EP1830-20CFN - 48-Macrocell CMOS EPLD, 22ns, PLCC-68 | TI
The Texas Instruments EP1830-20CFN is a 48-macrocell erasable programmable logic device (EPLD) fabricated in CMOS technology, with a 22 ns propagation delay and 48 I/O lines housed in a 68-pin PLCC (J-lead, QCCJ) package. It operates from a maximum supply voltage of 5.25 V, with 12 dedicated inputs and a 1.27 mm terminal pitch, making it suitable for glue-logic and bus-interface integration in legacy and industrial systems. An EPLD (Erasable Programmable Logic Device) is a non-volatile programmable logic device that uses CMOS EPROM cells to store the AND/OR array configuration. 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.

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.

EP1AGX35CF484C4N - Arria GX FPGA | Altera | Industrial
The Altera EP1AGX35CF484C4N is an Arria GX Field Programmable Gate Array, or FPGA, in a 484-BBGA package. The supplied verified data identifies it as a programmable logic IC; exact core voltage, operating temperature, logic-element count, transceiver count, and speed-grade parameters are not exposed in the source snippets and are therefore not inferred here. The part designation includes a C4 speed-grade code and an N suffix, but the available evidence does not provide a verified electrical or package-dimension table for this exact ordering code. An FPGA is a semiconductor device containing configurable logic, programmable interconnects, and typically embedded functional blocks. It sits in the hierarchy of programmable logic devices, above fixed-function integrated circuits and below application-specific system functions. Unlike an ASIC, an FPGA can be configured after manufacturing, allowing hardware logic to be revised without changing the printed circuit board. Arria GX is a programmable-logic family intended for applications requiring configurable digital processing and high-speed interfaces. The principal verified identifying feature is the Arria GX FPGA family, which is associated in the supplied family search result with 3.125 gigabits per second serial transceivers. For EP1AGX35CF484C4N, however, the number of transceivers and all other headline performance values must be confirmed from the manufacturer datasheet before design release. The 484-BBGA package is also a verified package identifier, making it a key mechanical constraint for replacement decisions. The exact ball map is not included in the supplied data and should be obtained from the official datasheet. Programmability is the device’s central engineering value: logic, interfaces, and data-processing functions can be adapted to changing system requirements. Designers use FPGA configuration, clocking, I/O, and power constraints to implement parallel digital functions, protocol handling, or test and measurement logic. The supplied family material describes 3.125 Gbps serial transceivers, but this page does not claim that value as a guaranteed specification for the target ordering code because the target-specific source record is incomplete. Potential applications include communications equipment, industrial control, test and measurement, and embedded systems that need configurable high-speed digital logic. These uses require careful validation of I/O standards, transceiver configuration, power sequencing, thermal behavior, package-ball compatibility, and configuration-memory requirements. Engineers should treat the C4 ordering code and package designation as exact identifiers, while confirming target-specific limits in the official documentation. The primary design caution is replacement safety: an FPGA alternative is not a drop-in substitute merely because it uses a 484-BBGA package. Pin-to-pin compatibility also requires identical ball assignments, power rails, I/O capabilities, transceiver behavior, configuration, density, and timing characteristics. No verified five-part drop-in cross-reference was supplied, so unverified alternatives are intentionally not presented. This information-gain approach preserves PCB-design integrity and distinguishes package similarity from functional equivalence. This page combines the exact target MPN, verified Arria GX family context, package identifier, sourcing URLs, and explicit data gaps. It is designed to support procurement research while avoiding unsupported specifications, guessed pinouts, fabricated document numbers, or unsupported pricing claims.

Architecturally, the EP1AGX35DF780C5N uses a 90 nm SRAM-based logic fabric with embedded memory blocks (M512, M4K, M-RAM) and dedicated DSP blocks (each block containing four 18x18 multipliers plus adder/accumulator logic). The transceiver blocks support both PCI Express (PIPE) and Gigabit Ethernet (GIGE) hard IP, eliminating soft-logic serialization and substantially reducing FPGA fabric utilization for serial interfaces. Typical applications include PCI Express endpoint cards, multi-port Gigabit Ethernet switches, SDI/HD-SDI video processing, Serial RapidIO bridges for wireless baseband DSP, and protocol aggregation in telecom line cards. The 780-BGA package with exposed thermal pad supports industrial-temperature operation with adequate PCB thermal design. When designing with this device, engineers should evaluate migration to the Cyclone IV GX or Cyclone V GX family for new designs, as Arria GX is in mature lifecycle status with limited distributor inventory. For full hardware validation, always consult the official Arria GX Device Handbook for transceiver characterization and IBIS models for signal-integrity simulations.

EP1AGX35DF780C6 - 33,520-Cell Arria GX FPGA | Intel
Intel EP1AGX35DF780C6 is a field-programmable gate array from the Arria GX family, built on 90 nm process technology and supplied in a 780-pin FC-FBGA package. Verified specifications identify 33,520 logic cells, a 1.2 V supply, 341 I/O terminals, and a C6 speed grade. It is a programmable semiconductor that combines configurable logic, embedded memory, digital signal processing resources, and high-speed transceiver capability in one device. The package designation indicates a fine-pitch ball-grid array, making it appropriate for high-density printed-circuit designs rather than low-cost through-hole assembly. An FPGA, or field-programmable gate array, is a programmable semiconductor that implements digital logic through a configurable matrix of logic elements, routing resources, memory blocks, and specialized I/O circuits. Unlike an application-specific integrated circuit, the FPGA configuration can be changed after manufacturing. In the system hierarchy, an FPGA sits between general-purpose processors and fixed-function ASICs: it can provide hardware parallelism, deterministic interfaces, protocol bridging, signal processing, and logic consolidation. The Arria GX family is designed for data-path and communications-oriented designs where programmable high-speed interfaces are important. The verified headline characteristics are 33,520 cells, 1.2 V operation, 341 I/O pins, 90 nm technology, and a 780-pin FC-FBGA package. The 1.2 V supply supports low-voltage digital implementation, while 341 I/O terminals provide broad connectivity for parallel interfaces, memory controllers, custom logic, and data-conversion links. A 780-terminal BGA also provides high I/O density, but it requires controlled PCB escape routing, via structures, thermal analysis, assembly capability, and careful signal-integrity review. The C6 suffix denotes the commercial C6 speed grade in the ordering information. Designers should treat the FPGA architecture as programmable hardware: logic functions are implemented through a device-specific configuration bitstream generated with supported Intel or Altera design tools. The configuration must match the exact device, package, speed grade, and design revision. Engineering sign-off should therefore include power estimation, pin assignment, timing closure, I/O standards, configuration scheme, and post-layout signal-integrity verification rather than relying on functional simulation alone. Typical applications include communications equipment, data acquisition systems, industrial imaging, video and display processing, protocol conversion, test and measurement hardware, and embedded control. EP1AGX35DF780C6 is most suitable when a design needs substantial programmable logic and high I/O count in a compact BGA footprint. Its Arria GX positioning also makes it relevant to designs that benefit from high-speed serial connectivity, although exact transceiver counts, data rates, memory resources, and supported I/O standards are not included in the verified snippets and must be confirmed from the manufacturer datasheet before design release. A primary design consideration is BGA implementation. Confirm the ball map, land pattern, stack-up, via-in-pad or dog-bone escape strategy, decoupling network, clock distribution, and thermal solution against the official manufacturer package documentation. Use the exact manufacturer datasheet for the device because distributor summaries can omit architecture and timing details. This page combines verified package, cell-count, process, supply, I/O, and speed-grade facts with a practical implementation checklist for procurement and PCB planning.
EP1AGX35DF780C6N - Arria GX FPGA, 33.5K LEs, 3.125 Gbps | Altera
The Intel (formerly Altera) EP1AGX35DF780C6N is a member of the Arria GX family of field-programmable gate arrays (FPGAs) that combines 3.125 gigabits per second (Gbps) serial transceivers with reliable packaging technology. The device integrates 33,520 logic elements (equivalent to 16,725 adaptive logic modules / 33,520 four-input lookup tables) and 1,348,416 bits of embedded memory in a 780-ball flip-chip BGA (FC-FBGA) package measuring 29 x 29 mm with 1.0 mm ball pitch. It is fabricated on a 90 nm process and operates from a 1.2 V core supply with separate transceiver and auxiliary rails. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs/LABs), programmable routing, and dedicated hard IP such as transceivers, memory controllers, and PLLs. FPGAs sit between general-purpose microcontrollers and fixed-function ASICs: like an ASIC they achieve high parallelism and deterministic timing, but unlike an ASIC the logic is defined at runtime through a hardware description language (HDL) and configuration bitstream. Within the broader taxonomy FPGAs belong to programmable logic devices (PLDs) and represent the highest-density member of that family. Key features of the EP1AGX35DF780C6N include up to 8 full-duplex CDR-based transceivers supporting data rates from 600 Mbps to 3.125 Gbps across standards such as PCI Express Gen1, Gigabit Ethernet, Serial RapidIO, and XAUI. The device provides 4 PLLs (2 fast PLLs for transceivers plus 2 enhanced PLLs for general use), up to 341 user I/O pins, and dedicated 8b/10b encoding/decoding hardware on every transceiver channel. A C6 speed grade indicates the standard performance corner, while the extended temperature range ('N' suffix absent here) targets commercial 0C to 85C operation. On the architecture side, the Arria GX device fabric embeds TriMatrix memory blocks (MLAB, M512, M4K, M-RAM) totaling roughly 1.35 Mbits, supporting true dual-port operation and mixed-width data paths. Configuration is supported through passive serial (PS), fast passive parallel (FPP), and JTAG modes, with optional encryption using AES bitstream protection. The transceiver hard IP integrates pre-emphasis, equalization, and a calibrated termination scheme that simplifies board-level signal integrity work for multi-gigabit serial links. Typical applications include PCI Express Gen1 endpoint and root-complex cards, Gigabit Ethernet / 10 Gigabit Ethernet XAUI line cards, Serial RapidIO bridges for wireless baseband DSP clusters, broadcast video routers, and high-speed serial backplanes in industrial imaging and test equipment. The 780-FBGA package combined with 3.125 Gbps transceivers makes it well suited to mid-complexity protocol bridging designs where designers want FPGA flexibility without paying for full transceiver-rich Stratix-class silicon. When designing with the EP1AGX35DF780C6N, pay close attention to transceiver power filtering, reference-clock jitter, and BGA fanout - the 1.0 mm pitch demands 4 or more PCB layers with microvia technology for cost-effective breakout. Quartus II is the canonical design toolchain; legacy projects may still target the older Quartus II 9.x or 10.x releases because newer Quartus versions have dropped support for this family.
