MR:  
MANUAL RESET INPUT  
PIN DESCRIPTION  
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.  
RESET/RESET: RESET OUTPUTS  
(RESET CAT1021/23 Only)  
These are open drain pins and RESET can be used as a  
manual reset trigger input. By forcing a reset condition on  
thepinthedevicewillinitiateandmaintainaresetcondition.  
The RESET pin must be connected through a pull-down  
resistor, and the RESET pin must be connected through a  
pull-up resistor.  
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.  
SDA: SERIAL DATA ADDRESS  
Thebidirectionalserialdata/addresspinisusedtotransfer  
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.  
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.  
SCL: SERIAL CLOCK  
Serial clock input.
