The SST25VF512A-33-4C-QAE device is a state-of-the-art, high-performance, low-power, serial Memory device offering ultra-fast read and write performance. This device performs monolithic dual-bit operation that allows random access of data byte locations.

Overview

The SST25VF512A-33-4C-QAE is a 16-megabit (2,097,152 words x 8 bytes) multicomponent packaged Memory device suitable for high-speed communication applications. It is based on the industry-standard Serial Flash Interface (SFI) bus, offering ultra-fast performance, extremely low power consumption, and broad-market compatibility.

This Memory device is available in a 4-pin Quad Flat No-Lead (QFN) package with densities ranging from 1-Mbit to 16-Mbits. This device is ideal for systems that require the highest-possible performance with minimum space requirements. Features include auto-program, write protection, and read protection for data security, an 01h command for protection against errant writes, and an "over-current-protection" solution that reduces power consumption.

Features

• Serial Peripheral Interface compatible with Standard SPI
• Mode 0 (0,0), Mode 1 (1,1) and Mode 2 (1,0) clock regimes
• Serial clock frequency of 33MHz
• Automatic hold and deselect when CS pin transitions High
• Multiple sectors erase command available
• Individual block write protection command available
• Automatic write protection on power down
• Write protection enabled using Write Protection Register (WPR)
• Read protection enabled using Read Protection Register (RPR)
• Auto-program function and 4-byte Address Modes
• Flexible Status Register bit programming mode

Application Field

The SST25VF512A-33-4C-QAE device is ideal for any application that requires high-speed random memory access and high-capacity storage. Its small form factor and low power consumption make it ideally suited for portable consumer applications such as digital audio players, MP3 players, digital cameras, GPS devices, and medical equipment.

It is widely used in consumer electronics, industrial, automotive, medical and defense applications due to its high performance, advanced features, and robust data security features. In addition, its built-in safe erase and write protection functions make it a popular choice for data-sensitive application such as data logging, consumer banking, and payment processing.

Working Principle

The SST25VF512A-33-4C-QAE Memory device is based on a serial peripheral interface (SPI) bus and is designed to operate with Serial Peripheral Interface (SPI) clock frequencies of up to 33MHz. This device supports the Standard Serial Peripheral Interface (SPI) bus protocol, enabling it to interface with a variety of host controllers with little effort.

The Memory device is compatible with multiple modes of operation, including Mode 0 (0,0), Mode 1 (1,1) and Mode 2 (1,0). For random accesses, the device supports an ‘Over-Current Protection’ (OCP) solution to reduce power consumption when the internal Memory is not actively used. In addition, the device supports data protection and block locking schemes to ensure secure, reliable operations.

This Memory device also features individual block write protection, over-current protection, auto-programming function and 4-byte address modes. The device also has a flexible status register bit programming mode, which allows the user to select specific sector writes and block locking while erasing or programming.

Conclusion

The SST25VF512A-33-4C-QAE Memory device is a reliable and high-performance memory device that offers multiple features and benefits to its users. With its SPI-compatible bus, four clock regimes, and data security capabilities, this device is suitable for a variety of applications. Its industry-standard packaging and quick access makes it ideal for a range of portable consumer applications.
