LANCAM B Family  
Pin Descriptions  
/MI (Match Input, Input, TTL)  
/FI (Full Input, Input, TTL)  
The /MI input prioritizes devices in vertically cascaded  
systems. It is connected to the /MF output of the previous  
device in the daisy chain. The /MI pin on the first device in  
the chain must be tied HIGH.  
The /FI input generates a CAM-Memory-System-Full  
indication in vertically cascaded systems. It is connected  
to the /FF output of the previous device in the daisy chain.  
The /FI pin on the first device in a chain must be tied  
LOW.  
/MA (Device Match Flag, Output, TTL)  
/RESET (Reset, Input, TTL)  
The /MA output is LOW when one or more valid matches  
occur during the current or the last previous compare  
cycle. The /MA output is not qualified by /EC or /MI, and  
reflects the match flag from that specific device’s Status  
register. /MA is reset when the active register set is  
changed.  
/RESET must be driven LOW to place the device in a  
known state before operation, which resets the device to  
the conditions shown in Table 3 on page 11. The /RESET  
pin should be driven by TTL levels, not directly by an RC  
timeout. /E must be kept HIGH during /RESET.  
/MM (Device Multiple Match Flag, Output, TTL)  
The /MM output is LOW when more than one valid match  
occurs during the current or the last previous compare  
cycle. The /MM output is not qualified by /EC or /MI, and  
reflects the multiple match flag from that specific device’s  
Status register. /MM is reset when the active register set is  
changed.  
TEST1, TEST2 (Test, Input, TTL)  
These pins enable MUSIC production test modes that are  
not usable in an application. They should be connected to  
ground, either directly or through a pull-down resistor, or  
they may be left unconnected. These pins may not be  
implemented on all versions of these products.  
VCC, GND (Positive Power Supply, Ground)  
/FF (Full Flag, Output, TTL)  
These pins are the power supply connections to the  
LANCAM. VCC must meet the voltage supply  
requirements in the Operating Conditions section relative  
to the GND pins, which are at 0 volts (system reference  
potential), for correct operation of the device. All the  
ground and power pins must be connected to their  
respective planes with adequate bulk and high frequency  
bypassing capacitors in close proximity to the device.  
If enabled in the Control register, the /FF output goes  
LOW when no empty memory locations exist within the  
device (and in the daisy chain above the device as  
indicated by the /FI pin). The System Full flag is the /FF  
pin of the last device in the daisy chain, and the Next Free  
address resides in the device with /FI LOW and /FF  
HIGH. If disabled in the Control register, the /FF output  
only depends on the /FI input (/FF = /FI).
