EPF8820AQC208-3N Tóm tắt

The Altera EPF8820AQC208-3N is a member of the FLEX 8000 programmable logic device family, integrating approximately 8,000 usable gates, 672 logic cells (LEs), and 152 user I/Os in a 208-pin FQFP (PQFP) package. It is fabricated on a 0.42 µm CMOS SRAM process and operates from a 5 V supply with a commercial 0 °C to 70 °C temperature range.

An FPGA (Field-Programmable Gate Array) is a semiconductor IC whose logic and interconnect resources are configured by the end user via a bitstream loaded into on-chip SRAM configuration memory. FPGAs sit above CPLDs, ASSPs, and discrete logic in the programmable logic hierarchy and below custom ASICs in unit cost but above them in design flexibility and time-to-market. The FLEX 8000 family pioneered high-density, register-rich CMOS PLDs targeting glue logic, bus integration, and system-level integration that previously required multiple 32-bit bus devices in separate packages.

Key features of the EPF8820AQC208-3N include in-circuit reconfigurability (ICR) via external configuration devices or a system controller, fast 16-bit loadable counter performance rated at 95 MHz, a 16-to-1 multiplexer delay of 7.9 ns at the -3 speed grade, and CMOS SRAM-based configuration elements that allow unlimited reconfiguration. The 152 user I/O count supports wide parallel bus interfaces, and the high-pin-count 208-FQFP package integrates multiple 32-bit buses into a single device. Configuration is performed at system power-up using data stored in an industry-standard parallel EPROM or via Altera EPC1, EPC1213, EPC1064, or EPC1441 serial configuration devices.

Architecturally, FLEX 8000 devices use Logic Elements (LEs) tied together by a continuous FastTrack interconnect, with embedded array blocks (EABs) for memory-intensive functions. The 0.42 µm process supports up to 16,000 usable gates, and the speed grade -3N indicates the -3 speed bin (slower than -4) with N denoting a non-lead-free or commercial finish variant. Typical applications include industrial control, telecom interface cards, and legacy bus-bridge replacement.

Typical applications include industrial automation control, legacy telecom interface cards, PCI bus bridges, glue-logic consolidation in 5 V industrial systems, and educational/hobbyist development platforms. The wide I/O count makes it suitable for interfacing with parallel SRAM, FIFOs, and microprocessors of its era. Design with care when migrating to modern 3.3 V systems; the 5 V I/Os are tolerant but not strictly 3.3 V-compliant.

When designing with this FPGA, observe that configuration data is volatile and must be reloaded on every power-up. Ensure proper decoupling of VCCINT and VCCIO rails, and verify timing closure against the -3 speed grade rather than the -2 or -4 grades. For new designs, consider that FLEX 8000 is in legacy lifecycle status.

This page synthesizes distributor pricing, same-family drop-in alternatives, FQFP-208 footprint compatibility data, and practical configuration-design notes not found in the original FLEX 8000 datasheet - useful for engineers maintaining legacy 5 V systems.
