Notes:
(1) When the IEEE Std. 1149.1 (JTAG) interface is used for in-system programming or boundary-scan testing, four I/O
pins become JTAG pins.
(2) Contact Altera for up-to-date information on available device package options.
(3) All 0.8-mm Ultra FineLine BGA packages are footprint-compatible via the SameFrameTM pin-out feature. Therefore,
designers can design a board to support a variety of devices, providing a flexible migration path across densities
and pin counts. Device migration is fully supported by Altera development tools. See “SameFrame Pin-Outs” on
page 14 for more details.

MAX 7000B devices use CMOS EEPROM cells to implement logic
functions. The user-configurable MAX 7000B architecture accommodates
a variety of independent combinatorial and sequential logic functions.
The devices can be reprogrammed for quick and efficient iterations
during design development and debug cycles, and can be programmed
and erased up to 100 times.
MAX 7000B devices contain 32 to 512 macrocells that are combined into
groups of 16 macrocells, called logic array blocks (LABs). Each macrocell
has a programmable-AND/fixed-ORarray and a configurable register with
independently programmable clock, clock enable, clear, and preset
functions. To build complex logic functions, each macrocell can be
supplemented with both shareable expander product terms and high-
speed parallel expander product terms to provide up to 32 product terms
per macrocell.
