EPF8820ARI208-2N Visão geral
A Field-Programmable Gate Array (FPGA) is a type of integrated circuit that can be configured by the customer after manufacturing to implement arbitrary digital logic. FPGAs sit in the programmable logic hierarchy beneath ASICs (Application-Specific Integrated Circuits) but above simple PLDs (Programmable Logic Devices), offering a balance of density, performance, and time-to-market flexibility. The FLEX 8000 family specifically targets glue-logic, bus interfacing, and state-machine applications where discrete TTL or CPLD integration would be too large or too slow. EPF8820ARI208-2N operates on 5.0 V core supply and is supported by the MAX+PLUS II and Quartus design toolchains.
Key features of this device include FastTrack continuous routing architecture, four dedicated input pins, a global Clear signal, programmable output slew-rate control, and JTAG-compliant boundary-scan support per IEEE Std 1149.1. Each LAB contains eight logic elements (LEs), each LE consisting of a 4-input LUT, a programmable register, and carry/chain logic for arithmetic operations. The 208-pin RQFP package provides ample signal margin for legacy bus architectures including PCI, ISA, and VME.
Typical applications include telecommunications backplane glue logic, industrial motor-control state machines, legacy PCI interface bridges, and military/aerospace digital subsystems. The -2 speed grade is the most commonly specified FLEX 8000 variant, offering a balance of timing margin and cost for non-critical-path designs.
When designing with this device, engineers should note that the FLEX 8000 family is NRND (Not Recommended for New Designs) - modern Cyclone or MAX series devices are recommended for new projects. Existing designs should verify pinout compatibility before migration and consult Altera's migration guides for footprint and timing deltas. Designers should also provision 5.0 V tolerance on I/O banks interfacing with legacy 5 V logic families.

Aplicações típicas
EPF8820ARI208-2N é adequado para 6 aplicaçãos: Telecommunications Backplane Glue Logic, Industrial Motor Control State Machines, Legacy PCI Bridge and Interface Logic, Military and Aerospace Digital Subsystems, VME and VXI Bus Interface Cards, Glue-Logic Consolidation for Legacy ASICs.
Telecommunications Backplane Glue Logic
The EPF8820ARI208-2N's 504 logic elements and 78 user I/O pins provide sufficient density to bridge legacy telecom backplanes, replacing multiple discrete TTL/CMOS glue-logic ICs with a single reconfigurable device. With 5.0V tolerant I/O and JTAG boundary-scan support per IEEE 1149.1, the part interfaces seamlessly to 1990s-vintage telecom ASICs and bus architectures including H.110, SCSA, and MVIP. Its FastTrack continuous interconnect simplifies routing for bus arbitration and timing-critical state machines, while the RQFP-208 package accommodates the dense backplane signal count. The -2 speed grade offers adequate margin for typical 33-50 MHz telecom bus speeds.
Recomendado
Industrial Motor Control State Machines
In industrial motor-control designs of the late 1990s and 2000s, the EPF8820ARI208-2N served as the central state-machine controller, sequencing PWM signals, monitoring encoder feedback, and implementing safety interlocks. The 504 LEs comfortably handle multi-axis control algorithms while the 78 I/Os interface to optocouplers, gate drivers, and resolver-to-digital converters. The 5.0V core supply and industrial temperature range (with Q-grade variants) suit factory-floor environments, and the FastTrack interconnect ensures deterministic timing for closed-loop control loops. Engineers migrating legacy systems retain design continuity through pin-compatible FLEX 8000 variants.
Recomendado
Legacy PCI Bridge and Interface Logic
The EPF8820ARI208-2N was widely deployed as a PCI bridge interface device, implementing bus arbitration, address decoding, and interrupt steering between PCI 2.2 and legacy ISA/VME/PCI peripherals. Its 78 user I/Os accommodate the 32-bit PCI bus signals plus auxiliary control logic, while the 504 LEs provide sufficient density for state machines and FIFO control. The 5.0V I/O tolerance matches the PCI 5V signaling environment, and the -2 speed grade satisfies the 33 MHz PCI clock period. Existing designs can leverage the JTAG boundary-scan for in-system debugging and configuration.
Recomendado
Military and Aerospace Digital Subsystems
Military and aerospace programs adopted the EPF8820ARI208-2N for radar signal processing interfaces, navigation control logic, and avionic bus bridges due to its SRAM-based reconfigurability allowing in-field firmware updates. The RQFP-208 package withstands standard MIL-STD-810 environmental screening, and the industrial temperature range supports extended operating envelopes. Legacy defense programs continue to maintain FLEX 8000 designs through the secondary market, with brokers stocking NRND parts for lifecycle support beyond the original Altera EOL roadmap.
Recomendado
VME and VXI Bus Interface Cards
VMEbus and VXI instrumentation chassis relied on the EPF8820ARI208-2N to implement bus-master controllers, interrupt handlers, and address-decoding logic for test-and-measurement modules. The 78 user I/Os match the VME D-size connector pin budget, and the 5.0V tolerance aligns with the VME 5V signaling specification. The FastTrack interconnect enables deterministic bus arbitration cycles critical for VME's 40 MB/s sustained throughput. The part's JTAG boundary-scan simplifies VXI card self-test diagnostics per IEEE 1149.5.
Recomendado
Glue-Logic Consolidation for Legacy ASICs
Designers frequently deployed the EPF8820ARI208-2N to replace 5-10 discrete 74-series TTL/CMOS glue-logic ICs with a single reconfigurable device, reducing PCB area, BOM cost, and power consumption. Typical applications included address decoding, wait-state generation, FIFO handshaking, and interrupt prioritization in VME/PCI/ISA systems. With 504 LEs available, the device handles dozens of discrete-equivalent functions while maintaining timing margin via the FastTrack continuous interconnect. Legacy designs continue to use these FLEX 8000 parts where modern Cyclone alternatives are not pin-compatible.

Notas de projeto
The EPF8820ARI208-2N requires 5.0V VCCINT (core) and a separate VCCIO (3.3V or 5.0V depending on I/O bank) with a 100-200 mA typical supply current. Decoupling requires 0.1 uF ceramic capacitors at every VCCINT/VCCIO pin and a bulk 22-47 uF tantalum or polymer capacitor at the supply rail entry point. Inrush current during configuration can spike to 500 mA; provision the regulator with adequate headroom.
Place the EPC configuration device within 50 mm of the FPGA's configuration pins (DCLK, DATA0, nCONFIG, nSTATUS, CONF_DONE) to minimize signal integrity issues. Use 4-layer PCB with dedicated ground and power planes. Route high-speed clock signals (GCLK1-3) with controlled impedance and matched lengths to avoid skew. Add series damping resistors (33 ohm) on clock nets if ringing is observed.
Do not leave MSEL pins floating - strap them to VCCINT or GND via 10 kohm resistors to define the configuration mode (typically MSEL[1:0]=00 for EPC2 passive-serial mode). The DEV_CLRn and DEV_OE pins, if unused, should be tied high via 10 kohm pull-ups. Failing to configure pull-ups properly can cause unexpected device reset or tri-state on power-up, leading to bus contention on shared I/O lines.
