This is a 32-pin, small outline, plastic leaded chip carrier (PLCC32) type of EEPROM memory integrated circuit (IC) manufactured by Catalyst Semiconductor Inc. It has an operating temperature range from -40 to 85 degrees Celsius and uses parallel connectivity. The IC's designation is CAT28LV64GI-15, and it is mounted with a surface mounting device (SMD). It has 64K bits of EEPROM memory which is organized into 8K x 8 bits. This EEPROM memory is a non-volatile memory which retains its data storage when the power is turned off. It is capable of reading, erasing, and rewriting data at high speeds. It is commonly used in consumer electronics and other applications where non-volatile memory is important.
