A teardown of Apple's iPhone 17 Pro shows a dozen-plus chip suppliers packed into one phone, with TSMC sitting at the center — good news for the Taiwanese chipmaker and the broader chip industry.

• Apple designs its own A19 Pro processor, but TSMC actually makes it, keeping Taiwan critical to Apple's in-house chip plans.
• More than 15 chip and tech companies show up inside the phone, covering computing, memory, wireless, power and sensors.
• Qualcomm still supplies the modem for the Pro model, mainly because Apple's own modem cannot yet handle the fastest 5G signals.
• Broadcom is losing ground — Apple's new N1 chip has taken over Wi-Fi and Bluetooth duties.
• Corning supplies the protective glass, Sony the camera sensor, and NXP, Texas Instruments, STMicro, Cirrus Logic, Qorvo, Skyworks and Analog Devices fill in payments, power and radio parts.

Outlook: Apple keeps pulling chip work in-house, so suppliers like Qualcomm and Broadcom face shrinking roles while TSMC's manufacturing position looks safe.
