6 / 59 page AS4C64M8D2 Confidential 6 Rev. 1.0 Feb. /2014 DQS, DQS# Input / Output Bidirectional Data Strobe: Output with read data, input with write data for source synchronous operation. Edge- aligned with read data, center-aligned with write data. DQS# is only used when differential data strobe mode is enabled via the LOAD MODE command. DM Input Data Input Mask: DM is an input mask signal for write data. Input data is masked when DM is sampled HIGH along with that input data during a WRITE access. DQ0 – DQ7 Input / Output Data I/O: Bi-directional data bus. ODT Input On Die Termination: ODT enables internal termination resistance. It is applied to each DQ, DQS/DQS# and DM signal. The ODT pin is ignored if the EMR (1) is programmed to disable ODT. VDD Supply Power Supply: +1.8V 0.1V VSS Supply Ground VDDL Supply DLL Power Supply: +1.8V 0.1V VSSDL Supply DLL Ground VDDQ Supply DQ Power: +1.8V 0.1V. VSSQ Supply DQ Ground VREF Supply Reference Voltage for Inputs: +0.5*VDDQ NC - No Connect: These pins should be left unconnected. |
