16 / 49 page  ZZZTXLFNORJLFFRP 4XLFN/RJLF&RUSRUDWLRQ (FOLSVH,, )DPLO\ 'DWD 6KHHW5HY % Preliminary Express lines run the length of the programmable logic uninterrupted. Each of these lines has a higher capacitance than a quad, dual, or short wire, but less capacitance than shorter wires connected to run the length of the device. The resistance will also be lower because the express wires don't require the use of "pass" links. Express wires provide higher performance for long routes or high fan-out nets. Distributed networks are described in the clock/control section. These wires span the programmable logic and are driven by "column clock" buffers. All clock network pin buffers (both Dedicated and Global) are hard wired to individual sets of column clock buffers. *OREDO3RZHU2Q5HVHW 325 The Eclipse-II family of devices features a global power-on reset. This reset is hardwired to all registers and resets them to Logic ‘0’ upon power-up of the device. In QuickLogic devices, the aynchronous Reset input to flip-flops has priority over the Set input; therefore, the Global POR will reset all flip-flops during power-up. If you want to set the flip-flops to Logic ‘1’, you must assert the “Set” signal after the Global POR signal has been deasserted. )LJXUH 3RZHU2Q 5HVHW /RZ3RZHU0RGH Power consumption of the two smaller Eclipse-II devices can be reduced significantly by de- activating the charge pumps inside the architecture. By applying 3.3 V to the Vpump pin, the internal charge pump is de-activated—this effectively reduces the dynamic power consumption of the device. Users who have a 3.3 V supply available in their system should take advantage of this low power feature by tying the Vpump pin to 3.3 V. Otherwise, if a 3.3 V supply is not available, this pin should be tied to ground. VCC Power-on Reset Q XXXXXXX 0 |
