Embedded Non-Volatile Memory IP for Analog/Mixed Signal Markets
Today’s analog and mixed signal applications require frequent calibration and trimming to ensure performance across process variations and environmental conditions. Some of the many analog applications include capacitative touchscreens, LCD drivers, and power management units. Key requirements are high reliability and small area. Typical non-volatile memory capacities range from 1kb to 64kb in process technologies from 180nm to 90nm.

Many analog and mixed signal applications require post-package or in-field calibration and trimming to fine tune circuit parameters for optimal performance. LCD drivers are one example of an analog/mixed signal application that relies heavily on the usage of non-volatile memory for calibration and trimming, as well as storage for copy protection keys.
Analog and mixed signal customers have replaced older efuse technology with Kilopass’ antifuse non-volatile memory IP due to its reliability and field programmability. Kilopass’ NVM technology has been used for:
- Calibration of the DACs/ADCs
- trimming of the analog references and DC/DC converter
- Configuration data
- Security keys
