APEX 20K Programmable Logic Device Family Data Sheet
General
Description

20K devices are the first PLDs designed with the MultiCore
architecture, which combines the strengths of LUT-based and product-
term-based devices with an enhanced memory structure. LUT-based logic
provides optimized performance and efficiency for data-path, register-
intensive, mathematical, or digital signal processing (DSP) designs.
Product-term-based logic is optimized for complex combinatorial paths,
such as complex state machines. LUT- and product-term-based logic
combined with memory functions and a wide variety of MegaCore and
AMPP functions make the APEX 20K device architecture uniquely suited
for system-on-a-programmable-chip designs. Applications historically
requiring a combination of LUT-, product-term-, and memory-based
devices can now be integrated into one APEX 20K device.
APEX 20KE devices are a superset of APEX 20K devices and include
additional features such as advanced I/O standard support, CAM,
additional global clocks, and enhanced ClockLock clock circuitry. In
addition, APEX 20KE devices extend the APEX 20K family to 1.5 million
gates. APEX 20KE devices are denoted with an “E” suffix in the device
name (e.g., the EP20K1000E device is an APEX 20KE device).
