Architecture
MachXO Family Data Sheet
output data signals are multiplexed and provide a single signal to the I/O pin via the sysIO buffer. Figure 2-17
shows the MachXO PIO logic.
The tristate control signal is multiplexed from the output data signals and their complements. In addition a global
signal (TSALL) from a dedicated pad can be used to tristate the sysIO buffer.
The PIO receives an input signal from the pin via the sysIO buffer and provides this signal to the core of the device.
In addition there are programmable elements that can be utilized by the design tools to avoid positive hold times.

sysIO Buffer
Each I/O is associated with a flexible buffer referred to as a sysIO buffer. These buffers are arranged around the
periphery of the device in groups referred to as Banks. The sysIO buffers allow users to implement the wide variety
of standards that are found in today’s systems including LVCMOS, TTL, BLVDS, LVDS and LVPECL.
In the MachXO devices, single-ended output buffers and ratioed input buffers (LVTTL, LVCMOS and PCI) are pow-
ered using V CCIO . In addition to the Bank V CCIO supplies, the MachXO devices have a V CC core logic power supply,
and a V CCAUX supply that powers up a variety of internal circuits including all the differential and referenced input buf-
fers.
MachXO256 and MachXO640 devices contain single-ended input buffers and single-ended output buffers with
complementary outputs on all the I/O Banks.
MachXO1200 and MachXO2280 devices contain two types of sysIO buffer pairs.
1. Top and Bottom sysIO Buffer Pairs ?
The sysIO buffer pairs in the top and bottom Banks of the device consist of two single-ended output drivers and
two sets of single-ended input buffers (for ratioed or absolute input levels). The I/O pairs on the top and bottom
