According to iFixit.com (source):

Type Name Datasheet Source
SoC Nintendo 1048 0H (Custom): CPU, GPU & DSP all on one chip. N/A N/A
Processor Core ARM11 Multiprocessor Core 2x 268 MHz N/A [1]
GPU Digital Media Professionals Pica 268MHz N/A [2]
FCRAM 2x64MB Fujitsu MB82M8080-07L [3] [4]

Infrared IC NXP infrared IC, "S750 0803 TSD031C" N/A [8]
Auxiliary Microcontroller UC CTR, custom Nintendo microcontroller N/A N/A

Datasheet for memory is for a chip in the same series, it has less memory than the one inside the 3DS (128mbits vs 512mbits).

There is a trove of data on the FCC website at [9].

SDIO interface is colored red:

  • CLK
  • CMD
  • D0, D1, D2, D3

This is the interface for the 'NEW' WiFi module (based on Atheros AR6002) first included in DSi.

The proprietary and by now ancient DS-mode WiFi is colored yellow, pins are unknown.

I2C eeprom is colored blue:

  • SCL
  • SDA

SPI Flash is colored purple:

  • CLK
  • CS#
  • SI
  • SO
  • WP#
  • NC

Auxiliary Microntroller

CTR UC.png

Monitors HOME button, WiFi switch, 3D slider, volume control slider. Controls LEDs, various power supplies.

Devices attached to I2C bus:

  • UC (master?)
  • Accelerometer (slave address 0x18)
  • SoC (master? slave?)
