Abstract
Some examples described herein relate to multi-chip devices. In an example, a multi-chip device includes first and second chips. The first chip includes a power supply circuit and a logic circuit. The first and second chips are coupled together. The second chip is configured to receive power from the power supply circuit. The second chip includes a programmable circuit, a pull-up circuit, and a detector circuit. The detector circuit is configured to detect a presence of a power voltage on the second chip and responsively output a presence signal. The power voltage on the second chip is based on the power from the power supply circuit. The logic circuit is configured to generate a pull-up signal based on the presence signal. The pull-up circuit is configured to receive the pull-up signal and configured to pull up a voltage of a node of the programmable circuit responsive to the pull-up signal.
