Architecture
MachXO Family Data Sheet
of the devices also support differential input buffers. PCI clamps are available on the top Bank I/O buffers. The
PCI clamp is enabled after V CC , V CCAUX , and V CCIO are at valid operating levels and the device has been con-
figured. ?
?
The two pads in the pair are described as “true” and “comp”, where the true pad is associated with the positive
side of the differential input buffer and the comp (complementary) pad is associated with the negative side of
the differential input buffer.
2. Left and Right sysIO Buffer Pairs ?
The sysIO buffer pairs in the left and right Banks of the device consist of two single-ended output drivers and
two sets of single-ended input buffers (supporting ratioed and absolute input levels). The devices also have a
differential driver per output pair. The referenced input buffer can also be configured as a differential input buf-
fer. In these Banks the two pads in the pair are described as “true” and “comp”, where the true pad is associ-
ated with the positive side of the differential I/O, and the comp (complementary) pad is associated with the
negative side of the differential I/O.
Typical I/O Behavior During Power-up
The internal power-on-reset (POR) signal is deactivated when V CC and V CCAUX have reached satisfactory levels.
After the POR signal is deactivated, the FPGA core logic becomes active. It is the user’s responsibility to ensure
that all V CCIO Banks are active with valid input logic levels to properly control the output logic states of all the 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 maintain the blank 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 CC and V CCAUX supply the power to the FPGA core fabric, whereas the V CCIO supplies power to the I/O buf-
fers. In order to simplify system design while providing consistent and predictable I/O behavior, the I/O buffers
should be powered up along with the FPGA core fabric. Therefore, V CCIO supplies should be powered up before or
together with the V CC and V CCAUX supplies
Supported Standards
The MachXO sysIO buffer supports both single-ended and differential standards. Single-ended standards can be
further subdivided into LVCMOS and LVTTL. The buffer supports 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, bus-keeper latch or none) and open drain. BLVDS and LVPECL
output emulation is supported on all devices. The MachXO1200 and MachXO2280 support on-chip LVDS output
buffers on approximately 50% of the I/Os on the left and right Banks. Differential receivers for LVDS, BLVDS and
LVPECL are supported on all Banks of MachXO1200 and MachXO2280 devices. PCI support is provided in the top
Banks of the MachXO1200 and MachXO2280 devices. Table 2-8 summarizes the I/O characteristics of the devices
in the MachXO family.
Tables 2-9 and 2-10 show the I/O standards (together with their supply and reference voltages) supported by the
MachXO 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.
