Barkley is the codename of the PS Vita Motion Sensor. It is also referred as "Motion" in the System Software SDK.

The Barkley name most likely refers to the microcontroller, but could also designate the whole sensing subsystem.

Hardware

The motion sensing subsystem is made of three components:

  • microcontroller
    • communicates with Kermit via ?SPI?
    • manages and samples the sensors
  • accelerometer
  • gyroscope

DEM-3000H

Two other ICs near the microcontroller with the following markings: 

 PR4100

?Gyroscope? from unknown manufacturer 

   0C9
   Y31
<QR-Code>

Unknown IC from unknown manufacturer

Note: Both unknown ICs use a font on package that looks like the STMicroelectronics font

PCH-1xxx

  • Microcontroller: STMicroelectronics 'STM32P10SoE'
    • Undocumented variant of the STM32F100
      • Features to be documented
