The BR93A76RFVM-WM is an 8Kbit serial EEPROM designed for automotive applications, capable of operating in a temperature range from -40¬8C to +105¬8C. It utilizes a 3-wire MicroWire bus interface for communication, supporting high-speed operations with a clock frequency of up to 2MHz. The device features a fast write time of 5ms maximum and includes several protective functions such as write prohibition at power-on and by command code, as well as a write mistake prevention function at low voltage. This EEPROM operates with a single power supply voltage between 2.5V and 5.5V and has low current consumption, with typical values of 1.2mA during write operations and 0.3mA during read operations at 5V. It also boasts a data retention period of 40 years at 25¬8C and an endurance of up to 1,000,000 write cycles. The BR93A76RFVM-WM is AEC-Q100 qualified, ensuring its reliability for automotive applications. The device is available in various package types, including SOP8, SOP-J8, TSSOP-B8, and MSOP8, maintaining the same pin layout across different memory capacities.
A serial EEPROM(Electrically Erasable Programmable Read Only Memory) is non-volatile memory that can be overwritten electrically, in units of bytes, and is most suitable for data storage use. ROHM's high reliability serial EEPROMs are among the top of their class. They command a large market share and are available in a range of capacities, bus interfaces (Microwire, I²C, SPI), operating voltages (1.8V to 5.5V, 2.5V to 5.5V) and package types, making them ideal for battery powered devices. The entire series are both lead-free and RoHS-compliant.
