Apple Pencil internal exploration: 15 semiconductor components

According to foreign media AppleInsider, in order to make the iPad Pro more practical, Apple has equipped it with a simple design stylus - Apple Pencil, but the internal structure of this pen is not so simple.

Apple Pencil has a length of 176mm, a thickness of 9mm and weighs only 1g. After dismantling, it was found that the pen has 15 semiconductor components built in, and the well-known hardware blog Chipworks said: "It is incredible to make some components so small."

Apple Pencil's main suppliers are Texas Instruments and STMicroelectronics, and other suppliers include Maxim Semiconductor, British chipmaker CSR, analog semiconductor company SiTIme, Bosch and Fairchild.

In addition, Chipworks also found Apple's own components, package number "8529043/343S00008-A1", 343S is the standard Apple component identification code. Based on current information, Apple's internal driver ICs are designed and manufactured by STMicroelectronics.

In the plastic case of Apple Pencil, there is also a tubular lithium-ion battery with a capacity of 0.329Wh, a battery life of 12 hours, and a charge of 15 seconds for more than half an hour.

Small electronic instrument using non-electric measuring principle. It consists of load-bearing table, scale body, weighing Sensor, Weighing display, stabilized voltage power supply and other parts (Figure 2). When weighing, the measured object weight is converted into electrical signal through weighing sensor, and after being amplified by operational amplifier and processed by single chip microprocessor, the weighing value is displayed in digital form. Electronic platform scale can be placed on hard ground or installed in foundation pit for use. It has the characteristics of light weight, convenient movement, multiple functions, cable connection between the display and the scale body, and can be placed as needed during use, etc. In addition to the functions of weighing, peeling weight, accumulative weight and so on, it can also be connected with the actuator, set the upper and lower limit to control the fast and slow feeding, and can be used for small packages of batching scale or batch scale. The main specifications of China Electronic Platform Scale are shown in the table.
