IN-SYSTEM PROGRAMMING
In-system programming allows the MACH211SP to be programmed while soldered onto a system board.
Programming the MACH211SP in-system yields numerous benefits at all stages of development: prototyping, manufacturing, and in the field.
Since insertion into a programmer isn’t needed, multiple handling steps and the resulting bent leads are eliminated.
The design can be modified in-system for design changes and debugging while prototyping, programming boards in production, and field upgrades.
The MACH211SP offers advantages not available in other CPLD architectures with in-system programming.
MACH devices have extensive routing resources for pin-out retention; design changes resulting in pin-out changes for other CPLDs cancel the advantages of in-system programming.
The MACH211SP can be employed in any JTAG (IEEE 1149.
1) compliant chain.
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 d...
