The BR25L160FVT-F2 is a 16Kb serial EEPROM manufactured by Rohm Semiconductor. This is a non-volatile memory device, meaning that it retains its data even when power is removed. It uses the SPI (Serial Peripheral Interface) protocol for communication, allowing for easy integration with microcontrollers and other digital systems.

Applications:

• Storing configuration data in various electronic devices.
• Storing user preferences in consumer electronics.
• Data logging in industrial applications.
• Storing calibration parameters in sensors and instruments.
• Replacing mechanical switches and potentiometers.

Features:

• 16Kb (2048 x 8 bits) memory capacity.
• SPI (Serial Peripheral Interface) for communication.
• Wide operating voltage range: 1.6V to 5.5V.
• Low current consumption.
• Write protect feature to prevent accidental data overwrites.
• Self-timed programming cycle.
• High reliability and data retention.
• Small VSON package.

Benefits:

• Easy interface to microcontrollers through SPI.
• Non-volatile storage ensures data is retained when power is off.
• Low power consumption makes it suitable for battery-powered devices.
• Write protection prevents accidental data loss.
• Small package saves space on the PCB.
• High reliability ensures data integrity.

Additional Details:

The BR25L160FVT-F2 has an operating temperature range of -40°C to +85°C. It supports SPI modes 0 and 3. The endurance is rated for 1 million write cycles per bit. Data retention is guaranteed for 100 years. The write cycle time is typically 5ms. The VSON package is a very small outline no-leads package, designed for space-constrained applications. The SPI communication utilizes four pins: Serial Clock (SCK), Master Out Slave In (MOSI), Master In Slave Out (MISO), and Chip Select (/CS). The device is commonly used in applications requiring infrequent writes and long-term data storage.
