STMicroelectronics claimed the industry’s first AEC-Q100-qualified 2Mbit EEPROM device opening up new opportunities in parameter storage and management in complex automotive modules. These include new advanced applications such as hybrid, electric, or high-power truck engines that require extensive use of various parameters, including the information on air volume, fuel injection, exhaust, or battery charge, to maximize power-conversion efficiency for greener driving, said ST. The new memory device also may be used in automotive-safety applications, such as event recording for airbag or body and braking controllers, which rely on storing and processing large amounts of parametric inputs that include object detection, 3-axis motion, wheel speed, and steering angle, added the company.
Key features of the M95M02 EEPROM include large storage capacity with high cycling and data-retention performance (4 million cycles per byte, clock frequency up to 10MHz, and 100 years guaranteed), enabling higher accuracy and flexibility in electronic control unit (ECU) operation. Other features include an additional lockable page of 256 bytes to store module tracing ability, identification numbers, or mission-critical data. The lockable page has specific access instructions to avoid interaction with the standard part of the memory array, said ST. In addition, mission-critical data can be updated and cycled or locked into a read-only mode for more security.
The M95M02-A125 EEPROMs have passed the AEC-Q100 Grade-1 reliability criteria tests and operate at 2.5 V up to 125°C. They extend the ST Automotive EEPROM density range from 2K up to 2 Mbit in a single SO8N footprint package.
Availability: The M95M02-A125 is available in volume.
Pricing: Starts from $1.50 for orders of 1000 pieces.
