Additional Details:

The X28HC256KM-15 operates on a single 5V power supply. The memory array is organized as 32,768 bytes. The self-timed erase/write cycle simplifies the programming process, as external timing signals are not required. Automatic page write allows the programming of multiple bytes in a single operation, improving write throughput. The device typically comes in a DIP (Dual In-line Package) or SOIC (Small Outline Integrated Circuit) package. The X28HC256KM-15 provides a cost-effective and reliable solution for non-volatile memory requirements in a wide range of embedded systems. The device is suitable for use in applications that need to store configuration data, calibration parameters, or other critical information that must be retained even when power is removed.

Due to its high endurance and long data retention, the X28HC256KM-15 is often employed in applications where data is frequently updated or where data integrity is paramount. Its fast access time makes it suitable for systems where rapid data retrieval is crucial for performance.
