This chapter provides information about hot-socketing specifications, power-on reset
(POR) requirements, and their implementation in MAX
MAX V devices offer hot socketing, also known as hot plug-in or hot swap, and
power sequencing support. You can insert or remove a MAX V device in a system
during system operation without causing undesirable effects to the running system
bus. The hot-socketing feature removes some of the difficulty when using MAX V
devices on PCBs that contain a mixture of 3.3-, 2.5-, 1.8-, and 1.5-V devices.
The MAX V hot-socketing feature provides the following:

MAX V devices offer the hot-socketing feature without the need for external
components or special design requirements. The advantages of hot-socketing support
in MAX V devices includes the following:

■
Altera uses GND as a reference for the hot-socketing and I/O buffers circuitry
designs. To ensure device reliability and compliance to the hot-socketing
specifications, you must connect GND between boards before connecting the V

The device can be driven before and during power up or power down without
damaging the device.
I/O pins remain tri-stated during power up. The device does not drive out before
or during power up, thereby affecting other operating buses.
Signal pins do not drive the V
to the device I/O pins do not power the device V
using internal paths. This is true if the V
