These IMPACT-X circuits combine the latest Advanced Low-Power Schottky technology with proven titanium-tungsten fuses to provide reliable, high-performance substitutes for conventional TTL logic. Their easy programmability allows for quick design of custom functions and typically results in a more compact circuit board. The TIBPAL16’ C series is characterized from 0°C to 75°C. The TIBPAL16’ M series is characterized for operation over the full military temperature range of –55°C to 125°C. These devices are covered by U.S. Patent 4,410,987.

  • Programmable Logic Design Quick Start Hand Book
    Second Edition Programmable Logic Design Quick Start Hand Book By Karen Parnell & Nick Mehta January 2002 ABSTRACT Whether you design with discrete logic, base all of your designs on microcontrollers, or simply want to learn how to use the latest and most advanced programmable logic software, you will find this book an interesting insight into a different way to design. Programmable logic devices were invented in the late seventies and since then have proved to be very popular and are now one of the largest growing sectors in the semiconductor industry. Why are programmable logic devices so widely used? Programmable logic devices provide designers ultimate flexibility, time to market advantage, design integration, are easy to design with and can be reprogrammed time and time again even in the field to upgrade system functionality. This book was written to complement the popular XilinxÒ Campus Seminar series but can also be used as a stand-alone tutorial and information source for the first of your many programmable logic designs. After you have finished your first design this book will prove useful as a reference guide or quick start handbook. The book details the history of programmable logic, where and how to use them, how to install the free, full functioning design software (Xilinx WebPACKä ISE included with this book) and then guides you through your first of many designs. There are also sections on VHDL and schematic capture design entry and finally a data bank of useful applications examples. We hope you find the book practical, informative and above all easy to use.

Programming of such a device often involves placing the chip into a special programming unit, but some chips can also be configured “in-system”. Another name for FPDs is programmable logic devices (PLDs). Source: S. Brown and J.

It contains a collection of logic circuit elements that can be customized in different ways. A PLD can be viewed as a “black box” that contains logic gates and programmable switches.

  • Field Programmable Gate Array (FPGA)
    Field Programmable Gate Array (FPGA) Wae Wolf, FPGA Based “ste Desig , 2004, Prentice Hall. INTRODUCTION TO PROGRAMMABLE LOGIC • Programmable logic requires both hardware and software. • Programmable logic devices can be programmed to Perform specified logic functions by the manufacturer or by the user. • One advantage of programmable logic over fixed-function logic is that the devices use much less board space for an equivalent amount of logic. • Another advantage is that, with programmable logic, designs can be readily changed without rewiring or replacing components. • Also, a logic design can generally be implemented faster and with less cost with programmable logic than with fixed-function ICs. Types of Programmable logic Devices • Many types of programmable logic are available, ranging from small devices that can replace a few fixed-function devices to complex high-density devices that can replace thousands of fixed-function devices. • Two major categories of user-programmable logic are PLD (programmable logic device) and FPGA (field programmable gate array). • PLDs are either SPLDs (simple PLDs) or CPLDs (complex PLDs). Simple Programmable logic Devices • The SPLD was the original PLD and is still available for small-scale applications. • Generally, an SPLD can replace up to ten fixed-function ICs and their interconnections, depending on the type of functions and the specific SPLD. • Most SPLDs are in one of two categories: PAL and GAL. • A PAL (programmable array logic) is a device that can be programmed one time. It consists of a programmable array of AND gates and a fixed array of OR gates. • A GAL (generic array logic) is a device that is basically a PAL that can be reprogrammed many times.

  • Unit V Memory Devices and Digital Integrated Circuits
    UNIT V MEMORY DEVICES AND DIGITAL INTEGRATED CIRCUITS 5.1 INTRODUCTION A memory unit is a device to which binary information is transferred for storage and from which information is retrieved when needed for processing. When data processing takes place, information from memory is transferred to selected registers in the processing unit. Intermediate and final results obtained in the processing unit are transferred back to be stored in memory. Binary information received from an input device is stored in memory and information transferred to an output device is taken from memory. A memory unit is a collection of cells capable of storing a large quantity of binary information. There are two types of memories that are used in digital systems: random-access memory (RAM) and read-anly memory (ROM). RAM stores new information for later use. The Process of storing new information into memory is referred to as a memory write operation. The process of transferring the stored infomation out of memory is referred to as a memory read operation. RAM can perform both write and read operations. ROM can perfonn only the read operation. This means that suitable binary information is already stored inside memory and can be retrieved or read at any time. However, that information cannot be altered by writing. 5.2 RAM A memory unit is a collection of storage cells, together with associated circuits needed to transfer information into and out of a device. The architecture of memory is such that information can be selectively retrieved from any of its internal allocations. The time it takes to transfer information to or from any desired random location is always the same- hence the name random access memory, abbreviated RAM.
