Terminal Functions (Continued) SIGNAL DESCRIPTION IPD/ IPU‡ TYPE† NAME DESCRIPTION IPD/ IPU‡ TYPE† DM640 DM641 J2 J2 I/O/Z — K1 K1 I/O/Z — Pull down via a 10-kΩ resistor K3 K3 I/O/Z — Pull down via a 10 kΩ resistor R4 R4 I IPU R25 R25 O/Z IPU R26 R26 O/Z IPU Reserved (leave unconnected do not connect to power or ground) T4 T4 O IPD Reserved (leave unconnected, do not connect to power or ground) T22 T22 O/Z IPU T23 T23 O/Z IPU V4 V4 I/O/Z — Pull down via a 10-kΩ resistor W7 W7 A — W23 W23 I/O/Z IPU Y23 Y23 I/O/Z IPU Y24 Y24 I/O/Z IPU Y25 Y25 I/O/Z IPU Y26 Y26 I/O/Z IPU AA3 AA3 A — AA23 AA23 I/O/Z IPU AA24 AA24 I/O/Z IPU RSV AA25 AA25 I/O/Z IPU RSV AA26 AA26 I/O/Z IPU AB3 AB3 I — AB11 AB11 I/O/Z IPD AB12 AB12 I/O/Z IPD AB15 AB15 I/O/Z IPD Reserved (leave unconnected do not connect to power or ground) AB23 AB23 I/O/Z IPU Reserved (leave unconnected, do not connect to power or ground) AB24 AB24 I/O/Z IPU AB25 AB25 I/O/Z IPU AC4 AC4 O/Z — AC11 AC11 I/O/Z IPD AC15 AC15 I/O/Z IPD AC19 AC19 I/O/Z IPU AC20 AC20 I/O/Z IPU AC21 AC21 I/O/Z IPU AC25 AC25 I/O/Z IPU AC26 AC26 I/O/Z IPU AD3 AD3 O/Z — AD9 AD9 I/O/Z IPD AD11 AD11 I/O/Z IPD AD19 AD19 I/O/Z IPU † I = Input, O = Output, Z = High impedance, S = Supply voltage, GND = Ground ‡ IPD = Internal pulldown, IPU = Internal pullup. (These IPD/IPU signal pins feature a 30-kΩ IPD or IPU resistor. To pull up a signal to the opposite supply rail, a 1-kΩ resistor should be used.) |
