TechInsights Teardown: Apple Watch second generation
These devices are used across many markets such as fitness and sports training, consumer electronics and communications devices.
As technology has evolved, these devices have become smaller and more sophisticated allowing for more functionality to be packed onto a thin form factor.
One device is the Apple Watch, the smartwatch that comes from the wildly popular company of smart devices and computers. Last year, the company unveiled the second generation of the Apple Watch.
The Apple Watch has numerous electronic components from the parent company such as the applications processor, Wi-Fi chip and NFC controller. Additionally, there are SDRAM and flash memory from Micron Technology and microcontrollers from ST Microelectronics and a host of MEMS devices.
The following is a partial deep dive on the smartwatch from TechInsights.
- 1.6 inch OLED
- 1 GB mobile LPDDR4 SDRAM
- No camera
Target market: Wearables/consumer electronics
Released: September 2022
The main board of the Apple Watch second generation includes the 64-bit dual core applications processor from Apple as well as RF transceiver from Intel. Other electronic components include:
- Micron’s 1 GB mobile LPDDR4 SDRAM and 32 GB 3D NAND flash
- NXP Semiconductors’ display port multiplexor
- ST Microelectronics’ 32-bit MCU, serial EEPROM memory, DC-DC converter and MCU/eSIM with 32-bit ARM
- Texas Instruments’ load switch
- SiTime’s MEMS oscillator
- Dialog Semiconductor’s power management
- Broadcom’s wireless power receiver and custom sensing ASIC
- Qorvo’s envelop power tracker
- Apple Wi-Fi 4/Bluetooth 5.3
- Sony’s RF switch
- Skyworks’ GPS LNA with filter and LB front-end module
- Bosch Sensortec’s six-axis MEMS accelerometer and gyroscope
Microphone flex board
The microphone flex board allows for communication with the external world as well as connection to smartphones. The main component is the MEMS microphone from Knowles.
The NFC board allows for communications and payments of the smart watch to other devices such as smartphones or mobile payments. The electronic components on the board include:
- An NFC controller from Apple
- An NFC controller from NXP Semiconductors
- Ambient light sensor from AMS
