EPF8820ARC208-4N Ringkasan

The Altera EPF8820ARC208-4N is a member of the FLEX 8000 family of CMOS Field Programmable Gate Arrays (FPGAs), offering 8,000 usable gates, 672 logic elements, and a maximum operating frequency of 125 MHz in a 208-pin Power Quad Flat Pack (RQFP/BFQFP) package with exposed thermal pad. The device is fabricated on a 0.42 µm CMOS process and supports configurable I/O voltages of 3.3 V or 5 V, providing 152 user I/O lines plus 4 dedicated input pins for clock and global control signals. The propagation delay through the logic array is 5.5 ns, suitable for glue-logic, bus-interface, and state-machine applications in industrial and commercial temperature grades.

An FPGA (Field Programmable Gate Array) is a programmable logic device that combines the high integration of a gate array with the field-programmability of a PLD. FPGAs occupy the middle of the programmable logic hierarchy between simple Complex PLDs (CPLDs) and large System-on-Cel (SoC) FPGAs; they are typically used for register-rich, high-gate-count glue logic, custom datapaths, and protocol bridges where low-to-moderate complexity is required but a CPLD does not provide enough logic capacity. The FLEX 8000 family specifically targets low-cost, high-volume designs with in-circuit reconfigurability (ICR) and SRAM-based configuration memory.

Key features of the EPF8820ARC208-4N include a 5 V core voltage (4.75 V to 5.25 V supply range), 5.5 ns pin-to-pin propagation delay, 125 MHz internal performance, fast continuous interconnect with predictable delay, and JTAG-compliant boundary-scan test support. The exposed thermal pad on the 208-RQFP package enables direct heatsinking for industrial temperature operation (-40 °C to +85 °C) and improves reliability in thermally constrained enclosures.

Architecturally, the EPF8820ARC208-4N consists of logic array blocks (LABs) containing 8 logic elements each, organized into rows and columns and interconnected by a continuous FastTrack routing network. Each logic element includes a 4-input look-up table (LUT), a programmable register, and a carry chain for arithmetic operations, enabling efficient implementation of counters, adders, and state machines. Embedded memory blocks and phase-locked loops (PLLs) are not present in this family - designers needing those should migrate to the FLEX 10K or Cyclone families.

Typical applications include industrial control glue logic, peripheral bus bridges (PCI, ISA, VME), telecommunications line-card interfaces, custom register and FIFO interfaces, and legacy system upgrades that require a 5 V tolerant programmable device. The wide I/O count (152 pins) makes it a fit for designs that need to replace multiple 74-series TTL packages.

Designers should note that the EPF8820ARC208-4N is a mature, obsolete-generation part. Long-term designs should plan for last-time-buy or migration to the Cyclone or MAX families, both of which offer pin-compatible footprints in selected packages. Decoupling the five 5 V supply pins with 0.1 µF X7R capacitors placed within 5 mm of each supply pin is essential for switching-noise immunity; the exposed thermal pad must be soldered to a copper pour of at least 1 square inch for industrial-temperature operation.
