STMicroelectronics Enhances Security with New Serial EEPROM Release

2025-04-10 products

Geneva, Thursday, 10 April 2025.
STMicroelectronics introduces Serial EEPROM featuring a 128-bit unique ID for enhanced security and traceability, offering capacities from 32 Kb to 2 Mb, crucial for inventory management.

Advanced Security Features and Technical Specifications

The newly announced M24xxx-U series, revealed on April 8, 2025, introduces a groundbreaking factory-programmed 128-bit read-only unique identifier (UID) that remains permanently locked after programming [1]. This innovative EEPROM series operates across a wide voltage range of 1.7V to 5.5V and supports I²C interface speeds up to 1 MHz [2]. The devices showcase exceptional durability with 4 million write cycles and an impressive 200-year data retention capability [1][2], positioning them as highly reliable solutions for long-term deployment.

Market Availability and Pricing

Initial market entry begins with two models: the 64-Kbit M24C64-UFMN6TP and the 128-Kbit M24128-UFMN6TP. The 64-Kbit version is available at $0.13 per unit, while the 128-Kbit model is priced at $0.15 for orders of 10,000 pieces [3]. The remaining variants in the product line, spanning from 32 Kbit to 2 Mbit capacities, are scheduled for release in Q2 2025 [2].

Enhanced Protection and Implementation

A significant security feature of these devices is the enhanced ESD protection, specifically designed to withstand 4 kV Human Body Model ESD events [3]. The UID implementation requires no additional code or circuitry to maintain security and doesn’t occupy the main EEPROM data space [2]. This design approach ensures seamless integration while maintaining robust security protocols for various applications across industrial, automotive, and consumer electronics sectors [1].
