BU9832GUL-W is an 8Kbit serial EEPROM utilizing an SPI bus interface, designed for low power consumption and suitable for battery-operated applications. It operates with a single power supply voltage ranging from 1.8V to 5.5V and supports high-speed clock operation up to 5MHz. The device features a page write mode, allowing for efficient initial value writing, and includes a wait function via the HOLD terminal. The EEPROM supports data retention for up to 40 years and can endure up to 1,000,000 write cycles. It incorporates several write protection mechanisms, including write prohibition at power-on, command code restrictions, and a write protection pin. The compact VCSP50L2 package measures 2.09mm x 1.85mm x 0.55mm, making it suitable for space-constrained designs. Typical current consumption is 1.5mA during write operations and 1.0mA during read operations, with a standby current of just 0.1µA.
New package type, which is WL-CSP, is lined up to the high-reliability EEPROMs. There are a variety of interface products available such as I²C BUS and SPI BUS for the small application (i.e. wireless LAN, Blue tooth, and so on).
