EP1C12Q240C8N Présentation
An FPGA (Field-Programmable Gate Array) is a reconfigurable semiconductor whose logic fabric, interconnect, and I/O can be programmed by the designer after manufacture. FPGAs sit above ASICs and microcontrollers in the digital logic hierarchy (FPGA -> programmable logic device -> reconfigurable logic -> semiconductor), enabling parallel hardware implementation of DSP pipelines, state machines, bus bridges, and interface protocols without the NRE cost of an ASIC. The Cyclone family specifically positioned itself as a low-cost, low-power alternative to APEX and Stratix families for high-volume, price-driven designs.
Key features of the EP1C12Q240C8N include 12,060 logic elements, 239,616 bits of embedded RAM organized in M4K blocks, two PLL-based clock management blocks, support for LVDS I/O at up to 640 Mbps, and a maximum of 173 user I/O pins in the 240-pin PQFP package. The device supports multiple configuration schemes including Active Serial (AS), Passive Serial (PS), and JTAG-based programming, and is supported by the Altera Quartus II design toolchain.
The Cyclone architecture uses 4-input look-up tables (LUT4) per logic element, dedicated carry chains for arithmetic, and embedded multiplier blocks for DSP workloads. The 0.13 µm process combined with 1.5 V core operation reduces power versus the earlier APEX 20K and ACEX 1K families while keeping dynamic performance adequate for 66-133 MHz PCI and SDRAM controller applications. The two PLLs provide clock multiplication, division, and phase shifting for multi-clock domain designs.
Typical applications include industrial automation controllers, telecom line cards, video processing front-ends, legacy PCI/PCI-X bus bridges, motor control, data acquisition systems, and replacement of multiple discrete glue-logic ICs with a single programmable device. The 240-pin PQFP package also makes it suitable for through-hole-friendly prototyping and hand-solderable designs.
When designing with this part, ensure that the Quartus II fitter has been updated to the latest service pack for Cyclone device support, and verify that the chosen configuration memory (EPCS1/EPCS4) matches the bitstream size. Designers should also confirm that the I/O assignments fit within the 240-pin PQFP pin map and that the LVDS pairs are routed on dedicated true-differential pin pairs per the pinout file.
This page synthesizes distributor pricing snapshots, drop-in same-family Cyclone I alternatives, and practical Quartus II design considerations that are not always covered in a single datasheet chapter.

Applications typiques
EP1C12Q240C8N convient pour 6 applications: Industrial Automation and Motor Control, Legacy PCI / PCI-X Bus Bridge, Video Processing Front-End, Telecom Line Card Glue Logic, Data Acquisition System Controller, Legacy FPGA Maintenance and Replacement.
Industrial Automation and Motor Control
The EP1C12Q240C8N's 12,060 logic elements and two PLLs make it well suited for industrial motor-control and PLC-style automation. Its M4K memory blocks can buffer quadrature encoder streams, while the 240-pin PQFP package keeps PCB layout accessible for hand-soldered prototypes in factory-floor equipment. The Cyclone I fabric delivers predictable timing for closed-loop PID controllers, BLDC commutation tables, and EtherCAT/CANopen slave bridges. Industrial designs benefit from the part's PCI-compatible I/O and ability to integrate multiple 16-bit timer/counter channels in a single chip, reducing BOM complexity in motor-drive boards.
Recommandé
Legacy PCI / PCI-X Bus Bridge
The Cyclone I 240-pin PQFP variant was widely adopted in PCI 32-bit/33 MHz and PCI-X add-in card designs, where the 12,060 LEs accommodate full Target and Master state machines plus FIFOs. The EP1C12Q240C8N's 173 user I/O pins allow direct connection to the 32-bit PCI bus plus side-band signals, while the M4K blocks implement the elastic transmit/receive FIFOs. The 1.5 V core with 3.3 V PCI I/O is natively supported via the bank's VCCIO pins. Designers can use the part to bridge legacy PCI hosts to modern I/O such as Gigabit Ethernet or USB, extending the service life of installed industrial PCs.
Recommandé
Video Processing Front-End
The EP1C12Q240C8N's M4K RAM blocks serve as line buffers for video pipelines, while 12,060 LEs handle color-space conversion, deinterlacing, and on-screen display overlays. The 240-pin PQFP package exposes enough LVDS-capable pins for parallel RGB or ITU-R BT.656 video interfaces. The two PLLs generate pixel clocks from a 27 MHz reference, supporting standard-definition to high-definition frame rates. Cyclone I is a proven choice for entry-level broadcast equipment, security DVR front-ends, and industrial machine-vision cameras where 0.13 µm fabric cost-effectiveness matters more than cutting-edge DSP performance.
Recommandé
Telecom Line Card Glue Logic
The 12,060 LE Cyclone I fabric in PQFP-240 is ideal as glue logic on telecom line cards: bus muxing, TDM time-slot switching, E1/T1 framer interfacing, and low-density HDLC controllers all fit comfortably. The two PLLs provide per-card clock synthesis, while 173 user I/O connect to backplane buses, framers, and serializers. The obsolete-but-available stock profile makes the EP1C12Q240C8N a stable platform for maintaining installed legacy central-office equipment where re-qualification of newer FPGAs would be cost-prohibitive. Quartus II supports the LVDS and LVTTL signaling needed for telecom backplanes.
Recommandé
Data Acquisition System Controller
For multi-channel data-acquisition boards, the EP1C12Q240C8N's 173 user I/O pins handle parallel ADC interfaces, digital isolation barriers, and trigger logic. The M4K RAM blocks implement circular sample buffers for transient capture, while the PLLs derive ADC sampling clocks from a master reference. Engineers use Cyclone I in PQFP for vibration monitoring, power-quality analyzers, and ultrasound front-ends. The 240-pin PQFP is hand-solderable, easing prototyping of low-volume industrial and medical DAQ boards, and the 12,060 LEs permit embedded Nios I or Nios II soft-core processors for on-board control.
Recommandé
Legacy FPGA Maintenance and Replacement
The EP1C12Q240C8N serves as a maintenance-of-supply part for installed OEM equipment originally built on Cyclone I. When original production boards reach end-of-life, the EP1C12Q240C8N (or its speed-grade siblings C6N/C7N/C8) provides a like-for-like replacement without requiring PCB redesign. The 240-pin PQFP footprint remains compatible across all speed-grade variants, and the Quartus II toolchain preserves bitstream backward compatibility. Industrial and medical OEMs use this strategy to extend the service life of certified equipment, avoiding costly re-qualification cycles.

- Fastest speed grade option in same footprint (vs EP1C12Q240C6N)
Notes de conception
Place all decoupling capacitors (0.1 µF ceramic plus 33 µF tantalum or polymer bulk) within 100 mils of every VCCINT and VCCIO pin on the EP1C12Q240C8N. Use a solid VCC and GND plane on adjacent layers; the 240-pin PQFP at 0.5 mm pitch requires four-layer PCB minimum to maintain signal-integrity for LVDS and 66 MHz PCI signals. Each PLL power pin (VCCA_PLL) needs its own pi-filter (ferrite bead plus 10 µF and 0.1 µF). The JTAG chain (TCK/TMS/TDO/TDI) should be pull-up terminated per IEEE 1149.1 and routed with stub length under 1.5 inches.
Do not confuse the EP1C12Q240C8N (PQFP-240) with the EP1C12F324C8N (FBGA-324); both are Cyclone I 12,060-LE parts but they are NOT pin-compatible. Migration between them requires a PCB redesign and Quartus II pin reassignment. Also avoid mixing MSL (Moisture Sensitivity Level) handling: PQFP-240 packages typically ship at MSL 3 and require bake-out before reflow if the sealed bag is opened beyond the floor-life specified on the moisture-barrier label. Always verify the device date code against the Altera/Intel PCN (Product Change Notification) database before qualifying a new lot.
The 240-pin PQFP uses 0.5 mm pitch gull-wing leads; recommended land patterns per IPC-7351 nominal density are 0.30 mm wide pads with 0.10 mm solder-mask sliver. Use a 0.15 mm stencil thickness for reflow to avoid solder bridging on fine-pitch leads. The exposed die-attach pad is not present on the PQFP variant (unlike FBGA), so thermal management relies on copper pours on the top and bottom layers connected by 0.3 mm thermal vias in a 1.0 mm grid. Power estimation should use the Quartus II PowerPlay Early Power Estimator spreadsheet before final design closure.
