Glossary

The glossary contains terms and acronyms that are used in this document.

Clear to Send (CTS)

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

CTS

Dedicated Charging Port (DCP)

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

DCP

Development Kit (DK)

A hardware development platform used for application development.

DK

General-Purpose Input/Output (GPIO)

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.

GPIO

Integrated Circuit (IC)

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

IC

Integrated Development Environment (IDE)

A software application that provides facilities for software development.

IDE

Inter-integrated Circuit (I2C)

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

I2C

Internet of Things (IoT)

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.

IoT

Li-ion

Lithium-ion

Lithium-polymer (Li-Poly)

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

Li-Poly

Low-Noise Amplifier (LNA)

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

LNA

MCUboot

A secure bootloader for 32-bit microcontroller units, which is independent of hardware and operating system.

Near Field Communication (NFC)

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

NFC

NFC-A Listen Mode

Initial mode of an NFC Forum Device when it does not generate a carrier. The device listens for the remote field of another device. See Near Field Communication (NFC).

Out of Band (OOB)

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).

OOB

Over-the-Air (OTA)

Refers to any type of wireless transmission.

OTA

Power Amplifier (PA)

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

PA

Power Management Integrated Circuit (PMIC)

A chip used for various functions related to power management.

PMIC

Printed Circuit Board (PCB)

A board that connects electronic components.

PCB

Pulse Density Modulation (PDM)

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.

PDM

Pulse Width Modulation (PWM)

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.

PWM

Quad Serial Peripheral Interface (QSPI)

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

QSPI

Request to Send (RTS)

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

RTS

SEGGER Embedded Studio (SES)

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

SES

Serial Peripheral Interface (SPI)

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

SPI

Serial Wire Debug (SWD)

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

SWD

Software Development Kit (SDK)

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

SDK

Standard Downstream Port (SDP)

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

SDP

System in Package (SiP)

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

SiP

System on Chip (SoC)

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

SoC

Microwave coaxial connector with switch (SWF)

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

SWF

Universal Asynchronous Receiver/Transmitter (UART)

A hardware device for asynchronous serial communication between devices.

UART

Universal Serial Bus (USB)

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.

USB
