Introduction

For more information on equivalent macrocells, refer to the
MAX II Logic Element to Macrocell Conversion Methodology
white
paper.
MAX II devices are available in three speed grades: -3, -4, -5 with -3 being
the fastest. These speed grades represent overall relative performance,
not any specific timing parameter. For propagation delay timing
numbers within each speed grade and density, see the chapter on
DC &
Switching Characteristics.
Table 1–2
shows MAX II device speed-grade
offerings.

MAX II devices are available in space-saving FineLine BGA
®
, Micro
FineLine BGA, and thin quad flat pack (TQFP) packages (see
Tables 1–3
and
1–4).
MAX II devices support vertical migration within the same
package (e.g., you can migrate between the EPM570, EPM1270, and
EPM2210 devices in the
256-pin FineLine BGA package). Vertical migration means that you can
migrate to devices whose dedicated pins and JTAG pins are the same and
power pins are subsets or supersets for a given package across device
densities. The largest density in any package has the highest number of
power pins; you must layout for the largest planned density in a package
to provide the necessary power pins for migration. For I/O pin migration
across densities, cross reference the available I/O pins using the device
pin-outs for all planned densities of a given package type to identify
which I/O pins can be migrated. The Quartus
®
II software can
automatically cross reference and place all pins for you when given a
device migration list.
