It defines how data is stored, accessed, and managed within the memory module. Different memory formats include RAM (Random Access Memory), ROM (Read-Only Memory), and various types of flash memory. The memory format determines the speed, capacity, and functionality of the memory device, and it is crucial for compatibility with other components in a system. Understanding the memory format is essential for selecting the right memory module for a particular application or device.
EEPROM - Memory Interface
An external memory interface is a bus protocol for communication from an integrated circuit, such as a microprocessor, to an external memory device located on a circuit board.
SPI - Organization
In the context of electronic components, the parameter "Organization" typically refers to the arrangement or structure of the internal components within a device or system. It can describe how various elements such as transistors, resistors, capacitors, and other components are physically arranged and interconnected on a circuit board or within a semiconductor chip.The organization of electronic components plays a crucial role in determining the functionality, performance, and efficiency of a device. It can impact factors such as signal propagation, power consumption, thermal management, and overall system complexity. Engineers carefully design the organization of components to optimize the operation of electronic devices and ensure reliable performance.Different types of electronic components may have specific organizational requirements based on the intended application and design considerations. For example, integrated circuits may have a highly compact and intricate organization to maximize functionality within a small footprint, while larger electronic systems may have a more modular and distributed organization to facilitate maintenance and scalability.
2KX8 - Memory Width
Memory width refers to the number of bits that can be read or written to memory at one time. It is an important specification in electronic components, particularly in memory devices like RAM and cache. A wider memory width allows for greater data throughput, enabling faster performance as more data can be processed simultaneously. Memory width can vary among different types of memory and can impact both the complexity and efficiency of data handling within electronic systems.

It impacts the overall efficiency in data handling, affecting both read and write speeds in memory-related operations.
5ms - Standby Current-Max
Standby Current-Max refers to the maximum amount of current that an electronic component or device consumes while in a low-power standby mode. This parameter is critical for power management, especially in battery-operated devices, as it indicates how efficiently the device can conserve energy when not actively in use. A lower Standby Current-Max value is typically desirable, as it contributes to longer battery life and reduced energy consumption. Manufacturers specify this value to help engineers select components that meet specific power efficiency requirements in their designs.
0.000001A - Memory Density
Memory density in electronic components refers to the amount of data that can be stored in a given physical space or memory module. It is typically measured in bits or bytes per unit area, such as bits per square inch. Higher memory density means that more data can be stored in a smaller space, which is important for devices with limited physical size or power constraints. Memory density is a key factor in determining the capacity and performance of memory devices, such as RAM, ROM, and flash memory, and is a critical consideration in the design and manufacturing of electronic products.
16384 bit - Serial Bus Type
Serial bus type refers to the method by which data is transmitted between components in an electronic system using a serial communication protocol. It involves the sequential transfer of data bits over a single channel or wire, allowing for a reduced number of interconnections compared to parallel communication. Common examples of serial bus types include I2C, SPI, USB, and UART, each with its own specific protocol and applications. The choice of serial bus type can affect the speed, complexity, and power consumption of the communication between devices.
SPI - Endurance
In electronic components, "Endurance" refers to the ability of a component to withstand repeated cycles of operation without degradation in performance or failure. It is a crucial parameter, especially in components that are subjected to frequent switching or high levels of stress during operation. Endurance testing is often conducted to evaluate the reliability and durability of electronic components under real-world conditions. Components with high endurance ratings are more likely to have a longer lifespan and provide consistent performance over time. Manufacturers typically provide endurance specifications in datasheets to help engineers and designers select components that meet the required durability for their applications.

The parameter "Data Retention Time-Min" in electronic components refers to the minimum amount of time that data can be stored in a non-volatile memory device without requiring a refresh or rewrite operation to maintain its integrity. This parameter is crucial for applications where data integrity and reliability are essential, such as in embedded systems, IoT devices, and critical infrastructure. A longer data retention time indicates a more stable memory device that can retain data for extended periods without degradation or loss. It is important to consider the data retention time when selecting memory components for specific applications to ensure data reliability and longevity.
200 - Write Protection
Write protection is a feature found in electronic components, such as memory devices, that prevents data from being modified or erased. When write protection is enabled, the data stored in the component is locked and cannot be altered, ensuring the integrity and security of the information. This feature is commonly used in devices like USB flash drives, SD cards, and EEPROMs to prevent accidental data loss or unauthorized access. Write protection can be implemented through hardware mechanisms, such as physical switches or jumpers, or through software settings that restrict write access to the component.
