Similarly, 74151 8-to-1 multiplexer consumes less than over 1,000 product terms CY7C342B. This allows designer replace more packages with just EPLD. family comes range densities, shown below. standardizing building blocks, designer replace hundreds different 7400 series part numbers currently used most digital systems. family based architecture flexible macrocells grouped together into Logic Array Blocks (LABs). Within group additional product terms called expander product terms. These expanders used shared macrocells, allowing complex functions product terms easily implemented single macrocell. Programmable Interconnect Array (PIA) globally routes signals within devices containing more than LAB. This architecture fabricated Cypress 0.8-micron, double-layer-metal CMOS EPROM process, yielding devices with significantly higher integration, density system clock speed than largest previous generation EPLDs. CY7C34XB devices 0.65-micron shrinks original 0.8-micron family. CY7C34XBs offer faster speed bins each device Cypress family. density performance CY7C340 family accessed using Cypress's Warp2 Warp3 design software.

Functional Description
Logic Array Block logic array block, shown Figure heart architecture. consists macrocell array, expander product term array, block. number macrocells, expanders, vary, depending upon device used. Global feedback signals provided within LAB, giving each functional block complete access resources. itself programmable interconnect array dedicated input bus. feedbacks macrocells pins feed PIA, providing access them through other LABs device. members CY7C340 family EPLDs that have single global bus, needed (see Figure Macrocell Traditionally, PLDs have been divided into either (programmable AND, programmable OR), PAL® (programmable AND, fixed architectures. PLDs latter type provide faster input-to-output delays, inefficient fixed allocation product terms. Statistical analysis logic designs shown that logic functions (per macrocell) require three product terms less. macrocell structure been optimized handle variable product term requirements. shown Figure each macrocell consists product term array configurable register. macrocell, combinatorial logic implemented with three product terms ORed together, which then feeds gate. second input gate also controlled product term, providing ability control active HIGH active logic implement JK-type flip-flops.

more product terms required implement given function, they added macrocell from expander product term array. These additional product terms added macrocell, allowing designer build gate-intensive logic, such address decoders, adders, comparators, complex state machines, without using extra macrocells. register within macrocell programmed either operation. alternately configured flow-through latch minimum input-to-output delays, bypassed entirely purely combinatorial logic. addition, each register supports both asynchronous preset clear, allowing asynchronous loading counters shift registers, found many standard functions. These registers clocked with synchronous system clock, clocked independently from logic array. Expander Product Terms expander product terms, shown Figure dedicated input bus, programmable interconnect array, macrocell feedback, expanders themselves, feedbacks. outputs expanders then each every product term macrocell array. This allows expanders "shared" product terms logic array block. expander feed macrocells LAB, even multiple product terms same macrocell. Since these expanders feed secondary product terms (preset, clear, clock, output enable) each macrocell, complex logic functions implemented without utilizing another macrocell. Likewise, expanders feed shared other expanders, implement complex multilevel logic input latches.

Block Separate from macrocell array control block LAB. Figure shows block diagram. three-state buffer controlled macrocell product term drives pad. input this buffer comes from macrocell within associated LAB. feedback path from feed other blocks within LAB, well PIA. decoupling pins from flip-flops, registers "buried," allowing pins used dedicated outputs, bidirectional outputs, additional dedicated inputs. Therefore, applications requiring many buried flip-flops, such counters, shift registers, state machines, longer consume both macrocell register associated pin, earlier devices. Programmable Interconnect Array density speed traditionally been limited signal routing; i.e., getting signals from macrocell another. smaller devices, single array used signals available macrocells. devices increase density, number signals being routed becomes very large, increasing amount silicon used interconnections. Also, because signal must global, added loading internal connection path reduces overall speed performance device. architecture solves these problems. based concept small, flexible logic array blocks that, larger devices, interconnected PIA. solves interconnect limitations routing only signals needed each LAB. architecture designed that every signal chip within PIA. then programmed give each access signals that requires. Consequently, each receives only signals needed. This effectively solves routing problems that arise design without degrading performance device. Unlike masked programmable gate arrays, which induce variable delays dependent routing, fixed delay from point point. This eliminates undesired skews among logic signals, which cause glitches internal external logic.
