XC2C64A-7VQG100C IC CPLD 64MC 6.7NS 100VQFP

Kev piav qhia

CoolRunner-II 64-macrocell ntaus ntawv yog tsim los rau ob qho tib si kev ua haujlwm siab thiab kev siv hluav taws xob tsawg.Qhov no qiv nyiaj txuag hluav taws xob rau cov khoom siv sib txuas lus siab thiab kev kub ceev rau cov khoom siv roj teeb.Vim tias lub zog qis qis thiab kev ua haujlwm tsis muaj zog, tag nrho cov kev ntseeg tau zoo tuaj.Cov cuab yeej no muaj plaub qhov Kev Ua Haujlwm Blocks sib cuam tshuam los ntawm lub zog qis Advanced Interconnect Matrix (AIM).Lub AIM pub 40 qhov tseeb thiab ntxiv cov tswv yim rau txhua qhov Kev Ua Haujlwm Block.Cov Txheej Txheem Ua Haujlwm muaj xws li 40 los ntawm 56 P-lub sij hawm PLA thiab 16 macrocells uas muaj ntau yam kev teeb tsa uas tso cai rau kev sib xyaw ua ke lossis sau npe ua haujlwm.Tsis tas li ntawd, cov ntawv sau npe no tuaj yeem rov pib dua lossis ua ntej thiab teeb tsa raws li D lossis T flip-flop lossis raws li D latch.Kuj tseem muaj ntau lub cim moos, ob qho tib si thoob ntiaj teb thiab cov khoom lag luam hauv zos cov ntsiab lus, teeb tsa ntawm ib lub hauv paus macrocell.Output pin configurations muaj xws li slew rate limit, bus tuav, rub-up, open drain, thiab programmable grounds.Ib tug Schmitt trigger input muaj nyob rau ntawm ib tug input tus pin hauv paus.Ntxiv nrog rau kev khaws cov ntaub ntawv tso tawm macrocell, cov ntawv sau npe macrocell tuaj yeem teeb tsa raws li "direct input" sau npe khaws cov cim ncaj qha los ntawm cov tswv yim pins.Lub moos muaj nyob rau ntawm lub ntiaj teb lossis Function Block hauv paus.Peb lub moos ntiaj teb no muaj nyob rau txhua qhov Function Blocks raws li lub moos synchronous.Cov ntawv sau npe Macrocell tuaj yeem tsim kho tus kheej kom muaj zog mus rau xoom lossis ib lub xeev.Lub ntiaj teb teeb tsa / rov pib tswj kab kuj tseem muaj rau asynchronously teem lossis rov pib xaiv cov npe thaum lub sijhawm ua haujlwm.Ntxiv lub moos hauv zos, synchronous moos-pab kom, asynchronous teeb / rov pib dua, thiab tso zis tso cai rau cov teeb liab tuaj yeem tsim siv cov ntsiab lus khoom ntawm ib-macrocell lossis per-Function Block hauv paus.DualEDGE flip-flop feature kuj muaj nyob rau ntawm ib lub hauv paus macrocell.Cov yam ntxwv no tso cai rau kev ua haujlwm siab synchronous ua haujlwm raws li qis zaus clocking los pab txo tag nrho lub zog siv ntawm lub cuab yeej.Lub CoolRunner-II 64-macrocell CPLD yog I / O tau tshaj LVTTL thiab LVCMOS18, LVCMOS25, thiab LVCMOS33.Cov cuab yeej no tseem yog 1.5VI / O tau tshaj nrog kev siv Schmitt-trigger inputs.Lwm qhov tshwj xeeb uas yooj yim txhais lus voltage yog I / O banking.Ob lub tsev txhab nyiaj I/O muaj nyob rau ntawm CoolRunner-II 64A macrocell ntaus ntawv uas tso cai yooj yim cuam tshuam rau 3.3V, 2.5V, 1.8V, thiab 1.5V li.
