The CAT28C64BT13I-15T is a non-volatile, electrically programmable and erasable read-only memory (EEPROM) integrated circuit manufactured by Catalyst Semiconductor Inc. It features 8Kbit of memory size and comes in a 28 pin TSSOP (Thin Shrink Small Outline Package) case with a Smd (Surface Mounted Device) mounting type. The operating temperature range for this device is -40°C to +85°C and it is rated for a voltage of 5V. It has a parallel access memory with the 2-Wire Serial EEPROM Bus protocol providing fast and easy access to microcontrollers. Furthermore, the circuit provides improved device reliability and enhanced endurance up to 10,000 write cycles and also includes a low power stand by mode. This device is ideal for applications such as consumer electronics, industrial automation and medical devices.
