EPF81188ARC240-2 - FLEX 8000 FPGA 12K Gates 240-RQFP | Altera
MPN: EPF81188ARC240-2 ✗ Cuối đờiEPF81188ARC240-2 Tóm tắt
What is a FLEX 8000 FPGA? The FLEX 8000 family is a register-rich CMOS programmable logic device (PLD) line introduced by Altera in the 1990s. FPGAs (Field-Programmable Gate Arrays) belong to the broader category of programmable logic devices, sitting hierarchically as: FPGA -> PLD -> logic IC -> integrated circuit -> semiconductor. The FLEX 8000 series provides in-circuit reconfigurability (ICR) through external configuration devices or intelligent controllers, and is fully compliant with the PCI Local Bus Specification from the Peripheral Component Interconnect Special Interest Group (PCI SIG), enabling direct interface to PCI bus systems without bridging logic.
Key features of the EPF81188ARC240-2 include 12,000 usable gates, 1,008 logic cells, 282 to 1,500 flip-flops depending on utilization, 184 maximum user I/O pins, and PCI-compliant I/O signalling. The device supports in-circuit reconfigurability, allowing field upgrades without removing the part from the board. Its 0.42 µm CMOS process provides mature, well-characterized silicon with predictable timing closure. The 240-pin RQFP package with exposed pad offers robust through-hole-style PCB mounting suitable for legacy industrial and telecom backplane designs.
The architecture combines a fine-grained logic element array with a continuous FastTrack interconnect routing fabric, providing predictable delay regardless of logic placement. The integrated PCI-compliant interface block supports 33 MHz PCI bus operation. Programming is performed through Altera's MAX+PLUS II development system, which supports VHDL, Verilog HDL, and waveform design entry, compilation, synthesis, simulation, and timing analysis.
Typical applications include PCI bus interface cards, telecommunications backplane glue logic, industrial control and factory automation controllers, legacy computing expansion peripherals, and avionics/military retrofits where 5 V tolerant PLDs with long-term availability are required. The wide logic capacity and abundant registers make it well suited to bus arbitration, protocol conversion, and state-machine-heavy designs.
When designing with this device, verify the configuration scheme (EPC configuration device or controller-based) and ensure decoupling capacitance meets the MAX+PLUS II power-budget guidelines. The exposed pad must be soldered to a thermal pad for reliable operation. Note that this device is a legacy 5 V part - confirm I/O compatibility with downstream 3.3 V logic before integration.

Ghi chú thiết kế
The EPF81188ARC240-2 operates from a 5 V supply typical of the FLEX 8000 family. Per the Altera FLEX 8000 datasheet, the device draws substantial inrush current during configuration - bulk decoupling should include 100 µF tantalum plus 0.1 µF ceramic per VCC pin pair. Use a low-impedance power plane rather than traces. Add a power-on reset supervisor to ensure nCONFIG is held low until VCC reaches stable regulation.
The 240-RQFP package with exposed pad requires the thermal pad to be soldered to a PCB copper pour for proper heat dissipation. Estimated: at 125 MHz toggle rate with 184 active I/O driving 50 pF loads, the device dissipates approximately 1.5-2.5 W. Use at least 2 square inches of 1 oz copper on top and bottom layers connected via thermal vias for reliable operation in industrial temperature ranges.
Route all FLEX 8000 I/O signals with controlled impedance (50 Ω microstrip or stripline) for signal integrity at 125 MHz. Keep configuration-related signals (nCONFIG, nSTATUS, CONF_DONE, MSEL0/MSEL1) away from high-speed switching nets. Provide a dedicated JTAG header (TMS, TCK, TDI, TDO, TRST) accessible for in-system programming via the ByteBlaster or MasterBlaster download cable.
Do not assume MAX+PLUS II projects are compatible with modern Quartus Prime - the FLEX 8000 family requires MAX+PLUS II legacy software. Ensure configuration mode pins (MSEL0, MSEL1) are correctly set for the chosen EPC device. Verify 5 V I/O tolerance matches downstream logic - FLEX 8000 outputs are 5 V TTL and may damage 3.3 V-only devices without level translation. Confirm package pinout against the datasheet, as FLEX 8000 family variants share the 240-pin RQFP but with different I/O assignments.
Separate analog/digital grounds are not required (this is a digital PLD), but use a single ground plane with split planes only under isolation-sensitive circuits. Place configuration EPC memory as close as possible to the FPGA's DATA, DCLK, and nCS pins - these are time-critical during configuration. Reserve a global clock input pin (CLK0 or CLK1) for the system clock and route it on the top layer with ground reference.
