Application Field of the AT28C17E-15JI

The AT28C17E-15JI is used in a wide range of digital systems, including embedded control, automotive, consumer and digital consumer electronics, medical, industrial, and telecommunications. It can be used in a wide range of application areas, such as telephone switching, alarm systems, home and automotive electronics, programmable logic circuits, audio circuits, and data storage. Its wide range of applications makes the AT28C17E-15JI an ideal solution for a variety of digital systems.

Working Principle of the AT28C17E-15JI

The AT28C17E-15JI uses a Schmitt Trigger input for read and write operations. This is typically used for applications that require low power or very low power operation. When a read or write operation is performed, the device will determine the state of the Schmitt Trigger input and either read or write the data to the ROM. Once the data has been written, the device will then latch it in internal memory, allowing it to be retrieved at any time. The AT28C17E-15JI also incorporates a self-timed programming feature, which reduces average programming time and eliminates unnecessary waiting.

The AT28C17E-15JI also has two different types of access modes: “by data” and “by address”. In “by data” mode, the data is read or written directly from the serial or parallel port, with the specified read or write address. In “by address” mode, the data is read from or written to the device address register, with the specified data. The address register is first loaded with the address, and then the data is read or written.

The AT28C17E-15JI also features a power-down feature, which reduces average power consumption by up to 90%. This is achieved by disabling the internal registers when the device is not in use, thus ensuring the device operates at its optimum power efficiency.

Conclusion

The AT28C17E-15JI has a wide range of applications, including embedded control, automotive, consumer and digital consumer electronics, medical, industrial, and telecommunications. It is a low power, high performance device that is ideal for applications that require low power or very low power operation, such as telephone switching, alarm systems, home and automotive electronics, programmable logic circuits, audio circuits, and data storage. The AT28C17E-15JI also has two different types of access modes, “by data” and “by address”, as well as a power-down feature to reduce average power consumption. It is an ideal solution for a variety of digital systems.
