The output enable mux is software selectable with the OE option including: The XPLA3 architecture follows a timing model fpld allows. CoolRunner-II handles them all.

The bottom two waveforms for Divide by 2 and Divide by 16 show the timing when the delay zilinx enabled or the delay bit is set to 1. Each input pin can be optionally selected to participate or not. XPLA3 family offers true pin-to-pin speeds of 5. Workstation or PC Serial Port.

Technology & Architecture

If the macrocell is configured as a latch, the register. More on this later. The muxes are programmed to select as needed by the design software. Vcc can be 1. Also, there is an interactive LCD interface and more architectire adding in external busing to permit add-on goodies- like cameras, GPS units, telephones, b interfaces and so-forth.


JTAG port pins enabled.

The clock divider circuit will actually improve a poor duty cycle on an incoming clock. Data would typically be loaded onto the latched parallel outputs of Boundary-scan Shift Register. The green label at the bottom of the diagram shows the output changing at 2x the previous output data rate.

See individual device data sheets for specific device measurements. Critical here is simply getting the voltage right and being fast enough to not skew the signals to 5 nanoseconds TPD is usually fast enough.

The other mux selects from the output of the register or. Available in commercial grade and extended voltage. If you wanted to, all but one input could be attached letting you get very close to the origin of the ICC vs frequency curve.

Serial input pin selects the JTAG instruction mode. Xcr364xl of these flip-flops can be clocked from any one of eight. To make this website work, we log user data and share it with processors. There are two muxed paths to the ZIA.


Each function block has 16 macrocells. Array family of CPLDs is targeted for low power systems. There is slew rate control. Each macrocell register can be configured as. Distribute divided clock globally then double locally at macrocell Decrease Icc on global clock nets Use 2x clocking for double data archtiecture DDR applications No additional insertion delay This is a macrocell level feature.

Note that divide by 2, 4, 6, 8, 10, 12, 14, and 16 are available.

This improves noise margin at very low logic signal levels and improves the ability to make clocks with minimal external circuitry maybe on the clocks. The Idcode instruction permits blind interrogation of the components assembled. The cookrunner supply voltage must rise monotonically. XPLA3 supports the test reset functionality through the use.
