Circuits with I2C Serial CMOS EEPROM,
Precision Reset Controller and Watchdog Timer (16K)
EEPROM memory (16K) with hardware memory write
protection, a system power supervisor with brown out
protection and a watchdog timer are integrated
together in low power CMOS technology. Memory
interface is via an I2C bus.
FEATURES
Watchdog timer input (WDI)
400kHz I2C bus compatible
2.7V to 6.0V operation
The 1.6-second watchdog circuit returns a system to a
known good state if a software or hardware glitch
halts or “hangs” the system. The CAT1163 watchdog
monitors the WDI input pin.
Low power CMOS technology
16-Byte page write buffer
Built-in inadvertent write protection

VCC lock out
The power supply monitor and reset circuit protects
memory and system controllers during power up/down
and against brownout conditions. Five reset threshold
voltages support 5V, 3.3V and 3V 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 200ms after the supply
voltage exceeds the reset threshold level. With both
active high and low reset signals, interface to
microcontrollers and other ICs is simple. In addition, a
reset pin can be used as debounced input for push-
button manual reset capability.

RESET/RESET: RESET I/O
The RESET pins are I/Os; therefore, the CAT1163
can act as a signal conditioning circuit for an
externally applied manual reset. The inputs are edge
triggered; that is, the RESET input in the CAT1163 will
initiate a reset timeout after detecting a low to high

SDA: SERIAL DATA ADDRESS
The bidirectional serial data/address pin is used to
transfer all data into and out of the device. The SDA
pin is an open drain output and can be wire-ORed
with other open drain or open collector outputs.
Watchdog Timer
The Watchdog Timer provides an independent
protection for microcontrollers. During a system
failure, the CAT1163 will respond with a reset signal
after a time-out interval of 1.6 seconds for a lack of
activity. The CAT1163 is designed with the Watchdog
Timer feature on the WDI input. If the microcontroller
does not toggle the WDI input pin within 1.6 seconds,
the Watchdog Timer times out. This will generate a
reset condition on reset outputs. The Watchdog Timer
is cleared by any transition on WDI.

CAT1163
FUNCTIONAL DESCRIPTION
The CAT1163 supports the I2C Bus data transmis–
sion protocol. This Inter-Integrated Circuit Bus proto–
col defines any device that sends data to the bus to
be a transmitter and any device receiving data to be a
receiver. The transfer is controlled by the Master
device which generates the serial clock and all
START and STOP conditions for bus access. Both the
Master device and Slave device can operate as either
transmitter or receiver, but the Master device controls
which mode is activated.
STOP Condition
A LOW to HIGH transition of SDA when SCL is HIGH
determines the STOP condition. All operations must
end with a STOP condition.
Device Addressing
The Master begins a transmission by sending a
START condition. The Master sends the address of
the particular slave device it is requesting. The four
most significant bits of the 8-bit slave address are
fixed as 1010.
I2C Bus Protocol
The features of the I2C bus protocol are defined as
follows:
The next three bits (Figure 6) define memory
addressing. For the CAT1163 the three bits define
higher order bits.
(1) Data transfer may be initiated only when the bus
is not busy.
The last bit of the slave address specifies whether a
Read or Write operation is to be performed. When this
bit is set to 1, a Read operation is selected, and when
set to 0, a Write operation is selected.
(2) During a data transfer, the data line must remain
stable whenever the clock line is high. Any
changes in the data line while the clock line is
high will be interpreted as a START or STOP
condition.
After the Master sends a START condition and the
slave address byte, the CAT1163 monitors the bus
and responds with an acknowledge (on the SDA line)
when its address matches the transmitted slave
address. The CAT1163 then performs a Read or Write
START Condition
The START Condition precedes all commands to the
device, and is defined as a HIGH to LOW transition of
SDA when SCL is HIGH. The CAT1163 monitors the
SDA and SCL lines and will not respond until this
condition is met.

CAT1163
Acknowledge
receiving another acknowledge from the Slave, the
Master device transmits the data to be written into the
addressed memory location. The CAT1163 acknow–
ledges once more and the Master generates the STOP
condition. At this time, the device begins an internal
programming cycle to non-volatile memory. While the
cycle is in progress, the device will not respond to any
request from the Master device.
After a successful data transfer, each receiving
device is required to generate an acknowledge. The
acknowledging device pulls down the SDA line
during the ninth clock cycle, signaling that it received
the 8 bits of data.
The CAT1163 responds with an acknowledge after
receiving a START condition and its slave address.
If the device has been selected along with a write
operation, it responds with an acknowledge after
receiving each 8-bit byte.
Page Write
The CAT1163 writes up to 16 bytes of data in a single
write cycle, using the Page Write operation. The page
write operation is initiated in the same manner as the
byte write operation, however instead of terminating
after the initial byte is transmitted, the Master is allowed
to send up to 15 additional bytes. After each byte has
been transmitted, the CAT1163 will respond with an
acknowledge and internally increment the lower order
address bits by one. The high order bits remain
unchanged.
When the CAT1163 begins a READ mode it
transmits 8 bits of data, releases the SDA line and
monitors the line for an acknowledge. Once it
receives this acknowledge, the CAT1163 will
continue to transmit data. If no acknowledge is sent
by the Master, the device terminates data transmis-
sion and waits for a STOP condition.
If the Master transmits more than 16 bytes before
sending the STOP condition, the address counter
‘wraps around,’ and previously transmitted data will be
overwritten.
WRITE OPERATIONS
Byte Write
In the Byte Write mode, the Master device sends the
START condition and the slave address information
¯¯
(with the R/W bit set to zero) to the Slave device.
When all 16 bytes are received, and the STOP
condition has been sent by the Master, the internal
programming cycle begins. At this point, all received
data is written to the CAT1163 in a single write cycle.
After the Slave generates an acknowledge, the
Master sends a 8-bit address that is to be written
into the address pointers of the CAT1163. After

CAT1163
Acknowledge Polling
READ OPERATIONS
Disabling of the inputs can be used to take
advantage of the typical write cycle time. Once the
stop condition is issued to indicate the end of the
host’s write opration, the CAT1163 initiates the
internal write cycle. ACK polling can be initiated
immediately. This involves issuing the start condition
followed by the slave address for a write operation. If
the CAT1163 is still busy with the write operation, no
ACK will be returned. If a write operation has
completed, an ACK will be returned and the host can
then proceed with the next read or write operation.
The READ operation for the CAT1163 is initiated in the
same manner as the write operation with one exception,
¯¯
that R/W bit is set to one. Three different READ
operations are possible: Immediate/Current Address
READ, Selective/Random READ and Sequential READ.
Immediate/Current Address Read
The CAT1163’s address counter contains the address
of the last byte accessed, incremented by one. In other
words, if the last READ or WRITE access was to
address N, the READ immediately following would
access data from address N + 1. If N = E (where = 2047
for the CAT1163) then the counter will ’wrap around’ to
address 0 and continue to clock out data. After the
CAT1163 receives its slave address information (with
WRITE PROTECTION
The Write Protection feature allows the user to
protect against inadvertent memory array program-
ming. If the WP pin is tied to VCC, the entire memory
array is protected and becomes read only. The
CAT1163 will accept both slave and byte addresses,
but the memory location accessed is protected from
programming by the device’s failure to send an
acknowledge after the first byte of data is received.

transmits the 8-bit byte requested. The master device
does not send an acknowledge, but will generate a
STOP condition.

CAT1163
Selective/Random Read
array can be read during one operation. If more than E
(where E=2047 for the CAT1163) bytes are read out,
the counter will ‘wrap around’ and continue to clock out
data bytes.
Selective/Random READ operations allow the
Master device to select at random any memory
location for a READ operation. The Master device
first performs a ‘dummy’ write operation by sending
the START condition, slave address and byte
addresses of the location it wishes to read. After the
CAT1163 acknowledges, the Master device sends
the START condition and the slave address again,
Manual Reset Operation
¯¯¯¯¯¯
The CAT116x RESET or RESET pin can also be used
as a manual reset input.
Only the “active” edge of the manual reset input is
internally sensed. The positive edge is sensed if
RESET is used as a manual reset input and the
¯¯
this time with the R/W bit set to one. The CAT1163
then responds with its acknowledge and sends the
8-bit byte requested. The master device does not
send an acknowledge but will generate a STOP
condition.
¯¯¯¯¯¯
negative edge is sensed if RESET is used as a manual
reset input.
An internal counter starts a 200ms count. During this
time, the complementary reset output will be kept in the
active state. If the manual reset input is forced active for
more than 200ms, the complementary reset output will
switch back to the non active state after the 200ms
expired, regardless for how long the manual reset input
is forced active.
Sequential Read
The Sequential READ operation can be initiated by
either the Immediate Address READ or Selective
READ operations. After the CAT1163 sends the
inital 8-bit byte requested, the Master will responds
with an acknowledge which tells the device it
requires more data. The CAT1163 will continue to
output an 8-bit byte for each acknowledge, thus
sending the STOP condition.
The embedded EEPROM is disabled as long as a reset
condition is maintained on any RESET pin. If the
¯¯¯¯¯¯
external forced RESET/RESET is longer than internal
