QuickLogic Corporation (NASDAQ: QUIK), the leader in low power Customer Specific Standard Products ( CSSPs), is proud to announce the new Wake-up and Verify (WAV) Proven System Block (PSB) for inclusion in its CSSPs. The WAV PSB allows 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.
Today’s mobile system architecture typically has a CPU connecting and controlling a wide variety of wireless devices, USB peripherals, flash memory and other external devices. These peripheral devices transfer data randomly and at varying frequency, requiring the CPU to remain powered on to monitor these activities. In order to optimize user experience and battery life, it is critical to carefully manage these events and their impact on system power. Our new, very low-power WAV PSB is an excellent solution 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. As a result, developers of handheld mobile systems can deliver a much longer battery life while improving the responsiveness of the add-on devices that consumers demand.
“System architects are constantly challenged to balance system performance and user experience with system power,” said Andy Green, QuickLogic’s director of platform strategies. “With our new, very low-power WAV PSB, the system can monitor a number of inputs – waiting for activity to happen, while consuming very little power.”
A typical application is the monitoring of an audio jack - the system waits for the insertion of headphones/earphones into a mobile device, which is often a random external occurrence within the system. Keeping the power required to service these types of activities to a minimum becomes critical to longer battery life – particularly for multimedia-enabled handsets.
