FLEX 10KE Embedded Programmable Logic Family Data Sheet
PCI Pull-Up Clamping Diode Option
FLEX 10KE devices have a pull-up clamping diode on every I/O,
dedicated input, and dedicated clock pin. PCI clamping diodes clamp the
signal to the VCCIO value and are required for 3.3-V PCI compliance.
Clamping diodes can also be used to limit overshoot in other systems.
Clamping diodes are controlled on a pin-by-pin basis. When VCCIO is
3.3 V, a pin that has the clamping diode option turned on can be driven by
a 2.5-V or 3.3-V signal, but not a 5.0-V signal. When VCCIO is 2.5 V, a pin
that has the clamping diode option turned on can be driven by a 2.5-V
signal, but not a 3.3-V or 5.0-V signal. Additionally, a clamping diode can
be activated for a subset of pins, which would allow a device to bridge
between a 3.3-V PCI bus and a 5.0-V device.
Slew-Rate Control
The output buffer in each IOE has an adjustable output slew rate that can
be configured for low-noise or high-speed performance. A slower slew
rate reduces system noise and adds a maximum delay of 4.3 ns. The fast
slew rate should be used for speed-critical outputs in systems that are
adequately protected against noise. Designers can specify the slew rate
pin-by-pin or assign a default slew rate to all pins on a device-wide basis.
The slow slew rate setting affects the falling edge of the output.
Open-Drain Output Option
FLEX 10KE devices provide an optional open-drain output (electrically
equivalent to open-collector output) for each I/O pin. This open-drain
output enables the device to provide system-level control signals (e.g.,
interrupt and write enable signals) that can be asserted by any of several
devices. It can also provide an additional wired-OR plane.
MultiVolt I/O Interface
The FLEX 10KE device architecture supports the MultiVolt I/O interface
feature, which allows FLEX 10KE devices in all packages to interface with
systems of differing supply voltages. These devices have one set of VCC
pins for internal operation and input buffers (VCCINT), and another set for
I/O output drivers (VCCIO).
