Operational Amplifier (op-amp)
A high-gain voltage amplifier that has a differential input and, usually, a single output.
Printed Circuit Board (PCB)
A board that connects electronic components.
Quad Serial Peripheral Interface (QSPI)
A Serial Peripheral Interface (SPI) controller that allows the use of multiple data lines.
Receive Data (RXD)
A signal line in a serial interface that receives data from another device.
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.
System in Package (SiP)
Several integrated circuits, often from different technologies, enclosed in a single module that
performs as a system or subsystem.
Serial Peripheral Interface (SPI)
Synchronous serial communication interface specification used for short-distance communication.
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 Wire Debug (SWD)
A standard two-wire interface for programming and debugging Arm
®
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.
