MAX 3000A Programmable Logic Device Family Data Sheet
The VCCIO pins can be connected to either a 3.3-V or 2.5-V power supply,
depending on the output requirements. When the VCCIO pins are
connected to a 2.5-V power supply, the output levels are compatible with
2.5-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 VCCIO levels lower than 3.0 V
incur a nominally greater timing delay of tOD2 instead of tOD1. Inputs can
always be driven by 2.5-V, 3.3-V, or 5.0-V signals.
Table 8 summarizes the MAX 3000A MultiVolt I/O support.
Note:
(1)
When VCCIO is 3.3 V, a MAX 3000A device can drive a 2.5-V device that has 3.3-V
tolerant inputs.
Open-Drain Output Option
MAX 3000A devices provide an optional open-drain (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.
Slew-Rate Control
The output buffer for each MAX 3000A I/O pin has an adjustable output
slew rate that can be configured for low-noise or high-speed performance.
A faster slew rate provides high-speed transitions for high-performance
systems. However, these fast transitions may introduce noise transients
into the system. A slow slew rate reduces system noise, but adds a
nominal delay of 4 to 5 ns. When the configuration cell is turned off, the
slew rate is set for low-noise performance. Each I/O pin has an individual
EEPROM bit that controls the slew rate, allowing designers to specify the
slew rate on a pin-by-pin basis. The slew rate control affects both the
rising and falling edges of the output signal.
