architecture description
Description
The XCR3128XL is a 3.3V 128 macrocell CPLD targeted at
power sensitive designs that require leading edge programmable logic solutions. A total of eight function blocks provide
3,000 usable gates. Pin-to-pin propagation delays are
6.0 ns with a maximum system frequency of 145 MHz.
TotalCMOS Design Technique for Fast
Zero Power
Xilinx offers a TotalCMOS CPLD, both in process technology and design technique. Xilinx employs a cascade of
CMOS gates to implement its sum of products instead of
the traditional sense amp approach. This CMOS gate implementation allows Xilinx to offer CPLDs that are both high
performance and low power, breaking the paradigm that to
have low power, you must have low performance. Refer to
Figure 1 and Table 1 showing the I

XCR3128XL TotalCMOS CPLD (data taken with eight
resetable up/down, 16-bit counters at 3.3V, 25°C).
