The 54AH6681 is a 64 Kbit (8 Kbyte) EEPROM from STMicroelectronics, designed for automotive applications. It operates over an extended temperature range of -40 ¬8C to 125 ¬8C and supports a supply voltage range of 1.7 V to 5.5 V. The device is compatible with all I¬=C bus modes, including 1 MHz, 400 kHz, and 100 kHz. It features a memory array with a page size of 32 bytes and includes an additional write-lockable identification page. The EEPROM offers a short write cycle time, with byte writes completed within 4 ms and page writes also within 4 ms. It has a write cycle endurance of up to 4 million cycles at 25 ¬8C, decreasing to 600 k cycles at 125 ¬8C. Data retention is specified for 50 years at 125 ¬8C and 100 years at 25 ¬8C. The device includes Schmitt trigger inputs for noise filtering and is RoHS compliant and halogen-free. ESD protection is rated at 4000 V according to the Human Body Model.
