Device Structure

Structured as a non-volatile EEPROM with 128 bytes arranged in a 128 x 8-bit organization. SPI pins include serial clock, data in, and data out. 8-pin SOIC standard package for easy board mounting.

Performance Characteristics

Fast SPI interface enables quick data transfer up to 10MHz. Write cycle time is only 5ms. Low power operation, wide voltage range and robust temperature tolerance from -40°C to 125°C. Unlimited moisture sensitivity for varied environments.

Application Environments

Suitable for use in industrial, automotive, and consumer electronics. Ideal for parameter storage, configuration data retention, firmware update storage, and secure key storage.

Selection Guidelines

Choose this EEPROM if your system requires small capacity non-volatile memory, reliable operation at wide temperatures, surface-mount assembly, and fast SPI communication. Ensure your application matches the voltage and temperature range.

Usage Considerations

Make sure your microcontroller or host is compatible with SPI protocol and proper voltage levels (2.5V–5.5V). Observe correct timing for write cycles (5ms minimum). Solder and place using standard SOIC processes. Verify ROHS compliance and other regulatory certifications as required.
