ABSTRACT:
In a fuse programmable voltage generator providing an optimal internal voltage VCCINT, a counter outputs various values to a voltage down comparator to output corresponding internal voltages VCCINT until a desired voltage is obtained. Once the desired internal voltage VCCINT is determined, the counter is disabled and a fuse circuit is configured to substantially maintain the output of the desired internal voltage VCCINT.
