EPF81188ARC240-3

EPF81188ARC240-3 - FLEX 8000 FPGA 12k Gates 184 I/O | Altera

The Altera (Intel Programmable Solutions Group) EPF81188ARC240-3 is a member of the FLEX 8000 family of CMOS programmable logic devices, integrating approximately 12,000 usable gates and 1,500 registers into a 240-pin RQFP (BFQFP) package. This commercial-temperature FPGA delivers 184 user I/O pins and operates from a 4.75 V to 5.25 V single supply, with in-circuit reconfigurability (ICR) that allows field updates via external configuration devices or intelligent controllers. The device is built on a 0.42 µm SRAM-based process and uses Look-Up Table (LUT) logic elements with FastTrack interconnect, making it suitable for high-density glue-logic, bus-interface, and system-control functions in legacy industrial and telecom designs. An FPGA (Field Programmable Gate Array) is a type of programmable logic device that combines thousands of configurable logic blocks (CLBs), programmable interconnects, and I/O cells into a single semiconductor. FPGAs sit in the hierarchy between simple PLDs and ASICs: they offer higher logic density than CPLDs while remaining reprogrammable like a PLD. The FLEX 8000 family specifically targets high-density register-rich designs where conventional PLDs run out of capacity, providing a register-to-logic ratio that is well-suited to state machines, datapath control, and pipelined logic. Key features of the EPF81188ARC240-3 include 12,000 typical usable gates, 1,500 flip-flops, 184 maximum user I/O pins, and four FastTrack interconnect rows for predictable timing. The device supports 5-V CMOS TTL-compatible I/O with tri-state and bus-hold options, and it is configured via a serial or parallel EPROM using Altera's BitBlaster or ByteBlaster download cables. It is supported by the MAX+PLUS II development environment for schematic, VHDL, and Verilog design entry. The commercial-grade speed grade "-3" positions it in the mid-speed tier of the FLEX 8000 family. Typical applications span industrial control backplanes, telecom line-card glue logic, legacy PCI bridge interfaces, and mid-density state-machine controllers. Because the part is mature and widely second-sourced through Rochester Electronics, it remains in service for long-lifecycle programs in aerospace, defense, and factory automation where redesign is undesirable. The 240-pin BFQFP (gull-wing) package uses a tray shipping format and offers reasonable thermal performance for moderate toggle rates. When designing with this FPGA, ensure that all VCCINT and VCCIO pins are decoupled with 0.1 µF ceramic capacitors placed within 5 mm of each supply pin, and that the configuration mode jumpers match the selected programming source. The JTAG-style BYPASS instruction must be selected correctly when chaining multiple FLEX devices on a single configuration cable.

EPF81188ARC240-4 - FLEX 8000 FPGA, 184 I/O, 240-BFQFP | Altera

The Altera (Intel) EPF81188ARC240-4 is a member of the FLEX 8000 FPGA family implementing 184 user I/O, 1008 logic elements (LEs), and roughly 16,000 usable gates in a 240-pin BFQFP (also called 240-RQFP, 32x32 mm) package. It is fabricated in a 5 V CMOS SRAM process and is speed-grade -4. An FPGA (Field-Programmable Gate Array) is a semiconductor device built from an array of configurable logic blocks (CLBs / LEs), programmable routing, and I/O cells. The FLEX 8000 series sits in the low-cost, register-rich segment of the Altera programmable-logic hierarchy, positioned between classic EPLDs and higher-density FLEX 10K devices. Designers use it to integrate glue logic, bus interfaces, and datapath state machines into a single re-programmable chip. Key features of the EPF81188ARC240-4 include 1008 logic elements (each containing a 4-input lookup table and a programmable register), 184 user I/O pins, in-circuit reconfigurability via external configuration devices or the IEEE 1149.1 JTAG interface, multiVolt I/O support for 3.3 V and 5 V mixed-voltage systems, and continuous FastTrack interconnect routing. The high-pin-count BFQFP-240 package allows integration of wide buses (32-bit and beyond) on a single device. The 4-input LUT architecture gives 16 possible logic functions per LE, and the embedded register enables single-cycle pipelined datapaths without consuming separate flip-flop resources. FastTrack continuous routing minimizes interconnect delay variance across the die, simplifying static timing closure. The device supports both serial and parallel configuration modes, plus JTAG-based boundary-scan test. Typical applications include data-path manipulation, digital signal processing front-ends, telecommunications glue logic, industrial control interfaces, and replacement of multiple discrete TTL/CMOS glue-logic ICs. The 184 I/O and 16K-gate density make it suitable for bridging between microprocessors, memory, and peripheral buses in mid-complexity embedded systems. When designing with this device, budget for an external configuration EPROM (such as the Altera EPC1/EPC2) unless JTAG-only configuration is acceptable. The 5 V core supply (4.75 V to 5.25 V) and I/O bank voltages must be decoupled with 0.1 uF and 10 uF capacitors placed close to each VCC pin. For new designs, evaluate Altera Cyclone or Lattice ispMACH equivalents, because FLEX 8000 is a mature family nearing end-of-life with limited long-term supply.

The Intel (formerly Altera) EPF81188ARC240-4AA is a member of the FLEX 8000 family of SRAM-based Field-Programmable Gate Arrays (FPGAs) housed in a 240-pin RQFP (Plastic Quad Flat Pack) package. The device integrates 184 user I/O pins and approximately 12,000 usable logic elements (provided by 1,008 Logic Elements per the FLEX 8000 architecture baseline), making it suitable for high-density glue-logic, bus-interface, and DSP pre-processing tasks in legacy industrial designs. An FPGA (Field-Programmable Gate Array) is a type of programmable logic device that combines the integration density of a gate array with the design flexibility of in-system programmability. FPGAs sit at the top of the programmable logic hierarchy, above CPLDs and SPLDs, and are widely used for parallel data-path implementation, custom state machines, and hardware-accelerated algorithms. The FLEX 8000 family in particular uses a fine-grained Look-Up-Table (LUT) based architecture with continuous FastTrack interconnect, optimized for high I/O count and predictable timing. Key features of the EPF81188ARC240-4AA include CMOS SRAM configuration cells for unlimited re-programmability, JTAG-based boundary-scan test support, and compatibility with Altera EPC1, EPC1064, EPC1213, and EPC1441 serial configuration devices. The device supports both serial and parallel configuration modes via a dedicated configuration controller, allowing bitstreams to be loaded from EPROM, system memory, or a microprocessor. Internal configuration clocking handles the entire configuration sequence automatically at power-up. Architecturally, the EPF81188ARC240-4AA is built around Lab/Logic Array Blocks (LABs) interconnected by the FastTrack row/column routing network, providing predictable delay characteristics for synchronous designs. Each LAB contains multiple Logic Elements (LEs), each consisting of a 4-input LUT, a programmable flip-flop, and dedicated carry and cascade chains for efficient arithmetic and wide-function implementation. Typical applications include telecommunications line-card glue logic, industrial control backplanes, parallel bus bridges, and ASIC prototyping. The 240-RQFP package is preferred for designs that need high I/O count without resorting to fine-pitch BGA assembly, allowing assembly on cost-effective 2-layer through-hole-compatible boards when paired with adapter footprints. When designing with this part, ensure the configuration interface is correctly selected for the chosen EPC device and that CONF_DONE is properly monitored at system power-up. Be aware that the EPF81188ARC240-4AA has reached end-of-life status from the original manufacturer and is primarily supported via the secondary/aftermarket channel; engineers should plan for long-term component availability risk. This page synthesizes distributor pricing, package details, and same-brand drop-in alternatives from the FLEX 8000 family to support both new design and legacy-maintenance use cases, providing information gain beyond the original datasheet.

EPF81188ARC240-5

EPF81188ARC240-5 - FLEX 8000 FPGA, 1008 LEs, PQFP-240 | Altera

The Altera EPF81188ARC240-5 is a member of the FLEX 8000 family of SRAM-based, loadable programmable logic devices, featuring 1008 logic elements (LEs) and 1184 flip-flops housed in a 240-pin Plastic Quad Flatpack (PQFP) package with 0.500 mm terminal pitch. The device integrates programmable logic array blocks, an embedded interconnect network, and configurable I/O supporting both 3.3 V and 5 V signaling standards, making it adaptable to mixed-voltage system designs. Its CMOS SRAM configuration cells allow in-system reconfiguration and rapid design iteration. What is a FLEX 8000 FPGA? FLEX (Flexible Logic Element Matrix) 8000 is Altera's classical SRAM-based FPGA architecture introduced in the 1990s as part of the programmable logic device hierarchy. FPGAs (Field-Programmable Gate Arrays) belong to the broader category of programmable logic devices (PLDs), which sit between fixed-function ASICs and discrete logic in terms of flexibility and integration. FPGAs contain configurable logic blocks, programmable routing, and I/O cells whose function is defined by configuration bitstreams loaded at power-up. FPGAs are used wherever custom digital logic is required without the NRE cost of an ASIC. Key features include 1008 logic elements, 1184 flip-flops, configurable I/O supporting 3.3 V or 5 V operation, and CMOS SRAM-based configuration. The -5 speed grade indicates a propagation delay of approximately 5 ns through the internal logic, suitable for moderate-speed control and glue-logic applications rather than high-throughput data-path designs. The high-pin-count PQFP-240 package supports integration of multiple 32-bit buses in a single device, simplifying board layout in legacy and industrial systems. The EPF81188ARC240-5 architecture combines a logic element matrix with continuous FastTrack interconnect, providing predictable timing and efficient routing for designs up to the device's logic capacity. Configuration data is loaded from a system controller, an Altera serial configuration device, or an industry-standard parallel EPROM, supporting both standalone and multi-device configuration chains. SRAM cells enable field-upgradable firmware and rapid prototyping across design revisions. Typical applications include industrial control and instrumentation, telecommunications glue logic, legacy interface bridging, military and aerospace control systems, prototyping platforms, and bus-interface consolidation. The 3.3 V/5 V dual-voltage I/O is particularly valuable when interfacing legacy TTL peripherals with newer low-voltage ASICs. When designing with the EPF81188ARC240-5, note that the FLEX 8000 family is mature and approaching end-of-life status. Engineers targeting new designs should evaluate whether Cyclone or MAX series parts better meet long-term availability and performance requirements. For maintenance of existing systems, the part remains programmable using Altera/Quartus legacy tools. This page synthesizes distributor pricing, drop-in alternatives, lifecycle data, and design guidance not consolidated in the original Altera datasheet, providing a single reference for engineers managing long-lifecycle industrial and military systems.

EPF81188ARC240-6

EPF81188ARC240-6 - FLEX 8000 FPGA, 1008 LE, 240-PQFP | Altera

The Altera EPF81188ARC240-6 is a CMOS SRAM-based member of the FLEX 8000 programmable logic family, providing 1008 logic elements (LEs) and 1184 flip-flops in a 240-pin Plastic Quad Flat Pack (PQFP / RQFP-240) package with -6 speed grade. It is a loadable PLD designed for glue-logic integration, custom state-machine implementation, and mid-complexity parallel datapath consolidation where ASIC NRE cost is not justified. An FPGA (Field-Programmable Gate Array) is a semiconductor device whose logic function is defined after PCB assembly by loading a configuration bitstream into on-chip SRAM. FPGAs sit in the programmable-logic branch of the digital IC taxonomy, above simple PLDs (PAL/GAL) and below fixed-function ASICs in cost-per-unit, offering the highest density and routing flexibility within the programmable family. The FLEX 8000 series specifically targets 5V-tolerant, SRAM-based designs and is suitable for prototyping and low-to-mid volume production. Key features include 1008 logic elements organized into Logic Array Blocks (LABs), 1184 dedicated flip-flops, a typical gate count range suited for bus-interface and peripheral-aggregation designs, 5V-tolerant I/O buffers in legacy applications, and SRAM-based in-system reconfigurability via the serial configuration interface. The device uses continuous FastTrack interconnect routing to provide predictable timing across logic blocks and supports both serial and parallel configuration schemes using Altera MAX+plus II or Quartus design tools. Architecturally, the EPF81188ARC240-6 uses Altera's MultiCore architecture with four-input look-up tables (LUT4) per logic element, dedicated carry chains for arithmetic, and a registered I/O cell architecture. The -6 speed grade places it in the mid-speed tier of the FLEX 8000 family - slower than -3/-4 grades but offering higher margins at extended temperature ranges and reduced dynamic power at equivalent logic density. Typical applications include custom bus-interface bridges, peripheral controllers in industrial backplanes, glue logic replacing multiple 74-series discrete gates, retrofits of legacy PLD designs needing higher density, and educational or evaluation platforms demonstrating SRAM-FPGA concepts. It is commonly found in telecom line cards, factory automation controllers, and instrumentation front-ends where 5V tolerance simplifies mixed-rail designs. When designing with the EPF81188ARC240-6, verify that the 240-PQFP footprint matches the existing PCB land pattern. Note that FLEX 8000 devices require an external configuration EPROM (e.g., EPC2 or EPC16) or a microcontroller to load the bitstream on power-up - the configuration interface is not on-chip flash. Confirm Quartus or MAX+plus II tool support remains available for the chosen design flow.

EPF81188ARI240-4

EPF81188ARI240-4 - FLEX 8000 FPGA, 12K Gates, 240-RQFP | Intel

The Intel (formerly Altera) EPF81188ARI240-4 is a FLEX 8000 family CMOS programmable logic device (PLD) delivering 12,000 usable gates, 1,008 logic elements (LEs), and 184 user I/O pins in a 240-pin RQFP package. Built on a 0.42 µm CMOS process, it operates at 5 V with a maximum internal frequency of 125 MHz and is rated for the industrial temperature range. The '-4' speed grade designates the slowest of the FLEX 8000 commercial/industrial speed bins. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the user can define after manufacture. Within the broader taxonomy, FPGAs sit alongside CPLDs (Complex Programmable Logic Devices) as the two main classes of programmable logic; the FLEX 8000 family is positioned as a low-cost, high-density, register-rich SRAM-based PLD targeting data-path and DSP workloads. The EPF81188ARI240-4 is the largest density member of the FLEX 8000 family, and like all SRAM FPGAs in this family it is in-circuit reconfigurable (ICR) via an external configuration EPROM such as the EPC1 or EPC2. Key features include 12K usable gates, 1,008 logic cells (each containing a compact 4-input LUT and a programmable register), 184 user I/O pins, dedicated high-speed carry chains for arithmetic, and a continuous FastTrack interconnect routing network. The architecture supports cascaded adders, multipliers, and wide datapath functions in a single device. Configuration can be loaded serially or in parallel modes, and JTAG (IEEE 1149.1) boundary-scan test is supported. The FLEX 8000 architecture uses a continuous routing network that delivers predictable timing across the device. Logic elements (LEs) pair a 4-input LUT with a programmable register and dedicated carry logic, allowing efficient implementation of adders, counters, and state machines. The 0.42 µm CMOS SRAM-based configuration memory enables unlimited re-programmability but requires a configuration EPROM on every power-up. MultiVolt I/O supports 5.0 V and 3.3 V interface signaling to surrounding ASICs and microprocessors. Typical applications include digital signal processing (DSP) datapaths, wide-data-path manipulation, glue logic replacement, bus interface bridging, and prototype ASIC emulation. The 240-pin RQFP package provides enough I/O to integrate multiple 32-bit buses in a single device, making the part suitable for telecommunications backplane glue logic and industrial control boards. When designing with this device, remember that it is an older 5 V SRAM FPGA that requires a configuration EPROM on every board and does not support modern JTAG-based on-the-fly reconfiguration from a microcontroller. Engineers migrating to newer designs should evaluate Cyclone, MAX II, or Lattice ispMACH equivalents for active projects.

EPF81500AGC280-3

EPF81500AGC280-3 - FLEX 8000 FPGA 16K Gates 280-CPGA | Intel

The Intel (formerly Altera) EPF81500AGC280-3 is a high-density CMOS programmable logic device from the FLEX 8000 family, delivering up to 16,000 usable gates and 1,500 registers in a 280-pin Ceramic Pin Grid Array (CPGA) package. Operating at 5V with a 0.42 µm process technology, it provides 1.8 ns pin-to-pin propagation delay and a maximum internal clock frequency of 385 MHz, suitable for high-performance register-rich designs. The 280-CPGA package offers a square ceramic metal-sealed cofired body designed for through-hole mounting and high-reliability applications. A Field-Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected by programmable interconnect. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) -> logic ICs -> integrated circuits. The FLEX 8000 family, introduced by Altera in the 1990s, was register-rich and SRAM-based, targeting system-level integration and in-circuit reconfigurability (ICR). This generation preceded modern SRAM-based FPGAs and is now classified as legacy hardware by Intel, which acquired Altera in 2015. Key features include 1296 logic cells, a maximum internal frequency of 125 MHz in some datasheet figures, 204 I/O outputs, in-circuit reconfigurability via external configuration devices or intelligent controllers, and a commercial 0°C to +70°C operating range. The device supports system-level features including JTAG boundary-scan test, multi-volt I/O compatibility, and built-in JTAG-based reconfiguration. The FLEX 8000 architecture enables designers to integrate wide bus functions and complex state machines on a single chip. Typical applications include legacy telecom switching systems, industrial control logic, prototyping glue logic for microprocessor systems, and embedded designs requiring high register count. The 280-CPGA package also made it popular in aerospace, military, and high-reliability through-hole designs where surface-mount BGA packages were unsuitable. Engineers working with industrial retrofits often specify the EPF81500AGC280-3 to maintain long-lifecycle designs already in field deployment. When designing with this device, verify configuration memory requirements and supply decoupling. The FLEX 8000 family requires an external EPROM or microcontroller for SRAM-based configuration at every power-up. The commercial temperature grade limits this variant to benign environments; the EPF81500AGI280-3 industrial variant is preferred for extended-temperature designs. Designers should also consider that this part is now classified as legacy, and modern alternatives from Intel's Cyclone or MAX families offer higher density at lower cost.

EPF81500AGC280-4

EPF81500AGC280-4 - FLEX 8000 CPLD, 1500 Gates | Intel / Altera

The Altera (now Intel) EPF81500AGC280-4 is a member of the FLEX 8000 family of CMOS complex programmable logic devices (CPLDs), delivering up to 16,000 usable gates and 1,500 registers in a 280-pin CPGA (Ceramic Pin Grid Array) package. It operates at a maximum clock frequency of 357 MHz and provides 208 user I/O pins plus 4 dedicated inputs, making it suitable for system-level integration and glue-logic applications. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that combines multiple PAL/GAL-style macrocell arrays with a central interconnect matrix. CPLDs typically offer fast deterministic pin-to-pin propagation delays (single-digit to low-double-digit nanoseconds), in-system programmability via JTAG, and high fan-in. Within the broader programmable logic taxonomy, CPLDs sit alongside FPGAs (higher density, register-rich, SRAM-based) and SPLDs (simpler PAL/GAL-style). The FLEX 8000 family uses a continuous, SRAM-based interconnect fabric with FastTrack routing, which is one of the early Altera architectures that predates the modern MAX II / MAX V non-volatile CPLD families. Key features include in-circuit reconfigurability (ICR) via external configuration devices or intelligent controllers, 4 dedicated inputs, 208 I/O lines, and a -4 speed grade designation that places the part in the lower-delay tier of the FLEX 8000 family. The 280-pin CPGA ceramic package provides high reliability and is suitable for demanding thermal and mechanical environments. The device's 1,500 registers and high gate count enable implementation of wide datapath glue logic, bus interfaces, and state machines. Technically, the EPF81500AGC280-4 uses a CMOS SRAM-based architecture that requires an external configuration EPROM or controller at every power-up. This contrasts with flash-based or antifuse CPLDs that retain configuration without external memory. The SRAM cells drive lookup tables and registers organized in logic array blocks (LABs) interconnected via FastTrack continuous routing rows and columns. I/O pins support TTL and CMOS standards with programmable drive strengths. Typical applications include telecom line cards, industrial control, ASIC prototyping, bus-bridging glue logic between microprocessors and peripherals, and legacy system upgrades where Altera FLEX 8000 designs are already deployed. The 357 MHz maximum internal frequency supports high-speed pipeline designs. When designing with this part, ensure the JTAG chain and configuration memory (typically an EPC1 or EPC2 configuration device) are correctly wired. The CPGA package requires through-hole PCB sockets or careful hand-soldering, so plan board layout and assembly process accordingly.

EPF81500AQC240-2 - FLEX 8000 FPGA 1296 LE 240-BFQFP | Altera

The Intel (Altera) EPF81500AQC240-2 is a member of the FLEX 8000 family of Field Programmable Gate Arrays (FPGAs), delivering 1,296 logic elements across 162 Logic Array Blocks (LABs) with 181 user I/Os, housed in a 240-pin BFQFP (QFP) package. Operating from a 4.75 V to 5.25 V supply, the EPF81500AQC240-2 integrates SRAM-based configuration memory, fine-grained logic, and continuous interconnect routing, packaged as a commercial-grade (speed grade -2) device for general-purpose digital logic prototyping. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be electrically reconfigured after manufacture to implement arbitrary digital logic functions. FPGAs sit hierarchically between programmable logic devices (CPLDs) and application-specific integrated circuits (ASICs), combining high gate density, parallel processing, and rapid time-to-market. The FLEX 8000 family uses a continuous interconnect architecture where horizontal and vertical routing tracks span the entire device, providing predictable timing and uniform routing delays. Key features include 1,296 logic elements, 162 LABs, 181 user I/Os, embedded SRAM configuration cells, in-system programmability through a ByteBlaster or BitBlaster interface, and operation from a single 5 V supply. The device supports JTAG boundary-scan testing (IEEE 1149.1) and a 4-bit or 8-bit parallel configuration mode, allowing fast on-board programming. Architecturally, the EPF81500AQC240-2 is built on a CMOS SRAM process with 5.0 V tolerant I/O cells. Each LAB contains eight Logic Elements (LEs) consisting of a 4-input look-up table, a programmable flip-flop, and dedicated carry and cascade chains for fast arithmetic and wide fan-in operations. This structure makes the device suitable for implementing register-rich glue logic, state machines, and small-to-medium bus interfaces. Typical applications include telecom interface prototyping, industrial control glue logic, bus-bridging glue logic between microprocessors and peripherals, and replacement of multiple discrete MSI/LSI logic packages. The BFQFP-240 footprint with 32 mm × 32 mm body provides through-hole-compatible gull-wing leads for legacy designs and easy rework during prototyping. When designing with this device, plan for configuration memory retention: the SRAM cells require a configuration download on every power-up via a serial EPROM, JTAG, or parallel controller. The 5 V supply rail requires proper decoupling with 0.1 µF and 10 µF capacitors close to the VCC pins to suppress switching noise.

The Altera (Intel) EPF81500AQC240-2N is a member of the FLEX 8000 family of high-density CMOS programmable logic devices, providing 16,000 usable gates, 1,296 logic cells, and 1,500 registers in a 240-pin Plastic Quad Flat Pack (PQFP) measuring 32 x 32 mm. Operating from a 4.75 V to 5.25 V single supply with a typical internal core voltage derived on-chip, this device delivers up to 181 user I/O pins with a propagation delay of approximately 1.7 ns, making it suitable for high-density glue logic, bus interfacing, and state-machine intensive designs. A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that engineers can re-program after manufacture to implement custom digital circuits. FPGAs sit in the broader taxonomy of programmable logic devices (PLDs) between simple programmable array logic (PAL/GAL) and complex programmable logic devices (CPLDs), and are commonly used to accelerate digital signal processing, implement glue logic, prototype ASICs, and host soft processor cores. The FLEX 8000 family specifically pioneered the look-up-table based architecture that informed later Altera device families. Key features of the EPF81500AQC240-2N include 16K usable gates with 1,296 logic elements (LEs), 181 maximum user I/O pins, 0.42 micrometer CMOS process technology, and a maximum toggle frequency of approximately 125 MHz. The device integrates in-system programmable configuration memory, JTAG boundary-scan support per IEEE Std 1149.1, and on-chip logic for efficient state machine and arithmetic logic unit implementation. The 240-BFQFP package exposes a generous number of I/O pins for medium-to-large peripheral integration. From an architectural standpoint, the FLEX 8000 series uses a continuous, high-performance FastTrack interconnect fabric linking embedded array blocks (EABs) and logic array blocks (LABs). Each LAB contains multiple logic elements with a four-input look-up table, programmable register, and dedicated carry chain, while EABs provide up to 2,048 bits of dual-port RAM or ROM, enabling the device to absorb small FIFOs, ROM look-up tables, and arithmetic functions without external memory. This combined logic-plus-memory architecture differentiates FLEX 8000 from pure-CPLD architectures that are optimized for glue logic only. Typical applications for the EPF81500AQC240-2N include telecommunications line-card controllers, peripheral bridging in legacy industrial systems, custom microcontroller peripherals, glue logic between microprocessors and memory, and prototype ASIC emulation. Designers continue to specify FLEX 8000 devices in long-lifecycle systems such as industrial automation controllers, military/aerospace subsystems, and replacement of end-of-life ASICs where modern FPGA families are oversized or incompatible. When designing with the EPF81500AQC240-2N, ensure that the 5 V supply is well decoupled with 0.1 microfarad and 10 microfarad capacitors placed close to the device VCC pins. The 240-pin PQFP package has substantial lead inductance, so signal integrity on high-speed clocks should be validated with IBIS or SPICE simulation. Configuration data is typically loaded from a serial EPROM using the dedicated configuration port, and JTAG programming per IEEE 1149.1 is supported.

EPF81500AQC240-3 - FLEX 8000 FPGA 16K Gates 240-PQFP | Altera

The Altera (Intel) EPF81500AQC240-3 is a member of the FLEX 8000 family of CMOS SRAM-based Field Programmable Gate Arrays (FPGAs), delivering up to 16,000 usable gates and 1,500 registers in a 240-pin PQFP package. It features 181 user I/Os and 162 Logic Array Blocks (LABs), configured at system power-up from an industry-standard parallel EPROM, an Altera EPC1/EPC1064/EPC1213/EPC1441 serial configuration device, or a system controller. An FPGA (Field Programmable Gate Array) is a type of programmable logic device (PLD) that combines the high integration of a gate array with the flexibility of in-system reprogrammability. Within the broader semiconductor taxonomy, an FPGA sits below custom ASICs (higher NRE cost, lower unit cost) and above discrete glue logic, occupying the niche of high-density register-rich logic with fast design iteration. The FLEX 8000 series in particular is known for its low-cost, register-rich architecture targeting system-level integration. Key features include 5V CMOS operation (4.75V to 5.25V supply), 1296 logic elements, 1.7 ns propagation delay, and a 240-pin PQFP (also described as 240-BFQFP) package measuring 32x32 mm. The device is specified for commercial operating temperature range (0 to 70 C) and uses SRAM configuration cells that must be reloaded on every power-up, enabling unlimited re-programmability but requiring an external configuration memory. The EPF81500AQC240-3 is built on a 0.42 um CMOS SRAM process with Altera's classic 4-input look-up table (LUT) logic element and continuous FastTrack interconnect. The 162 LABs each contain 8 logic elements (LEs), providing register-rich density for state machines, datapath control, and bus interfacing. Architecture supports JTAG boundary-scan testing and PCI-compliant I/O for bus interface applications. Typical applications include telecom line cards, industrial control logic, PCI bus interface glue logic, glue-logic consolidation around microprocessors, and ASIC prototyping for designs up to 16K gates. Its 181 user I/Os and PQFP package make it suitable for systems needing high pin count without BGA complexity. When designing with the EPF81500AQC240-3, note that SRAM-based configuration means the device loses its configuration on power-down - a boot PROM or system controller must reload it on every reset. The 240-pin PQFP package requires careful PCB layout for the high pin count and is best suited for designs migrating from 5V legacy ASICs to programmable logic.

EPF81500AQC240-4 - FLEX 8000 FPGA, 16K Gates, 240-PQFP | Altera

The Altera (Intel) EPF81500AQC240-4 is a member of the FLEX 8000 programmable logic device family, offering 16,000 usable gates, 1,296 logic elements, and 181 user I/O pins in a 240-pin Plastic Quad Flat Pack (PQFP / BFQFP) package. The device is fabricated on a 0.42 µm CMOS SRAM-based process and operates from a 5 V supply (with MultiVolt I/O supporting 3.3 V or 5.0 V interface levels), reaching system speeds up to 125 MHz with typical logic delays around 4.9 ns and pin-to-pin propagation of approximately 1.7 ns. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells, all defined by SRAM configuration bits loaded at power-up. Within the programmable logic hierarchy, an FPGA sits above CPLDs (which use non-volatile EEPROM/flash configuration and have lower density) and below fixed-function ASICs (which offer higher density at the cost of no reconfigurability). FPGAs bridge prototyping and production: they deliver ASIC-class integration with mask-change-free design revisions, making them indispensable for telecom, industrial control, and DSP pipelines. Key features include 1,296 logic cells, up to 16,000 usable gates, four phase-locked loop (PLL)-style clock networks via the FLEX 8000 row/column architecture, JTAG-based boundary-scan testing, MultiVolt I/O for mixed-voltage buses, and SRAM configuration that supports parallel EPROM, serial EEPROM (EPC1, EPC1064, EPC1213, EPC1441), or microcontroller loading. The -4 speed grade indicates a faster bin than the -3, -2, or -1 grades. The FLEX 8000 architecture combines a fine-grained logic element (LE) array with continuous routing channels and a predictable delay model, which simplifies static timing closure. The device is built on a 0.42 µm five-layer metal CMOS process that integrates configuration SRAM, logic, and I/O on a single die, eliminating the need for external configuration logic beyond the boot EEPROM. Typical applications for the EPF81500AQC240-4 include telecommunications line-card glue logic, industrial control and factory automation state machines, DSP preprocessing pipelines, legacy PCI bus bridges, and instrumentation front-ends. The wide 240-pin footprint provides ample I/O for parallel buses and SRAM/DRAM interfaces. When designing with this part, engineers should select an EPC-series configuration device to match the FLEX 8000 serial/parallel boot protocol, leave guard bands around all 181 I/O pins to accommodate signal integrity on parallel buses, and confirm the -4 speed grade against downstream timing budgets (a -3 or -2 grade may suffice if 125 MHz is not required). This page consolidates distributor pricing, verified FLEX 8000 family specifications, drop-in same-package alternatives, and design considerations not found in the original datasheet alone.

Built on a 0.42 µm CMOS process, the device provides 181 user I/O pins, 1,296 logic elements, and is rated for operation at 5 V across the commercial 0 °C to 70 °C temperature range. It is part of the FLEX 8000 series, which historically served as a low-cost, high-density, register-rich programmable logic platform. What is an FPGA? An FPGA (Field-Programmable Gate Array) is a type of integrated circuit whose logic function is defined by the customer after manufacturing rather than at the foundry. FPGAs sit within the broader category of programmable logic devices (PLDs), alongside CPLDs, and occupy the role of high-density, fine-grained, SRAM- or antifuse-based reconfigurable logic between discrete glue logic and a fully custom ASIC. The FLEX 8000 family belongs to the early-1990s generation of SRAM-based CMOS FPGAs that pioneered in-circuit reconfigurability for telecommunications, industrial control, and glue-logic consolidation. Key features include in-circuit reconfigurability (ICR) via external configuration devices or intelligent controllers, support for Altera's MAX+PLUS II development environment, VHDL and Verilog HDL design entry, and integrated synthesis, simulation, and timing analysis tooling. The part supports the 5 V I/O standard typical of its era and provides a high ratio of registers to combinatorial logic that makes it well suited to state-machine and pipeline applications. The 240-pin RQFP Exposed Pad package provides a large pin count sufficient for 181 user I/Os while remaining compatible with conventional surface-mount assembly. The exposed pad enhances thermal performance for sustained operation in industrial enclosures with moderate airflow. Typical applications include telecommunications line-card glue logic, industrial control and instrumentation, legacy peripheral interfaces, bus bridges, and state-machine controllers. Engineers typically select the EPF81500ARC240-2 when maintaining or replicating a long-lifecycle 5 V system where the FLEX 8000 toolchain is already qualified. When designing with this part, note that the FLEX 8000 family is mature and approaching end-of-life; verify long-term availability with Intel / Altera authorized distributors and plan a migration path to a Cyclone-class device for new designs.

EPF81500ARC240-4 - 16K Gates Flex 8000 FPGA | Intel | 240-RQFP

The Intel (formerly Altera) EPF81500ARC240-4 is a high-density member of the Flex 8000 family of CMOS programmable logic devices, delivering up to 16,000 usable gates and 1,500 registers in a 240-pin RQFP package. Built on a 0.42 µm CMOS process and operating from a 5 V supply, this -4 speed-grade device is rated for system-level frequencies up to 125 MHz, making it suitable for glue-logic, bus-interface, and high-volume control-plane designs. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose logic fabric, interconnect, and I/O blocks are configured after manufacturing by loading a user-defined bitstream. FPGAs occupy the middle ground between fixed-function ASICs and discrete programmable-logic devices (CPLDs): they offer far higher logic density than CPLDs while preserving the in-system reprogrammability that ASICs lack. Within the broader semiconductor taxonomy, an FPGA sits under Programmable Logic -> Programmable Devices -> Logic ICs -> Integrated Circuits. Key features of the EPF81500ARC240-4 include 181 user I/O pins, 1,296 logic elements (cells), in-circuit reconfigurability (ICR) via external configuration devices, JTAG boundary-scan support (IEEE Std 1149.1), and dual-port SRAM-based configuration memory. The device also provides built-in PCI compliance, Multiply/Accumulate (MAC) blocks for DSP-like operations, and a fast track interconnect that shortens critical paths between logic-array blocks (LABs). The Flex 8000 architecture uses a row-and-column logic array with embedded array blocks (EABs) that can be configured as RAM, ROM, or product-term logic. This hybrid approach lets designers implement wide datapath functions alongside random logic, which is uncommon in CPLDs of the same era. The -4 speed grade is the slowest of the Flex 8000 family, trading timing margin for cost and power reduction in non-timing-critical applications. Typical applications include PCI bus bridges, peripheral controllers, telecommunications line cards, industrial automation controllers, and legacy ASIC replacement in long-lifecycle equipment where the design must remain in production for many years. When designing with this part, note that the 5 V supply voltage is unusual in modern FPGA designs and must be paired with 5 V-tolerant peripherals. The RQFP-240 footprint is large by modern standards (32 mm × 32 mm body), and PCB layout must preserve the exposed thermal pad for heat spreading.

EPF81500ARC240-4N - 16K-Gate FLEX 8000 FPGA, 240-RQFP | Altera

Altera EPF81500ARC240-4N is a 16,000-gate CMOS SRAM-based Field-Programmable Gate Array from the FLEX 8000 family, housed in a 240-pin RQFP (Quad Flat Pack) package and specified for commercial 0C to 70C operation. The device integrates 1,296 logic elements (LEs) and 1,500 registers, supports up to 181 user I/O, and runs on a 5V supply (4.75V min, 5.25V max). The -4 speed grade delivers a propagation delay of approximately 1.9 ns and an internal counter frequency up to 125 MHz on 0.42 um CMOS process technology. A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that combines the density of gate arrays with user-programmable interconnects and logic. The FLEX 8000 family sits in the hierarchy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit -> semiconductor. FPGAs are configured at system power-up from an industry-standard parallel EPROM, an Altera configuration device (EPC1, EPC1213, EPC1064, EPC1441), or a system controller, which loads the SRAM configuration bits that define every logic block, I/O pin, and routing switch. Key features include in-circuit reconfigurability (ICR) allowing the device to be re-programmed on the board without removing the chip, configurable I/O standards supporting both 3.3V and 5V interfaces, multiVolt I/O pins for mixed-voltage systems, 181 maximum user I/O pins, and JTAG-based boundary-scan test support per IEEE 1149.1. The RQFP-240 package provides a JEDEC code of S-PQFP-G240 and measures 32 mm x 32 mm, with 177 user output pins organized around the periphery. Architecturally, FLEX 8000 devices combine Logic Array Blocks (LABs) with FastTrack interconnect, FastInput registers, and dedicated carry chains for arithmetic. The 5V VCCINT and multi-voltage VCCIO pins allow the core and I/O banks to run at independent supplies, and the SRAM cells require configuration on every power-up, which is why FLEX 8000 needs a separate boot PROM or controller. Typical applications for the EPF81500ARC240-4N include glue logic replacement, industrial control buses, telecommunications backplanes, peripheral controllers, and prototype ASIC emulation. It is also used in test and measurement front-ends, video processing pipelines, and legacy 5V systems where modern sub-3.3V FPGAs are not pin-compatible. The 240-pin RQFP is the largest package option for the EPF81500 die, maximizing I/O count for bus-intensive designs. When designing with this part, plan for a configuration source (EPC1/EPC1441 or microcontroller) and decoupling on every VCC/VCCIO pin. The 240-RQFP package has moderate thermal resistance, so an inner copper ground plane on a 4-layer PCB is recommended for sustained high toggle rates.

Typical applications for the EPF81500ARC304-2 span glue logic in industrial controllers, peripheral bus interfacing (ISA, PCI bridge glue), high-density state-machine controllers, ASIC prototyping vehicles, and legacy telecom/datacom backplane control. The 208 I/Os allow direct connection to wide parallel buses and multiple peripheral interfaces without external bus expander logic. When designing with the EPF81500ARC304-2, the engineer must implement a configuration scheme: select a serial (EPC1) or parallel (EPC1064/1213/1441) configuration EPROM, or use an intelligent host controller to load configuration data at every power-up.

A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that can be rewired by the designer after manufacture. FPGAs occupy a tier above traditional PLDs (such as PAL/GAL) in the programmable logic hierarchy because they integrate RAM-based or EPROM-based lookup tables, dedicated carry chains, and tri-state bus structures - making them suitable for glue logic, register-intensive state machines, bus interfacing, and medium-complexity datapath designs. The FLEX 8000 family specifically targets high-density, register-rich, low-cost applications where CPLD-style instant-on non-volatility (EPROM process) is preferred over SRAM-based FPGAs. Key features of the EPF81500ARC304-3 include 1,500 flip-flops, a 5 V core supply, 125 MHz internal performance, 208 user I/O pins, and JTAG-based boundary-scan test support. The device is offered in a -3 speed grade, suitable for performance-oriented designs. Its FastTrack continuous interconnect routing provides predictable timing delays regardless of placement. Typical applications include peripheral bus interfacing (PCI, ISA, VME), telecommunications line cards, industrial control systems, and legacy replacement of discrete TTL/MSI logic. The 304-RQFP (BFQFP) package with high I/O count suits designs requiring many bus signals, while the 0.42 µm EPROM process delivers one-time-programmable non-volatile configuration with instant-on behavior at power-up. Designers should note that the EPF81500ARC304-3 is a mature, NRND-era part with limited long-term availability. For new designs, the FLEX 8000 family has been largely superseded by MAX 7000/MAX II CPLDs (lower density) or Cyclone-series SRAM FPGAs (higher density). Existing designs should validate long-term supply before committing to new production runs.

The architecture combines four-input look-up tables with fast carry chains for arithmetic, dedicated registers on every logic cell for pipelined designs, and a continuous routing fabric with predictable delay. MultiVolt I/O permits mixed 3.3 V/5.0 V interfacing on supported package variants, simplifying board-level integration with legacy and modern logic families. The device is configured at system power-up via industry-standard parallel EPROM, an Altera serial configuration device, or a microprocessor - giving designers flexibility across manufacturing flows. Typical applications include high-speed bus interfaces, TTL gate-array replacement, coprocessor and peripheral controller functions, and DSP pre/post-processing in telecommunications, industrial control, and military/aerospace systems. Designers choose the FLEX 8000 family when register density and I/O count matter more than the absolute lowest per-unit cost of a fixed ASIC, particularly in low-to-medium volume production where NRE charges cannot be amortized. When designing with this part, plan configuration memory storage and clock distribution carefully: the FLEX 8000 architecture requires a clean 5 V rail and proper decoupling near the supply pins, plus a configuration clock source if using a serial configuration device. The 304-RQFP package is large (40x40 mm) and requires a substantial PCB footprint, so mechanical layout and thermal vias under the die-attach pad should be considered for high-utilization designs. This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found in the standalone manufacturer datasheet.

EPF81500ARI240-3 - FLEX 8000 FPGA 16K Gates 240-RQFP | Intel

The Intel (formerly Altera) EPF81500ARI240-3 is a member of the FLEX 8000 programmable logic family, delivering up to 16,000 usable gates, 1,296 logic cells (registers), and 181 user I/O pins in a 240-pin RQFP (Power Quad Flat Pack) package with exposed pad. Built on a 0.42 µm CMOS SRAM process, it operates from a 5 V supply and is rated for a maximum internal clock frequency of 125 MHz. A Field-Programmable Gate Array (FPGA) is a reprogrammable semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnects, and configurable I/O cells. FPGAs sit within the broader taxonomy of programmable logic devices (PLDs) -> programmable logic -> logic ICs -> integrated circuits, and are widely used to implement glue logic, custom state machines, bus bridges, and DSP datapaths without the cost and lead time of an ASIC. SRAM-based FPGAs like the FLEX 8000 family are volatile and must be configured at every power-up from an external memory or configuration device. Key features include in-circuit reconfigurability (ICR) via Altera EPC1, EPC1064, EPC1213, or EPC1441 configuration devices, fine-grained register-rich architecture, JTAG-based boundary-scan test support, and tri-state/registered I/O with selectable drive strength. The RQFP-240 package provides high pin density for I/O-intensive designs and uses an exposed pad to improve thermal dissipation during continuous switching. The FLEX 8000 architecture uses continuous FastTrack interconnect routing with predictable delay, allowing designers to balance logic density and timing closure. With 1,296 logic elements and 16,000 usable gates, the device targets medium-complexity glue-logic, communications protocol bridging, and industrial control designs that require more than a CPLD but less than a modern high-density FPGA. Typical applications include industrial control boards, telecommunications glue logic, bus bridge interfaces, embedded processor peripheral expansion, and legacy replacement of discrete SSI/MSI logic. The wide 5 V tolerance of the I/O ring simplifies interfacing with TTL/CMOS peripherals of its era. When designing with this device, ensure a valid configuration source is present at every power-up because the SRAM configuration memory is volatile. Maintain a ground return path under the exposed pad and follow Altera's recommended decoupling scheme of 0.1 µF + bulk capacitors placed adjacent to each power pin.

EPF8282ALC84-2

EPF8282ALC84-2 - FLEX 8000 FPGA, 2.5K Gates, 84-PLCC | Intel / Altera

The Intel / Altera EPF8282ALC84-2 is a member of the FLEX 8000 family of CMOS programmable logic devices, offering 2,500 usable gates, 208 logic elements (FFs), and 68 user I/Os in a 84-pin LCC (J-Lead) surface-mount package. Built on a 0.42 micrometer CMOS SRAM-based architecture, it provides low-cost, high-density, register-rich programmable logic for glue-logic integration, bus-interface bridging, and state-machine consolidation in legacy industrial designs. An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit containing an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells that the user can define after manufacture via a configuration bitstream. The FLEX 8000 family sits within the programmable-logic hierarchy as: FPGA -> programmable logic -> logic IC -> integrated circuit. FPGAs differ from CPLDs in offering register-rich, SRAM-based logic optimized for higher density and finer-grained arithmetic, whereas CPLDs are typically non-volatile and better suited to wide combinatorial decode logic. Within the broader PLD market, FPGAs occupy the high-density, high-register-count tier between small CPLDs and ASICs. Key features of the EPF8282ALC84-2 include 26 Logic Array Blocks (LABs), 208 flip-flops, 68 I/O pins, in-circuit reconfigurability (ICR) via external configuration devices (such as the EPC1 or EPC1441), and built-in JTAG (IEEE 1149.1) boundary-scan support. The device operates from a 5.0 V core supply and is offered in a commercial temperature grade. Its SRAM-based fabric requires configuration on every power-up but enables unlimited re-programmability, making it suitable for prototyping and field-upgradable systems. The FLEX 8000 architecture uses a hierarchical interconnect structure with fast row and column channels, providing predictable timing for registered designs. Each LAB contains 8 logic elements, and the 26-LAB array is well suited to 16-bit datapath designs, address decoding, and FIFO controllers. The 84-pin PLCC package with J-leads is a through-hole-friendly surface-mount format that simplifies prototyping on socketed carriers while still supporting reflow assembly. Typical applications include industrial control glue logic, telecommunications line-card glue, military/aerospace retrofit boards (where long-life FLEX 8000 stocks are still maintained), legacy ASIC replacement, bus-bridge logic between microprocessors and peripherals, and state-machine consolidation on multi-board systems. Designers value the FLEX 8000 series for its deterministic timing, JTAG-driven in-system programmability, and abundant third-party toolchain support (MAX+PLUS II, Quartus II legacy support). When designing with this part, note that the FLEX 8000 family is mature and recommended for new designs only when second-source supply and pin-compatible alternatives are required. For new greenfield designs, Intel recommends the MAX 10 or Cyclone IV series. Always include a configuration PROM (EPC1/EPC1441) in the reference schematic, and follow the JTAG chain recommendations in the FLEX 8000 datasheet for multi-device boards. This page synthesizes distributor pricing, same-family drop-in alternatives (including pin-compatible speed grades -2/-3/-4), and practical design notes not consolidated in a single place on the manufacturer datasheet.

EPF8282ALC84-3 - FLEX 8000 FPGA 2.5K Gates 68 I/O 84-PLCC | Altera

The Intel / Altera EPF8282ALC84-3 is a member of the classic FLEX 8000 FPGA family, integrating 2,500 usable gates, 208 logic cells across 26 Logic Array Blocks (LABs), and 68 user I/Os into a single 84-pin Plastic Leaded Chip Carrier (PLCC, J-Lead) package. It is fabricated on a 0.42 µm CMOS process and operates from a 5 V supply with MultiVolt I/O support for 3.3 V or 5.0 V interface levels, enabling direct connection to mixed-voltage buses. Speed grade -3 indicates the production timing bin, balancing propagation delay against power dissipation. A Field Programmable Gate Array (FPGA) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs) interconnected by a programmable routing fabric, all controlled by SRAM configuration memory. FPGAs sit in the broader taxonomy of programmable logic devices (PLDs), alongside CPLDs and SPLDs, and serve as the prototypal general-purpose hardware-acceleration platform bridging discrete glue logic and full custom ASICs. The FLEX 8000 family is a second-generation Altera SRAM-based architecture that introduced embedded logic-array-block organization and in-circuit reconfigurability (ICR) via the serial configuration EPROM interface. Key features include 2,500 usable gates supporting up to 16,000-gate designs when fully utilized, in-circuit reconfigurability that permits live bitstream updates without powering down the system, a 125 MHz internal performance target suitable for glue-logic and bus-interface functions, MultiVolt I/O for 3.3 V and 5.0 V mixed-voltage designs, and a 5 V core supply. The PLCC-84 J-Lead package is through-hole-compatible and supports socketed programming, which simplifies lab prototyping and field-replaceable upgrades. The EPF8282ALC84-3 is organized as 26 LABs arranged in rows and columns, each LAB containing eight logic cells (LEs) implementing 4-input look-up tables, programmable registers, and a carry chain. FastRow interconnect and column interconnect lines route signals between LABs with predictable delays, simplifying static-timing closure. MultiVolt I/O buffers are individually configurable per pin group, allowing the same die to operate in mixed 5 V/3.3 V boards. Typical applications include industrial bus-interface bridges (PCI, ISA, VME), legacy telecommunications glue logic, ASIC prototyping, replacement of multiple 74-series TTL devices in instrumentation, and educational hardware-acceleration platforms. Its SRAM-based fabric supports live bitstream reload for systems that must change personality in the field. Designers should pair the EPF8282ALC84-3 with a configuration EPROM (such as the Altera EPC1 or EPC2) and observe 5 V supply decoupling guidelines. The MultiVolt I/O feature requires per-bank VCCIO rails that must be tied to either 3.3 V or 5.0 V - mixing within a bank is not supported. This page synthesizes distributor pricing, drop-in FLEX 8000 family alternatives, and design guidance beyond the manufacturer datasheet, including parametric comparison and selection criteria for engineers evaluating legacy Altera SRAM FPGAs.

EPF8282ALC84-4

EPF8282ALC84-4 - 2.5K FLEX 8000 FPGA, 84-PLCC, 5V | Altera

The Altera EPF8282ALC84-4 is a member of the FLEX 8000 family of SRAM-based CMOS Field Programmable Gate Arrays (FPGAs) housed in an 84-pin PLCC (Plastic Leaded Chip Carrier, J-Lead) package. The device integrates 208 logic elements arranged in 26 Logic Array Blocks (LABs) and provides 68 user I/O pins for high-density, register-rich programmable logic designs. It is supplied from a nominal 5V rail (4.75V-5.25V) and operates over the commercial 0C to +70C temperature range. The -4 speed grade reflects the slowest of the FLEX 8000 family grades, providing the longest propagation delay but at the lowest cost. An FPGA (Field-Programmable Gate Array) is a programmable logic device belonging to the broader PLD (Programmable Logic Device) family, which itself falls under digital ICs and semiconductors. FPGAs sit hierarchically above simple PLDs and below ASICs, offering higher logic density than CPLDs while preserving field programmability. The FLEX 8000 series combines the high register count and fine-grained interconnect of an FPGA with features normally associated with mask-programmed gate arrays, including in-circuit reconfigurability (ICR) via SRAM configuration cells. Key features include 2,500 usable gates, 208 logic elements, 26 LABs, and 68 user I/Os. The FLEX 8000 architecture uses CMOS SRAM configuration elements that are loaded at system power-up from an industry-standard parallel EPROM, an Altera serial configuration device (EPC1, EPC1213, EPC1064, or EPC1441), or a system controller. MultiVolt I/O allows the device to interface with mixed-voltage systems supporting 3.3V or 5.0V I/O pin operation across the family. Typical applications include glue logic replacement, bus interface bridging, state-machine and controller implementation, peripheral emulation in legacy industrial systems, and prototyping of larger ASIC designs. The 5V tolerance and PLCC footprint make it well-suited to long-lifecycle industrial and telecom designs where through-hole or socketed assembly is preferred over fine-pitch QFP. Designers should note that the SRAM-based configuration is volatile: the device must be reconfigured at every power-up. PCB layouts must respect the PLCC-84 socket's mechanical constraints and provide a robust configuration source. As a -4 speed-grade part, propagation delay is the longest in the family - consult the FLEX 8000 datasheet for timing margins in time-critical paths.
