The CAT28LV65J-15 is a low voltage non-volatile EEPROM memory chip manufactured by Catalyst Semiconductor. It is a parallel architecture mounted on a surface mount package, which is a SO28 case in size. It is rated to operate at a voltage range of 3 to 3.6 volts, and has a temperature range of 0 degree to 70 degrees Celsius. It has a total capacity of 65 Kbit (8K x 8). This EEPROM memory includes an I/O cell as well as an I/O protection circuit, a Sleep mode, an Advanced Auto-Write FIFO, and an Enhanced-Latch-Up proofing. It also has write protect and device protect features. This device is suitable for use in data storage applications from 8 bit to 32 bit microcontroller applications.
