<div>= Specifications =<br />
<br />
*[[Cameras|Includes (2) 0.3 Megapixel VGA Cameras]]<br />
*240MB(+16MB probably reserved for wear leveling purposes (e.g. replacing bad blocks)) Internal Flash Memory - Samsung kmapf0000m-S998 MOVI [[NAND]] - MMC Interface<br />
*16MB RAM - NEC uPD 46128512AF1 - DDR SRAM or a Fujitsu 128-Mbit FCRAM 82DBS08164D-70L (datasheet: http://edevice.fujitsu.com/fj/DATASHEET/e-ds/e511454.pdf mirror:[[Media:E511454.pdf]]<br />
*(2) 256 x 192 3.25 Inch Displays, one of which has a resistive touch screen<br />
*Backwards compatible with Nintendo DS games but not GBA games due to the lack of a gameboy cartridge port.<br />
*Integrated ARM7/ARM9 cores clocked at 133mhz in real mode and downclocked to 66mhz for compatibility mode.<br />
*PAIC3000D Sound Chip - possibly a TI codecs: AIC3 ????<br />
*Mitsumi (MM3317A) or TI 72071B0 - Power supply and charger circuit ????<br />

= Hardware Revisions =<br />
<br />
<br />
== DSi ==<br />
** board C/TWL-CPU-01 (Original rev, all pictures below)<br />
** CPU: TWL. The latest date code picture I could find online was "0836 1m" as shown below, however other pictures with CPU covered show the NAND codes as late as 916, so...<br />
** Suspect this is the only board where WiFi chip is available in Hybrid games like CookingCoach<br />
** Wireless card DWM-W015<br />
<br />
<br />
== DSi RevA ==<br />
** board C/TWL-CPU-10 (Newer model, can someone provide a date or serial # range?)<br />
** CPU: TWL A. Mine is "0940 2m". My US Serial # is ~ TW71848???[5]. If yours is earlier, please update this.<br />

<br />
== DSi XL ==<br />
** board C/UTL-CPU-01<br />
** CPU is TWL A<br />
** Wireless card DWM-W024<br />
