This device has approximately three times the capability of the popular PAL20RA10 without loss of speed. This device is designed for use in asynchronous as well as synchronous applications. The MACH215 consists of four PAL blocks interconnected by a programmable switch matrix. The four PAL blocks are essentially “PAL22RA8” structures complete with product-term arrays and programmable macrocells, individual register control product terms, and input registers. 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 MACH215 has two kinds of macrocell: output and input. The MACH215 output macrocell provides registered, latched, or com...
