3. A   system on a chip  or  system on chip    is an integrated circuit(also known as a "chip") that integrates all components of a computer or other electronic system. It may contain digital, analog, mixed-signal, and often  radio frequency signal processing functions, depending on the application .

5. As they are integrated on a single electronic substrate, SoCs consume much less power and take up much less area than multi-chip designs with equivalent functionality. Because of this, SoCs are very common in the mobile computing and edge computing markets.Systems on chip are commonly used in embedded systems and the Internet of Things.

7. Mobile computing based SoCs typically bundle processors, memories, on-chip caches, wireless networking capabilities and often digital camera hardware and firmware. Some mobile computing SoCs include: Apple: Apple-designed processors A12 Bionic and other A series, used in  iPhones and  iPads S series and W series, in Apple Watches. Apple T series, used in the 2016 and 2017 MacBook Pro touch bars and fingerprint scanners. Uses of soc in mobiles

8. Samsung Electronics: list, typically based on ARM7 and ARM9 Exynos, used mainly by Samsung's Galaxy series of smart phones Qualcomm: Snapdragon (list), used in many LG, Xiaomi, Google Pixel, HTC and Samsung Galaxy smart phones. In 2018, Snapdragon SoCs are being used as the backbone of laptop computers running Windows 10, marketed as "Always Connected PCs

9. Processor cores An SoC must have at least one processor core, but will typically have more. Processor cores can be a microcontroller, microprocessor (μP ),  digital signal processor (DSP) or application-specific instruction set processor(ASIP ) core . ASIPs have instruction setsthat are customized for an application domain and designed to be more efficient than general-purpose instructions for a specific type of workload.  Multiprocessor SoCs have more than one processor core by definition.

11. M emory Memory technologies for SoCs include  read-only memory (ROM ), random-access memory (RAM), electrically erasable programmable ROM (EEPROM) and flash memory .   RAMS subdivided into relatively faster but more expensive static RAM (SRAM) and the slower but cheaper dynamic RAM (DRAM).

12. I nterfaces SoCs include external interfaces, typically for communication protocols. These are often based upon industry standards such as  USB , FireWire, Ethernet, USART, SPI, HDMI,  , etc. These interfaces will differ according to the intended application.  Wireless networking protocols such as Wi-Fi, Bluetooth,  and near-field communication may also be supported.

13. Power mgmnt System-on-chip  peripherals including  counter timers , real-time timers and power-on reset generators. SoCs also include voltage regulators and power management circuits.
