(RESET CAT1021/23 Only)  
Pin  
Name  
RESET/RESET: RESET OUTPUT  
Function  
¯¯¯¯¯¯  
These are open drain pins and RESET can be used  
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  
¯¯¯¯¯¯  
resistor.

Power Supply  
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.

OPERATING TEMPERATURE RANGE  
¯¯¯  
MR: MANUAL RESET INPUT  
Industrial  
-40ºC to 85ºC  
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.  
Extended -40ºC to 125ºC  
WP (CAT1021 Only): WRITE PROTECT INPUT  
When WP input is tied to VSS or left unconnected write  
operations to the entire array are allowed. When tied  
to VCC, the entire array is protected. This input has an  
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.
