BU9883FV-W is a plug and play I2C BUS 3-port serial EEPROM for DDC 3 ports, with multiple features and characteristics.

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.

BU9889GUL-W is a serial EEPROM with I2C BUS interface. It completely conforms to the world standard I2C BUS and can be controlled by two ports of serial clock (SCL) and serial data (SDA). It has a 1k words×8 bits architecture, suitable for 8kbit serial EEPROM. Other devices than EEPROM can be connected to the same port, saving microcontroller port. It is a single power source with an action range of 1.7~5.5V, most suitable for battery use. It operates at FAST MODE with a speed of 400kHz at 1.7~5.5V. The page write mode is useful for initial value write at factory shipment. It has auto erase and auto end function at data rewrite. The current consumption is low, with 0.5mA (Typ.) at write operation, 0.2mA (Typ.) at read operation, and 0.1µA (Typ.) at standby operation, all at 5V. It has a write mistake prevention function and write (write protect) function added at low voltage. It comes in a WLCSP6pin compact package. The data can be rewritten up to 100,000 times and kept for 40 years. It has a noise filter built in SCL / SDA terminal. The shipment data has all address FFh.

BU9891GUL-W is a serial EEPROM with a serial 3-line interface method. It can operate at a high speed of 2MHz clock (2.5~5.5V), has fast write (write time max. 5ms), single power source operation of 1.7~5.5V, auto address increment function at read operation, write error prevention function, write prohibition at power on, write prohibition by command code, write error prevention function at low voltage, program cycle auto delete and auto end function, READY/BUSY display of program condition and low current consumption

BU9897GUL-W is a 128Kbit I2C BUS interface serial EEPROM produced by ROHM. It has the characteristics of low power consumption, high withstand voltage, 400kHZ high-speed communication, automatic erasure and automatic end function.

The BU99901GUZ-W series is a serial EEPROM of I2C BUS interface method.

This document describes the features and characteristics of the BR24T series high reliability serial EEPROMs, including compliance with the world standard I2C BUS interface, the ability to connect other devices to the same port, single power source operation suitable for battery use, wide operating voltage range, fast mode 400KHz operation, page write mode, auto erase and auto end function, low current consumption, write mistake prevention function, various packaging options, data rewrite up to 1,000,000 times, and data retention for 40 years.

The BR25Hxxx-WC series is a serial EEPROM with a SPI BUS interface method.

BU2280FV, BU2360FV, BU2362FV are ROHM company's high-performance clock generators that integrate the 3 clock signals required for DVD players, namely VIDEO, AUDIO, and SYSTEM clocks, using PLL technology. The AUDIO clock is a DVD-Video standard and has high C/N characteristics that lower distortion.

BU2285FV,BU2363FV are high-performance clock generators produced by ROHM. They can generate VIDEO, AUDIO and SYSTEM clock signals for DVD player systems. Among them, the VIDEO clock is a DVD audio reference clock with high C/N characteristics, which can provide high-definition images.

This document introduces ROHM's high-performance clock generator series, which is used to generate high-frequency CCD, USB, and video clocks in digital cameras and digital video cameras. The products feature compact packaging, selectable frequencies, low jitter, and high precision.

ROHM's BD45xxx and BD46xxx series are highly accurate, low current consumption reset IC series. Because the counter timer delay circuit is built into those series, an external capacitor for the delay time setting is unnecessary. The lineup was established with tow output types (Nch open drain and CMOS output) and detection voltages range from 2.3V to 4.8V in increments of 0.1V, so that the series may be selected according the application at hand.

The BD47xx series is a reset IC that was developed to prevent system errors at transient state when the power of CPU or logic circuit switches ON/OFF or momentary shut down.
