SAN FRANCISCOProgrammable logic vendor QuickLogic Corp. announced a new proven system block (PSB) for its customer specific standard products (CSSPs) that the company said enables handheld mobile system developers to conserve energy through effective power management by shutting down the CPU and the CSSP between bursts of activity caused by peripheral devices.
According to QuickLogic (Sunnyvale, Calif.) the low-power Wake-up and Verify (WAV) PSB is a solution suitable for detecting and verifying the activity of these various components of the system while managing active and standby power during specific application tasks. The PSB consumes less than five microamps of current while it monitors activities and detects when to wake up the system or part of the system, QuickLogic said.
A typical application of the WAV PSB is the monitoring of an audio jackthe system waits for the insertion of headphones/earphones into a mobile device, which is often a random external occurrence within the system, QuickLogic said. Keeping the power required to service these types of activities to a minimum becomes critical to longer battery lifeparticularly for multimedia-enabled handsets, according to the company.
The WAV PSB is available immediately for inclusion in QuickLogic's CSSPs using the ArcticLink, ArcticLink II VX, PolarPro and PolarPro II solution platforms, QuickLogic said.
