93C76A-I/ST

Introduction

93C76A-I/ST is a memory chip produced by STMicroelectronics, a French-Italian semiconductor and microchipmanufacturer, whose products are typically used in a wide range of applications and industrial settings. The 93C76A-I/ST chip is an 8-pin non-volatile EEPROM (electrically erasable and programmable read-only memory) chip which is designed to provide a high-level of performance and reliability, and can be found in a variety of products. In this article, we will discuss the application fields and working principles of 93C76A-I/ST.

Application Fields

The 93C76A-I/ST chip is ideal for applications that require robust non-volatile memory solutions. It is particularly well-suited for consumer electronic products and embedded systems due to its small physical size, low power consumption and high level of reliability. A few examples include:

• Automobile dashboards
• Medical imaging equipment and monitoring systems
• Data loggers and remote monitoring systems
• Memory expansion boards for computers and servers
• Industrial automation and control systems
• Voice recognition and biometric products
• Wearable and device technology

The 93C76A-I/ST chip also has a wide variety of useful features which make it suitable for many other applications, including:

• 6-byte data and address buses supporting read, write and erase functions
• 256 bytes of data capacity (expandable up to 1K bytes)
• Data bus hold time of 50 ns
• 100 mA write/erase current draw
• Contains software write-protectable passwords
• Choose between two levels of programming voltage (3V and 5V)

The 93C76A-I/ST chip is a versatile and reliable memory solution which can be used in many different applications.

Working Principle

The 93C76A-I/ST chip is an 8-pin non-volatile EEPROM. It consists of four pins for power supply and I/O (Input/Output) signals and four additional pins for address and control purposes. The chip can be programmed via the I/O pins and is able to store 256 bytes of data in an 8-pin package.

For programming the 93C76A-I/ST chip, a low voltage is applied to the address bus which corresponds to the desired address of the memory cell. This address is then transferred to the internal logic circuits of the chip which select the corresponding memory cell. By setting the \“write enable\” pin HIGH, a low voltage is applied to the write data pin of the chip, which causes the contents of the memory cell to be updated with the new data.

In terms of read operations, the process is essentially reversed. The address of the desired memory cell is applied to the address bus and the \“read enable\” pin is set HIGH. This causes the desired data to be output on the read data pin of the chip. The process can be repeated for each memory cell in order to read the entire data stored in the chip.

The 93C76A-I/ST chip provides a useful and efficient way to store and load data in many applications.

Conclusion

The 93C76A-I/ST chip is a versatile and reliable non-volatile memory solution suitable for many different applications. It is typically used in consumer electronic products and embedded systems, as well as a variety of other industrial settings due to its small physical size, low power consumption and high level of reliability. The chip is programmed and read via the I/O pins, with its data is stored in an 8-pin package. The 93C76A-I/ST chip provides a useful and efficient way to store and load data.
