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

seconds, the watchdog timer times out.

RESET outputs. During power-up, the RESET outputs

remain active until V_CCreaches the V_THthreshold and

will continue driving the outputs for approximately

200ms (t_PURST) after reaching V_TH. After the t_PURST

timeout interval, the device will cease to drive the

reset outputs. At this point the reset outputs will be

pulled up or down by their respective pull up/down

resistors. During power-down, the RESET outputs will

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.

be active when V_CCfalls below V_TH. The RESET

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

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

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.

initiate a reset timeout after detecting a high to low

transition.

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.

SCL: SERIAL CLOCK

Serial clock input.

DEVICE OPERATION

Reset Controller Description

The CAT1163 precision RESET controller ensures

correct system operation during brownout and power

up/down conditions. It is configured with open drain

As long as the reset signal is asserted, the Watchdog

Timer will not count and will stay cleared.
