Tesla Model Y chip teardown: 23 modules, 120 part numbers
The Tesla Model Y has 30 electronic modules. We checked them one by one and confirmed the part number of 130 parts (120 distinct part numbers) across 23 modules. Texas Instruments (TI) accounts for 34, found in 11 modules. Another 109 parts can only be identified by brand or function for now, so no part number is listed for them.

FAQ
Which brands of chips does the Tesla Model Y use?
Among the 130 confirmed parts on this page, the most common brands are TI (34), Tesla (19), NXP (9), Analog Devices (8), Diodes (7), Marvell (6), 31 brands in all.
How many TI (Texas Instruments) chips are in the Model Y?
There are 34 confirmed TI parts across 11 modules, the most in Autopilot / FSD computer (12).
Which Model Y module uses the most chips?
Autopilot / FSD computer has the most, with 35 confirmed parts across categories such as Power management (PMIC), DC-DC / LDO, Interface / transceiver, Sensing / analog front end.
How are part numbers confirmed, and what do grades A and B mean?
Every part number is checked one by one against public teardown material. Grade A (31 parts) was read directly in a Model Y teardown; grade B is a part number matched from teardown material for the same platform and module. Parts we can only identify by brand or function are not listed on this page.
Why are some parts missing part numbers?
We catalogued 239 parts across the car. For 109 of them we can currently confirm only the brand or function, or the identification is inferred. To avoid misleading you, this page publishes only confirmed part numbers and will add more as material is updated.
Method
- Why the Model Y
- No. 1 in China’s passenger-car retail sales in September 2026 (50,359 units), and the best-documented teardown and research record: the only “hottest car” where every module, brand, part number and source can be checked line by line.
- Grade A · Teardown-verified
- Part numbers read directly from public Model Y teardown material.
- Grade B · Same platform and module
- Part numbers matched from teardown material for the same platform and module.
- Scope
- Only grade A and B parts with a confirmed part number are published; parts we can only identify by brand or function, or that are inferred, have no part number listed.
- Basis
- Checked one by one against public teardown material; the evidence and source details are kept internally by NuAxi. Model years and build locations may differ.
- Plan view
- Module positions in the top-down figure are estimated from public material and the vehicle’s dimensions. They are for orientation only and are not actual mounting coordinates.
