CoolRunner-II CPLD Family

Table 2 shows the CoolRunner-II CPLD package offering
with corresponding I/O count. All packages are surface
mount, with over half of them being ball-grid technologies.
The ultra tiny packages permit maximum functional capacity
in the smallest possible area. The CMOS technology used
in CoolRunner-II CPLDs generates minimal heat, allowing
the use of tiny packages during high-speed operation.
There are at least two densities present in each package
with three in the VQ100 (100-pin 1.0mm QFP) and TQ144
(144-pin 1.4mm QFP), and in the FT256 (256-ball 1.0mm
spacing FLBGA). The FT256 is particularly important for
slim dimensioned portable products with mid- to high-den-
sity logic requirements.

Table 3 details the distribution of advanced features across
the CoolRunner-II CPLD family. The family has uniform
basic features with advanced features included in densities
where they are most useful. For example, it is very unlikely
that four I/O banks are needed on 32 and 64 macrocell
parts, but very likely they are for 384 and 512 macrocell
parts. The I/O banks are groupings of I/O pins using any
one of a subset of compatible voltage standards that share
the same V_CCIO level. (See Table 4 for a summary of
CoolRunner-II I/O standards.) The clock division capability
is less efficient on small parts, but more useful and likely to
be used on larger ones. DataGATE, an ability to block and
latch inputs to save power, is valuable in larger parts, but
brings marginal benefit to small parts.
