MAX 7000A Programmable Logic Device 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 for input currents
less than 100 mA and periods shorter than 20 ns.
(3) For EPM7128A and EPM7256A devices only, V_CC must rise monotonically.
(4) In MAX 7000AE devices, all pins, including dedicated inputs, I/O pins, and JTAG pins, may be driven before
V_CCINT and V_CCIO are powered.
(5) These devices support in-system programming for –40° to 100° C. For in-system programming support between
–40° and 0° C, contact Altera Applications.
(6) These values are specified under the recommended operating conditions shown in Table 14 on page 28.
(7) The parameter is measured with 50% of the outputs each sourcing the specified current. The I_OH parameter refers
to high-level TTL or CMOS output current.
(8) The parameter is measured with 50% of the outputs each sinking the specified current. The I_OL parameter refers to
low-level TTL or CMOS output current.
(9) This value is specified for normal device operation. For MAX 7000AE devices, the maximum leakage current during
power-up is ±300 µA. For EPM7128A and EPM7256A devices, leakage current during power-up is not specified.
(10) For EPM7128A and EPM7256A devices, this pull-up exists while a device is programmed in-system.
(11) For MAX 7000AE devices, this pull-up exists while devices are programmed in-system and in unprogrammed
devices during power-up.
(12) 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.
(13) The POR time for MAX 7000AE devices (except MAX 7128A and MAX 7256A devices) does not exceed 100 µs. The
sufficient V_CCINT voltage level for POR is 3.0 V. The device is fully initialized within the POR time after V_CCINT
reaches the sufficient POR voltage level.
