They conform to a variety of regulatory requirements and quality standards.

System on a chip (SoC) devices are reliable, customizable, and relatively cost-effective. The heart of systems on a chip technology is a microprocessor core or microcontroller core. System on a chip (SoC) products are relatively small, but used widely in network access and security systems; heating, ventilation and air conditioning (HVAC) systems; home automation applications; and CNC program control. Microprocessor cores or microcontroller cores contain programmable memory technology in memory blocks that communicate through channels. Because system on a chip (SoC) devices are programmable, they are suitable for intelligent applications and application specific integrated circuits (ASIC).

Timing Sources

Timing sources are directly embedded into system on a chip (SoC) devices.
