Typical I/O Behavior During Power-up
The internal power-on-reset (POR) signal is deactivated when V
After the POR signal is deactivated, the FPGA core logic becomes active. It is the user’s responsibility to ensure
that all other V
I/O banks that are critical to the application. The default configuration of the I/O pins in a blank device is tri-state
with a weak pull-up to VCCIO. The I/O pins will not take on the user configuration until VCC, VCCAUX and VCCIO
have reached satisfactory levels at which time the I/Os will take on the user-configured settings.
The V
ers. In order to simplify system design while providing consistent and predictable I/O behavior, it is recommended
that the I/O buffers be powered-up prior to the FPGA core fabric. V

Supported Standards
The LatticeXP sysIO buffer supports both single-ended and differential standards. Single-ended standards can be
further subdivided into LVCMOS, LVTTL and other standards. The buffers support the LVTTL, LVCMOS 1.2, 1.5,
1.8, 2.5 and 3.3V standards. In the LVCMOS and LVTTL modes, the buffer has individually configurable options for
drive strength, bus maintenance (weak pull-up, weak pull-down, or a bus-keeper latch) and open drain. Other sin-
gle-ended standards supported include SSTL and HSTL. Differential standards supported include LVDS, BLVDS,
LVPECL, differential SSTL and differential HSTL. Tables 2-7 and 2-8 show the I/O standards (together with their
supply and reference voltages) supported by the LatticeXP devices. For further information on utilizing the sysIO
buffer to support a variety of standards please see the details of additional technical documentation at the end of
this data sheet.
