Memory

The MT45W1MW16PAFA-85 WT memory is a type of copper dual- in-line RAM technology with a reliable power up sequence. It has a large capacity of 16 megabytes, operates at a low voltage of 1.8 V and features non-volatile SRAM technology with a built-in parity function on chip. It is widely used for high performance, low power memory models, mainly in automotive, consumer, industrial and medical applications.

Applications

Due to its excellent performance, the MT45W1MW16PAFA-85 WT has been widely adopted in various industrial applications, such as remote communication, medical equipment, consumer electronics, automotive systems and industrial control systems. The use of this memory in these fields is primarily due to its features like low thermal load, low operating temperature, accurate signal timing and low ripple noise. Besides, its wide operating temperature range, from -40 to +85oC, further boosts its usage in automotive and industrial applications.

Working Principle

The working principle of MT45W1MW16PAFA-85 WT memory is essentially identical to that of other copper dual-in-line RAMs. It follows a three-step power-up sequence, where a voltage is supplied to capacitor C1 for 30ns before the VCCA voltage is supplied, followed by the supply of VCCQ voltage for 11ns. This brief flow is essential for proper power-up and prevents the device from entering an unstable state. The memory works by storing data in addressable memory cells, where each cell has a unique address. When the memory controller sends a “READ” command, the address lines select which cells should retrieve the data. The data lines then transport the contents of the cells to the data register, which then sends the data to the processor. On the other hand, when the memory controller sends a “WRITE” command, the data lines supply the data to the data register. This data is then stored in the addressable memory cell designated by the address lines.

Conclusion

The MT45W1MW16PAFA-85 WT is a reliable memory that effectively solves the energy, reliability and performance needs of those that use it in their products. Its low voltage and wide operating temperature range make it particularly suitable for automotive and industrial applications. As a result, it is extensively used in these areas and is becoming a standard option for many modern products.
