The BR24L08 is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Rohm Semiconductor. It is an 8Kbit (1024 x 8) memory device accessed via a two-wire serial interface (I2C), making it suitable for storing small amounts of configuration data, settings, or other non-volatile information in various electronic systems.
Applications:
- Storing configuration data in electronic devices: Used to save settings, calibration parameters, and other device-specific information.
- Storing user preferences in consumer electronics: Retains user-defined settings in TVs, audio equipment, and other devices.
- Storing sensor calibration data: Saves calibration values for sensors in industrial and automotive applications.
- Storing identification information: Used to store serial numbers, MAC addresses, or other unique identifiers.
- Storing system logs: Retains small amounts of system event data for debugging and diagnostics.
Features:
- 8Kbit (1024 x 8) EEPROM: Provides non-volatile storage for small amounts of data.
- Two-Wire Serial Interface (I2C): Simplifies communication with microcontrollers and other devices.
- Low Voltage Operation: Operates from a low voltage supply, suitable for battery-powered applications.
- Write Protect Feature: Prevents accidental data modification.
- Self-Timed Write Cycle: Simplifies the write process and reduces the need for external timing components.
- High Reliability: Offers high endurance and data retention.
Benefits:
- Non-Volatile Storage: Retains data even when power is removed.
- Easy to Use: I2C interface simplifies integration into various systems.
- Small Size: Compact package saves board space.
- Low Power Consumption: Suitable for battery-powered applications.
- Reliable Data Storage: Ensures data integrity over a long period.
Additional Details:
The BR24L08 is typically available in small surface-mount packages, such as SOIC and TSSOP. It requires a pull-up resistor on the I2C data and clock lines. Detailed specifications, including voltage range, operating temperature, and timing characteristics, can be found in the product datasheet from Rohm Semiconductor. Programming and reading from the EEPROM are typically performed using standard I2C communication protocols.
