On February 3, the professional teardown organization iFixit released the teardown report of the Vision Pro, and on February 7, iFixit published a more in-depth chip-level analysis report, showing that it contains a large number of Texas Instruments (TI) chips and a NorFlash from Gigadevice.
As introduced in the previous teardown article, although the Vision Pro appears to have only one main board, it actually consists of two PCB boards connected together by a flexible PCB. After analysis, iFixit revealed the model numbers of the relevant chips on this main board.
First, let’s look at the front of the main board; it is clear that in the image below, the right side of the Vision Pro main board has a chip with the Apple logo, which is the Apple M2 processor, while the chip on the left with the Apple logo is the R1 sensor co-processor.
The M2 processor is primarily responsible for running visionOS and executing advanced computer vision algorithms, etc. The R1 co-processor mainly handles data signals from 12 cameras, 5 other types of sensors, and 6 microphones, accelerating the processing of sensor data, reducing latency to ensure real-time content presentation, and reducing the load on the main CPU to lower power consumption. Apple previously stated that the R1 chip can transmit images to the display in 12 milliseconds, achieving nearly no-latency real-time transmission.

After reviewing the Vision Pro host’s internal main board chips, iFixit also analyzed the internal main board of the external power supply for the Vision Pro.
First, let’s look at the front of the charging board:
△Red: STMicroelectronics STM32L4A6VG Arm Cortex-M4 microcontroller
Orange: Gigadevice GD25Q80E 1 MB serial NOR flash
Yellow: Texas Instruments CD3217B13 USB Type-C controller

△Red: Bosch Sensortec accelerometer
Now let’s look at the back of the charging board:
△Red: Renesas ISL9238C buck-boost battery charger
Orange: Renesas RAA489800 bidirectional buck-boost regulator
△Red: Texas Instruments TMP103A temperature sensor
Orange: Texas Instruments TMP103B temperature sensor
Finally, let’s look at the Vision Pro’s speaker main board:
△Red: Possibly Cirrus Logic CS46L11 audio codec
Yellow: Texas Instruments SN02776B0A audio amplifier
Green: Texas Instruments TPS62135 4 A buck converter
In summary, in the Vision Pro host and its matching speaker and external power supply, in addition to Apple’s self-developed processing chips, there are also several self-developed power management chips from Apple, as well as a large number of Texas Instruments chips, totaling as many as 17. Surprisingly, there is also a domestic storage chip from Gigadevice’s NorFlash chip on the Vision Pro.
