The BR93L46RF-W is a 4Kbit (512 x 8) serial EEPROM (Electrically Erasable Programmable Read-Only Memory) from Rohm Semiconductor. It is designed for non-volatile data storage in a variety of applications, communicating via a Microwire serial interface.

Applications:

• Consumer Electronics (e.g., TVs, Audio equipment)
• Automotive Electronics
• Industrial Control Systems
• Medical Devices
• Metering Devices
• Any application requiring non-volatile storage of small amounts of data

Features:

• Microwire Serial Interface
• 4Kbit (512 x 8) Memory Organization
• Low Voltage Operation (Typically 1.8V to 5.5V)
• Write Protect Feature (Hardware Protection)
• Self-Timed Write Cycle
• High Reliability and Data Retention
• Compact Package (e.g., SOP8)

Benefits:

• Simple Interface with Microcontrollers
• Non-Volatile Storage of Data
• Protection Against Unintentional Overwrites
• Space-Saving Design
• Cost-Effective Memory Solution

Additional Details:

The BR93L46RF-W utilizes the Microwire serial interface, which allows for easy communication with microcontrollers. A hardware write protect function safeguards against accidental data corruption. Its non-volatile memory ensures that stored data remains intact even when power is removed. The self-timed write cycle simplifies the write operation process for the host microcontroller. The device is available in a small outline package, making it suitable for space-constrained applications.
