RM24EP128A-BSNC-T

Memory IC Overview

The RM24EP128A-BSNC-T is a 128-Kbit I2C EEPROM-compatible boot memory utilizing Adesto's CBRAM technology. It operates on a single 2.7V to 3.6V supply and supports I2C bus modes up to 1MHz. The device features a 64-byte page size, byte write times of 50µs, and page write times of 1ms. It offers gamma and e-beam sterilization tolerance of 50 kGy, 100 write cycle endurance, and 10-year data retention at 70°C. Available in an 8-pin SOIC package with commercial temperature range (0°C to +70°C).

Memory IC Feature Summary

• Gamma and e-beam sterilization tolerance up to 50 kGy for medical applications.
• CBRAM resistive memory technology providing high endurance and low power consumption.
• I2C interface supporting standard, fast, and high-speed modes up to 1MHz.
• Hardware write protection via the WP pin to secure the entire memory array.

Memory IC Applications

• Sterilizable medical devices requiring durable non-volatile storage.
• Boot memory systems needing radiation-hardened components.
• IoT sensors operating in harsh environments with limited power budgets.

Memory IC Procurement Notes

Verify the specific ordering suffix 'T' corresponds to Tape & Reel packaging rather than Tube ('B'). Confirm the 'C' grade indicates the commercial temperature range of 0°C to +70°C. Ensure the 'SN' package designation matches the required 8-lead SOIC footprint. Cross-reference the density code '128' to confirm 128-Kbit capacity. Check for any RoHS compliance documentation if halogen-free status is critical for your assembly process.

Memory IC Selection Notes

Select this component when radiation hardness or sterilization resistance is required for non-volatile storage. It is suitable for applications needing low voltage operation between 2.7V and 3.6V. Consider it for designs where hardware write protection is necessary to prevent accidental data modification. Evaluate the 100-cycle endurance limit against your application's write frequency requirements before choosing over higher-endurance alternatives.

Memory IC Part Context
