New PortalPlayer chips cut power and size; future iPods to benefit?

PortalPlayer, which makes the chips that power all current hard drive-based iPods, today disclosed details of its next-generation PP5022 chip for portable digital media players. The PP5022 improves upon the current PP5020 chip, offering “up to triple the battery life” thanks to better power consumption. It should be noted, however, that many factors such as LCDs, hard disks, and other integrated components will have a significant impact on battery life. Currently, the 4G iPod offers 12 hours of playback time; the iPod photo 15-17 hours; and the iPod mini 18-26 hours. The PP5022 also builds on the multimedia capabilities of the 5020, with support for video playback and, like the iPod photo’s TV slideshow features, dual-screened control of video: a menu could be on the portable screen while video clips play on your TV.

In a related announcement, PortalPlayer introduced the PP5024 chip, a more limited processor intended for high-capacity flash memory-based music players. In future generations of the iPod shuffle, the PP5024 could eventually replace the SigmaTel processor Apple currently uses. There is currently no clear reason to make such a switch, however.
