PIN DESCRIPTION
RESET/RESET
(RESET CAT1021/23 Only)
These are open drain pins and RESET
as a manual reset trigger input. By forcing a reset
condition on the pin the device will initiate and
maintain a reset condition. The RESET pin must be
connected through a pull-down resistor, and the
¯¯¯¯¯¯ pin must be connected through a pull-up
RESET
resistor.
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.
SCL: SERIAL CLOCK
Serial clock input.
¯¯¯ : MANUAL RESET INPUT
Manual Reset input is a debounced input that can be
connected to an external source for Manual Reset.
Pulling the MR input low will generate a Reset
condition. Reset outputs are active while MR input is
low and for the reset timeout period after MR returns
to high. The input has an internal pull up resistor.
WP (CAT1021 Only): WRITE PROTECT INPUT
When WP input is tied to V
operations to the entire array are allowed. When tied
to V
internal pull down resistor.
WDI (CAT1023 Only): WATCHDOG TIMER INTERRUPT
Watchdog Timer Interrupt Input is used to reset the
watchdog timer. If a transition from high to low or low
to high does not occur every 1.6 seconds, the RESET
outputs will be driven active.
