The AT28C64B-15JC is a type of non-volatile NVRAM chip designed to provide reliable and efficient data storage for a wide range of systems. As a form of memory, the AT28C64B-15JC uses a volatile form of static RAM (SRAM) for its primary storage. This SRAM is then augmented with an embedded non-volatile EEPROM (electrically erasable programmable read-only memory) system, allowing it to retain stored data even when the system is powered down.

The availability of this technology makes the AT28C64B-15JC an ideal solution for a range of applications, from data logging to machine control. Being non-volatile, it can be used as a storage interlock in systems where data needs to be stored when the system is powered down.

In terms of its operating principle, the AT28C64B-15JC is designed to store 8-bit words of data in an 8K-bit memory array. This array is organized as eight rows of 1,024 word locations, which can each store an 8-bit word of data. When data is written to the memory array, the memory is copied from the SRAM to an EEPROM, allowing it to be retained even when the system is powered down. The EEPROM can then be used to write and store new data, as well as overwrite existing data.

The AT28C64B-15JC is a versatile and reliable form of memory, allowing data to be stored with confidence and retrieved quickly when required. It is a popular choice for embedded data logging systems, machine control and similar applications. The ability to retain data even when the system is powered down makes it an ideal solution for time-critical applications where data needs to be retained even after an interruption to the power supply.

For those looking for a reliable, non-volatile form of memory that can retain data even after a power interruption, the AT28C64B-15JC is an ideal choice. It offers a quick and efficient way of storing and retrieving data and is suitable for a variety of applications, including embedded data logging and machine control.
