One microcontroller, microprocessor or DSP core(s). Some SoCs – called multiprocessor System-on-Chip (MPSoC) – include more than one processor core.

Memory blocks including a selection of ROM, RAM, EEPROM and Flash.

Timing sources including oscillators and phase-locked loops.

Peripherals including counter-timers, real-time timers and power-on reset generators.

External interfaces including industry standards such as USB, FireWire, Ethernet, USART, SPI.

Analog interfaces including ADCs and DACs.

Voltage regulators and power management circuits.
