93C66C-E/ST Application Field and Working Principle

93C66C-E/ST is one of the most famous memory chips among the semiconductor industry. It is widely used in many industrial applications and is popular for its non-volatile, low power consumption and robustness. This article will explain 93C66C-E/ST application field and its working principle.

Application Field

The 93C66C-E/ST has been widely used in industrial applications such as numerical analysis, data processing, data storage, system controls, and others. It is used in electronic equipment and instruments, such as medical instruments, telecommunication systems, computer systems, information systems, consumer products, embedded system, military systems, automation systems, industrial control, and so on. It is also used in microcontrollers, automotive electronic control systems, aerospace/aviation, data acquisition and control, military applications, industrial machinery and instrumentation, consumer products, and sensors.

For example, this memory chip is used in microcontrollers to store program instructions and data, in automotive electronic control systems for storing the parameters, in aerospace/aviation for data stored for the guidance, navigation and control systems, in military applications for data stored for the weapons systems, and in other industrial control applications for storing the parameters for these systems.

Working Principle

The 93C66C-E/ST is a Serial Access Memory, which reads and writes data with low power consumption and very high speed. The chip structure is divided into two types: 8K-bit and 4K-bit. The 4K-bit type is organized in 4K+64 bytes (each byte consists of 8 bits). The 8k-bit type is organized in 8K+128 bytes.

The chip consists of 8-bit data bus and 10 or 20 control pins. The read and write operations are enabled by controlling the chip by using the control pins. The chip has an internal address counter and can be used to access a specific location increases the access time. It provides a sequential read only operation with no internal address counter used.

The chip has a two-wire Serial Peripheral Interface (SPI) bus and a one-wire bus. The one-wire bus used for communication with a microcontroller or another device. The chip has an asynchronous write capability, with no programming or erasure operations, making it very suitable for applications that require fast access times.

The chip provides its own internal protection against over-voltage, short-circuits and other potential damage. It offers two levels of protection: static (default) and dynamic (optional). The static level is a simple voltage limiter, which helps to prevent the chip from being damaged by damaging the power supply. The dynamic level helps to protect the chip in case of over-voltage, excessive current, and temperature or electrical noise.

Conclusion

93C66C-E/ST is a very popular memory chip and is used in many industrial applications. It provides a fast access time, low power consumption and is robust due to its two-level protection mechanism. The chip is designed for use in microcontrollers, automotive, aerospace, military and industrial control applications. This article provides knowledge about the usage of this chip and its working principle.
