Microchip Technology's AT28C64-15SI EEPROM

The AT28C64-15SI is a high-performance Electrically Erasable Programmable Read-Only Memory (EEPROM) integrated circuit produced by Microchip Technology. This device offers a versatile storage solution for a wide array of electronic applications, including computing systems, industrial controls, and consumer electronics that require reliable non-volatile memory.

With a 64K (8,192 x 8) memory configuration, the AT28C64-15SI provides ample space for firmware storage, configuration parameters, or any data that must be preserved across power cycles. The '-15' in the part number indicates a fast access time of 150 nanoseconds, making this EEPROM suitable for high-speed microprocessor systems.

One of the key features of the AT28C64-15SI is its simple and efficient parallel interface, which allows for easy integration into a variety of bus-oriented systems. The device supports a wide operating voltage range, typically from 4.5V to 5.5V, which is compatible with standard 5V digital logic levels.

The AT28C64-15SI is designed with longevity and data retention in mind, boasting a data retention period of at least 10 years and endurance of 100,000 write cycles per byte, ensuring the reliability of the data stored within. Additionally, the EEPROM supports full static operation, meaning no clock or refreshing is required.

For added convenience, the AT28C64-15SI includes hardware data protection features. The device's programming is performed one byte at a time, and once programmed, the data becomes non-volatile and is protected against inadvertent erasure or alteration. The chip is packaged in a standard 28-lead SOIC, providing a compact footprint that is ideal for space-constrained applications.

Overall, the AT28C64-15SI from Microchip Technology is a robust and reliable EEPROM solution that offers quick access times, easy integration, and secure data storage, making it an excellent choice for designers looking to incorporate non-volatile memory into their systems.
