The voltage range is from 2.5V to 3.6V, which is suitable for industrial, commercial and automotive applications. The device is available in several packages, including QFP, TQFP, and TSOP-II.

The CAS24S128C4ATR is designed to be used in a variety of applications, from industrial control systems to automotive infotainment systems. Its 16-bit data bus and multiplexed address bus makes it ideal for high-speed data storage and retrieval applications. The CAS24S128C4ATR provides a fast write access time of 17 nanoseconds, allowing for quick and efficient data storage. The device features a low voltage operation (2.5V-3.6V) and a low power consumption of 90mW, making it an ideal device for industrial, commercial and automotive applications.

The working principle of CAS24S128C4ATR is based on CMOS logic. It is composed of four cells. The memory address lines (A0-A15) are multiplexed into address/data inputs in such a way that one set of data leads can access both the QD and QN inputs of the memory. The QD input stores the data in the cell while the QN input is used to read the data from the cell. Each cell contains four transistors, two of them are connected to the QD and QN inputs and the other two are connected to ground (VSS) and power (VCC). When a voltage is applied to the clock (CLK) input, the corresponding data is loaded into the cell. When a voltage is applied to the enable (E) line, the data is read from the cell.

To sum up, the CAS24S128C4ATR is a 64K-bit SRAM chip designed for use in industrial, commercial and automotive applications. It features a multiplexed address/data input of 16 bits, fast write access times (17ns), read access times (8ns) and low power consumption (90mW). It also has an operational voltage range of 2.5V to 3.6V. The CAS24S128C4ATR is an ideal device for applications requiring fast data storage and retrieval.
