MAX 9000 Programmable Logic Device Family Data Sheet
The output buffer in each IOC has an adjustable output slew rate that can
be configured for low-noise or high-speed performance. A slower slew
rate reduces board-level noise and adds a nominal timing delay to the
output buffer delay (tOD) parameter. 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 on a pin-by-pin basis during
design entry or assign a default slew rate to all pins on a global basis. The
slew rate control affects both rising and falling edges of the output signals.
Output
Configuration
The MAX 9000 device architecture supports the MultiVolt I/O interface
feature, which allows MAX 9000 devices to interface with systems of
differing supply voltages. The 5.0-V devices in all packages can be set for
3.3-V or 5.0-V I/O pin operation. These devices have one set of VCC pins
for internal operation and input buffers (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 VCCINT level, input voltages are at TTL levels and are
therefore compatible with 3.3-V and 5.0-V inputs.
