Glossary

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

A hardware development platform used for application development.

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

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

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

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 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.

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

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

A software application that provides facilities for software development.

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

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

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

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

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

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.

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

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

A board that connects electronic components.

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

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.

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.

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

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

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

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

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

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

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

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

A data line for tracing and logging.

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

A hardware device for asynchronous serial communication between devices.

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

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.
