Synopsys XBC OTP NVM IP for Configuration
The Base Capacity Synopsys XBC OTP NVM offers a fast, field-programmable and low-power OTP NVM solution up to 128 Kb density. It is well suited for a variety of applications, including configuration, trimming, calibration, and encryption key storage.
Configuration
Device configurability lets one SoC with a range of processing and I/O options to be used in several systems that have variations in their feature sets. This provides a set of products with variations in features or customization of a standard product. An example would be automotive entertainment system modules using a processor that is used in different cars from the same manufacturer, each with different audio subsystem hardware that requires different settings. The system configuration can be accomplished by setting the operation of the chip at the factory and storing parameters in OTP memory.
Trimming & Calibration
Variations in chip processing and packaging operations result in deviations of analog circuits and sensors from their target specifications. To optimize the performance of the systems in which these components are placed, it is necessary to ¡°trim¡± interface circuitry to match a specific analog circuit or sensor. A trimming operation in OTP NVM compensates for variations in the analog circuits and sensors due to manufacturing variances of these components.
For example, automotive applications often require OTP-based trimming and calibration systems that interface with a car¡¯s analog circuits and sensors. Automotive trimming and calibration operations are required in secure vehicle ID (VID) storage, in-car communications, infotainment systems, gas tank vapor and tire pressures, temperatures of various subsystems both outside and under the hood, and positioning of electromechanical devices for brake, steering and other systems.
Encryption Key Storage
Secure encryption keys are found in devices such as encrypted flash memory drives, hard disk drives, and electronic point of sale systems. Like the Synopsys XSC OTP NVM IP, the XBC OTP NVM can be used for secure key storage. The XBC product offers key storage up to 128Kb density, while the XSC offers 16Kb to 32Kb density with additional security features.
