GENERAL DESCRIPTION
The MACH221 is a member of Vantis’ high-performance EE CMOS MACH® 1 & 2 families. This
device has approximately nine times the logic macrocell capability of the popular PALCE22V10
without loss of speed.
The MACH221 consists of eight PAL® blocks interconnected by a programmable switch matrix. The
eight PAL blocks are essentially “PALCE26V12" structures complete with product-term arrays,
programmable macrocells, which can be programmed as high speed or low power, and buried
macrocells. The switch matrix connects the PAL blocks to each other and to all input pins,
providing a high degree of connectivity between the fully-connected PAL blocks. This allows
designs to be placed and routed efficiently.
The MACH221 has two kinds of macrocell: output and buried. The output macrocell provides
registered, latched, or combinatorial outputs with programmable polarity. If a registered
configuration is chosen, the register can be configured as D-type or T-type to help reduce the
number of product terms. The register type decision can be made by the designer or by the
software. All output macrocells can be connected to an I/O cell. If a buried macrocell is desired,
the internal feedback path from the macrocell can be used, which frees up the I/O pin for use as
an input.
The MACH221 has dedicated buried macrocells which, in addition to the capabilities of the output
macrocell, also provide input registers for use in synchronizing signals and reducing setup time
requirements.
