eFUSE Programming on a Device Programmer

eFUSE Programming on a Device Programmer

This application note provides the file preparation instructions for programming the eFUESE in Zynq®-7000 All Programmable (AP) SoC devices on a device programmer. Device programmers are effective for high-volume, off-board device programming and preprogramming and securing sensitive data in the eFUSE before devices are sent for assembly at a board contract manufacturing site.


In Zynq-7000 AP SoC devices, the eFUSE is one-time programmable (OTP), non-volatile, and includes non-erasable settings. These settings enable device security features, such as boot image authentication and encryption, and enable a user-defined 32-bit value.
