FT24C128A-USG-B is a non-volatile memory and it is widely used in numerous applications. In this article, we will discuss the application field and working principle of this product.

FT24C128A-USG-B belongs to the familly of non-volatile memories, which are non-volatile digital memories that can retain information even when power is switched off. Unlike volatile memories, non-volatile memories can maintain stored data without the need for constant power supply. This makes them ideal for applications where no continuously powered supply is available, and in some cases, where a device needs to remember information even after power is switched off.

A typical application field of FT24C128A-USG-B is in embedded systems. Embedded systems incorporate computing and control elements which interact with their environment, and in many instances require a non-volatile memory to store data in order to fulfilling their task. FT24C128A-USG-B is ideal for such applications as it is both reliable and economical.

By utilising a 3-wire Serial Peripheral Interface (SPI) bus, FT24C128A-USG-B can communicate with an external microcontroller or processor, thereby enabling data to be read and written between the two devices. Its simple communication interface allows it to connect easily to most embedded systems.

FT24C128A-USG-B has a capacity of up to 128Kbits (16KB) and can be used to store large amounts of data. It is also able to retain data even in the event of power loss, making it a reliable storage solution for embedded systems.

The working principle of FT24C128A-USG-B fits in with the conventional non-volatile memory technology. It has a memory array which is divided into a number of pages, where each page can store up to 256 bytes of data. The data can be written or read from the memory array by the SPI bus, which enables communication between the FT24C128A-USG-B and an external system.

To write data to the FT24C128A-USG-B, the external system sends a write command to it, followed by the page address, the data to be written and a verification code. Upon receiving the write command, the FT24C128A-USG-B temporarily sets its write enable latch, which causes the memory array to accept data. The data is then written to the addressed page in the memory array. The external system then sends a verification codes in order to verify that the data was written correctly. The FT24C128A-USG-B then sets its write disable latch which stops the memory array from accepting more data.

To read data from the FT24C128A-USG-B, an external system sends a read command to it, along with the page address of the data that it wishes to read. Upon receiving the read command, the FT24C128A-USG-B sets its read enable latch, which allows the content of the addressed page to be transferred to the external system.

In summary, FT24C128A-USG-B is a non-volatile memory which is widely used in embedded systems due to its reliability and cost-effectiveness. It is able to store up to 128Kbits of data, and this data can be written to and read from its memory array using a 3-wire SPI bus.
