The PSP-2000, which was marketed as the "PlayStation Portable Slim & Lite", is the first redesign of the PlayStation Portable. It is slimmer and lighter than the original PSP, reduced from 0.91 to 0.73 inches (23 to 18.6 mm) and from 9.87 to 6.66 ounces (280 to 189 g).
The serial port was modified to accommodate a new video-out feature, making it incompatible with older PSP remote controls. Games only output to external monitors and televisions in progressive scan mode. Non-game video outputs work in either progressive or interlaced mode. USB charging was introduced and the D-Pad was raised in response to complaints of poor performance and the responsiveness of the buttons was improved.
Other changes include improved WLAN modules and micro-controller, and a thinner and much brighter LCD screen. To improve the poor loading times of UMD games on the original PSP, the internal memory was doubled from 32MB to 64MB, part of which now acting as a cache, also improving the web browser's performance.
