Copy CPLD EPM7128BUC169 IC Eeprom Firmware and rewrite the jed file to new CPLD EPM7128BUC169 which will provide the same functions as original master CPLD serve as restoration purpose, unlock fuse bit on the CPLD EPM7128BUC processor;

All MAX 7000A devices contain a programmable security bit that controls access to the data programmed into the device. When this bit is programmed, a design implemented in the device cannot be copied or retrieved which will require to unlock cpld epm ic memory protection.

This feature provides a high level of design security because programmed data within EEPROM cells is invisible. The security bit that controls this function, as well as all other programmed data, is reset only when the device is reprogrammed.

MAX 7000A devices are fully tested. Complete testing of each

programmable EEPROM bit and all internal logic elements ensures 100% programming yield. AC test measurements are taken under conditions equivalent to those shown. Test patterns can be used and then erased during early stages of the production flow.
