CPLDs and FPGAs are often referred to as high-capacity programmable logic devices (HCPLDs).

More Questions from Programmable Logic Device

• The four input-only pins found on devices in the MAX7000S family can be configured as specific high-speed control signals or as general user inputs.
• Based on the high-density architecture of logic cells, FLEX10K devices are generally classified as HCPLDs.
• A CPLD is basically a simplified PLD.
• The programming technologies that are used in FPGA devices include SRAM, flash, and antifuse, with flash being most common.
• Antifuse devices are volatile.
• The Boolean sum of the four product terms is called the sum-of-products.
• The PAL structure is able to perform any sum-of-products (SOP) operation.
• SPLD is a program language used by PLD software.
• The PAL has an AND and OR structure similar to a PROM, but in the PAL the inputs to the AND gates are programmable, whereas the inputs to the OR gate are hard-wired.
• All I/O pins in the MAX7000S family have a tristate buffer.
