August 11, 2015, Seoul – STMicroelectronics (ST), a global semiconductor company serving customers across a wide range of electronic applications, has launched the M95M02, the industry's first 2Mbit (megabit) EEPROM product to receive AEC-Q100 certification. This product expands the parameter storage and management capabilities for complex automotive modules.

New advanced applications such as hybrid vehicles, electric vehicles, and high-performance truck engines must maximize power conversion efficiency by extensively utilizing various parameters such as airflow, fuel injection, exhaust gas, and battery charging for eco-friendly driving. Similarly, in automotive safety-related applications such as airbags, body accident recorders, and brake controllers, the importance of processing and storing large amounts of parameter input data, such as object detection, 3-axis motion, wheel speed, and steering angle, is growing.

ST's new M95M02 EEPROM combines large storage capacity with high cycling and data retention performance (4 million cycles per byte, clock frequency of up to 10 MHz, and a 100-year warranty). These features help provide superior accuracy and flexibility during ECU (Electronic Control Unit) operation. This is because the ECU's complex control algorithms maximize accuracy, helping to smoothly monitor environmental parameters in real time.

This new product is the industry's only 2-megabit EEPROM that provides an additional 256-byte lockable page to securely store module traceability, identification numbers, and mission-critical data. This lockable page is equipped with specific access commands to avoid interaction with standard parts of the memory array. Mission-critical data can be updated and cycled, or restricted to read-only mode for security purposes.

ST's M95M02-A125 EEPROM has passed AEC-Q100 Grade 1 reliability standard tests and operates at 2.5V up to 125°C. This product enhances overall design flexibility by expanding the capacity of ST's automotive EEPROM from 2 kilobits (2K) to a maximum of 2 megabits in a single SO8N footprint package. The M95M02-A125 is currently in mass production, with pricing starting at $1.50 for orders of 1,000 units.
