APEX 20K Programmable Logic Device Family Data Sheet

APEX 20KE devices include an enhanced IOE, which drives the FastRow
interconnect. The FastRow interconnect connects a column I/O pin
directly to the LAB local interconnect within two MegaLAB structures.
This feature provides fast setup times for pins that drive high fan-outs
with complex logic, such as PCI designs. For fast bidirectional I/O timing,
LE registers using local routing can improve setup times and OE timing.
The APEX 20KE IOE also includes direct support for open-drain
operation, giving faster clock-to-output for open-drain signals. Some
programmable delays in the APEX 20KE IOE offer multiple levels of delay
to fine-tune setup and hold time requirements. The Quartus II software
compiler can set these delays automatically to minimize setup time while
providing a zero hold time.
Table 11
options in the Quartus II software.
The register in the APEX 20KE IOE can be programmed to power-up high
or low after configuration is complete. If it is programmed to power-up
low, an asynchronous clear can control the register. If it is programmed to
power-up high, an asynchronous preset can control the register.
shows how fast bidirectional I/O pins are implemented in APEX 20KE
devices. This feature is useful for cases where the APEX 20KE device
controls an active-low input or another device; it prevents inadvertent
activation of the input upon power-up.
