APEX 20K Programmable Logic Device Family Data Sheet
Preliminary Information
Notes to tables:
(1)
See the Operating Requirements for Altera Devices Data Sheet in this data book.
(2)
Minimum DC input is –0.5 V. During transitions, the inputs may undershoot to –2.0 V or overshoot to 4.6 V for
input currents less than 100 mA and periods shorter than 20 ns.
(3)
Numbers in parentheses are for industrial-temperature-range devices.
(4)
Maximum VCC rise time is 100 ms, and VCC must rise monotonically.
(5)
All pins, including dedicated inputs, clock, I/O, and JTAG pins, may be driven before VCCINT and VCCIO are
powered.
(6)
Typical values are for TA = 25° C, VCCINT = 2.5 V, and VCCIO = 2.5 V or 3.3 V.
(7)
These values are specified under the APEX 20K device recommended operating conditions, shown in Table 16 on
(8)
The APEX 20K input buffers are compatible with 2.5-V and 3.3-V (LVTTL and LVCMOS). Additionally, the input
buffers are 3.3-V PCI compliant when VCCIO and VCCINT meet the relationship shown in Figure 34 on page 77.
(9)
The IOH parameter refers to high-level TTL, PCI, or CMOS output current.
(10) The IOL parameter refers to low-level TTL, PCI, or CMOS output current. This parameter applies to open-drain pins
as well as output pins.
(11) Pin pull-up resistance values will be lower if an external source drives the pin higher than VCCIO.
(12) Capacitance is sample-tested only.
Figure 34 shows the relationship between VCCIO and VCCINT for 3.3-V PCI
compliance.
