after reaching V_TH. After the t_PURSTtimeout interval, the

device will cease to drive the reset outputs. At this point the

resetoutputswillbepulledupordownbytheirrespectivepull

up/down resistors. During power-down, the RESET outputs

will be active when V_CCfalls below V_TH. The RESET outputs

will be valid so long as V_CCis >1.0V (V_RVALID).

If the pin is tied to V_CCthe entire memory array

becomes Write Protected (READ only). When the pin

is tied to GND or left floating normal read/write

operations are allowed to the device.

SCL: SERIAL CLOCK

If there is no transition on the WDI for more than 1.6

seconds, the watchdog timer times out.

The RESET pins are I/Os; therefore, the CAT24CXXX can

act as a signal conditioning circuit for an externally applied

reset.Theinputsareedgetriggered;thatis,theRESETinput

in the 24CXXX will initiate a reset timeout after detecting a

lowtohightransitionandtheRESETinputintheCAT24CXXX

will initiate a reset timeout after detecting a high to low

transition.

RESET/RESET: RESET I/O

These are open drain pins and can be used as reset

trigger inputs. By forcing a reset condition on the pins

the device will initiate and maintain a reset condition

for approximately 200ms. The RESET pin must be

connected through a pull-down resistor, and the

RESET pin must be connected through a pull-up

resistor.

Watchdog Timer

TheWatchdogTimerprovidesanindependentprotectionfor

microcontrollers. During a system failure, the CAT24CXXX

will respond with a reset signal after a time-out interval of

1.63 seconds for a lack of activity. The CAT24CXX1 is

designedwiththeWatchdogTimerfeatureontheSDAinput.

For the CAT24CXX1, if the microcontroller does not toggle

the SDA input pin within 1.6 sectonds, the Watchdog Timer

times out. This will generate a reset condition on reset

outputs. The Watchdog Timer is cleared by any transition on

WDI.

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.

DEVICE OPERATION

Reset Controller Description

As long as the reset signal is asserted, the Watchdog Timer

will not count and will stay cleared. The CAT24CXX2 does

not have a Watchdog.

The CAT24CXXX precision RESET controller ensures

correct system operation during brownout and power

up/down conditions. It is configured with open drain

RESET outputs. During power-up, the RESET outputs
