The BR93L56RF-WFE2 is a serial EEPROM (Electrically Erasable Programmable Read-Only Memory) manufactured by Rohm Semiconductor. It communicates using the Microwire interface, a synchronous serial protocol. The part number '56' suggests a memory capacity around 4Kbits. It's designed for storing small to medium amounts of non-volatile data in a variety of applications, such as storing configuration settings, calibration parameters, or user preferences.

Applications:

• Storing configuration data in electronic devices
• Storing calibration coefficients in sensors
• Storing user-defined settings in consumer electronics
• Parameter storage in industrial control systems
• Storing serial numbers or identification data

Features:

• Memory Size: 4Kbit (Likely organized as 256 x 16)
• Interface: Microwire Serial Interface
• Operating Voltage: Operates between 1.8V and 5.5V
• Low Voltage Operation: Designed for low voltage applications with 'L' in part number.
• Low Power Consumption: Minimizes power consumption
• Data Retention: Offers long-term data retention (typically 100 years)
• Write Endurance: High write cycle endurance (typically 1,000,000 cycles)
• Package: Small surface mount package (likely SOP or similar based on RF)
• RoHS Compliant: Compliant with RoHS environmental standards

Benefits:

• Non-Volatile Storage: Data is retained even when power is off.
• Simple Interface: Easy to interface with microcontrollers using Microwire.
• Low Power: Extends battery life in portable applications.
• Small Size: Compact package saves board space.
• Reliable: Ensures data integrity with high data retention and write endurance.

Additional Details:

The Microwire interface uses a clock, data input, and data output line for communication. The specific suffix '-WFE2' designates package characteristics, temperature range, and environmental compliance information. The 'RF' likely refers to the package style. The 'L' likely stands for low voltage operation. The operating temperature is likely -40°C to +85°C. Datasheets contain detailed information on timing diagrams, pin configurations, and power consumption specifications. The device likely supports block write protection mechanisms.
