BU9888FV-W is a serial EEPROM that uses a serial 3-line interface method. It has a 256-word × 16-bit architecture with a 4k bit serial EEPROM. It operates at a voltage range of 3.0 to 3.6V and features address auto increment at read action, write mistake prevention function, and program cycle auto delete and auto end function.
The BU9888FV-W is a high‑reliability serial EEPROM featuring a 256‑word × 16‑bit (4 kbit) architecture, operating voltage of 3.0 V to 3.6 V, and built‑in write‑mistake‑prevention functions. It offers low standby current (2.0 µA) and high endurance (up to 100 k write cycles) with data retention guaranteed for 40 years.
Electrical characteristics include typical supply voltage of 3.0‑3.6 V, standby current of 2.0 µA, write current of 3.5 mA, and read current of 2.0 mA at 3.6 V. The device is supplied in an SSOP‑B8 pin package and includes detailed timing diagrams, pin assignments, and command formats for integration into audio‑visual, office‑automation, communication, and consumer electronic equipment.
