Specifications

  • 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 MoviNAND 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

DSi RevA

  • board C/TWL-CPU-10 (Newer model, can someone provide a date or serial # range?)
  • 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.
TWL-USA-1
  • 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].

DSi XL

  • board C/UTL-CPU-01
  • CPU is TWL A
  • Wireless card DWM-W024
