Embedded Non-Volatile Memory IP for Automotive Markets
Increasing complexity in automotive systems has driven new applications for low-cost, secure and field-programmable non-volatile memory. The proliferation of sensors to monitor everything from environmental conditions to engine control has increased the need for analog calibration and trimming, ideal for non-volatile memory (NVM) technology. Another automotive application where Kilopass embedded NVM is used is for code storage for all the various microcontrollers and DSPs used to control various aspects of the car’s operating systems. Finally, in-car infotainment systems are now rivaling many home entertainment systems and will require the same media content protection using security keys. Typical NVM capacities for automotive applications range from 1kbit to +4Mbit and target all process nodes from 180nm and below.

DSPs are used in automotive applications to process real-time sensor data to control engine performance, safety systems, and electric motors and power balancing for hybrid electric vehicles. These applications require different sets of algorithms which can be stored in NVM as program code.
Kilopass’ embedded NVM technology has been used for:
- Code storage for microcontrollers and DSPs
- Calibration and trimming for sensors
- Security keys for infotainment systems
