Description
The CAT1163 is a complete memory and supervisory solution for
microcontroller−based systems. A serial 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

I C bus.
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.
PIN CONFIGURATION
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 5 V, 3.3 V and 3 V
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
200 ms 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 a
debounced input for pushbutton manual reset capability.

STOP Condition
The CAT1163 supports the I C Bus data transmission
A LOW to HIGH transition of SDA when SCL is HIGH
determines the STOP condition. All operations must end
with a STOP condition.
protocol. This Inter−Integrated Circuit Bus protocol 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.
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.
The next three bits (Figure 6) define memory addressing.
For the CAT1163 the three bits define higher order bits.
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.
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 operation depending on the
R/W bit.
I2C Bus Protocol
The features of the I C bus protocol are defined as
2
follows:
1. Data transfer may be initiated only when the bus is
not busy.
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.
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.

responds with an acknowledge after receiving each 8−bit
byte.
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
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 transmission
and waits for a STOP condition.

CAT1163
WRITE OPERATIONS
Page Write
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. 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 receiving another acknowledge from the Slave, the
Master device transmits the data to be written into the
addressed memory location. The CAT1163 acknowledges
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.
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.
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.
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.

Figure 8. Page Write Timing
Acknowledge Polling
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 operation, 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.
WRITE PROTECTION
The Write Protection feature allows the user to protect
against inadvertent memory array programming. 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.

READ OPERATIONS
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
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 the R/W bit set to one), it issues an
acknowledge, then transmits the 8−bit byte requested. The
master device does not send an acknowledge, but will
generate a STOP condition.

memory 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, 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.
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 negative edge is sensed
if RESET is used as a manual reset input.
An internal counter starts a 200 ms 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 200 ms, the complementary reset output will
switch back to the non active state after the 200 ms expired,
regardless for how long the manual reset input is forced
active.
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 controlled
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 data being transmitted from the CAT1163 is outputted
sequentially with data from address N followed by data from
address N+1. The READ operation address counter
increments all of the CAT1163 address bits so that the entire
time−out period, t , the memory will not respond with
