The Serial EEPROM, part number 68T4072, is a 4Kbit memory device organized as 512 x 8 bits. It operates at a voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 1 MHz. The device features a two-wire serial interface, allowing for bidirectional data transfer, and includes a write protect pin for hardware data protection. It supports 16-byte page write modes and allows for partial page writes, with a self-timed write cycle of up to 5 ms. The EEPROM is designed for high reliability, offering an endurance of 1 million write cycles and a data retention period of 100 years. It is available in multiple package types, including an 8-lead TSSOP, and is compliant with lead-free and halogen-free standards. The operating temperature range is from -55¬8C to +125¬8C, making it suitable for various industrial and commercial applications.
