GENERAL DESCRIPTION  
The MACHLV210 is a member of the high-  
performance EE CMOS MACH 2 device family. This  
device has approximately six times the logic macrocell  
capability of the popular PAL22V10 at an equal speed  
with a lower cost per macrocell. It is architecturally  
identical to the MACH210, with the addition of I/O  
pull-up/pull-down resistors and low-voltage, low-power  
operation.  
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 MACHLV210 has two kinds of macrocell: output  
and buried. The MACHLV210 output macrocell pro-  
vides 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 MACHLV210 provides 3.3-V operation with low-  
power CMOS technology. The patented design  
allows for minimal standby current without speed  
degradation by limiting the leakage current when  
signals are not switching. At less than 5 mA maximum  
standby current, the MACHLV210 is ideal for low-power  
applications.  
The MACHLV210 consists of four PAL blocks intercon-  
nected by a programmable switch matrix. The four PAL  
blocks are essentially “PAL22V16” structures complete  
with product-term arrays and programmable macro-  
cells, including additional buried macrocells. The switch  
The MACHLV210 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  
requirements.
