eeTechBriefs –
15-Minute on-demand multimedia web casts covering the latest product developments.
Join Mike Brogley of Actel Corporation for an eeTECHbrief overview of Actel’s Mixed-Signal Power Manager (MPM) using the Fusion mixed-signal flash-based FPGA. Mike covers the concepts of power management, MPM features, the interactive MPM graphical user interface used to configure the Fusion device without reprogramming the Fusion mixed-signal FPGA circuitry, and the capabilities of MPM on the Fusion Advanced Development Kit hardware. If you need power management, power-up and power-down sequencing, or power trimming and data logging, learn about the flexible reprogrammable low power FPGA-based MPM solution today.
Over the past decade, standards for up-screening commercial devices to meet higher temperature, military and space-level requirements have increased, making it a risky and potentially costly practice. Although this practice is not condoned by component manufacturers such as Maxim, the reality is that many OEMs shoulder these risks and actively engage in up-screening.
Join Maxim’s John O’Boyle for an on-demand Web Seminar devoted to exploring the risks, costs and design ramifications associated with up-screening and how to mitigate these risks with simple, cost-effective solutions. Discussion topics include:
- Known and hidden up-screening costs
- Risks of up-screening
- Metal migration
- Impact on operating life
- Ruggedized plastic with SnPb finish standard - lead-free optional - 100% burned-in and tri-temp tested (room temp, 125 degrees C, and -55 degrees C)
- Test programs tighter than the data sheet limits
Don’t miss this opportunity to learn how Maxim ruggedized plastic devices can improve system reliability in electrically stressful environments in applications that demand high-temperature performance and enhanced reliability such as mobile military and aerospace systems.
