BR93H66RFVT-2C is a 4Kbit (256x16bit) serial EEPROM that operates on a Microwire BUS interface. It is designed for automotive applications, with a wide operating temperature range of -40,ÑÉ to +125,ÑÉ and a supply voltage range of 2.5V to 5.5V. The device features a write cycle endurance of over 300,000 cycles at 125,ÑÉ and data retention exceeding 50 years at the same temperature. It includes built-in write protection mechanisms to prevent accidental data corruption, such as write prohibition at power-on and via command codes. The EEPROM also supports an address auto-increment function during read operations and has low power consumption, with typical write and read currents of 0.8mA and 0.5mA, respectively. The product is available in multiple compact package options, including MSOP8, TSSOP-B8, SOP8, and SOP-J8, and is AEC-Q100 qualified for automotive reliability standards.
