ROHM Semiconductor USA, LLC Memory BR93G66F-3AGTE2

The BR93G66F-3AGTE2 is a 4Kbit serial EEPROM from Quarktwin Technology Ltd., utilizing a MicroWire 3-wire interface for communication. It supports dual organization modes, allowing data to be accessed in either 16-bit or 8-bit formats, selectable via the ORG pin. The device operates at a supply voltage range of 1.7V to 5.5V and can achieve high-speed operations with a clock frequency of up to 3MHz. Key features include a maximum write time of 5ms, an address auto-increment function during read operations, and multiple write protection mechanisms to prevent errors, including write prohibition at power-on and low voltage conditions. The BR93G66F-3AGTE2 is designed for longevity, offering over 40 years of data retention and more than 1 million write cycles. It is available in various compact package options, including SOP8 and TSSOP-B8, making it suitable for space-constrained applications.
