No Function/Parity Data I/Os: On the x32 version, these pins are No Function (NF). On the x18
version, byte “a” parity is DQPa; byte “b” parity is DQPb. On the x36 version, byte “a” parity
is DQPa; byte “b” parity is DQPb; byte “c” parity is DQPc; byte “d” parity is DQPd.
Power Supply: See DC Electrical Characteristics and Operating Conditions for range.
Isolated Output Buffer Supply: See DC Electrical Characteristics and Operating Conditions for
range.
Ground: GND.
Do Not Use: These pins are internally connected to the die. They may be left floating or
connected to ground to improve package heat dissipation.
No Connect: These pins are not internally connected to the die. They may be left floating,
driven by signals, or connected to ground to improve package heat dissipation.
No Function: These pins are internally connected to the die and have the capacitance of an
input pin. They may be left floating, driven by signals, or connected to ground to improve
package heat dissipation.
