Glossary

In flow control, the receiving end is ready and telling the far end to start sending.

A downstream port on a device that outputs power through a USB connector but is not capable of enumerating a downstream device.

A hardware development platform used for application development.

A digital signal pin that can be used as input, output, or both. It is uncommitted and can be controlled by the user at runtime.

A semiconductor chip consisting of fabricated transistors, resistors, and capacitors.

A software application that provides facilities for software development.

A multi-master, multi-slave, packet-switched, single-ended, serial computer bus.

Physical objects that are embedded with sensors, processing ability, software, and other technologies that connect and exchange data with other devices and systems of the Internet or other communications networks.

A rechargeable battery of lithium-ion technology using a polymer electrolyte instead of a liquid electrolyte.

In a radio receiving system, an electronic amplifier that amplifies a very low-power signal without significantly degrading its signal-to-noise ratio.

A standards-based short-range wireless connectivity technology that enables two electronic devices to establish communication by bringing them close to each other.

A communication channel that is outside of the defined activity. For example, in Bluetooth® Low Energy, Out of Band pairing can be used to share encryption keys or authentication data using a different communication channel (such as NFC).

Refers to any type of wireless transmission. For Matter, OTA is synonymous with the Over-the-Air software update mechanism.

A device used to increase the transmit power level of a radio signal.

A chip used for various functions related to power management.

A board that connects electronic components.

A form of modulation used to represent an analog signal with a binary signal where the relative density of the pulses corresponds to the analog signal's amplitude.

A form of modulation used to represent an analog signal with a binary signal where the switching frequency is fixed, and all the pulses corresponding to one sample are contiguous in the digital signal.

A Serial Peripheral Interface (SPI) controller that allows the use of multiple data lines.

In flow control, the transmitting end is ready and requesting the far end for a permission to transfer data.

A cross-platform Integrated Development Environment (IDE) for embedded C/C++ programming with support for Nordic Semiconductor devices, produced by SEGGER Microcontroller.

Synchronous serial communication interface specification used for short-distance communication.

A standard two-wire interface for programming and debugging Arm® CPUs.

A set of tools used for developing applications for a specific device or operating system.

A downstream port on a device that complies with the USB 2.0 definition of a host or hub.

Several integrated circuits, often from different technologies, enclosed in a single module that performs as a system or subsystem.

A microchip that integrates all the necessary electronic circuits and components of a computer or other electronic systems on a single integrated circuit.

A small, RF surface-mount switch connector series for wireless applications.

A hardware device for asynchronous serial communication between devices.

An industry standard that establishes specifications for cables and connectors and protocols for connection, communication, and power supply between computers, peripheral devices, and other computers.
