Lattice Semiconductor has developed a display interface in the MachXO2 PLD family. Because this interface is now supported in MachXO2 devices, designers have an even lower cost and very low power alternative to implement embedded displays.
This whitepaper provides an overview of this display standard and explain...

Adding security to a device costs extra money, time, power consumption and makes everything worse. The only reason for adding security to a device is the need to improve marketing – security components help to sell more products. To participate in the evolution of Industry 4.0, the Internet of Things and cloud technologies...

Many moderate size Programmable Logic Device (PLD) designs, especially those in control plane applications, consist of a number of interfaces interconnected via an onchip bus to a microprocessor that may be on- or off-chip. Although each interface is often relatively simple, the task of building all the on-chip interconnections...

A novel approach for providing microprocessor power directly from 48V is proposed. This solution enables high voltage, low current to be distributed throughout a system, minimizing distribution losses, while providing low voltage, high current direct from the 48V input in the most efficient manner possible.
This solution...

Improvements in AC/DC power supply design are evolutionary, rather than revolutionary. It’s easy to settle for tried-and-tested approaches because no one new design technique is likely to yield great benefits. The design challenge is to establish what small enhancements can be made in various parts of the design...

Although not part of the PCI Express spec, nontransparent bridging is completely consistent with it and can support multiprocessor systems with only minimal software initialization efforts.
For PCI Express technology to realize its full potential as the interconnect solution for chip-to-chip and backplane switching...

Over the years, a number of methods have been proposed to realize fractional-N frequency synthesis that are based on the basic concepts of traditional integer-N synthesis [1,5]. Among these methods, three techniques are best known in the industry: fractional divider-based, current injection-based, and ∆Σ modulator-based...

This paper introduces a new DC/DC power supply architecture, called “Yeaman Topology”. The main characteristic of this topology is to separate the output voltage regulation function from the bulk power conversion function, implementing two stages that share a common input, and have their outputs in series....

While almost every power-supply engineer intimately knows and understands the lab setup for measuring efficiency, there are many important nuances that must be considered when measuring the efficiency of a device with ultralow quiescent current (IQ). For a device that consumes less than 1 µA, the circuit’s...
