Nintendo DSi - Hardware - Technical Specifications

Technical Specifications

The DSi has more RAM and a faster CPU than the DS Lite. Developers reported the console has a native mode, which runs software specifically designed for its hardware, access to the system's extra processing and memory resources. The inclusion of a codec integrated circuit (a microchip) amplifies sound signals and converts them from digital to analog. This increases audio output, and depending on the mode, higher audio quality. Unused space on the motherboard was removed; the CPU was relocated, and the battery housing was expanded.

The camera's resolution is two-and-a-half times higher than the handheld's screens. However, their resolution is considerably lower than contemporaneous digital cameras and mobile phones. This was done to help keep their price reasonable and to maintain a preferable response time for viewing photos in quick session, particularity since numerous applications will use them.

• CPU: The DSi has two ARM architecture CPUs: ARM9 clocked at 133 MHz and ARM7 clocked at 33 MHz. Its ARM9 is twice as fast as previous models.
• RAM: 16 MB (four times as much as previous models)
• Screen resolution: 256 × 192 pixels (same as previous models)
• Cameras: 640 × 480 pixels
• Storage: 256 MB of internal flash memory with an SD card (up to 2 GB) and SDHC card (up to 32 GB) expansion slot
• Battery: Shorter than the DS Lite, regardless of brightness setting; for example, the DSi has a battery life of 9–14 hours on the lowest brightness setting, compared to the 15–19 hours of the DS Lite on the same setting. The battery is an 840 mAh internal rechargeable, compared to 1000 mAh for the DS Lite, and has a lifespan of approximately 500 cycles; after this point, it may be replaced by the user.
