IDT71V124SA20PHI

Introduction

The IDT71V124SA20PHI is a type of 1K x 24 CMOS Static RAMs (SRAMs) designed for general purpose, high density memory applications. It offers a fast access time of 20ns and a low power consumption of 3.2 mW. Furthermore, this module provides single power supply and one-time programming to optimize its performance. This module is also ideal for applications that require a high-response rate and large memory capacity.

Application Field

The IDT71V124SA20PHI is mainly used in embedded systems such as communication systems and multimedia systems, as well as for memory mapping for an embedded processor. Memory mapping allows the processor to access memory-mapped I/O devices, as if they were RAMs. This reduces the amount of control lines needed to read or write to the memory-mapped device. Moreover, the SRAMs can be used for buffering between the CPU and external devices, as well as for data and address latency.

Thanks to its high-speed access time of 20ns and low-power consumption, the IDT71V124SA20PHI can also be used in applications such as digital signal processing (DSP), data logging and occasional need for fast access.

Working Principle

The IDT71V124SA20PHI is a type of SRAM. SRAMs are a type of memory chip which stores each bit of data as a binary “1” or “0”, while other types of memories such as random access memories (RAMs) store bits of data as electrical charges. The IDT71V124SA20PHI works by storing two states of charge contrastingly, denoting a “1” and a “0” in its memory cells.

Its cells are arranged in a grid pattern and are connected to two horizontal and two vertical lines. When a voltage is applied to one of the vertical lines, then all cells connected to that line change their charge state. It is then possible to read the cells’ state by applying a voltage to the other two lines and then measuring the charge of the working cell.

In order to program the device, a voltage is applied to the two individual control lines, which then causes the working cell to change its state, thus creating a binary word. In order to read the content of the memory device, one must apply an appropriate voltage to a T (transfer) pin.

Conclusion

To sum up, the IDT71V124SA20PHI is a high-performance static RAM module with a fast access time of 20 ns and a low power consumption of 3.2 mW. Due to its characteristics, it is mainly used in various embedded systems such as communication systems and multimedia systems, as well as for memory mapping for an embedded processor. It also has several other applications such as digital signal processing, data logging and occasional need for fast access.
