Royal Philips Electronics announced that Intel Corporation has selected the PMU+, Philips' recently introduced single-chip power management unit, for their Microsoft Windows Powered Smartphone concept design that was developed in partnership with Microsoft and formally announced today. The latest reference design from Intel combines Intel® Personal Internet Client Architecture (Intel PCA) with the Philips PMU+ to allow designers to add features such as color displays, wireless connectivity and streaming media to Smartphones, while reducing the size, power consumption and end-user cost. This industry collaboration is another example of Philips' technology helping people connect to information, entertainment and services anywhere and any time.
The Philips PMU+ has a unique real-time control feature that can reduce power consumption by up to 70 percent in smart phones and wireless PDAs. The control feature allows the handheld device to continuously adjust all of the power supplies in the PMU+ to the lowest voltages necessary for the functions being used in that power domain, minimizing power consumption and extending battery life. By continuously adjusting the supply voltages to each power domain (i.e. the processor, memory subsystem, display backlight, and wireless components), designers can create handheld products that include all the application features a consumer wants, while still using less power than previous models.
On a single PMU+ chip, Philips integrates a flexible on-chip battery management system, eight programmable power supplies, battery charger, a 10-bit analog-to-digital converter, touch screen interface, and other features required for wireless handheld devices. Because of this high level of integration, the chip uses 50 percent less space and costs 30 percent less than equivalent semiconductors.
Availability
The PCF50606 PMU+ and PCF50605 PMU+ use a HVQFN56 8x8x0.85 millimeter package. Engineering samples and evaluation kits for both chips are available now from Philips.
