Microchip Technology AT28C64X-25PI EEPROM

The AT28C64X-25PI is a high-performance Electrically Erasable Programmable Read-Only Memory (EEPROM) integrated circuit produced by Microchip Technology. This device is designed for applications requiring data storage that can be modified in the field, offering a flexible and reliable solution for a wide range of industries including telecommunications, automotive, industrial control systems, and consumer electronics.

The AT28C64X-25PI boasts a 64-kilobit memory capacity, allowing for the storage of 64K (8,192 x 8) bits of data. This memory is organized as 8,192 words of 8 bits each, providing ample space for firmware storage, configuration parameters, or any other data that needs to be preserved between power cycles.

This particular model, with a 25-nanosecond access time, is tailored for high-speed operation, enabling quick data retrieval and enhancing the performance of the overall system. The fast access time is particularly beneficial in applications where speed is critical, such as real-time computing environments.

The EEPROM is housed in a robust 28-pin plastic DIP (Dual In-line Package), making it suitable for through-hole mounting on printed circuit boards. The AT28C64X-25PI operates over an industrial temperature range, which ensures reliable performance even in extreme conditions.

Microchip's AT28C64X-25PI is designed with ease of use in mind, featuring a simple parallel interface for communication with microcontrollers or microprocessors. It requires a single 5V power supply for operation, which simplifies power management in embedded systems. Additionally, the EEPROM supports 100,000 write/erase cycles and has a data retention of 10 years, guaranteeing long-term reliability for applications that require frequent data updates.

The device also includes safety features such as hardware data protection during power-up, power-down sequences, and a software data protection scheme to prevent inadvertent writes, thus ensuring the integrity of the stored data.

Overall, the AT28C64X-25PI from Microchip Technology is a versatile and reliable EEPROM solution that offers a combination of speed, durability, and ease of integration, making it an excellent choice for designers looking to incorporate non-volatile memory into their systems.
