BR93H46RFJ-2C is a 1KBit serial EEPROM designed for automotive applications, operating within a wide temperature range of -40¬8C to +125¬8C. It utilizes a 3-wire Microwire BUS interface and supports a supply voltage range of 2.5V to 5.5V. The device features write protection mechanisms to prevent accidental data corruption, including write prohibition at power-on and through command codes, as well as a low voltage write mistake prevention circuit. The EEPROM offers a self-timed programming cycle and indicates its status with a READY/BUSY output. It has a low supply current consumption, with typical values of 0.8mA for write operations and 0.5mA for read operations at 5V. The device is housed in compact packages such as MSOP8, TSSOP-B8, SOP8, and SOP-J8, making it suitable for space-constrained applications. It is AEC-Q100 qualified, ensuring reliability for automotive use, with a data retention period exceeding 50 years at 125¬8C and a write endurance of over 300,000 cycles at the same temperature.
