Programmable Array Logic
Programmable Logic Dahasheet Guide. They are very handy little devices and can save a lot of work in building small computers. Programmable Array Logic PAL is a family of programmable logic device semiconductors used to implement logic functions in digital circuits introduced by Monolithic MemoriesInc.
The programmable logic plane is a programmable read-only memory PROM array that allows the signals present on the devices pins or the logical complements of those signals to be routed to an output logic macrocell. In addition to single-unit device programmers, vatasheet feeders and gang programmers were often used when more than just a few PALs needed to be programmed.
April [February ]. His experience with standard logic led him to believe that user programmable devices would be more attractive to users if the devices were designed to replace standard logic.
They are Programmable Array Logic chips. From Wikipedia, the free encyclopedia. Each output could have up to 8 product terms effectively AND gateshowever the combinational outputs used one of the terms to control a bidirectional output buffer. Fri Apr 23, 7: After fusing, the outputs of the PAL could be verified if test vectors were entered in the source file.
Another large programmable logic device is the ” field-programmable gate array ” or FPGA. Previous topic Next topic. These were computer-assisted design CAD now referred to as ” electronic design automation ” programs which translated or “compiled” the designers’ logic equations into binary fuse map files used datasheef program and often test each device. Fri Apr 30, 1: If you needed to determine chip selects for more than that, you could go with a larger GAL like a 22V10 or chain two 16V8s together.
They are useful for building address selectors for implementing a memory map on a processor – you could literally take A8-A15 from aand program the GAL to output chip selects for up to 8 address ranges anywhere in memory, on a page boundary.
This page was last edited on 11 Decemberat Please check the data sheet. In most applications, electrically-erasable GALs are now deployed as pin-compatible direct replacements for one-time programmable PALs. It was the first commercial design tool that supported multiple PLD families. Wikimedia Commons has media related to Programmable Array Logic.

The trademark is currently held by Lattice Semiconductor. National Semiconductor was a “second source” of GAL parts. Any help would be apprieciated. MMI made the source code available to users at no cost. Wed Apr 28, 4: PAL devices have arrays of transistor cells arranged in a “fixed-OR, programmable-AND” plane used to implement ” sum-of-products ” binary logic equations for each of the outputs in terms of the inputs and either synchronous or asynchronous feedback from the outputs.
I don’t know binary and am only beginning with assembly. Another factor limiting the acceptance of the FPLA was the large package, a mil 0.
United States Patent and Trademark Office online database. The 16L8 has no internal state, and few enough inputs that it’s practical to wire up switches and LEDs and write the truth table by hand.
If they were “rescued” from boards, they will already be programmed. A 16V8 GAL has up to 16 inputs and up to 8 outputs.

Unless they happen to be programmed in a way that you can use, they’ll datazheet useless. Retrieved from ” https: I did that once in my previous job: Could anyone tell me what the heck these things are? For large volumes, electrical programming costs could be eliminated by having the manufacturer fabricate a custom metal mask used to program the customers’ patterns at the time of manufacture; MMI used the term ” hard array logic ” HAL to refer to devices programmed in this way.
Using specialized machines, PAL devices were “field-programmable”. For example, one dqtasheet not get 5 registered outputs with 3 active high combinational outputs. Here is the link:
