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.


Development Kit (DK)

A hardware development platform used for application development.


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.


Electrostatic Discharge (ESD)

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


Embedded Trace Macrocell (ETM)

A real-time trace module providing instruction and data tracing of a processor.


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.


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.


Inter-integrated Circuit (I2C)

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


Integrated Circuit (IC)

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


Integrated Development Environment (IDE)

A software application that provides facilities for software development.


Instrumentation Trace Macrocell (ITM)

An application-driven trace source that supports printf() style debugging to trace operating system and application events and generates diagnostic system information.


Lithium-polymer (Li-Poly)

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


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.


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-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).

Orthogonal Frequency Division Multiplexing (OFDM)

A type of digital transmission and a method of encoding digital data on multiple carrier frequencies.


Orthogonal Frequency Division Multiple Access (OFDMA)

A multiple access mechanism for shared medium networks based on Orthogonal Frequency Division Multiplexing (OFDM) achieved by assigning subsets of channel sub-carriers to individual users. This allows simultaneous on-air frame transmissions to or from multiple users.


Operational Amplifier (op-amp)

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


One Time Programmable (OTP) memory

A type of non-volatile memory that permits data to be written to memory only once.

OTP memory

Printed Circuit Board (PCB)

A board that connects electronic components.


Receive Data (RXD)

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


Quad Serial Peripheral Interface (QSPI)

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


Request to Send (RTS)

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


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.


Serial Clock (SCL)

A pin used by the I2C module to control the I2C bus lines.


Serial Data (SDA)

A pin used by the I2C module to control the I2C bus lines.


System in Package (SiP)

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


SubMiniature Version A (SMA)

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


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.


Serial Peripheral Interface (SPI)

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


Serial Wire Debug (SWD)

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


Microwave coaxial connector with switch (SWF)

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


Serial Wire Output (SWO)

A data line for tracing and logging.


Transmit Data (TXD)

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


Universal Asynchronous Receiver/Transmitter (UART)

A hardware device for asynchronous serial communication between devices.


User Information Configuration Registers (UICR)

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


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.
