MAX 7000B Programmable Logic Device Family Data Sheet
Preliminary Information
Notes to tables:
(1)
This pin can function as either a JTAG port or a user I/O pin. If the device is configured to use the JTAG ports for
in-system programming, this pin is not available as a user I/O pin.
(2)
This pin may function as either a
VREF
pin or a user I/O pin. If this pin is programmed to be a
VREF
pin for using
the advanced I/O standards, this pin is not available as a user I/O pin.
(3)
The user I/O pin count includes dedicated input pins and all I/O pins.
(4)
EPM7512B devices in the 208-pin PQFP package support vertical migration from EPM7256E, EPM7256S, and
EPM7256B devices. EPM7512B devices contain additional I/O pins which are no connects on the EPM7256E,
EPM7256S, and EPM7256B devices. To support these additional I/O pins, EPM7512B devices have two additional
VCCIO1
(pin 105),
VCCIO2
(pin 207) and
GNDIO
(pins 51 and 158) pins that are no-connect pins on the EPM7256E,
EPM7256S, and EPM7256B devices. To achieve vertical migration between the EPM7256B and EPM7512B devices,
the no-connect pin 105 may be tied to
VCCIO1
, pin 207 may be tied to
VCCIO2
, and pins 51 and 158 may be tied to
GNDIO
on EPM7256B devices.
