This device has approximately twelve times the logic macrocell capability of the popular PALCE22V10 without loss of speed. The MACH231 consists of eight PAL® blocks interconnected by a programmable switch matrix. 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 MACH231 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...
