array. (Note that PEEL device programmers automatically program connections unused product terms that they will have effect output function).
Function Description
PEEL18CV8 implements logic functions sum-ofproducts expressions programmable-AND/fixed-OR logic array. User-defined functions created programming connections input signals into array. Userconfigurable output structures form macrocells further increase logic flexibility.
Programmable Macrocell
unique twelve-configuration output macrocell provides complete control over architecture each output. ability configure each output independently permits users tailor configuration PEEL18CV8 precise requirements their designs.
Architecture Overview
PEEL18CV8 architecture illustrated block diagram Figure dedicated inputs I/Os provide inputs outputs creation logic functions. core device programmable electricallyerasable array which drives fixed array. With this structure, PEEL18CV8 implement sumof-products logic expressions. Associated with each functions macrocell which independently programmed different configurations. programmable macrocells allow each create sequential combinatorial logic functions active-high active-low polarity, while providing three different feedback paths into array.
Macrocell Architecture
Each macrocell, shown Figure consists Dtype flip-flop signal-select multiplexers. configuration each macrocell determined four EEPROM bits controlling these multiplexers. These bits determine output polarity, output type (registered nonregistered) input-feedback path (bidirectional I/O, combinatorial feedback). Refer Table details. Equivalent circuits twelve macrocell configurations illustrated Figure addition emulating four PAL-type output structures (configurations 3,4,9, 10), macrocell provides eight additional configurations. When creating PEEL device design, desired macrocell configuration generally specified explicitly design file. When design assembled compiled, macrocell configuration bits defined last lines JEDEC programming file.
AND/OR LOGIC ARRAY
programmable array PEEL18CV8 (shown Figure formed input lines intersecting product terms. input lines product terms used follows:
Input Lines: input lines carry true complement signals applied input pins additional lines carry true complement values feedback input signals from I/Os product terms: product terms (arranged groups used form product functions output enable terms (one each I/O) global synchronous preset term global asynchronous clear term
Output Type
signal from array directly output (combinatorial function) latched D-type flipflop (registered function). D-type flip-flop latches data rising edge clock controlled global preset clear terms. When synchronous preset term satisfied, output register will HIGH next rising edge clock input. Satisfying asynchronous clear will LOW, regardless clock state. both terms satisfied simultaneously, clear will override preset.
each input-line/product-term intersection, there EEPROM memory cell that determines whether there logical connection that intersection. Each product term essentially 36-input gate. product term that connected both true complement input signal will always FALSE thus will affect function that drives. When connections product term opened, "don't care" state exists that term will always TRUE. When programming PEEL18CV8, device programmer first performs bulk erase remove previous pattern. erase cycle opens every logical connection array. device configured perform user-defined function programming selected connections
Output Polarity
Each macrocell configured implement active-high active-low logic. Programmable polarity eliminates need external inverters.
Output Enable
output each macrocell enabled disabled under control associated programmable output enable product term. When logical conditions programmed output enable term satisfied, output signal propagated pin. Otherwise, output buffer switched into high-impedance state. Under control output enable term,

function dedicated input, dedicated output, bidirectional I/O. Opening every connection output enable term will permanently enable output buffer yield dedicated output. Conversely, every connection intact, enable term will always logically false will function dedicated input.
Input/Feedback Select
PEEL18CV8 macrocell also provides control over feedback path. input/feedback signal associated with each macrocell obtained from three different locations; from input pin, from output flip-flop (registered feedback), directly from gate (combinatorial feedback).
Design Security
PEEL18CV8 provides special EEPROM security that prevents unauthorized reading copying designs programmed into device. security programmer, either conclusion programming cycle separate step, after device been programmed. Once security impossible verify (read) program PEEL until entire device first been erased with bulk-erase function.
Bi-directional
input/feedback signal taken from when using dedicated input bi-directional I/O. (Note that possible create registered output function with bi-directional I/O.)
Programming Support
ICT's JEDEC file translator allows easy conversion existing designs PEEL18CV8, without need redesign. supports broad range popular third party design entry systems, including Data Synario Abel, Logical Devices CUPL others. also offers (for free) proprietary PLACE software, easy-touse entry level PC-based software development system. Programming support includes popular third party programmers; Data I/O, Logical Devices, numerous others. also provides cost development programmer system, PDS-3.
Combinatorial Feedback
signal-select multiplexer gives macrocell ability feedback output gate, bypassing output buffer, regardless whether output function registered combinatorial. This feature allows creation asynchronous latches, even when output must disabled. (Refer configurations 5,6,7 Figure
