GENERAL DESCRIPTION
The MACH210 is a member of AMD’s high-performance EE CMOS MACH 2 device family.
This device has approximately six times the logic macrocell capability of the popular PAL22V10 without loss of speed.
The MACH210 consists of four PAL blocks interconnected by a programmable switch matrix.
The four PAL blocks are essentially “PAL22V16” structures complete with product-term arrays and programmable macrocells, including additional 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 MACH210 has two kinds of macrocell: output and buried.
The MACH210 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 made by the designer or by the software.
All output macrocells can be connected to an I/O cell.
If a buried macrocell is desired, the internal feedback path from the macrocell can be used, which frees up the I/O pin for use as an input.
The MACH210 has dedicated buried macrocells which, in addition to the capabilities of the output macrocell, also provide input registers or latches for use in synchronizing signals and reducing setup time...
