The Apple S1 is the integrated computer in the Apple Watch, and it is described as a "System in Package" (SiP) by Apple Inc.[5]

Samsung is said to be the main supplier of key components, such as the RAM and NAND flash storage, and the assembly itself,[6] but early teardowns reveal RAM and flash memory from Toshiba and Micron Technology.

System-in-Package design

It uses a customized application processor that together with memory, storage and support processors for wireless connectivity, sensors and I/O constitute a complete computer in a single package. This package is filled with resin for durability.[7]

Components

From reverse engineering, the processor handling the Wi-Fi and Bluetooth is a Broadcom BCM43342[8] and the six-axis gyroscope is from STMicroelectronics.[9]

S1P

The SiP in Apple Watch Series 1 is called S1P and looks superficially identical to the S1, but in reality is an S2 minus the on-chip GPS functionality. It contains the same dual-core CPU with the same new GPU capabilities as the S2 making it about 50% faster than the S1.[11] [12]

Announcement

The S1 was announced on 9 September 2014 as part of the "Wish we could say more" event.

The S1P was announced on 7 September 2016 as part of the "See you on the 7th" event.

Launch date

The S1 made its first appearance within the Apple Watch, which arrived in April 2015.[5] [13] The S1 was discontinued with the launch of Apple Watch Series 1, containing the S1P.

The S1P was released with the Apple Watch Series 1 on 16 September 2016.
