EPF8452A集成电路（IC）的FPGA（现场可编程门阵列）规格书PDF中文资料

General Description

Altera’s Flexible Logic Element MatriX (FLEX®) family combines the benefits of both erasable programmable logic devices (EPLDs) and fieldprogrammable gate arrays (FPGAs). The FLEX 8000 device family is ideal for a variety of applications because it combines the fine-grained architecture and high register count characteristics of FPGAs with the high speed and predictable interconnect delays of EPLDs. Logic is implemented in LEs that include compact 4-input look-up tables (LUTs) and programmable registers. High performance is provided by a fast, continuous network of routing resources.
