DLL Turn Off. When low this input will turn off the DLL inside the device. The AC timings with the DLL turned off will
be different from those listed in this data sheet. There will be an increased propagation delay from the incidence of
C and C to DQ, or K and K to DQ as configured. The propagation delay is not a tested parameter, but will be
similar to the propagation delay of other SRAM devices in this speed grade.
No connects inside the package. Can be tied to any voltage level.
Reference Voltage input. Static input used to set the reference level for HSTL inputs and outputs as well as AC
measurement points.
Power supply inputs to the core of the device. Should be connected to a 1.8V power supply.
Ground for the device. Should be connected to ground of the system.
Power supply for the outputs of the device. Should be connected to a 1.5V power supply for HSTL or scaled to
TDO pin for JTAG
TCK pin for JTAG.
TDI pin for JTAG. An internal resistor will pull TDI to V
TMS pin for JTAG. An internal resistor will pull TMS to V
the desired output voltage.
