Specifications
- TypeParameter
- Mounting Type
The "Mounting Type" in electronic components refers to the method used to attach or connect a component to a circuit board or other substrate, such as through-hole, surface-mount, or panel mount.
Surface Mount - Package / Case
refers to the protective housing that encases an electronic component, providing mechanical support, electrical connections, and thermal management.
73-VFQFN Dual Rows, Exposed Pad - Operating Temperature
The operating temperature is the range of ambient temperature within which a power supply, or any other electrical equipment, operate in. This ranges from a minimum operating temperature, to a peak or maximum operating temperature, outside which, the power supply may fail.
-40°C~105°C - Packaging
Semiconductor package is a carrier / shell used to contain and cover one or more semiconductor components or integrated circuits. The material of the shell can be metal, plastic, glass or ceramic.
Tape & Reel (TR) - Part Status
Parts can have many statuses as they progress through the configuration, analysis, review, and approval stages.
Active - Moisture Sensitivity Level (MSL)
Moisture Sensitivity Level (MSL) is a standardized rating that indicates the susceptibility of electronic components, particularly semiconductors, to moisture-induced damage during storage and the soldering process, defining the allowable exposure time to ambient conditions before they require special handling or baking to prevent failures
3 (168 Hours) - TypeTxRx + MCU
- Voltage - Supply
Voltage - Supply refers to the range of voltage levels that an electronic component or circuit is designed to operate with. It indicates the minimum and maximum supply voltage that can be applied for the device to function properly. Providing supply voltages outside this range can lead to malfunction, damage, or reduced performance. This parameter is critical for ensuring compatibility between different components in a circuit.
1.7V~5.5V - Frequency
In electronic components, the parameter "Frequency" refers to the rate at which a signal oscillates or cycles within a given period of time. It is typically measured in Hertz (Hz) and represents how many times a signal completes a full cycle in one second. Frequency is a crucial aspect in electronic components as it determines the behavior and performance of various devices such as oscillators, filters, and communication systems. Understanding the frequency characteristics of components is essential for designing and analyzing electronic circuits to ensure proper functionality and compatibility with other components in a system.
2.4GHz - Memory Size
The memory capacity is the amount of data a device can store at any given time in its memory.
512kB Flash 128kB RAM - Protocol
In electronic components, the parameter "Protocol" refers to a set of rules and standards that govern the communication between devices. It defines the format, timing, sequencing, and error checking methods for data exchange between different components or systems. Protocols ensure that devices can understand and interpret data correctly, enabling them to communicate effectively with each other. Common examples of protocols in electronics include USB, Ethernet, SPI, I2C, and Bluetooth, each with its own specifications for data transmission. Understanding and adhering to protocols is essential for ensuring compatibility and reliable communication between electronic devices.
Bluetooth v5.1, Thread, Zigbee® - Power - Output
Power Output in electronic components refers to the amount of electrical power that a device can deliver to a load. It is typically measured in watts and indicates the effectiveness of the component in converting electrical energy into usable work or signal. Power Output can vary based on the component's design, operating conditions, and intended application, making it a critical factor in the performance of amplifiers, power supplies, and other electronic devices. Understanding the Power Output helps in selecting appropriate components for specific applications to ensure efficiency and reliability.
8dBm - Sensitivity
Sensitivity in electronic components refers to the degree to which the output of a device responds to changes in input. It indicates how effectively a component translates a specific input signal into an observable output. High sensitivity means that even small variations in input can produce significant changes in output, making the device more responsive to signals. Sensitivity is crucial in applications where precise measurements or signal detection are required.
-103dBm - Data Rate (Max)
Data Rate (Max) refers to the maximum rate at which data can be transferred or processed within an electronic component or device. It is typically measured in bits per second (bps) or megabits per second (Mbps). This parameter is important for determining the speed and efficiency of data transmission or processing in various electronic applications such as computer systems, networking devices, and memory modules. A higher data rate indicates that the component is capable of handling larger volumes of data at a faster pace, leading to improved performance and responsiveness in electronic systems. It is crucial to consider the Data Rate (Max) specification when selecting electronic components to ensure compatibility and optimal functionality for specific applications.
2Mbps - Serial Interfaces
A serial interface is a communication interface between two digital systems that transmits data as a series of voltage pulses down a wire. Essentially, the serial interface encodes the bits of a binary number by their "temporal" location on a wire rather than their "spatial" location within a set of wires.
ADC, I2S, PWM, SPI, UART, USB - Current - Receiving
Current - Receiving refers to the amount of electrical current that an electronic component or device is capable of accepting from a power source or another component in a circuit. It indicates the maximum current that can be safely received without causing damage or malfunction. This parameter is crucial for ensuring compatibility and reliability in electronic designs, as exceeding the rated receiving current can lead to overheating or failure of the component.
5.96mA - Current - Transmitting
Current - Transmitting is a parameter used to describe the maximum amount of electrical current that an electronic component can handle while in the transmitting mode. This parameter is crucial for components such as transistors, diodes, and integrated circuits that are involved in transmitting signals or power within a circuit. Exceeding the specified current transmitting rating can lead to overheating, component failure, or even damage to the entire circuit. Designers and engineers must carefully consider this parameter when selecting components to ensure the reliability and performance of the electronic system.
16.1mA - GPIO
GPIO stands for General Purpose Input/Output. It is a type of electronic pin found on microcontrollers, microprocessors, and other integrated circuits that can be configured to either input or output digital signals. GPIO pins can be used to connect and communicate with external devices such as sensors, LEDs, motors, and more. They provide a flexible way to interact with the physical world by allowing the device to both receive and send digital signals. GPIO pins can be programmed and controlled by software to perform various functions based on the specific requirements of the electronic system.

NRF52833 Bluetooth Direction Finding
A radio capable of Bluetooth® Direction Finding is included in the nRF52833. With Direction Finding, positioning solutions can rely on not just the received signal strength indicator (RSSI), but also the signal's true direction. This enhances precision and expands the range of applications available in this market. The angle of arrival (AoA), which calculates the direction of the received signal, and angle of departure (AoD), which calculates the direction of the transmitted signal, are the two sorts of methods for detecting direction.
