MACH 1 & 2 Families
SPEEDLOCKING FOR GUARANTEED FIXED TIMING
The unique MACH 1 & 2 architecture is designed for high performance—a metric that is met in
both raw speed, and even more importantly, guaranteed xed speed. The design of the switch
matrix and PAL blocks guarantee a xed pin-to-pin delay that is independent of the logic required
by the design. Other non-Lattice/Vantis CPLDs incur serious timing delays as product terms expand
beyond their typical 4 or 5 product term limits (Figure 8). Speed and SpeedLocking combine to
give designers easy access to the performance required in today’s designs.
