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

Data Terminal Ready (DTR)

A control signal in RS-232 serial communications transmitted from data terminal equipment, such as a computer, to data communications equipment.

DTR

Development Kit (DK)

A hardware development platform used for application development.

DK

Electrostatic Discharge (ESD)

A sudden discharge of electric current between two electrically charged objects.

ESD

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

Hardware Flow Control (HWFC)

A handshaking mechanism used to prevent an overflow of bytes in modems. It uses two dedicated pins on the RS-232 connector, Request to Send and Clear to Send.

HWFC

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

Lithium-polymer (Li-Poly)

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

Li-Poly

Mass Storage Device (MSD)

Any storage device that makes it possible to store and port large amounts of data in a permanent and machine-readable fashion.

MSD

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).

Onboard (OB)

A function that is delivered on the chip microcontroller.

OB

Operational Amplifier (op-amp)

A high-gain voltage amplifier that has a differential input and, usually, a single output.

op-amp

Printed Circuit Board (PCB)

A board that connects electronic components.

PCB

Quad Serial Peripheral Interface (QSPI)

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

QSPI

Receive Data (RXD)

A signal line in a serial interface that receives data from another device.

RXD

Request to Send (RTS)

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

RTS

Root Mean Square (RMS)

An RMS meter calculates the equivalent Direct Current (DC) value of an Alternating Current (AC) waveform. A true RMS meter can accurately measure both pure waves and the more complex nonsinusoidal waves.

RMS

System in Package (SiP)

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

SiP

Serial Peripheral Interface (SPI)

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

SPI

SubMiniature Version A (SMA)

A semi-precision coaxial RF connector for coaxial cables with a screw-type coupling mechanism.

SMA

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

Serial Wire Debug (SWD)

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

SWD

Microwave coaxial connector with switch (SWF)

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

SWF

Serial Wire Output (SWO)

A data line for tracing and logging.

SWO

Transmit Data (TXD)

A signal line in a serial interface that transmits data to another device.

TXD

Universal Asynchronous Receiver/Transmitter (UART)

A hardware device for asynchronous serial communication between devices.

UART

User Information Configuration Registers (UICR)

Non-volatile memory registers used to configure user-specific settings.

UICR

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
