PIN DESCRIPTIONS
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.
See Table 1 for the 388-pin balls and the Packages section for the chip illustrations.

DIN[31:0] (Input)
DIN[31:0] are synchronous port data input pins. Data is
loaded into the MUAA RCP right aligned, least significant
word first.
/DINE (Input)
DIN is sampled by the rising edge of CLK when /DINE is
asserted. Refer to Table 1 for slave connections.
OP[3:0] (Input)
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.
DINREADY (Output)
When DINREADY is HIGH, the synchronous port
accepted the current operation. This is affected by the
priority set for the DIN port and the processor port. Note,
DINREADY may be LOW for up to 800 CLK periods
after /RESET is taken HIGH. The JTAG interface is able
to set DINREADY to HIGH-Z. Active HIGH.
DOUT[31:0] (3-State Output)
DOUT[31:0] is the synchronous port data output. Data is
read out right aligned, least significant word first. The
address index (bits 25–0), SWEX flag (bit 26), PWEX flag
(bit 27), LQUEUE flag (bit 28), AQUEUE flag (bit 29),
Sync Port Match flag (bit 30), and Full flag (bit 31) may
also be read from this port before or after operation data
depending on configuration.
