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 outputs. During power-up, the RESET outputs  
remain active until VCC reaches the VTH threshold and  
will continue driving the outputs for approximately  
200ms (tPURST) after reaching VTH. After the tPURST

Watchdog Timer  
SDA: SERIAL DATA ADDRESS  
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 SDA input. If the microcontroller  
does not toggle the SDA 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.  
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.

CAT1163  
STOP Condition  
FUNCTIONAL DESCRIPTION  
A LOW to HIGH transition of SDA when SCL is HIGH  
determines the STOP condition. All operations must  
end with a STOP condition.  
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.  
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.  
I2C BUS PROTOCOL  
The features of the I2C bus protocol are defined as  
follows:  
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.  
(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.  
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  
¯¯  
operation depending on the R/W bit.  
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 ope–  
rations 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. For all devices,  
N=E=2047. The counter will wrap around to Zero and  
continue to clock out valid data for the 16K devices.  
After the CAT1163 receives its slave address  
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.  
¯¯  
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.

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,

as a manual reset input.

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  
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 memory  
controlled time-out period, tPURST, the memory will not  
respond with an acknowledge for any access as long as  
the manual reset input is active.
