GENERAL DESCRIPTION
The MACH111 is a member of Vantis’ high-performance EE CMOS MACH 1 & 2 families. This
device has approximately three times the logic macrocell capability of the popular PALCE22V10
without loss of speed.
®
The MACH111 consists of two PAL blocks interconnected by a programmable switch matrix.
The two PAL blocks are essentially “PALCE26V16” structures complete with product-term arrays
and programmable macrocells, which can be programmed as high speed or low power. 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 MACH111 macrocell provides either registered 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 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.
Vantis offers software design support for MACH devices through its own development system
and device fitters integrated into third-party CAE tools. Platform support extends across PCs,
Sun and HP workstations under advanced operating systems such as Windows 3.1, Windows 95
and NT, SunOS and Solaris, and HPUX.
