The D2817A-3 is an EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Intel. EEPROMs are a type of non-volatile memory that can be electrically erased and reprogrammed. Although specific details on the D2817A-3 are limited, its general purpose is data storage in applications requiring occasional updates.

Applications

• Embedded Systems: Storing configuration settings, calibration data, and other non-volatile data in embedded systems.
• Industrial Control Systems: Used in programmable logic controllers (PLCs) for storing program parameters and settings.
• Data Acquisition Systems: Storing calibration data and sensor readings in data loggers and other data acquisition devices.
• Smart Cards: Used for storing personal and financial information in smart cards.
• Electronic Instruments: Storing instrument settings and calibration data in electronic test equipment.

Features

• Electrically Erasable and Reprogrammable: Can be erased and reprogrammed electrically, eliminating the need for UV light.
• Non-Volatile Storage: Retains data even when power is removed.
• Fast Write Times: Offers relatively fast write times compared to other non-volatile memory technologies.
• High Endurance: Can withstand a large number of erase/write cycles.
• Low Power Consumption: Consumes relatively low power during read and write operations.

Benefits

• In-System Reprogramming: Allows for easy updating of data without removing the chip from the circuit.
• Reliable Data Storage: Provides a stable and secure storage solution for critical data.
• Reduced Development Time: Simplifies the process of updating and modifying stored data.
• Long-Term Data Retention: Ensures data is retained for extended periods without degradation.
• Versatile Application: Suitable for a wide range of applications requiring non-volatile memory.

Additional Details

While precise specifications for the D2817A-3 necessitate further research, key parameters usually include supply voltage (e.g., 5V), access time (speed at which data can be read, e.g., 150ns or higher – the “-3” may relate to speed grade), and endurance (number of erase/write cycles the memory can handle, typically in the thousands or hundreds of thousands). The packaging is [Search to confirm specific package type, e.g., DIP or SOIC]. Temperature ratings also vary, with industrial temperature ranges (e.g., -40°C to +85°C) being common. Further investigation is needed to determine the exact specifications.
