FINAL COM’L: -12/15/20, Q-20/25 MACH435-12/15/20, Q-20/25 High-Density EE CMOS Programmable Logic Lattice Semiconductor DISTINCTIVE CHARACTERISTICS s 84 Pins in PLCC s 128 Macrocells s 12 ns tPD s 83.3 MHz fCNT s 70 Inputs with pull-up resistors s 64 Outputs s 192 Flip-flops — 128 Macrocell flip-flops — 64 Input flip-flops s Up to 20 product terms per function, with XOR GENERAL DESCRIPTION The MACH435 is a member of our high-performance EE CMOS MACH 4 family. This device has approximately twelve times the macrocell capability of the popular PAL22V10, with significant density and functional features that the PAL22V10 does not provide. The MACH435 consists of eight PAL blocks interconnected by a programmable central switch matrix. The central 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. Routability is further enha...
