EERAM in Automotive

microchiptechnologyinc_35490865747

EERAM offers a robust solution for data storage applications in Automotive that require (1) Constant data logging or (2) Applications that need to safely and securely save information before a random, user generated or system generated power loss event.

Data recorders, Data loggers and Black Boxes to store both critical system and user parameters are utilized in many areas of the vehicle such as ABS, Airbags, Transmission, Tire Pressure Monitoring, Seat Position, Power Train, Instrument Cluster, infotainment and Wiper Position systems. In applications such as these, data often needs to be constantly logged to memory – the infinite endurance of the EERAM enables engineers and system developers a way to easily get setup to achieve this. Not only this, when power is shut off to the system, the last parameters prior to power loss also need to be securely logged. The presence of the external capacitor ensures safe and secure data storage from the SRAM to the EEPROM during this power loss.

Product Highlights

Summary of EERAM Applications in Automotive

Application Why EERAM is needed?
Airbag Collect and Store info every second – blackbox
Telematics/Navigation To store navigation waypoints, bookmarks, user data on power up
Entertainment Download Station Information at power up, data changes constantly.
Instrument Cluster Track elapsed miles
Tire Pressure Tire Pressure Logs (data logger)
ABS - Stability Control Holds data from ABS sensors – information such as speed, turn radius and wheel rotation
Power Train Adaptive systems than manage the power train constantly write data to memory
