EP1C12Q240C7 概要
An FPGA is a programmable logic device that lets engineers implement arbitrary digital circuits through configuration of an array of logic elements (LEs), embedded memory blocks, and routing resources, all hardwired as a sea of gates. FPGAs sit between discrete TTL/CMOS glue logic and ASICs: faster to market than ASICs, far more flexible than fixed-function CPLDs, and capable of running parallel hardware tasks (DSP, packet processing, video pipelines) that microcontrollers execute sequentially at lower throughput. Cyclone-class FPGAs specifically target the low-power, low-cost segment where the legacy gate-array style programmable logic was previously over-spec'd.
Key features of the EP1C12Q240C7 include four Phase-Locked Loops (PLLs) for clock synthesis and skew management, dedicated 18x18 hardware multipliers for fixed-point DSP, dual-purpose configuration pins that can serve as user I/O after configuration, support for LVTTL, LVCMOS, SSTL, and LVDS I/O standards, and 239,616 bits of M4K embedded memory arranged as true dual-port or single-port blocks. The 240-pin PQFP package is surface-mountable but uses 0.5 mm pitch gull-wing leads, which is unusual for modern fine-pitch BGA-class parts but acceptable for hand-prototyping and moderate-density production runs.
Typical applications include industrial control and factory automation controllers, telecom line-card glue logic and protocol bridging, video processing front-ends and image preprocessing pipelines, software-defined radio baseband preprocessing, and legacy parallel-bus extension for microprocessors. The Cyclone architecture is supported by the Quartus II design suite (legacy versions 6.0 through 13.0sp1 are still widely used) and the part is mature enough that reference designs, IP cores, and HDL examples are abundant in the public domain.
Designers should note that this part is in long-term mature status - new designs targeting EP1C12Q240C7 should evaluate Cyclone IV (EP4CE) or Cyclone V (5CE) families for active long-term support, but existing boards can still be maintained and re-spun using the original part. Configuration memory is volatile SRAM, so an external configuration device (EPCS1/EPCS4 or compatible flash) is required at every power-up.

主な用途
EP1C12Q240C7 の用途: 6 件s: Industrial Control & Factory Automation, Telecom Line-Card Glue Logic, Video Processing Front-End, Software Defined Radio Baseband, Legacy Parallel Bus Extension, Motor Control & Power Conversion.
Industrial Control & Factory Automation
The EP1C12Q240C7 fits industrial control cabinets thanks to its 12,060 logic elements and 173 user I/O, which comfortably absorb encoder counting, PWM generation, and parallel bus glue logic that bridges PLC backplanes to stepper/servo drivers. With four PLLs it can synthesize independent clock domains for CAN, RS-485, and EtherCAT PHYs from a single 50 MHz crystal, eliminating multiple oscillators on the BOM. The BFQFP 240-pin package is hand-solderable for prototype retrofits and supports the 0C to 85C commercial range used in climate-controlled enclosures.
おすすめ
Telecom Line-Card Glue Logic
The EP1C12Q240C7 is well suited to telecom line cards where it implements TDM bus aggregation, framing/deframing, and protocol bridging between backplane SERDES and payload processors. Its 52 dedicated 18x18 hardware multipliers handle A-law/u-law companding and small FIR filters without burning general-purpose LEs. The 239,616 bits of M4K RAM act as elastic buffers and rate-matching FIFOs between asynchronous clock domains. Hot-swap and JTAG support enable in-system reconfiguration during card insertion, and the 240-pin PQFP gives test-fixture access for ICT coverage.
おすすめ
Video Processing Front-End
The EP1C12Q240C7 is used as a video front-end for capture cards, performing BT.656/BT.1120 decoding, color-space conversion, deinterlacing, and OSD overlay before pushing pixels to a DSP or SoC. Its 173 I/O pins allow parallel 16-bit ITU-R BT.656 input plus 24-bit RGB output plus control signals, all at 27-148.5 MHz pixel rates. The dedicated 18x18 multipliers accelerate 3x3 convolution kernels for sharpening or chroma filtering. M4K RAM blocks store line buffers with simple dual-port access, eliminating external SRAM in cost-sensitive designs.
おすすめ
Software Defined Radio Baseband
In SDR baseband preprocessing, the EP1C12Q240C7 implements digital down-conversion (DDC), decimation filters, and channelizer logic between a high-speed ADC and a host processor. Its PLLs synthesize coherent sample clocks from a TCXO reference, while the 52 hardware 18x18 multipliers execute CIC and FIR compensation filters at baseband sample rates up to ~100 MHz. The 173 I/O pins accept parallel LVDS ADC data plus reference clock and sync, making it a cost-effective alternative to dedicated DSP chips for moderate-channel-count receivers in commercial wireless infrastructure.
おすすめ
Legacy Parallel Bus Extension
The EP1C12Q240C7 serves as a bridge between modern SoCs and legacy 8/16-bit parallel peripherals such as ISA cards, VME bus, PC/104 modules, or proprietary DSP interfaces. With 173 user I/O it can implement a full 16-bit data bus plus 24-bit address plus control signals in a single chip, replacing 4-6 legacy bus-driver PLDs. The Quartus II design flow lets engineers instantiate bus arbiters, wait-state generators, and interrupt controllers as IP cores. Volatile SRAM configuration is acceptable since the device is permanently mounted on a production board.
おすすめ
Motor Control & Power Conversion
The EP1C12Q240C7 handles Field-Oriented Control (FOC) and Space Vector PWM (SVPWM) for three-phase motor drives and solar inverters, where deterministic timing and parallel processing outperform microcontrollers. Its PLLs multiply a low-frequency crystal up to multi-MHz PWM carrier rates, while 52 dedicated multipliers execute Park/Clarke transforms and PI controllers in real time. The 173 user I/O drive gate-driver enable signals, brake control, and ADC sampling triggers, and the BFQFP package dissipates heat adequately for switching frequencies up to ~50 kHz with reasonable dead-time insertion.

設計ノート
Estimated: at 100% LE utilization with 173 I/O toggling at 100 MHz, the EP1C12Q240C7 core draws roughly 0.6 A from VCCINT (1.5 V) plus 0.2-0.5 A per VCCIO bank depending on switching frequency and load. Decoupling must use a 100 uF bulk + 0.1 uF X7R per power pin pair, placed within 5 mm of the pin. Use a separate 1.5 V regulator for VCCA (PLL analog supply) with a ferrite bead filter from VCCINT to suppress switching noise on the PLL reference.
The 240-pin BFQFP at 0.5 mm pitch requires 4-layer PCB minimum with continuous power and ground planes for return-current integrity. Fanout from perimeter pads to inner layers should use 0.15 mm (6 mil) traces with 0.2 mm (8 mil) spaces to maintain impedance control. Place an EPCS1/EPCS4 configuration flash within 50 mm of the FPGA DATA0/DCLK/nCONFIG pins to avoid configuration failures; longer traces need series termination.
MSEL[2:0] configuration-mode pins must be tied to VCCIO or GND through 1 kohm resistors and never left floating, or the device may enter an undefined configuration state. CONF_DONE must be pulled up to VCCIO via 10 kohm; nSTATUS must be pulled up to VCCIO via 10 kohm; nCONFIG requires an external pull-up plus a momentary push-button or supervisor to trigger reconfiguration. Volatile SRAM means the design is lost at every power-down - an EPCS flash is mandatory for stand-alone boot.
The 240-BFQFP package has a theta_JA of approximately 25 C/W (estimated for JEDEC EIA/JESD51 4-layer test board with airflow). At 1.5 W total dissipation, junction temperature rises ~38 C above ambient, leaving safe headroom within the 0C to 85C commercial range. For sealed enclosures, derate by 0.5 C/W per side and consider adding 100 cm^2 of copper pour on top side or thermal vias to inner ground plane.
コンプライアンス情報
Original Cyclone I PQFP parts are typically SnPb-finished and not RoHS-compliant; the 'N' suffix variants are lead-free. RoHS and lead-free status of this exact lot must be verified with the supplier. AEC-Q100 is not applicable for this commercial-grade FPGA; the I7 industrial variant is also not AEC-Q100 qualified for automotive use.
