Purpose

This document in intended for software engineer planning to generate public and

private keys, signature for their firmware and custom Efuse data for CEC1702 for their

system.

This document gives the introduction to the steps involved in CEC1702 Efuse

programming as well as the hardware and software requirements for the custom

Efuse programming once you get the blank part from Microchip.

1.1.2

Introduction

This document gives step by step information on programming the Efuse using the

CEC1702 Efuse Generator Tool. Following these steps will ensure that the CEC1702

part is programmed correctly each time without facing any difficulty. The CEC1702

Efuse Generator Tool is responsible for generating private and public key pairs,

verifying private-public key pair validity, disabling JTAG and ATE modes and

generating the Efuse programming values. The input from the user is GUI based and

is simple to use. The output from the tool is a binary file for programming the

CEC1702 part on the Clicker board using any JTAG programmer tool. The tool also

writes the private and public key in an output file protected with the password set by

the user while entering the parameters.
