The AT28C64X-25JI is a type of memory. It is a 64K electrically erasable programmable read-only memory (EEPROM). An EEPROM is unlike a regular read-only memory in that it can be erased and reprogrammed repeatedly. This makes it extremely useful in many applications.

The AT28C64X-25JI is a popular choice for applications including data storage, firmware storage and boot code storage. It can also be used as a multiplexer-selector, latch and signal storage device. It has been used as form of non-volatile storage in many embedded systems. Some common applications include automotive electronics, industrial automation systems, control systems, and medical devices.

The AT28C64X-25JI is based on the original AT28C64X architecture. It has an 8 Kbit array organization of 8 K bits x 128 bytes. It also features an address counter and control logic which facilitates programming. The EEPROM is organized as 8K words of 8bits and is capable of being erased and reprogrammed in one byte increments.

The AT28C64X-25JI works by applying an electric current through two transistors in the same row. This generates a voltage across the two transistors which relays data between the row of transistors and the adjacent rows. Through iterative application of this current, the memory can be erased, programmed or read.

In order to reduce pin count and power usage, the AT28C64X-25JI also has a proprietary energy-saving mode which reduces current consumption from 2.75 mA to 90 μA. This makes it an ideal choice for applications which require lower power consumption or battery-powered solutions.

In terms of security, the AT28C64X-25JI also features an advanced protection feature which prevents accidental re-writing of the EEPROM data. This makes it ideal for applications which require secure data storage and transmission.

The AT28C64X-25JI is a versatile memory device which is well-suited to many industrial and consumer applications. It is designed to be low-cost, low-power and secure yet highly reliable. Its many features make it an ideal choice for applications where performance, reliability and cost are important factors.
