Note: Signal names that start with a slash (“/”) are active LOW. All signals are 3.3 Volt CMOS level. All input
and bi-directional pins are 5-Volt tolerant, except for CLK. Never leave inputs floating except where
indicated. The CAM architecture draws large currents during search operations, mandating the use of good
layout and bypassing techniques. Refer to the Electrical Characteristics section for more information.

',1>@ ,QSXW
DIN[31:0] are synchronous port data input pins. Data is
loaded into the MUAA RCP right aligned, least significant
word first.
',1( ,QSXW
DIN is sampled by the rising edge of CLK when /DINE is
asserted.
23>@ ,QSXW
OP[3:0] is a synchronous port operation to be performed on
the data applied to the DIN pins. OP is sampled by the rising
edge of CLK when /DINE is asserted. When loading the
CAM/RAM words to DIN, OP is set to LOAD except for the
last word. OP for the last word is set to the desired operation.
