DesignWare OTP Gusto High-Density NVM IP

DesignWare OTP Gusto NVM IP is the industry’s first and only 4Mb embedded non-volatile memory (NVM). It is built using standard, commercially available CMOS logic process technologies and utilizes an 2T antifuse bitcell with proven security critical for secure code storage applications. Broadening NVM storage capacity beyond just configuration and keys — with Gusto you can now store code, such as firmware, on-chip.

The high-density DesignWare OTP Gusto NVM IP has 4X higher performance than previous solutions, 10X less active power consumption, and 40X less standby power consumption. The measurable system cost benefits reduce overall BOM by replacing serial Flash or serial EEPROM.
