Introduction

The MT28EW512ABA1HPC-1SIT (hereafter referred to as the MT28) is a serial NOR flash memory device that is built for storing and accessing data. It is ideally suited for industrial automation, IoT, consumer, automotive, and other high-performance applications with its low power requirements and small physical package size. The MT28 is based on NOR Flash technology, which is well-suited for high-speed reliable data access and continuous read operations. This article will provide insight into the field of application, features, and working principle of the MT28.

Application Field

The MT28 is a versatile and high-performance NOR Flash device that is suitable for a wide range of applications. It is designed with a wide operating temperature range of -55 ºC to 125 ºC and high storage endurance (up to 10 million cycles). This makes it an ideal choice for applications in industrial automation, consumer devices, automotive applications, and more.In industrial applications, the MT28 is ideal for storing program code, parameter data, and diagnostic information. Its low power requirements and high speed make it suitable for real-time control applications. In consumer applications, the MT28 is well-suited for data storage, multimedia playback, gaming platforms, and other applications that require low power and high speed. In automotive applications, the MT28 is an ideal choice for storing critical component information such as vehicle identification number and other key parameters.

Features

The MT28 is a wide-voltage single-supply NOR flash memory device with a small package size. With its industry-standard pin-out and high-speed timing interface, it is suitable for a wide range of applications. It has a maximum read performance of 83 MB/s, a maximum write performance of 33 MB/s, and a maximum erase performance of 600 µs for a 4K Sector. The MT28 is available in a 16-pin TSOP package with memory sizes of 512Kb, 1Mb, 2Mb, and 4Mb.The MT28 features low-power operation with standby current of 0.15µA at 2.7V. It also features-on-demand erase, program, and read functions, with larger page sizes of up to 32 bytes per page. It is ECC protected up to 6 bits per word and supports full gobal block and sector protection. In addition, the MT28 features hardware-based authentication to authenticate a controlled sector.

Working Principle

At the core of NOR Flash memory is a set of floating-gate transistors that store data when the power is off. Each bit of data is stored in a floating-gate transistor, which consists of an insulated gate connected to a source, drain, and control gate. The state of the transistor is determined by the voltage on the control gate. If the voltage is high, the transistor is "on" and the bit is stored as a "1"; if the voltage is low, the transistor is "off" and the bit is stored as a "0".The MT28 uses an advanced NOR Flash architecture that enables faster and reliable access of data. It consists of an array of memory cells arranged in blocks, which are further organized into planes. Data is written to and read from the MT28 with page-level programming, and erased by either block-level or sector-level commands. The MT28 supports two kinds of program operations: Page Programming and Word Programming. In Page Programming, multiple bytes can be programmed together, while in Word Programming only one byte can be programmed at a time. The MT28 also supports multi-plane erase, which increases erase speeds by erasing multiple planes in parallel.

Conclusion

The MT28 is a high-performance NOR Flash memory device that is ideal for industrial automation, consumer, automotive, and other demanding applications. It features low power requirements with industry-standard pin-out and high-speed read and write performance. It is ECC protected up to 6 bits per word and features hardware-based authentication to authenticate a controlled sector. Working on the floating-gate transistor architecture, the MT28 offers reliable and fast access of data with page-level programming, and block-level and sector-level erase operations.
