Memory is a core component of many electronic systems and devices, playing a key role in the day-to-day operation. Among them is 7034S20PF8, a 128K x 8 asynchronous static random access memory (SRAM). This article seeks to look at its application field and working principle.

7034S20PF8, manufactured by Xilinx, is an asynchronous static RAM built on a 0.35 micron CMOS process. It is a low power device and features 64 words (128 bits) by 8 bits configuration, and is a suitable choice for memory application in different fields. The most common applications are mixed signal processing, computer telephony, protocol processing, image processor, audio processor and so forth.

In mixed signal processing, 7034S20PF8 primarily functions as a data buffer to store and read input signals. Its low power consumption and small size make it an ideal choice for this application. In computer telephony, it serves as an addressable buffer, allowing users to access information stored in a memory location. In protocol processing, it is used to store information, such as address and data, so that transmission rules are matched.

In addition, 7034S20PF8 is often used for image processing and audio processing. In image processing, it stores pixel data and is used for the manipulation of image signals. In audio processing, it stores information such as sound effect parameters, enabling sound signals to be processed.

The way 7034S20PF8 works is that it transfers data between an external address bus and an internal data bus. When an address is applied to the input address port, the data stored in the corresponding address is driven out of the output data port. The input data can be written into the corresponding memory address by applying the data to the input data port and applying Write Enable signal to the WE port.

In terms of operation, 7034S20PF8 has a standby current of 4 mA, a cycle time of 55 ns and an access time of 45 ns. It works with a supply voltage between 2.7V and 3.6 V, and its operating temperature range is between 0°C and 70°C. It also has a read/write current of 0.5mA and data retention current of 1µA.

To summarise, 7034S20PF8 is a low power asynchronous static random access memory applicable for a variety of fields. It can store and process data signals, such as pixel data and sound effect parameters, and it works via an external address bus and an internal data bus. In terms of operation, it has a standby current of 4 mA, a cycle time of 55 ns, an access time of 45 ns, a supply voltage between 2.7V and 3.6 V, and an operating temperature range of 0°C to 70°C.
