MXIC MX25V2033FM1I 2Mbit CMOS MXSMIO® Serial NOR Flash Memory

Shenzhen Mingjiada Electronics Co., Ltd., as a professional supplier in the field of electronic components, specialises in providing high-quality MX25V2033FM1I 2Mbit CMOS MXSMIO® serial NOR flash memory. This MX25V2033FM1I has gained widespread recognition in industries such as industrial control, consumer electronics, and communication equipment due to its outstanding performance, stable quality, and broad application scenarios.

Product Overview and Core Technology of MX25V2033FM1I

The MX25V2033FM1I is a high-performance 2Mbit (256K x 8) serial NOR flash memory device that employs advanced CMOS MXSMIO® (Serial Multi-Input/Output) technology to provide a reliable code storage solution for various embedded systems. The MX25V2033FM1I belongs to the MX25V series and is packaged in a standard SOP-8 package, featuring a compact size that is ideal for space-constrained applications.

In terms of core architecture, the MX25V2033FM1I is internally configured as a 262,144 x 8 structure, supporting flexible access modes. In four-input/output mode, the structure can be configured as 524,288 bits x 4 or 1,048,576 bits x 2, offering high adaptability for different application requirements. This multi-I/O mode support significantly enhances data transfer efficiency, making the product particularly outstanding in systems requiring fast startup and efficient data read/write operations.

The MX25V2033FM1I memory uses a Serial Peripheral Interface (SPI) and an optimised software protocol, allowing it to operate via a simple three-wire bus in single I/O mode. The three main bus signals include clock input (SCLK), serial data input (SI), and serial data output (SO), while the device's serial access is controlled by the CS# input. In dual I/O read mode, the SI and SO pins are renamed SIO0 and SIO1, respectively, for address/dummy bit input and data output; in quad I/O mode, the SI, SO, WP#, and HOLD# pins are renamed SIO0-SIO3, further expanding functionality.

Key Technical Specifications and Performance Features of the MX25V2033FM1I

The MX25V2033FM1I boasts several outstanding technical features that set it apart from its peers. The device supports a wide operating voltage range of 2.3V to 3.6V, making it suitable for various power supply environments. It achieves a maximum clock frequency of 80MHz, enabling extremely high data transfer rates in quad-I/O mode. In terms of write cycle time, word write takes only 50µs, and page write takes 10ms, ensuring efficient data update capabilities.

The MX25V2033FM1I employs advanced storage technology with the following notable features:

Multi-I/O support: Fully supports single I/O, dual I/O, and quad I/O modes, allowing flexible configuration based on application requirements

In terms of reliability metrics, the MX25V2033FM1I performs exceptionally well. Data retention lasts up to 20 years, ensuring data integrity for long-term use. The MX25V2033FM1I uses non-volatile storage technology, ensuring data is not lost after power loss, providing reliability for critical applications. Additionally, the MX25V2033FM1I complies with RoHS3 environmental standards, meeting modern electronic product environmental requirements.

Application Areas and Market Advantages of the MX25V2033FM1I

The MX25V2033FM1I has found widespread application across multiple fields due to its high performance and reliability. In industrial control systems, it is commonly used for storing device firmware, configuration parameters, and operational logs. Its wide temperature range and data stability make it particularly suitable for industrial environment requirements. In the consumer electronics sector, such as smart home devices, wearable devices, and digital products, the memory’s compact size and low power consumption make it an ideal choice.

Communication equipment is another important application area, where the MX25V2033FM1I is used for boot code storage and parameter configuration in routers, switches, base stations, and other devices. Its fast read speed (80MHz clock frequency) ensures rapid device startup and efficient operation. In automotive electronics, while the operating temperature range (-40°C to +85°C) may not fully meet the requirements of certain automotive-grade applications, it remains applicable in non-critical automotive electronic systems.

Compared to similar products on the market, the MX25V2033FM1I offers significant competitive advantages. Compared to traditional parallel NOR flash memory, its SPI interface significantly reduces the number of pins (only 8 pins), simplifying PCB design complexity and reducing system costs. Compared to NAND flash memory, NOR flash memory offers faster random read speeds and higher reliability, making it particularly suitable for storing executable code. Among SPI NOR flashes of the same capacity, the MX25V2033FM1I offers higher data transfer bandwidth with its four I/O modes and 80MHz clock frequency.
