Pin Function

Description

Doff

Input

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 Q, or K and K to Q 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.

TDO

Output

TDO pin for JTAG

TCK

Input

TCK pin for JTAG.

TDI

Input

TMS

Input

NC

No Connect

No connects inside the package. Can be tied to any voltage level

Input

Reference

Reference Voltage input. Static input used to set the reference level for HSTL inputs and

Outputs as well as AC measurement points.

Power

Supply

Power supply inputs to the core of the device. Should be connected to a 1.8V power

supply.

Ground

Ground for the device. Should be connected to ground of the system.

Power

Supply

Power supply for the outputs of the device. Should be connected to a 1.5V power supply

for HSTL or scaled to the desired output voltage.
