| + | * [[Cameras|Two Aptina MT9V113 0.3 Megapixel VGA Cameras]] |
| + | * 240MB(+16MB probably reserved for wear leveling purposes (e.g. replacing bad blocks)) eMMC NAND - Samsung KMAPF0000M-S998 Movi[[NAND]] or Samsung KLM5617EFW-B301 [[NAND]] |
| + | * 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]] |
| + | * (2) 256 x 192 3.25 Inch Displays, one of which has a resistive touch screen |
| + | * Backwards compatible with Nintendo DS games, but not GBA games due to the lack of a gameboy cartridge port. |
| + | * Integrated ARM946E-S core clocked at 133 MHz in real mode and downclocked to 66 MHz for compatibility mode. ARM7TDMI at 33 MHz. Additional CEVA XpertTeak DSP core, also running at 133 MHz |
| + | * PAIC3000D Touchscreen and sound controller - possibly a TI codec: TSC2117 |
| + | * Mitsumi (MM3317A) or TI 72071B0 or NEC UPD68878Y04 - Power management controller. (The charger circuit itself is fully analog, and closer to the charging port.) |
| + | * SD/SDHC Card slot |
| + | * [[WiFi_Module]] with integrated 128KB SPI Flash for [[NVRAM]], WiFi settings |
| + | * BPTWL - Microcontroller based on a NEC uPD78F0500 used as "Super I/O"/"Embedded controller", used for battery charge level monitoring, volume settings, power-on sequencing of various modules (SoC, Wifi, ...), basic troubleshooting of the power supplies. Controls the status LEDs in the hinge, and the camera LED (near the outer camera). |

| + | == Hardware Revisions == |
| + | === DSi === |
| + | * board C/TWL-CPU-01 (Original rev, all pictures below) |
| + | * 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... |
| + | * Suspect this is the only board where WiFi chip is available in Hybrid games like CookingCoach |
| + | * Wireless card DWM-W015 |
| | | |
− | ==Specifications== | + | === DSi RevA === |
− | *Includes a 0.3 Megapixel VGA Camera (inside hinge) and a 3 Megapixel VGA Camera Back of DSi | + | * board C/TWL-CPU-10 (Newer model, can someone provide a date or serial # range?) |
− | *256MB Internal Flash Memory | + | * CPU: TWL A. Mine is "0937 1k". My US Serial # is ~ TW43550???[8]. It was obtained around the holiday season of 2009. If yours is earlier, please update this. |
− | *(2) 3.25 Inch Displays
| + | ===== TWL-USA-1 ===== |
− | *Backwards compatible with Nintendo DS games but not GBA games as the lack of a gameboy cartridge port. | + | * It is unclear what the difference between the USA-1 and USA models is, might indicate the presence of the KLM5617EFW-B301 NAND chip |
| + | * CPU: TWL A. Mine is "1034 7m". My US-1 Serial # is ~ TW45013???[9]. |
