Embedded memory enhances Programmable logic for complex designs -
11/07/96 EDN-Design Feature The growing densities of PLDs are
making the chips suitable for increasingly complex designs. Those designs
require high-performance scratchpad RAM for temporary storage of data that
passes through the logic circuitry that the chips implement. Vendors are
responding with new devices.... [Design Feature by Rick Nelson, Contributing

Lattice Semi GDS Chip Programmer software - Generic Digital
Switches are in-circuit programmable devices made by Lattice Semiconductor
that allow pin to pin routing, buffering, and inversion. Perfect for making
last minute circuit changes…. (added 11/05)
LED driver provides software controlled intensity - 30-Sep-04 Issue of EDN
Recent advances in operating efficiency have expanded the use of LEDs from one of mere
indicators to becoming driving forces in electronic lighting. Increased reliability
and ruggedness (versus other lighting technologies] gives the LED a bright future
indeed. Vendors in recent years have introduced many ICs for driving LEDs, but the
problem of driving serial chains of LEDs has received less at.... [Design Idea by Neda

Make a printer port EEPROM programmer and dongle - 13-May-04 Issue of EDN
You can easily use a PC's printer port for serial-EEPROM programming. You can use a
device-programmer circuit used to program the MicroWire serial EE-PROM 93CXX (Figure
1]. The circuit is so simple that any further simplification seems impossible.
This programmer circuit contains no microcontroller, as most device programmers do....
