-  Official Documentation
- , According to iFixit.com (source):
- 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 .
There is one FCRAM (Fast Cycle RAM) IC in the 3DS, produced by Fujitsu and branded as MB82M8080-07L. The Fujitsu MB82M8080-07L chip internally contains 2 dies, where each die is branded MB81EDS516545 and MB82DBS08645.
The MB81EDS516545 die is a CMOS Fast Cycle Random Access Memory (FCRAM*) with Low Power Double Data Rate (LPDDR) SDRAM Interface containing 512MBit storage accessible in a 64-bit format. The MB81EDS516545 is suited for consumer applications requiring high data bandwidth with low power consumption.
NAND dumping has been successful, but the image is encrypted.
WiFi dongle pinout
SDIO interface is colored red:
- 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:
SPI Flash is colored purple:
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?)
