A 16-bit Serial Flash memory called the W25Q16DVSSIG offers a small storage option for systems with constrained space, pins, and power needs. It is a member of the 25Q family and provides superior performance and versatility above and beyond that of typical Serial Flash devices. The W25Q16DVSSIG is a cutting-edge device that is made to suit the demands of contemporary embedded systems.

W25Q16DVSSIG Key features and benefits

  • Storage Capacity: The W25Q16DVSSIG can store up to 16 million bits of data, or 2MB. This gives apps with modest storage needs plenty of room to store code, speech, text, and data.
  • Low Power Consumption: The W25Q16DVSSIG uses a single 2.7V to 3.6V power supply and operates at a low current of 4 mA in active mode and 1 mA in power-down mode. This increases battery life and lowers overall power consumption, making it appropriate for applications that require low power.
  • Flexible Organization: The W25Q16DVSSIG’s memory array is divided into 8,192 programmable pages, with 256 bytes per page. This organizational structure enables effective data and parameter storage, enhancing versatility across a wide range of applications.
  • High-Performance Interface: The W25Q16DVSSIG implements the Serial Peripheral Interface (SPI) standard and provides options for dual and quad I/O as well as a high-performance dual and quad output. With fast data transmission rates that surpass conventional parallel Flash memory, it can achieve clock frequencies of up to 104 MHz. Execute-in-place (XIP) operations are made possible by the Continuous Read Mode’s reduced instruction overhead.

Functional Description of W25Q16DVSSIG:

A Serial Flash memory device called the W25Q16DVSSIG was created to offer effective and trustworthy storage options for systems with constrained space, pins, and power needs. It includes a variety of features and capabilities that improve its functionality and adaptability. The main functions and capabilities of the W25Q16DVSSIG are outlined in this functional description.

● Memory Organization

The memory array in the W25Q16DVSSIG is divided into 8,192 programmable pages, with 256 bytes per page. The flexibility in information management provided by this architecture enables efficient data storage and retrieval within the device.

The device supports the Serial Peripheral Interface (SPI) standard for read and write operations. The Read Data (03h) command enables speedy recovery of saved data by reading data from the memory. Data can be written into memory using the Page Program (02h) command and the Write Enable (06h) instruction. It is possible to program 256 bytes at once.

● Erase Operations

The W25Q16DVSSIG offers a range of erasing choices to meet a range of requirements. Sector, block, and chip erase procedures are supported. Blocks can be deleted in groups of 128 (32KB block erase), sectors can be erased in groups of 16 (4KB sector erase), or the entire chip can be erased (chip erase). Depending on the requirements of the application, this flexibility enables exact and effective data erasure.

When compared to conventional Serial Flash memory, the device’s high-performance dual or quad SPI choices enable quicker data transmission rates. Increased throughput is possible with Dual/Quad output and Dual/Quad I/O SPI modes thanks to the use of several data lines and parallel data transfer. The device’s overall performance in data-intensive applications is improved by this capability.

● Low Power Consumption

The W25Q16DVSSIG uses little power while operating from a single 2.7V to 3.6V supply. In active mode, it uses only 4 mA, which reduces power consumption and lengthens battery life in power-sensitive applications. When in power-down mode, the current consumption can be as low as 1 A, substantially lowering the amount of energy used when no one is using the device.

● Features for security and control

Additional control options and security features are offered by the device. It has two pins: a Write Protect pin and a Hold pin, which can be used to manage memory operations and guard against unauthorized changes. Options for programmable write protection enable fine-grained control of write access to particular memory regions. The flexibility of array management is further increased by top- or bottom-array control.

The W25Q16DVSSIG complies with the JEDEC standard for manufacturer and device identification, which includes a 64-bit Unique Serial Number. This compliance guarantees interoperability and standardization with other devices and makes it easier to integrate into various systems.

The W25Q16DVSSIG Serial Flash memory device offers a variety of capabilities and features that facilitate effective data management, storage, and retrieval. The W25Q16DVSSIG is a good choice for applications that need dependable and high-performance storage solutions due to its flexible memory organization, quick transfer rates, low power consumption, and control and security features.

Control Flexibility and Security Features

The W25Q16DVSSIG Serial Flash memory device offers control flexibility and security features to enhance its functionality and protect data integrity.

Hold Pin and Write Protect Pin

Hold Pin

The Hold pin enables the momentary suspension of ongoing activities while maintaining the device’s present state. It permits interruptions without corrupting or losing data.

Write Protect Pin

When asserted, the Write Protect (WP) pin stops write operations, protecting data from unauthorized changes or unintentional overwriting.

The device features programmable write protection, allowing users to choose particular memory blocks or areas that are shielded from write operations. This feature ensures the integrity and confidentiality of the data.

User configuration of the memory structure can be done by choosing top or bottom array control.

  • Top Array Control: Useful for segregating the storage or access of particular data or code. It accesses memory from the top area.
  • Bottom Array Control: Useful when distinct sorts of data or code need their own specific areas of memory since it accesses them from the bottom.
  • These features give customers alternatives for customization, data protection, and control flexibility, enabling effective data management and safe operations.
