EP1810LC-20

EP1810LC-20 - 900-Gate Classic EPLD, 48 Macrocells, 20ns | Intel

The Intel (formerly Altera) EP1810LC-20 is a member of the Classic EPLD (Erasable Programmable Logic Device) family that delivers 900 usable gates, 48 macrocells, and a 20 ns pin-to-pin propagation delay in a 68-pin PLCC package. It operates from a single 5 V supply and is offered in a windowed (L) UV-erasable or OTP variant, making it suitable for both prototyping and production. The 'LC' suffix designates the PLCC package family while '20' denotes the 20 ns commercial speed grade. An EPLD is an Erasable Programmable Logic Device - a member of the programmable logic hierarchy that sits between discrete PAL/GAL devices and modern CPLDs. Within the broader taxonomy it is a complex PLD that combines multiple PAL-like AND/OR arrays with a configurable macrocell fabric. Classic EPLDs were the predecessors to today's CPLDs, offering non-volatile, instant-on configuration, deterministic timing, and high drive capability - characteristics still valued in glue logic, bus interface, and state-machine replacement applications. Key features of the EP1810LC-20 include 48 macrocells interconnected by global and local buses, 12 dedicated inputs, and a maximum toggle frequency of 50 MHz. The device provides bi-directional I/O pins with user-configurable output enable polarity, programmable macrocell flip-flops with D, T, JK, and SR modes, and 100% generically testable logic. Power dissipation is low for a 5 V CMOS EPLD, and the part supports ISP (In-System Programmability) on selected variants via the Altera programming algorithm. The architecture integrates a programmable AND array feeding a fixed OR array, the classic sum-of-products realization that made the Classic family attractive for state-machine and decoder logic. Each macrocell contains a programmable flip-flop, output polarity selection, and feedback path so that registered or combinatorial outputs can be routed back into the AND plane - enabling dense sequential designs in a single device. Typical applications for the EP1810LC-20 include address decoding and glue logic in legacy 5 V systems, peripheral interface controllers for ISA/VME/Motorola bus architectures, state machines in industrial controllers, and pin-compatible replacements for discrete 74LS/74S TTL logic. The device is well suited to long-life-cycle industrial, military, and avionics programs where the part's 25+ year production track record is more important than raw density. When designing with the EP1810LC-20, ensure all inputs are within TTL thresholds for the 5 V interface and place decoupling capacitors (0.1 uF per VCC pin group) close to the package. The Classic family's deterministic timing model (tPD 20 ns, tCO 15 ns, tSU 15 ns) allows static timing analysis without place-and-route iterations, which is a significant advantage over modern SRAM-based FPGAs for safety-critical designs.

EP1810LC-20T

EP1810LC-20T - Classic CPLD 900 Gates 48 Macrocells 5V PLCC-68 | Intel

The Intel (Altera) EP1810LC-20T is a member of the Altera Classic EPLD family, providing 900 usable gates, 48 macrocells, and a maximum toggle frequency of 50 MHz in a 68-pin PLCC (J-lead) package. It operates from a single 5 V supply and is specified over the commercial temperature range, with the "-20" speed grade indicating a 20 ns pin-to-pin logic delay and the "T" suffix denoting a tape-and-reel shipping format. A CPLD (Complex Programmable Logic Device) is a non-volatile programmable logic device that sits in the programmable-logic hierarchy between simple PLDs (PAL/GAL) and high-density FPGAs. The Classic EPLD architecture combines AND/OR array logic with a fixed, deterministic interconnect fabric and an EEPROM-based configuration memory, giving designers a glue-logic alternative to discrete TTL or CMOS gates for decoder, bus-interface, state-machine, and peripheral-control functions. Key features of the EP1810LC-20T include 48 macrocells organized across four Logic Array Blocks (LABs) of 12 macrocells each, a sum-of-products (product-term) architecture with both combinatorial and registered (D-type flip-flop) outputs, and a JTAG-compliant IEEE 1149.1 boundary-scan interface for in-system programming and test. The 5 V core simplifies interface to legacy 5 V TTL logic without level shifters, and the PLCC-68 package offers socket-friendly field upgrades for prototype and production environments. Architecturally, the device uses Altera's Classic MAX-style interconnect: each macrocell distributes product terms across the LAB and feeds an I/O pin through a tri-state output buffer. Configuration is stored in on-chip EEPROM, eliminating the need for an external boot PROM and providing instant-on operation at power-up. Programming is performed via the JTAG port or the older Altera Master/Slave serial interface. Typical applications include 5 V bus-interface and address decoding in industrial control backplanes, glue-logic replacement for legacy 74-series designs, I/O expansion and timing-control blocks, state-machine and protocol-bridging logic, and small-scale register/buffer functions in test equipment. The non-volatile EEPROM configuration also makes it well-suited to safety-critical or boot-loader designs that must come up in a known state. When designing with the EP1810LC-20T, ensure that all unused I/O pins are configured as outputs driving a defined logic level or as inputs with internal pull-ups enabled, to avoid supply-current transients. Decouple VCC with 0.1 microfarad ceramic capacitors placed within 5 mm of each VCC/GND pair, and observe the device's 5 V absolute-maximum rating when hot-plugging into mixed-voltage buses. This page synthesizes distributor pricing, drop-in alternatives from the Altera Classic family, and practical design notes that go beyond the manufacturer datasheet, including pin-compatibility flags and engineering guidance for migrating to modern MAX-series replacements.

The EP1810LC-25 features 12 dedicated inputs and 48 bidirectional I/O lines, organized around the Programmable Logic Array (PLA) structure typical of the Classic family. It supports four external clock signals and provides Turbo-only operation, which eliminates the slow- speed power-consumption mode and reduces active current without sacrificing performance. Logic is implemented in 48 macrocells, each with programmable register feedback. Typical applications include 5 V glue-logic replacement, address decoding for microprocessor systems, bus-interface arbitration, peripheral controllers, and state-machine consolidation in industrial and telecom systems. The wide package and 5 V tolerance make the EP1810LC-25 well suited to legacy system designs that require TTL-compatible logic levels. The device is also commonly used for educational and prototyping platforms where Erasable Programmable Logic Device architecture is being demonstrated. When designing with the EP1810LC-25, ensure the 5 V supply is well decoupled (0.1 uF ceramic + bulk) and respect the maximum I/O sink/source ratings for TTL loads. Programming is performed using Altera's Classic-device programmer and the MAX+PLUS II legacy toolchain; modern replacements require migration to MAX II or MAX V CPLDs.

EPLDs sit in the programmable logic hierarchy between simple SPLDs (PAL/GAL) and larger FPGAs, offering deterministic propagation delay, high input-to-output pin ratios, and excellent bus-holding capability — making them the industry standard for address decoding, bus arbitration, and peripheral interfacing in 5 V industrial systems. The EP1810LC-25T's 48-macrocell density translates into roughly 900 usable gates, with TTL-compatible 5 V I/O, four global clock networks, and a nominal supply voltage of 5 V. The LC-25T speed grade corresponds to a 25 ns pin-to-pin propagation delay, the commercial operating range is 0 °C to 70 °C, and the package is the 28-pin PLCC (Plastic Leaded Chip Carrier) surface-mount form factor. Typical applications include 5 V TTL/CMOS address decoding in legacy 8086/8051/Motorola 68k systems, peripheral bus interfacing (ISA, PC/104, STD bus), state-machine-based control logic, and bus arbitration glue logic. Designers value the device for its deterministic timing, single-chip non-volatile operation, and the ability to replace multiple discrete 74LS/74F-series TTL packages. When designing with this EPLD, confirm that the 5 V VCC tolerance matches all attached logic families, allow adequate decoupling (100 nF plus 10 µF bulk) near the supply pins, and use the Altera MAX+PLUS II or Quartus Classic development flow for programming the OTP/EPROM cells. Note that the EP1810 series is now legacy and may require sourcing from authorized distributors; XAIPART provides traceable stock for production continuity.

EP1810LC-30

EP1810LC-30 - 48-Macrocell Classic EPLD, 30ns | Altera

The Intel/Altera EP1810LC-30 is a 48-macrocell Classic EPLD (Erasable Programmable Logic Device) from Altera's Classic device family, fabricated on advanced CMOS technology and offered in a 68-pin ceramic J-Lead chip carrier (JLCC-68) package. The "LC" suffix denotes the low-power CMOS variant, the "-30" speed grade specifies 30 ns pin-to-pin logic delay (tPD), and the device integrates 48 macrocells with up to 48 flip-flops for combinatorial and registered logic implementation in high-speed, low-power glue-logic applications. The EP1810LC-30 typically operates from a 5 V supply and is specified over the commercial or industrial temperature range, making it suitable for legacy digital control designs. Classic EPLDs occupy a specific niche in the programmable logic taxonomy: they sit between discrete TTL/CMOS glue logic (PAL/GAL) and modern SRAM-based FPGAs. An EPLD is a one-time- or UV-erasable PLD that uses sum-of-products macrocell architecture to implement combinational and registered logic. Compared to simple 22V10-style PALs, a Classic EPLD offers higher macrocell density, predictable timing, and lower power consumption than equivalent discrete SSI/MSI implementations. Compared to FPGAs, EPLDs provide instant-on behavior (no configuration PROM required), deterministic fixed timing, and very low standby current, which is why they remained popular for control-plane glue logic, bus interfacing, and address decoding well into the 2000s. The EP1810LC-30 supports typical tPD (propagation delay) of 30 ns at 5 V operation, four dedicated input pins, a global clock network, and asynchronous clear/preset on each macrocell. Programmable I/O architecture allows each pin to be configured as input, output, or bidirectional with output enable control. The device is in-system programmable through a JTAG-compatible interface and provides security-bit support to protect designs from readback. Typical applications include address decoding for microprocessor/microcontroller systems, bus interfacing and arbitration logic, state-machine and sequencer replacement for discrete 74LS/74HC logic, peripheral glue logic in legacy industrial controllers, and replacement of multiple discrete PLD/PAL devices with a single integrated part. The 30 ns speed grade is well-matched to 8-bit and 16-bit bus interfaces (e.g., 8086, 68000) where address decode must complete within one clock cycle. When designing with the EP1810LC-30, account for the ceramic package thermal mass (suitable for harsh environments) and the 30 ns propagation delay when computing system timing margins. For new designs, modern CPLDs from Intel (MAX series) or Lattice (ispMACH) provide higher density and lower power in smaller packages, but the EP1810LC-30 remains in demand as a drop-in replacement for legacy boards.

EP1810LC-35

EP1810LC-35 - 48-Macrocell Classic EPLD, 35ns, PLCC-68 | Rochester/Altera

The Rochester Electronics (originally Altera) EP1810LC-35 is a Classic-series Erasable Programmable Logic Device (EPLD) from the EP1810 family, offering 48 macrocells and approximately 900 usable gates of user-configurable logic in a 68-pin Plastic J-Lead Chip Carrier (PLCC) package. Per the original Altera datasheet, the EP1810LC-35 variant is specified with a 35ns propagation delay (the '-35' speed grade), operates from a 5V supply, and is fabricated in CMOS UV-erasable technology. It implements up to 2100 equivalent gates of conventional SSI/MSI/LSI logic while delivering TTL-equivalent speed at low power consumption. An EPLD (Erasable Programmable Logic Device) is a non-volatile, UV-erasable member of the programmable logic family that sits in the broader hierarchy of PLDs > CPLDs > programmable logic > digital semiconductors. Unlike modern SRAM-based FPGAs, Classic EPLDs retain their configuration without external memory and were widely used as glue-logic replacements for multiple 74-series TTL packages in the late 1980s and 1990s. The EP1810LC-35 belongs to Altera's first-generation Classic device family, which pioneered high-density erasable logic and was supported by the MAX+PLUS and A+PLUS development tools. Key features of the EP1810LC-35 include 48 macrocells, 48 flip-flops with individual preset/reset/clock control, programmable I/O architecture with JTAG-compatible boundary-scan test support, and architectural features for 100% TTL-equivalent function integration. Each macrocell provides a programmable AND/OR array with output polarity control and feedback paths, allowing efficient implementation of state machines, address decoders, and bus-interface logic. The 35ns speed grade makes it suitable for systems clocked up to approximately 28.6 MHz. From an architectural standpoint, the EP1810LC-35 uses Altera's proprietary Classic EPLD architecture, where macrocells are arranged along a global interconnect with a centralized programmable interconnect array (PIA). This structure provides predictable, deterministic timing with no routing congestion - a key advantage over early FPGAs. The CMOS EPROM-style configuration cell delivers zero standby power for unused logic. Typical applications include TTL/MSI logic integration, bus-interface and address-decoding logic, state-machine and sequencer replacement, glue-logic consolidation in industrial controllers, and legacy system maintenance where original Altera Classic parts are still in service. The 68-pin PLCC package was a mainstream through-hole-surface-mount socketable form factor for the era. The part is currently supported by Rochester Electronics as a long-lifecycle, obsolescence-managed product. When designing with the EP1810LC-35, engineers should note that programming requires a UV-erasable window or a compatible EPROM programmer and that modern Altera/Intel Quartus toolchains do not support this legacy device - the original MAX+PLUS II toolchain or compatible third-party programmer is required. Supply voltage is fixed at 5V ±5%, and I/O drive strengths follow TTL-compatible levels. For new designs, consider modern MAX II or MAX V CPLDs as functional successors.

The Intel (formerly Altera) EP1810LC-35T is a member of the EP1810 Classic EPLD family, a high-speed, low-power CMOS Erasable Programmable Logic Device (EPLD) packaged in a 68-pin Plastic Leaded Chip Carrier (PLCC) with tape-and-reel packaging. The device integrates 900 usable gates organized into 48 macro cells, supports a pin-to-pin propagation delay of 35 ns (tpd), and operates from a 5 V supply with a maximum toggle frequency of 28.6 MHz. An EPLD (Erasable Programmable Logic Device) is a type of non-volatile programmable logic that combines the flexibility of a PLD with on-chip macrocell architecture, sitting in the hierarchy between simple PLDs (PAL/GAL) and more complex CPLDs/FPGAs. The EP1810 family in particular was designed as a low-power Schottky TTL replacement, providing integrated multi-PAL/GAL functionality on a single CMOS die. The 'E' in EPLD refers to the erasable (UV-erasable ceramic or one-time-programmable plastic) technology used to program the AND/OR array. Key features of the EP1810LC-35T include 48 individually-configurable macro cells that can be programmed as D, T, JK, or SR flip-flops (or for combinatorial operation), 100% TTL emulation capability, and on-board logic test circuitry for production AC verification. The device supports multiple independent clock options for register clocking and offers JTAG-free boundary-scan test via dedicated pins. The LC suffix indicates commercial 0 C to +70 C operating temperature and the 35 ns speed grade. Architecturally, the EP1810LC-35T uses a programmable AND/OR sum-of-products array feeding into 48 macrocells, each containing a flip-flop and output enable control. The Classic EPLD architecture predates modern look-up-table (LUT) based FPGAs and is optimized for glue-logic, bus decoding, state-machine, and address- decoding applications where deterministic 35 ns timing and 5 V tolerance are required. Typical applications include TTL-logic replacement (integrating multiple 74LS gates), address decoding for microprocessor systems, glue logic between microprocessors and peripherals, state machines in industrial control, and bus-interface arbitration. The 5 V tolerant I/O makes it ideal for legacy 5 V system designs, while the 35 ns speed grade offers adequate performance for many bus-control applications. When designing with the EP1810LC-35T, note that it requires the legacy Altera MAX+PLUS II development environment for programming (JEDEC file generation). Modern Intel Quartus does not support Classic EPLDs. Ensure the PCB footprint matches the standard 68-pin PLCC J-lead pattern with 1.27 mm pitch.

The device is in-system UV-erasable (windowed package variant) and supports a 5 V ±5% supply with TTL-compatible I/O. According to the datasheet description on Alldatasheet, the EP1810LC-45 is rated for commercial operating conditions with a 45 ns pin-to-pin delay, making it suitable for designs previously implemented with discrete 74LS/74F glue logic. Architecturally, the EP1810LC-45 uses Altera's Classic MAX-like macro cell with sum-of-products logic feeding a configurable flip-flop. The 5 V CMOS EPROM-based process gives the part excellent radiation tolerance and long-term data retention (>10 years), which explains its continued use in aerospace, defense, and long-lifecycle industrial systems where modern FPGAs would be overkill or unavailable. Typical applications include legacy bus-interface adapters, address decoders, peripheral controllers in industrial PLCs, vintage telecom backplane glue logic, and MIL-STD-883 aerospace subsystems. The 68-pin PLCC footprint with J-leads also suits socketed field-replaceable modules where UV-erase and reprogram cycles are required during development. When designing with the EP1810LC-45, plan the 5 V supply with 100 nF + 10 µF decoupling placed within 5 mm of each VCC/ground pair. Because this is an obsolete part now supplied only by Rochester Electronics, design engineers should treat it as last-time-buy inventory and consider migrating to MAX 3000A, MAX II, or modern Intel MAX 10 CPLDs for new designs.

The Altera EP1810LI-35 is a high-density CMOS Erasable Programmable Logic Device (EPLD) from Altera's Classic EPLD family, offering 48 macrocells with a 35ns propagation delay in a 68-pin PLCC (J-Lead) package. It provides high-speed, low-power logic integration for glue-logic, decoder, encoder, state-machine, and bus-interface applications that traditionally required multiple TTL or CMOS SSI/MSI parts. A Classic EPLD is a one-time-programmable (OTP) or UV-erasable PLD that combines the architecture flexibility of a gate array with the non-volatility and instant-on characteristics of a programmable read-only memory. In the broader system hierarchy, EPLDs sit between simple SPLDs/CPLDs on the low-density side and full FPGAs on the high-density side: they offer deterministic timing, wide-input AND/OR arrays, and a fixed number of macrocells wired together by a programmable interconnect — well suited to 5V legacy systems and industrial control boards. Key features include 48 macrocells, 16 dedicated input pins, an industry-standard JTAG (IEEE 1149.1) boundary-scan interface for in-system programming and test, and TTL-compatible I/O. The EP1810LI-35 uses Altera's MAX-style architecture with multiple Logic Array Blocks (LABs) connected through a programmable interconnect array (PIA). Standby current is typically in the low milliamp range, and the 'L' suffix denotes a low-power CMOS variant suitable for battery-backed industrial systems. Typical applications include address decoding for 16/32-bit microprocessor and DSP systems, peripheral glue logic replacement, bus arbitration, control logic in data-acquisition front ends, and legacy industrial controller upgrades. Because the device is fabricated on advanced CMOS technology with EPROM-based configuration cells, the EP1810LI-35 retains its programmed logic across power cycles with zero configuration time, an important advantage over SRAM-based FPGAs in deterministic-startup applications. When designing with this device, allow adequate decoupling (0.1 uF ceramic on every VCC/ground pair) and verify that the 35ns tPD still meets the target system's setup-and-hold budget — the '35' speed grade is the slowest member of the EP1810L family, so engineers seeking more timing margin should consider EP1810LI-25 or EP1810LC-20 (commercial/ceramic-package variants in the Site MPN list).

EPLDs sit within the programmable logic hierarchy below CPLDs and FPGAs: PLA -> PAL -> EPLD -> CPLD -> FPGA. Unlike SRAM-based FPGAs, EPLDs retain their configuration without external memory, making them well suited to deterministic, instant-on glue-logic replacement of multiple SSI/MSI gates in cost-sensitive designs. Key features include 48 macrocells, 22 ns tPD (propagation delay), 12 dedicated inputs, 48 I/O pins, J-bend PLCC-68 footprint with 1.27 mm pitch, and CMOS low-power operation. The device typically consumes around 20 mA when operating at 1 MHz, and per the Jotrin product profile it can implement four 12-bit counters at up to 50 MHz. The -20 speed grade suffix indicates a 20 ns (or 22 ns per other sources) worst-case pin-to-pin delay, the fastest grade offered in the EP1830 family. Architecturally, the EP1830 is built around a sum-of-products AND/OR array with programmable macrocell flip-flops, all wired through a global interconnect. The CMOS EPROM process provides non-volatility and zero standby current for the configuration, while a TTL-compatible I/O structure simplifies interface with legacy 5 V logic families such as 74LS, 74HC, and 74F. Commercial temperature grading (0C to 70C) targets office and light-industrial environments. Typical applications include bus-interface decoding for 8086/80386 microprocessors, address decoding for memory and peripheral mapping, glue-logic consolidation replacing 74-series TTL gates, state-machine implementation, and counter/timer designs. The instant-on, deterministic timing of the EP1830 makes it especially attractive in safety-conscious or real-time control systems where SRAM-FPGA configuration delays are unacceptable. When designing with the EP1830-20CFN, ensure the design tools used (e.g., MAX+PLUS II or compatible Altera-compatible third-party suites) match the JEDEC fuse-map output and that the I/O drive does not exceed the 5.25 V absolute-maximum supply. Unused I/O pins should be left floating or tied per the application note; the dedicated-input pins must remain at valid logic levels to avoid spurious supply current. As an older CMOS EPLD, the device should be handled with standard ESD precautions. This page synthesizes distributor pricing, parametric alternatives, and practical design considerations not found in the standalone datasheet, giving engineers a single source for sourcing, replacement, and design validation of the EP1830-20CFN.

Typical applications include telecommunications backplane aggregation, video broadcast equipment using SDI interfaces, industrial imaging and machine vision systems, wireless baseband processing, and high-speed serial protocol bridging. The combination of transceiver channels and DSP blocks makes this device particularly suitable for designs that need both multi-gigabit serial I/O and signal processing throughput. When designing with this part, verify the FC-FBGA ball pattern, signal-integrity stackup, and thermal solution against the device handbook. The C6 speed grade specifies worst-case timing at typical silicon process conditions - confirm timing closure in Quartus II at the target speed grade before committing to PCB layout. Legacy Arria GX designs should also evaluate migration to Arria II GX or Cyclone IV GX for new production runs. This page synthesizes distributor pricing, parametric specifications, and same-package drop-in alternatives that complement the official Altera handbook with practical sourcing context.

EP1AGX20CF780C6N

EP1AGX20CF780C6N - Arria GX FPGA, 21K LE, FBGA-780 | Intel

The Intel (formerly Altera) EP1AGX20CF780C6N is a member of the Arria GX family of field-programmable gate arrays (FPGAs) housed in a 780-ball flip-chip BGA package with 29 x 29 mm body and 1.0 mm ball pitch. The device integrates approximately 21,580 logic elements (equivalent to 21,580 CLBs in marketing material) organized across 1,079 logic array blocks (LABs), supported by 1,229,184 bits of embedded memory and 341 user I/O pins. Built on a 1.2 V core, 90 nm process technology, the EP1AGX20CF780C6N is rated for industrial-grade commercial temperatures (C6 speed grade) and provides up to four integrated multi-gigabit transceivers capable of data rates up to 3.125 Gbps for serial connectivity. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs), programmable routing, and dedicated hardware blocks such as memory, DSP, PLLs, and (on transceiver families) multi-gigabit transceivers. FPGAs belong to the broader category of programmable logic devices (PLDs) within the integrated-circuit hierarchy: PLD -> CPLD/FPGA -> FPGA with transceivers -> SoC FPGA. Unlike a fixed-function ASIC, an FPGA's logic and routing can be redefined after manufacture, making FPGAs ideal for prototyping, low-volume production, and applications requiring post-deployment firmware upgrades. The Arria GX family specifically targets cost-sensitive designs that need integrated transceivers without the cost premium of the high-end Stratix family. Key features of the EP1AGX20CF780C6N include built-in CDR/PMA for serial protocols such as PCI Express, Gigabit Ethernet, Serial RapidIO, and XAUI, up to 6.5 Mbits of dedicated on-chip memory configurable as true dual-port or simple dual-port RAM, and embedded DSP blocks that support 18x18 multipliers at up to 250 MHz. The device supports configuration via passive serial (PS), fast passive parallel (FPP), active serial (AS), and JTAG modes using Altera/Intel Quartus II design software. The EP1AGX20CF780C6N's transceiver capability, dense logic, and large memory capacity make it particularly well-suited for high-speed serial interface bridging in communications equipment, low-cost PCI Express endpoint cards, broadcast video processing engines, and DSP co-processing. The flip-chip FBGA-780 package provides the necessary signal and power integrity for multi-gigabit SERDES operation. The C6 speed grade balances timing margin and cost for most commercial applications. When designing with the EP1AGX20CF780C6N, allocate at least eight PCB layers with continuous VCC and GND planes, route all transceiver channels with controlled 100-ohm differential impedance, and provide DC-blocking capacitors on each serial TX/RX pair. Decoupling must include 100 nF X7R capacitors within 100 mil of every VCC pin to meet multi-gigabit transceiver jitter budgets.

EP1AGX20CF780I6

EP1AGX20CF780I6 - Arria GX FPGA, 20K LE, 341 I/O | Intel

The Intel (formerly Altera) EP1AGX20CF780I6 is a member of the Arria GX family of field-programmable gate arrays (FPGAs) manufactured on a 90 nm CMOS process, integrating 21,580 logic elements in a 780-pin FC-FBGA (Fine-pitch Chip-scale Fine-pitch Ball Grid Array) package with 341 user I/O pins. The device operates from a 1.2 V core supply and embeds up to 1,229,184 bits of embedded memory distributed across 1,079 logic array blocks (LABs). The CF780 suffix denotes the 780-ball flip-chip BGA package and the industrial temperature grade (-40 C to +100 C junction). The 'I' speed grade and '6' designator reflect Altera's mid-band speed bin targeting 1.2 Gbps transceiver operation. A field-programmable gate array (FPGA) is a programmable semiconductor device that allows designers to configure its digital logic blocks, interconnect, and I/O cells after manufacture. FPGAs occupy the high-flexibility tier between discrete logic ICs and fixed-function ASICs in the digital design hierarchy: chip -> programmable logic -> FPGA -> CPLD. Arria GX specifically targets mid-range applications requiring embedded transceivers and moderate logic density, fitting between the lower-cost Cyclone family and the higher-end Stratix family. The EP1AGX20CF780I6 features up to 4 embedded transceivers capable of data rates from 600 Mbps to 3.125 Gbps, supporting serial protocols such as PCI Express (x1/x4), Gigabit Ethernet, Serial RapidIO, and SerialLite II. The device also integrates dedicated DSP blocks for high-throughput signal processing, hardware multipliers, and phase-locked loops (PLLs) for clock management. Configuration is supported through passive serial (PS), fast passive parallel (FPP), and JTAG modes, with built-in decompression and decryption for bitstream security. Architecturally, the EP1AGX20CF780I6 combines logic element granularity with high-speed serial interfaces, eliminating the need for external PHY chips in many protocol applications. The 90 nm process node delivers a balance between static power consumption and switching performance, and the industrial temperature range supports deployment in harsh-environment embedded systems. The flip-chip BGA package enables high I/O density with controlled impedance signal paths suitable for multi-gigabit serial links. Typical applications include telecommunications line cards, industrial video processing, medical imaging systems, military and aerospace signal processing, and PCI Express endpoint cards. The combination of integrated transceivers and 20K logic elements makes this device suitable for protocol bridging, custom high-speed data acquisition, and DSP-accelerated image and signal pipelines. When designing with this device, plan power distribution carefully - the 1.2 V core rail requires bulk decoupling close to the package, and the transceiver PLLs need isolated analog supply domains with ferrite-bead filtering. PCB layout must preserve 90 ohm differential impedance on all serial channels and meet length-matching constraints for source-synchronous buses. Configuration storage via EPCS or EPCQ serial flash should be sized for the compressed bitstream with overhead. This page synthesizes distributor availability, parametric positioning within the Arria GX family, and practical design guidance that is not consolidated in the manufacturer datasheet alone.
