MAX 3000A Programmable Logic Device Family Data Sheet

Notes to tables:

(1)

See the Operating Requirements for Altera Devices Data Sheet.

(2)

Minimum DC input voltage is –0.5 V. During transitions, the inputs may undershoot to –2.0 V or overshoot to

5.75 V for input currents less than 100 mA and periods shorter than 20 ns.

(3)

All pins, including dedicated inputs, I/O pins, and JTAG pins, may be driven before VCCINT and VCCIO are

powered.

(4)

These values are specified under the recommended operating conditions, as shown in Table 13 on page 23.

(5)

The parameter is measured with 50% of the outputs each sourcing the specified current. The IOH parameter refers

to high–level TTL or CMOS output current.

(6)

The parameter is measured with 50% of the outputs each sinking the specified current. The IOL parameter refers to

low–level TTL, PCI, or CMOS output current.

(7)

This value is specified during normal device operation. During power-up, the maximum leakage current is

±300

μA.

(8)

This pull–up exists while devices are programmed in–system and in unprogrammed devices during power–up.

(9)

Capacitance is measured at 25

° C and is sample–tested only. The OE1 pin (high–voltage pin during programming)

has a maximum capacitance of 20 pF.

(10) The POR time for all MAX 3000A devices does not exceed 100

μs. The sufficient VCCINT voltage level for POR is

3.0 V. The device is fully initialized within the POR time after VCCINT reaches the sufficient POR voltage level.

(11) These devices support in-system programming for –40° to 100° C. For in-system programming support between –40°

and 0° C, contact Altera Applications.

Figure 9 shows the typical output drive characteristics of MAX 3000A

devices.
