DesignWare OTP XPM NVM IP

DesignWare OTP XPM embedded non-volatile memory (NVM) is built using standard, commercially available CMOS logic process technologies and is silicon proven to deliver high density, high performance, and highly reliable electrically field-programmable solutions at a low cost. More than 170 customers have integrated DesignWare XPM NVM IP in more than 400 designs from 180nm to 16nm. Applications range from 8Kb for security keys to multiple instances of 1Mb for program code storage.

Antifuse-based DesignWare OTP XPM NVM IP is an ideal efuse replacement solution.  It is a field programmable memory that provides higher security, larger capacity with a smaller footprint, and lower active and standby power. Because XPM is also foundry agnostic, it allows you to keep the IP in your design if and when you decide to port to another foundry.
