Digital Electronics
Este proyecto está orientado a personas que ya conocen que es una FPGA por lo que sólo les diremos que se trata de circuitos electrónicos reconfigurables que permiten crear nuevos circuitos que se comportan como nosotros querramos.

Low Power Schottky (LSTTL) has become the industry standard logic in recent years, replacing the original 7400 TTL with lower power and higher speeds. In addition to offering the standard LS TTL circuits, Motorola offers the FAST Schottky and TTL family. Complete specifications for each of these families are provided in data sheet form. Functional selector guides not only provide an overview of already introduced devices but planned introduction dates of new products. .......

Logic Gates and Circuits In a digital system there are only two stable states, logic 1 and 0 (or HIGH and LOW, TRUE and FALSE, etc. ) In a popular logic family called TTL (Transistor-Transistor Logic).

FPGA and CPLD solutions from Lattice Semiconductor
Lattice is the source for innovative FPGA, PLD, programmable Power Management and Clock Management solutions. The LatticeECP3 family defines a new mid-range, value-based class of FPGAs, not only by further reducing costs, but also by reducing static power consumption by up to 80% and total power consumption by over 50% for typical designs, compared to competitive SERDES-capable FPGAs. The MachXO family of non-volatile, infinitely reconfigurable PLD devices is designed for applications tradition.......
