Description

The 70T3319 is a high-speed 256K x 18 bit synchronous Dual-Port RAM that has been optimized for applications having unidirectional or bidirectional data flow in bursts. An automatic power down feature, controlled by CE0 and CE1, permits the on-chip circuitry of each port to enter a very low standby power mode. The 70T3319 can support an operating voltage of either 3.3V or 2.5V on one or both ports, controllable by the OPT pins. The power supply for the core of the device (VDD) is at 2.5V.

  1. 70T3319 SRAM what to do with unused JTAG interface pins

    Hello, If we decide not to use the JTAG pins (TDI,TDO,TCK and TMS) how should we treat these pins? e.g. pull down or pull up resistor? Floating?  Thank you for any input, Sam
