Programmable logic controllers (PLCs) are the control hubs for a wide variety of automated systems and processes.

Programmable automation controllers (PAC) are compact industrial controllers used in applications such as data acquisition and control, machine vision control, and process control.

Machine controllers and monitors use electronic numeric control and monitoring interfaces for programming and calibrating computerized machinery

Field-programmable gate arrays (FPGAs) have a different architecture than SPLDs and CPLDs, and typically offer higher capacities.

Device programmers are used to program nonvolatile memory such as microcontrollers, erasable programmable read-only memory (EPROM), programmable logic devices (PLDs), programmable array logic (PAL), generic array logic (GAL) and other electrically programmable devices

System on a chip (SoC) devices are semiconductor chips with embedded components that make the chip a standalone system

Microcontrollers (MCU) are complete computer systems on a chip.
