Description
ODT Configuration Select â Set the default ODT state for various combinations of input groups during
power-up and reset, when MZT[1:0] = 01 or 10. Must be tied High or Low.
PZT[1:0] = 00: enables ODT on write data only.
PZT[1:0] = 01: enables ODT on write data and input clocks.
PZT[1:0] = 10: enables ODT on write data, address, and control.
PZT[1:0] = 11: enables ODT on write data, input clocks, address, and control.
Note: The ODT state for each input group can be changed at any time via the Configuration Registers.
Core Power Supply
I/O Power Supply
Input Reference Voltage â Input buffer reference voltage.
Ground
JTAG Clock â Weakly pulled Low internally.
JTAG Mode Select â Weakly pulled High internally.
JTAG Data Input â Weakly pulled High internally.
JTAG Data Output
Must Connect High â May be tied to VDDQ directly or via a 1kï resistor.
Must Connect Low â May be tied to VSS directly or via a 1kï resistor.
No Connect â There is no internal chip connection to these pins. They may be left unconnected, or tied/
driven High or Low.
Not Used Input â There is an internal chip connection to these input pins, but they are unused by the
device. They are pulled Low internally. They may be left unconnected or tied/driven Low. They should not be
tied/driven High.
Not Used Input/Output â There is an internal chip connection to these I/O pins, but they are unused by the
device. The drivers are tri-stated internally. They are pulled Low internally. They may be left unconnected or
tied/driven Low. They should not be tied/driven High.
