normal device operation, and permits an initial data pattern to be output at the device pins.
Allows the external circuitry and board-level interconnections to be tested by forcing a test
pattern at the output pins and capturing test results at the input pins.
Places the 1-bit bypass register between the TDI and TDO pins, which allows the BST
data to pass synchronously through the selected device to adjacent devices during
normal device operation.
MultiVolt I/O Interface
The FLEX 8000 device architecture supports the MultiVolt I/O interface
feature, which allows EPF81500A, EPF81188A, EPF8820A, and EPF8636A
devices to interface with systems with differing supply voltages. These
devices in all packages—except for EPF8636A devices in 84-pin PLCC
packages—can be set for 3.3-V or 5.0-V I/O pin operation. These devices
have one set of V
(VCCINT), and another set for I/O output drivers (VCCIO).
The VCCINT pins must always be connected to a 5.0-V power supply. With
a 5.0-V V
compatible with 3.3-V and 5.0-V inputs.
The VCCIO pins can be connected to either a 3.3-V or 5.0-V power supply,
depending on the output requirements. When the VCCIO pins are
connected to a 5.0-V power supply, the output levels are compatible with
5.0-V systems. When the VCCIO pins are connected to a 3.3-V power
supply, the output high is at 3.3 V and is therefore compatible with 3.3-V
or 5.0-V systems. Devices operating with V
incur a nominally greater timing delay of t
