EP2C5Q208C7N - Cyclone II FPGA, 142 I/O | Altera
The Altera EP2C5Q208C7N is a Cyclone II field-programmable gate array (FPGA) containing 4,608 logic elements, 119,808 bits of embedded RAM, and 142 user I/O pins, housed in a 208-pin BFQFP/PQFP-208 package. It is manufactured on a 90 nm CMOS process with a 1.2 V core supply and is intended for cost-sensitive, high-volume applications that require moderate logic density and predictable timing. A field-programmable gate array is an integrated circuit whose digital logic functions can be configured after fabrication using a hardware description language such as Verilog or VHDL. Unlike a microcontroller, an FPGA implements parallel hardware paths, so control, protocol, and DSP functions can operate simultaneously. In the programmable logic hierarchy, an FPGA belongs to the larger programmable logic device family and is one of the most flexible digital building blocks available, often replacing discrete 74-series logic, CPLDs, ASIC prototypes, and custom state machines. The EP2C5Q208C7N provides several important features for embedded and industrial designs. Its 4,608 logic elements are enough for multi-channel control state machines, bus-interface glue logic, and small image-processing pipelines. The 119,808 bits of embedded RAM support FIFOs, small line buffers, and register-file structures, while the 142 user I/O pins allow direct connection to many ADCs, DACs, sensors, and parallel buses. Datasheets.com lists a maximum internal clock frequency of 402.58 MHz for the device, and the C7 speed grade provides additional timing margin over C8 versions. Altera designed the Cyclone II family to balance performance, density, and cost. The EP2C5 is the smallest mainstream Cyclone II device, offering a practical migration path into higher-density EP2C8, EP2C20, and EP2C35 parts if a design outgrows the available logic and RAM. The 1.2 V core reduces dynamic power compared with earlier 1.5 V or 2.5 V FPGA families, and the commercial 0°C to 85°C operating temperature range covers most indoor and industrial equipment. The 208-pin QFP package provides a convenient board-level footprint without the high layer-count requirements of a fine-pitch BGA. Typical applications include industrial motor-control interfaces, display timing control, protocol bridging between serial and parallel standards, data-acquisition sequencing, and custom glue logic. In each case, the FPGA's parallel execution and deterministic timing improve system responsiveness over software-only alternatives. The embedded PLL and clock-routing resources let designers synthesize several internal clock domains from one external oscillator. When using EP2C5Q208C7N, remember that an FPGA is volatile: configuration data must be loaded from an external EPCS, EPCQ, or JTAG source after power-up. Connect the dedicated MSEL pins to select the intended configuration mode, and provide clean 1.2 V core power with adequate decoupling. The device has no internal flash for permanent program storage, so a configuration memory device should be treated as part of the bill of materials. This page synthesizes distributor inventory, price snapshots, same-family QFP-208 drop-in alternatives, and practical design guidance that are gathered for the EP2C5Q208C7N and are useful for engineers evaluating new or replacement FPGA designs.

It belongs to the Cyclone II family originally introduced by Altera and now supported by Intel, and it is fabricated on a 90 nm process with a 1.2 V core supply. A field-programmable gate array (FPGA) is a semiconductor device containing configurable logic blocks and programmable interconnects that can be reconfigured after manufacturing. In the programmable-logic hierarchy, an FPGA is a type of programmable logic device (PLD), which belongs to the broader category of logic integrated circuits. Unlike a fixed-function ASIC, the EP2C5Q208C8 can implement arbitrary digital logic, from simple state machines to complete processor peripherals, by loading a configuration bitstream at power-up. Key features include 4608 logic elements for combinatorial and sequential logic, 119808 bits of embedded RAM for FIFOs and data buffering, and 142 user I/O pins for connection to multiple logic and interface domains. The C8 speed grade and commercial temperature suffix provide a cost-oriented entry point into the Cyclone II family. The 208-pin BFQFP/PQFP package has accessible perimeter leads, which simplifies PCB layout, soldering inspection, and rework compared with fine-pitch BGA alternatives. Cyclone II architecture is a medium-density FPGA with embedded memory blocks and programmable I/O buffers. The EP2C5Q208C8 can implement soft-core processors, parallel signal-processing datapaths, bus bridges, and controller logic. Its 90 nm process helps balance die cost and power with moderate performance. The 402.58 MHz figure quoted by FPGAkey represents an upper internal clock boundary for speed-grade -8 devices; actual achievable frequency depends on design complexity, synthesis settings, routing, and operating conditions. Typical applications include low-cost motor-control interfaces, sensor aggregation, protocol bridging, video/display processing, and test instrumentation bring-up. The available I/O count allows parallel buses such as 8-bit or 16-bit microcontroller interfaces and multiple encoder inputs to be connected directly. With 119808 RAM bits, internal FIFOs and small frame buffers can be implemented without external memory for many designs. Designers using EP2C5Q208C8 should provide a clean 1.2 V core rail with appropriate decoupling, follow the Intel/Altera power estimation flow in Quartus, and use a supported configuration scheme such as active serial with an EPCS configuration device. Because this -C8 variant is listed as RoHS non-compliant by a distributor, select an N-suffix device for Pb-free assembly or verify an applicable exemption. This page synthesizes verified distributor inventory, current price references, drop-in QFP alternatives, and practical design guidance beyond the manufacturer datasheet, making it useful for legacy maintenance, lifecycle planning, and finding a direct replacement for EP2C5Q208C8.

An FPGA (Field Programmable Gate Array) is a reprogrammable semiconductor device containing an array of configurable logic blocks (CLBs), programmable routing, and embedded memory and DSP resources. FPGAs sit at the top of the digital logic hierarchy alongside ASICs and microcontrollers, but unlike ASICs they can be reconfigured in-circuit to implement arbitrary digital functions, glue logic, state machines, signal processing pipelines, and full soft-processor systems. The Cyclone II family targets low-cost, high-volume applications and uses a 90 nm process with a 1.2 V core. Key features of the EP2C5Q208C8N include 4,608 logic elements, 119,808 RAM bits distributed across M4K blocks (typical block size 4,608 bits), up to 142 user I/O pins, and embedded multipliers (typically 13 per device) for low-cost DSP. The Q208 package (208-pin PQFP) gives ample I/O for parallel buses, memory interfaces, and standard digital peripherals, and supports multiple I/O standards including LVTTL, LVCMOS, PCI, SSTL, and LVDS. Configuration is supported through active serial (AS), passive serial (PS), JTAG, and Fast Passive Parallel (FPP) modes. Architecturally, Cyclone II devices use a logic-element array based on 4-input look-up tables (LUTs) with associated carry and register chains, fed by a multi-level routing fabric. Embedded M4K RAM blocks can be configured as true dual-port, simple dual-port, or single-port memory and support FIFO and shift-register modes. The PLL-based clock management provides up to four phase-locked loops for frequency synthesis and clock-domain alignment. The device operates from a single 1.2 V core supply with separate VCCIO banks for I/O standard flexibility. Typical applications include digital signal processing front-ends, industrial control and factory automation, video processing and display controllers, communication protocol bridging (UART/SPI/I2C to Ethernet or USB), motor control, and educational / hobbyist development platforms. The combination of low unit cost, JTAG-based development, and a free Quartus II design toolchain has made this family a workhorse for low-to-mid density programmable logic. When designing with the EP2C5Q208C8N, allocate adequate decoupling (0.1 uF and 10 uF) near each supply pin, follow Altera/Intel PCB layout guidelines for PQFP packages, and verify the I/O bank VCCIO voltages against your peripheral logic levels. Note that this part is no longer recommended for new designs (NRND) - users should plan migration paths to Cyclone IV or Cyclone 10 LP families.

A Field-Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs), programmable interconnects, and dedicated silicon resources such as block RAM and multiplier blocks. After manufacture, the device is configured by the customer using a Hardware Description Language (HDL) such as Verilog or VHDL, making FPGAs ideal for parallel processing, custom glue logic, and rapid prototyping without the NRE cost of an ASIC. FPGAs sit in the broader taxonomy of digital semiconductors: IC -> programmable logic -> FPGA -> SRAM-based FPGA -> Cyclone II family. Key specifications include 2 PLLs for clock management, 4 clock networks, support for LVDS, LVTTL, PCI, SSTL-2, and SSTL-3 I/O standards, an operating temperature range of -40C to +100C (commercial/industrial grade), and configuration via passive serial, active serial, or JTAG. The Cyclone II architecture also provides dedicated DDR SDRAM interface support, making it suitable for memory-intensive data buffering and video line-store applications. Typical applications include industrial control and motor drives, video processing and display controllers, automotive infotainment, low-cost digital signal processing, communication protocol bridging (UART/SPI/I2C to parallel), and educational FPGA development boards. The 208-PQFP package supports hand-soldering and through-hole-style prototyping workflows, which are less common on newer BGA-only FPGA families. When designing with this device, plan for a 1.2V core supply plus a separate I/O bank voltage, and review the Quartus II (or the supported Quartus Prime 13.0sp1 legacy edition) timing constraints for your clock domains. The 208-PQFP package has higher lead inductance than BGA equivalents, so high-speed LVDS above 640 Mbps may require external termination adjustments.

EP2C5Q208I8N - Cyclone II FPGA 4608 LE, 142 I/O | Intel
The Intel EP2C5Q208I8N is a Cyclone II field-programmable gate array (FPGA) with 4,608 logic elements, 119,808 RAM bits, and 142 user I/Os in a 208-pin PQFP package. It is built on 90 nm CMOS technology, operates from a 1.2 V core supply, and is intended for cost-sensitive digital systems that require flexible logic integration. The package is a 208-pin plastic quad flat pack (PQFP/BFQFP) with a lead-free N suffix finish, and the I8 designator denotes an industrial temperature grade with the -8 speed grade. An FPGA is a semiconductor device containing programmable logic blocks and programmable interconnects that can be configured after manufacturing to implement arbitrary digital circuits. In the broader taxonomy, an FPGA belongs to programmable logic devices, which sit above complex PLDs and CPLDs and below full-custom ASICs. FPGAs provide rapid hardware prototyping, in-field reconfiguration, and parallel processing capabilities that microcontrollers and DSPs cannot match for high-throughput data paths. The EP2C5Q208I8N combines 4,608 logic elements with 119,808 bits of embedded RAM, allowing moderate state machines, FIFOs, and line buffers to be implemented without external memory for small applications. The 142 user I/Os support system-level interfaces such as DDR memory buses, parallel ADCs/DACs, and general-purpose LVCMOS/LVTTL connections. The 90 nm process balances low cost with adequate logic density and power efficiency for industrial embedded systems. The device uses SRAM-based configuration, so external non-volatile configuration memory is required at power-up. A dedicated configuration controller in the Cyclone II architecture loads the bitstream from an EPC-series or third-party serial flash device. The on-chip PLLs provide clock multiplication and phase shifting for the logic fabric, supporting typical system clocking requirements in measurement and communications equipment. Typical applications include industrial machine control, video and imaging pipelines, communication protocol bridging, motor control, test instrumentation, and custom I/O expansion. The 208-pin PQFP package is particularly well suited for boards where low-cost assembly and accessible probing are preferred over fine-pitch BGA packaging. When designing with the EP2C5Q208I8N, pay close attention to the 1.2 V core supply decoupling and the multiple VCCIO bank voltages. A proper power-up sequence and dedicated configuration flash are essential for reliable operation. Because the device is SRAM-based, the configuration bitstream must be reloaded after every power cycle.

The Intel (formerly Altera) Cyclone II EP2C5T144C6 is a low-cost, low-power 90 nm SRAM-based Field Programmable Gate Array (FPGA) housed in a 144-pin LQFP (also referred to as 144-TQFP) package. According to distributor listings, the device integrates 4,608 logic elements (LEs), 119,808 RAM bits, 13 embedded 18x18 multipliers, and supports up to 89 general-purpose user I/O pins, making it a popular choice for cost-sensitive digital logic, glue-logic, and DSP-front-end designs introduced in the late-2000s era. The 'C6' speed grade indicates a commercial temperature range (0C to +85C) with the standard (non-fastest) speed bin, while the 'I7' or 'C8' speed grades offer higher performance where available. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit that can be electrically reconfigured after manufacture to implement arbitrary digital logic. In the system hierarchy FPGAs sit alongside ASICs, microcontrollers, and DSPs as reprogrammable compute fabric, but are distinguished by their parallel architecture, deterministic timing, and ability to host custom high-speed serial, memory, or processor cores. The Cyclone II family was Intel/Altera's second-generation low-cost FPGA line, succeeded by Cyclone III, Cyclone IV, and Cyclone V (now with embedded ARM cores). It remains widely deployed in long-lifecycle industrial, industrial-automation, and educational designs, and is frequently the lowest-cost way to obtain a genuine FPGA from authorized channels. Key features of the EP2C5T144C6 include 4,608 LEs, two on-chip PLL blocks for clock synthesis, 13 dedicated 18x18 hardware multipliers (capable of approximately 50-150 MHz DSP throughput depending on routing), 119,808 bits of embedded M4K memory, support for LVDS, LVTTL, LVCMOS, PCI, SSTL-2/H, and other I/O standards, and configuration via JTAG or Active Serial (AS) modes.

Typical applications include industrial motor control, video processing front-ends, software-defined radio (SDR) baseband, educational FPGA development boards (DE1/DE2), low-volume ASIC prototyping, and consumer-electronics glue logic. The 144-TQFP package is a low-cost plastic surface-mount package compatible with hand-soldering and low-cost PCB assembly lines. When designing with the EP2C5T144C6, ensure the Quartus II design software (13.0sp1 or earlier; Quartus Prime does not support Cyclone II) is used for synthesis, place-and-route, and timing closure. Designers should observe banked I/O supply constraints, use proper decoupling (100 nF per supply pin plus bulk capacitors), and respect the 1.2 V core-rail tolerance of +/-5%. This page synthesizes distributor pricing, drop-in same-package alternatives (EP2C5T144C7, EP2C5T144C8, EP2C5T144I6, plus 144-pin-compatible family members), and practical design notes not always obvious from the Cyclone II Device Handbook alone.

Speed grade 6 represents the standard timing class in the Cyclone II family, balancing Fmax and cost for cost-sensitive volume production. Operating at 1.15V-1.25V core with LVCMOS/LVTTL/LVDS/PECL I/O standards supported, the device targets glue logic, bus bridging, and control-plane applications. A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose digital logic functionality is defined after manufacturing by the customer, via a configuration bitstream. FPGAs sit in the broader taxonomy: programmable logic device (PLD) -> FPGA -> SRAM-based FPGA -> Cyclone II family. They differ from ASICs by offering rapid prototyping, field re-programmability, and lower NRE cost, while trading off per-unit cost and absolute performance against fixed-function ASICs. Cyclone II is positioned in the low-density, low-power tier below the Cyclone III/IV/V families. Key features include up to 89 user I/O pins across 4 I/O banks, embedded 18x18 multipliers (13 total) for DSP-style arithmetic, dual-purpose configuration pins, and JTAG boundary-scan (IEEE 1149.1) for in-system programming and boundary test. The device supports multiple configuration modes including AS, PS, JTAG, and FPP, enabling flexible boot from EPCS serial flash or microprocessor hosts. The 144-pin LQFP package is plastic and surface-mount with 0.5mm pitch, suited to standard SMT assembly lines without requiring BGA-grade inspection. Cyclone II FPGAs use a logic element (LE) granularity built around 4-input look-up tables (LUT4), each with an associated carry chain and register. The M4K embedded RAM blocks (13 blocks of 4,608 bits each) deliver true dual-port operation up to 250 MHz and can be configured as RAM, ROM, or FIFO buffers. Phase-locked loops (PLLs) provide clock multiplication, division, and phase shifting across the 2-4 PLLs available per device. Typical applications include industrial motor control front-ends, low-density protocol bridges (UART/SPI/I2C to Ethernet), LED display controllers, video processing front-ends, educational development boards, and low-cost DSP pipelines. The Cyclone II is well-suited to designs where pin count and logic density demand exceed microcontrollers but ASIC NRE cannot be amortized. When designing, plan for JTAG access (TCK/TMS/TDO/TDI pulled appropriately), 2.5V/3.3V bank voltage compatibility, decoupling per power pin, and configuration storage via EPCS1/EPCS4 serial flash. The LQFP-144 package benefits from generous copper pours and routed differential pairs for LVDS signals where jitter budget matters. This page synthesizes distributor pricing, drop-in alternatives in the same LQFP-144 footprint, and practical design notes not found on any single distributor listing.
EP2C5T144C7 - Cyclone II FPGA, 4,608 LEs, 144-LQFP | Intel
The Intel (formerly Altera) EP2C5T144C7 is a low-cost Cyclone II Field-Programmable Gate Array (FPGA) built on a 90 nm CMOS process, delivering 4,608 logic elements, 119,808 RAM bits, and 89 user I/O pins in a 144-pin TQFP (T144) package. The device operates from a 1.2 V core supply with 3.3 V LVCMOS/LVTTL I/O support and is offered in the commercial speed grade 7 tier targeting general-purpose logic, glue replacement, and parallel DSP preprocessing tasks. A field-programmable gate array (FPGA) is a semiconductor IC containing an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard IP such as block RAM and multipliers, all controllable by an SRAM-based configuration bitstream. FPGAs sit in the broader taxonomy of programmable logic devices (PLD), above simple CPLDs and below ASICs in cost-per-volume but well above microcontrollers in raw parallel throughput. Cyclone II specifically targets the low-power, low-cost end of the FPGA market introduced in 2004 to displace ASICs in volume consumer and industrial designs. Key features include 13 embedded 18x18 multipliers suitable for DSP workloads, four phase-locked loops (PLLs) for clock management, support for external memory interfaces including DDR/DDR2 SDRAM and QDRII SRAM, and a 1.2 V core with multi-voltage I/O banks. Configuration is loaded from serial or parallel flash, JTAG, or Altera/Intel Quartus II software. The part is non-volatile in the sense that the configuration must be reloaded after each power-up since the SRAM cells are volatile. The Cyclone II architecture uses four-input look-up tables (LUTs) per logic element, embedded M4K RAM blocks (each 4 Kbit plus parity), and a hierarchical routing fabric. The 90 nm process gives a balance of leakage and performance suitable for fanless industrial enclosures; maximum internal clock frequency for this speed grade is in the hundreds of MHz for typical paths, and design tools report fMAX figures in the device handbook rather than on a single datasheet page. Typical applications include industrial control and human-machine interface panels, video processing front-ends, low-cost motor control, glue logic bridging microcontrollers to parallel peripherals, and education kits where Quartus II support and a free Web Edition toolchain lower the entry barrier. The 144-pin TQFP footprint is also breadboard-friendly, which makes the part popular in university digital-design labs and prototype boards. When designing with this device, plan the power budget around the 1.2 V core current (which scales with logic utilization and toggle rate) and the 3.3 V I/O current, and place decoupling capacitors within 5 mm of each supply pin per the Cyclone II Handbook pin connection guidelines. Use Quartus II 13.0sp1 or 13.1 (the last release supporting Cyclone II) for synthesis; later Quartus versions have dropped Cyclone II device support. This page synthesizes distributor stock, drop-in same-family Cyclone II alternatives, and practical design notes not found in the manufacturer datasheet alone, giving engineers a single reference for the EP2C5T144C7 in current designs.

The part ships in a 144-LQFP package with 20 × 20 mm body, 0.5 mm pitch, surface-mount compatible. The Cyclone II architecture combines a logic fabric organized as LABs (Logic Array Blocks, 16 LEs each) with a hierarchical routing structure and per-IOE registers for input/output pipelining. Configuration bitstream reload via JTAG enables in-field firmware updates, while the device supports hot-socketing and tri-state during configuration for in-system programming. Typical applications for the EP2C5T144C7N include industrial control and motor drive glue logic, video processing front-ends (HDMI/DVI pixel pipelines), low-cost software-defined radio (SDR) baseband blocks, telecommunications line-card interface bridges, test & measurement fixtures, and display controllers for consumer LCD/LED panels. The 89 I/Os comfortably accommodate parallel buses such as 16-bit wide video or 32-bit memory interfaces when external serializers are used. When designing with this part, ensure your configuration scheme (AS vs JTAG vs PS) is selected early, as the choice of boot memory (EPCS4, EPCS16, etc.) determines board cost. Decoupling follows Altera's PDN guidance: bulk 100 µF + 10 µF + 0.1 µF per supply rail. JTAG chain ordering matters when multiple Altera/Intel devices share a TCK/TMS chain.
EP2C5T144C8 - Cyclone II FPGA, 4,608 LEs, 89 I/O, 144-TQFP | Intel
The Intel (formerly Altera) EP2C5T144C8 is a low-cost, low-power Cyclone II Field-Programmable Gate Array (FPGA) delivering 4,608 logic elements, 119,808 RAM bits, and 89 user I/Os in a 144-pin TQFP package. Built on TSMC's 90 nm low-k dielectric process, the device operates at 1.2 V core with 8 ns speed grade and is offered in commercial temperature grade (0 C to +85 C). The Cyclone II family was designed to replace ASICs in cost-sensitive high-volume applications while keeping power consumption below legacy FPGA families. A Field-Programmable Gate Array (FPGA) is a semiconductor integrated circuit composed of configurable logic blocks (CLBs), programmable interconnects, and dedicated hard-IP blocks (DSP slices, block RAM, PLLs, transceivers) that the designer programs after manufacture. FPGAs sit at the top of the programmable-logic hierarchy alongside CPLDs and mask-programmed ASICs, and below them in system complexity sits the microcontroller. The Cyclone II generation occupies the low-end position in the FPGA taxonomy, prioritising logic density per dollar over raw performance. Key features of the EP2C5T144C8 include embedded 18 x 18 multipliers (total of 13 for the EP2C5 row), M4K block RAM columns, dual-purpose PLL clock management, and support for external memory interfaces such as DDR/DDR2 SDRAM and QDRII SRAM. The 144-pin TQFP (T144) is a plastic thin quad flat pack that supports 89 user I/Os at a 22 x 22 x 1.4 mm body size and is suitable for conventional SMT assembly lines. The Cyclone II architecture is built around four-input look-up tables (LUTs), true dual-port M4K RAM blocks with parity, and dedicated DSP blocks for 18-bit signed multiplication. Configuration is loaded from an Altera serial configuration (EPCS) device or via JTAG, with built-in decompression and encryption support. Compared with the original Cyclone, Cyclone II roughly doubles logic density and adds hardware multipliers, making it a strong fit for digital signal processing front ends that previously required a separate DSP chip. Typical applications include digital signal processing (Dsp) front ends for video, image, and audio pipelines; industrial control and motor drive logic; communications protocol bridging (SPI, I2C, UART, PCIe soft cores); and consumer electronics that need glue logic and parallel processing under tight BOM cost. The 1.2 V core combined with low static current also makes the EP2C5T144C8 suitable for portable battery-powered embedded designs where power budget matters. When designing with the EP2C5T144C8, plan I/O bank assignments to keep differential pairs (LVDS) on dedicated pins and respect the VCCIO bank voltage (typically 3.3 V for legacy interfaces, 1.8 V for DDR). Quartus II software handles place-and-route; for new designs consider migrating to a Cyclone IV or Cyclone 10 LP equivalent because Cyclone II is at end-of-life and supply is increasingly limited to authorized distributors and the secondary market. This page synthesises verified distributor pricing, drop-in same-package alternatives sourced from the Cyclone II family and authorised Altera-Intel listings, and practical design notes that are not contained in the bare datasheet.
EP2C5T144C8N - Cyclone II FPGA 4,608 LEs 89 I/O 144-TQFP | Intel
The Intel (formerly Altera) EP2C5T144C8N is a low-cost Cyclone II Field Programmable Gate Array (FPGA) housed in a 144-pin TQFP (T144) package measuring 22x22 mm. Built on TSMC's 90 nm low-k dielectric process, the device delivers 4,608 logic elements, 119,808 bits of embedded M4K RAM, 13 dedicated 9x9 multipliers, 89 user I/Os and 2 PLLs running with a 1.15 V to 1.25 V core supply at speed grade 8. An FPGA (Field-Programmable Gate Array) is a programmable logic device (PLD) — a category of semiconductor IC that sits between an ASIC and a CPLD in the programmable logic hierarchy: ASIC < PLD < CPLD < FPGA. Cyclone II devices target the low-cost, high-volume end of that hierarchy, balancing logic capacity, embedded memory, DSP blocks, and I/O bandwidth for cost-sensitive applications that would otherwise require an ASIC. Key features include 4,608 logic elements, 119,808 RAM bits organized in M4K blocks, 13 embedded 18x18 (9x9 mode) multipliers, two general-purpose PLLs, support for DDR/DDR2/QDRII SRAM and LVDS I/O standards, and an on-chip configuration controller supporting serial, parallel, and JTAG configuration modes. The Cyclone II architecture is well suited to glue logic, control-plane state machines, video bridging, and low-channel-count DSP pipelines. The 90 nm process and 1.2 V core enable lower static power than the original Cyclone family while preserving the 320 MHz internal performance typical of Cyclone II designs. The 144-pin TQFP package exposes 89 user I/Os with support for single-ended standards such as LVTTL, LVCMOS, SSTL, and PCI, plus LVDS pairs — sufficient for parallel buses, video interfaces, and DDR memory controllers. Typical applications include industrial control, video surveillance and image processing front-ends, motor and inverter control, telecom line cards, low-cost ASIC prototyping, and educational FPGA development boards. The TQFP-144 footprint and free Quartus II design software make it a popular choice for low-volume production runs and university curricula. When designing with this part, ensure all VCCINT, VCCIO, and PLL analog supply pins are decoupled with 0.1 µF and 10 µF capacitors placed within 5 mm of the package. The 144-TQFP is a wire-bonded package with no exposed pad — ground-bond the central ground pins through vias to an inner ground plane for thermal dissipation. Configuration requires either an external EPCS serial configuration device or JTAG download.

An FPGA (Field-Programmable Gate Array) is a programmable logic device whose logic fabric, interconnect, and I/O behavior are defined by a user-loaded configuration bitstream. In the system hierarchy, FPGAs sit between fixed-function ASICs and software-driven microcontrollers, offering hardware-level parallelism with design-time flexibility. The Cyclone II family specifically targets the low-power, high-volume cost band between CPLDs and high-end FPGAs, originally introduced in 2004 as Altera's response to Xilinx Spartan-3. Key features include up to 500 MHz internal operation, dedicated hardware multipliers for DSP pipelines, support for external memory interfaces including DDR/DDR2/QDRII SDRAM, and a 4-wire serial configuration interface (AS, PS, or JTAG modes). The 896-FBGA package provides high I/O density for parallel bus implementations and high-speed external memory connections. Typical applications include digital signal processing front-ends, video processing pipelines, industrial machine vision, motor control, soft-core processor implementations (NIOS II), and communications protocol bridging. Designers appreciate the strong balance between logic density and unit cost that this part historically delivered. When designing with this device, ensure the FPGA configuration scheme (active serial versus JTAG) is selected up-front, and verify that the board layout supports the 896-ball FBGA ball pitch with adequate breakout routing.

EP2C70F896C6N - 68K LE Cyclone II FPGA, 896-BGA | Intel
The Intel (formerly Altera) EP2C70F896C6N is a high-density Cyclone II family Field-Programmable Gate Array (FPGA) housed in a 896-ball FineLine BGA package. The device integrates 68,416 logic elements, 250 M4K RAM blocks totaling approximately 1,152,000 bits of embedded memory, and 622 maximum user I/O pins, fabricated on a 90 nm low-k CMOS process. It is specified for commercial temperature operation (0C to +85C) and is supplied in lead-free (Pb-free) packaging. An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs) connected by a programmable interconnect fabric. FPGAs occupy the highest tier of the digital logic hierarchy: gate array -> programmable logic device (PLD) -> complex programmable logic device (CPLD) -> FPGA -> SoC FPGA. Unlike microcontrollers that execute firmware sequentially, FPGAs implement true hardware parallelism, making them ideal for high-throughput DSP, custom interfacing, and prototyping ASICs. The Cyclone II family targets cost-sensitive, high-volume applications where ASIC NRE costs cannot be justified. Key features of the EP2C70F896C6N include 4,276 configurable logic blocks (CLBs), up to 150 embedded 18x18 multipliers, four phase-locked loops (PLLs) for clock management, and support for external memory interfaces including DDR, DDR2, SDR, and QDRII SRAM. Configuration is loaded via passive serial (PS), active serial (AS), or JTAG modes, with configuration data stored in an external serial configuration device. The architecture combines a four-input look-up table (LUT)-based logic element with embedded memory and multiplier blocks, allowing designers to balance logic, RAM, and DSP resources on a per-design basis. The 622 user I/O pins are organized into eight I/O banks, each supporting a mix of single-ended standards (LVTTL, LVCMOS, PCI, SSTL) and differential standards (LVDS, RSDS, mini-LVDS) at user-selectable voltages. Typical applications include industrial motor control and video processing, telecommunications line cards, automotive driver assistance prototypes, and educational or research platforms. The high logic density makes it well suited to mid-range ASIC prototyping and signal processing pipelines. The 896-ball BGA package, however, requires multi-layer PCB design and controlled-impedance routing, increasing board complexity. When designing with this device, pay close attention to the four PLL placement constraints: each PLL must reside in a corner of the die and supports only specific clock input pins. Thermal dissipation is moderate for an FPGA of this size, but designers should plan copper pour and thermal vias for production environments where ambient temperature may exceed 70C.
