MX29LV400CBMC-55Q

Memory products are ranked among the most important electronic components. Among all kinds of memory technologies, Flash memory is a widely used kind of non-volatile memory. The MX29LV400CBMC-55Q, which is manufactured by Macronix, is a long-term product line, and is one of the most cost-effective options. It is widely used in many industries, particularly in consumer electronics applications.

Application Field

The MX29LV400CBMC-55Q is one of the most widely used Flash memory devices. It is a 4M x 8 bit CMOS multi-level-cell (MLC) NAND Flash memory product, which makes it suitable for a variety of applications. It is primarily used in embedded systems and consumer electronics products, such as portable media players, digital cameras, mobile phones, and digital video recorders. It has a wide operating temperature range of -40°C to 85°C and is also externally tested with over 15 varieties of product validation, which makes it suitable for automotive and industrial applications.

It is highly suitable for applications that require greater capacity and better performance than conventional a Single-Level-Cell (SLC) NAND Flash. It has low power-consumption, small form factor and high write endurance, which makes it suitable for system applications that require small form factor, high-density NAND Flash.

Working Principle

The MX29LV400CBMC 55Q consists of 4Mx8 bits CMOS memory array, consisting of 32Kx128 words (4096 pages). Each page is 512 bytes and a single-level cell (SLC) scheme is utilized. This scheme is composed of 16 bits per cell, and two bits are used as status and 54 bits serve as memory data. The device is compliant to the JEDEC Single-Level-Cell (SLC) standards.

The main function of the device is to read and write data. Internally, it is based on Reliability Protocol called “Write Endurance Control,” which is comprised of periodically re-writing data within the flash array. This protocol controls the write endurance of the MLC NAND Flash array, thus keeping the data retention properties and endurance at an acceptable level. For example, when writing data, the controller needs to re-write data periodically to prevent retention issues.

The device also has an array of power management features such as standby/active power modes. In the standby mode, the device takes up 6.5uA, which is drastically lower than the active mode, making it suitable for power-conscious applications. Additionally, the device stands out in its part-die feature, which is useful in consumer-electronic applications.

Conclusion

The MX29LV400CBMC-55Q is a mid-sized, cost-effective Flash memory device manufactured by Macronix. It is used in many consumer electronics, embedded systems and automotive applications. It works on the single-level cell (SLC) scheme and has a low power-consumption and high write endurance. The overall advantage of this device is its compatibility with a wide range of applications and its performance in both active and standby state.
