GENERAL DESCRIPTION
The MACH211SP is a member of AMD’s EE CMOS Performance Plus MACH® 2 device family. This device has approximately six times the logic macrocell capability of the popular PAL22V10 without loss of speed. The MACH211SP consists of four PAL® blocks interconnected by a programmable switch matrix. The four PAL blocks are essentially “PAL26V16” structures complete with product-term arrays and 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 MACH211SP has two kinds of macrocell: output and buried. The MACH211SP 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.
