MACH 5 Family
MULTIPLE I/O AND DENSITY OPTIONS
The MACH 5 family offers six macrocell densities in a number of I/O options. This allows designers to choose
a device close to their logic density and I/O requirements, thus minimizing costs. For the same package type,
every density has the same pin-out. With proper design considerations, a design can be moved to a higher or
lower density part as required.
IEEE 1149.1 - COMPLIANT BOUNDARY SCAN TESTABILITY
Most MACH 5 devices have boundary scan registers and are compliant to the IEEE 1149.1 standard. This
allows functional testing of the circuit board on which the device is mounted through a serial scan path that
can access all critical logic nodes. Internal registers are linked internally, allowing test data to be shifted in and
loaded directly onto test nodes, or test node data to be captured and shifted out for verification. In addition,
these devices can be linked into a board-level serial scan path for more complete board-level testing.
IEEE 1149.1 - COMPLIANT IN-SYSTEM PROGRAMMING
Programming devices in-system provides a number of significant benefits including: rapid prototyping, lower
inventory levels, higher quality, and the ability to make in-field modifications. All MACH 5 devices provide in-
system programming (ISP) capability through their IEEE 1149.1-compliant Boundary Scan Test Access Port.
By using the IEEE 1149.1-compliant Boundary Scan Test Access Port as the communication interface
through which ISP is achieved, customers get the benefit of a standard, well-defined interface.
MACH 5 devices can be programmed across the commercial temperature and voltage range. The PC-based
LatticePRO software facilitates in-system programming of MACH 5 devices. LatticePRO software takes the
JEDEC file output produced by design implementation software, along with information about the Boundary
Scan chain, and creates a set of vectors that are used to drive the Boundary Scan chain. LatticePRO software
can use these vectors to drive a Boundary Scan chain via the parallel port of a PC. Alternatively, LatticePRO
software can output files in formats understood by common automated test equipment. This equipment can
then be used to program MACH 5 devices during the testing of a circuit board.
PCI COMPLIANT
MACH 5 devices in the -5/-6/-7/-10/-12 speed grades are compliant with the PCI Local Bus Specification
version 2.1, published by the PCI Special Interest Group (SIG). The 5-V devices are fully PCI-compliant. The
3.3-V devices are mostly compliant but do not meet the PCI condition to clamp the inputs as they rise above
VCC because of their 5-V input tolerant feature. MACH 5 devices provide the speed, drive, density, output
enables and I/Os for the most complex PCI designs.
