Memory technology is widely used in a variety of applications and the STK12C68-SF25TR is no exception. The STK12C68-SF25TR is a suitable type of memory for a range of applications. This article will provide a summary of the application field and working principle of the STK12C68-SF25TR.

STK12C68-SF25TR is an intergrated 3V 128Kbit (32KByte) static RAM. It feature fast random cycle times, low power dissipation, and auto power down modes. Due to its high speed and low power requirement, the STK12C68-SF25TR is a preferred type of memory for many types of applications.

The application field of the STK12C68-SF25TR includes that of personal digital assistants (PDAs), cellular phones, laptop computers, and musical instruments. With the exception of musical instruments, where the primary purpose is to store sound data, a key feature of the STK12C68-SF25TR is that is to provide memory for data exchange or to support the software function of the device. For example, a laptop may use the STK12C68-SF25TR to store software programs that makes it easier to use, while a PDA may use it to store address book information.

The technical data of the STK12C68-SF25TR corresponds with the various types of applications for which it can be used. The device is composed of a single chip microcontroller with maximum addressing capability of 4Mbits (8MBytes). It supports a variety of access cycle times, including the access times of 70, 150 and 190ns. The STK12C68-SF25TR also allows power down modes which reduce the power dissipation to less than 1mW while the device is in standby mode.

To understand the working principle of the STK12C68-SF25TR, we must first consider how memory is organized. Memory is usually divided into individually addressable storage locations, also known as cells. In the case of the STK12C68-SF25TR, each cell is capable of storing 8 bits (1 byte) of information. Additionally, the cells are organized in a series of blocks, or rows and columns, forming the overall memory map of the device. For example, the STK12C68-SF25TR has a map of 32KByte, with 32 rows and 1,024 columns.

The information in a memory cell is read into a register of the micro-controller, and the data is written to the register from the cell. This process is known as reading or writing of data. The STK12C68-SF25TR can support up the four different read/write operations: sequential read, burst read, random read, and write. Sequential read and burst read are both performed once a single address is read into the register, while random read is performed by providing the next cell address. Lastly, write operations are much more complicated and involve more than one cycle.

Overall, the STK12C68-SF25TR is suitable for a variety of applications such as personal digital assistants and laptop computers. Its technical data and range of access times meet the requirements of theses applications, while its low power consumption makes it a preferred choice of memory. Furthermore, its working principle is based on the concept of individual addressable cells and the various types of read and write operations that the device can support.
