EP1C12Q240I8ES 概要
An FPGA is an integrated circuit with reconfigurable logic blocks, programmable interconnects, and configurable I/O. Unlike a fixed-function ASIC, an FPGA can implement a new digital circuit by loading SRAM configuration data at power-up. In the system hierarchy, EP1C12Q240I8ES sits inside the broad class of programmable logic devices and more specifically in the FPGA subcategory used when a designer needs custom parallel logic without committing to a custom mask.
Key verified features of the EP1C12Q240I8ES include the 240-terminal FQFP package, Gull Wing terminal form, square QFP body, SRAM-based configuration, and JESD-609 code e0. The Partstack listing for this exact part reports a maximum supply voltage of 1.575 V, consistent with a nominal 1.5-V core design. The device supports device configuration and JTAG boundary-scan testing, as described in the Altera Cyclone FPGA Family Data Sheet.
Because the FPGA fabric is based on SRAM cells, every power-up requires an external configuration source. Designers should include a configuration header or serial configuration device on the same board. The 0.13-um copper process allows the family to integrate a large number of logic elements and memory bits while operating at a low 1.5-V core voltage, which reduces dynamic power compared with older 5-V programmable devices.
Typical applications for this 240-pin Cyclone device include industrial machine-vision preprocessing, custom motor-control PWM generation, FPGA training and prototyping, video capture interfaces, protocol bridging, and test-and-measurement triggering. The industrial temperature code and high pin count make it attractive for control boards that need many parallel I/O signals in a non-temperature-controlled environment.
During board design, pay attention to the 1.5-V core rail and separate I/O supply requirements. Place decoupling capacitors near every VCC pin group, route configuration and JTAG signals to a test header, and verify timing using the Quartus tool for the -8 speed grade. Since this part is discontinued, validate any replacement timing with the same tool before changing the BOM.

主な用途
EP1C12Q240I8ES の用途: 6 件s: Industrial Machine Vision Preprocessing, Industrial Motor Control and PWM Generation, Protocol Bridging and Communication Interfaces, Broadcast Video Capture and Display Control, FPGA Prototyping and Training Boards, Custom Test and Measurement Trigger Logic.
Industrial Machine Vision Preprocessing
The Intel EP1C12Q240I8ES is well suited for industrial machine-vision preprocessing because the Cyclone fabric provides many parallel I/O lanes through the 240-pin PQFP, letting the FPGA capture multiple camera or LVDS byte streams without serializing through a CPU. In this role, the logic implements Bayer color interpolation, simple filters, and frame timing while a host processor executes inference. Because Cyclone is SRAM-based on a 1.5-V 0.13-um process, power is lower than older 5-V FPGA families. The design should include a serial configuration device such as EPCS4SI8N and Quartus timing constraints for the pixel clock. The -8 speed grade is adequate for typical 25 to 50 MHz camera clocks, and the industrial I rating supports machine-vision modules mounted near production lines.

Industrial Motor Control and PWM Generation
EP1C12Q240I8ES can implement multi-axis motor-control PWM, encoder decoding, and fault logic in a single programmable device. Its 240-pin gull-wing QFP package exposes enough general-purpose I/O to connect to isolated gate drivers, current-sense ADCs, and resolver interfaces. In this application, place the FPGA on the control-side logic rail, 1.5 V core plus appropriate VCCIO, not on the high-voltage power stage. Because the Cyclone is SRAM-based, it must be configured by a serial configuration device at power-up; hold configuration pins in reset until the core supply stabilizes. The industrial temperature grade fits servo drives and VFDs in non-conditioned cabinets. Timing closure for 100 kHz PWM dead-time counters is straightforward at speed grade -8.
おすすめ
Protocol Bridging and Communication Interfaces
EP1C12Q240I8ES is useful for protocol bridging in industrial and communications equipment because the FPGA can buffer, translate, or synchronize several parallel or serial interfaces at the same time. The 240-pin package allows connection to Ethernet PHYs, UART transceivers, SRAM, and microcontrollers without expending CPLD resources. In a typical bridge, one side of the FPGA accepts a streaming parallel interface while the other side reads and writes FIFO-like registers; the SRAM-based fabric can be reprogrammed in the field when the protocol changes. Because the device is obsolete, prefer this part for legacy maintenance builds and use a same-family production alternative for new equipment. Keep the configuration device and JTAG header close to the FPGA pins to simplify field updates.
おすすめ
Broadcast Video Capture and Display Control
The Cyclone family architecture of EP1C12Q240I8ES can perform video line buffering, horizontal and vertical timing generation, and pixel-format conversion in hardware. The 240-pin QFP lets designers connect parallel video ADC data buses, external SDRAM, and video DAC outputs without complex multiplexing. The 1.5-V core keeps dynamic power manageable in hot broadcast racks, but board planners should separate the digital FPGA power from the analog video clock domains. The I8ES engineering sample is a poor choice for new production video equipment because of its ES status and tin-lead finish; however, it can recreate the exact timing behavior of legacy video boards. Use an N-suffix production part for RoHS-compliant video assemblies.
おすすめ
FPGA Prototyping and Training Boards
EP1C12Q240I8ES is a practical FPGA for prototyping custom digital logic in university labs and engineering training environments. Its 240-pin FQFP provides enough pins to connect to switches, LEDs, seven-segment displays, and simple memory interfaces, while the Cyclone 1.5-V SRAM architecture teaches modern low-power design methods. Because the part is discontinued, a training board should allow multiple Cyclone EP1C12-Q240 variants to be populated from the same footprint, especially the production I7N or C8N versions. Students can use the JTAG header to download designs directly with a USB-Blaster cable. For low-cost educational boards, package power with a 1.5-V regulator and verify that the FPGA configuration file is reloaded after every board power-up.
おすすめ
Custom Test and Measurement Trigger Logic
EP1C12Q240I8ES can replace fixed timing ASICs in test and measurement instruments by implementing trigger logic, time stamping, and pattern generation in reconfigurable hardware. The 240 I/O pins allow direct connection to comparator banks, high-speed ADCs, and parallel counters. In a digitizer front end, the FPGA controls acquisition windows and data formatting before sending samples to a DSP or PC. Because the exact device is an ES variant, use it for lab validation of a legacy instrument and move to EP1C12Q240I7N for field-service spares. For reliable trigger generation, constrain the internal clock using an external precision oscillator rather than an unregulated internal PLL alone. This reduces cycle-to-cycle jitter in time-interval measurements.

設計ノート
Estimated: Cyclone core current is not given in the verified snippet. For an EP1C12-class design at 1.5 V, use the Quartus PowerPlay report after fitting to estimate Iccint; a common rough range for moderate designs is 300 to 800 mA, but use the fitted report for decoupling selection. Decouple each VCC/VCCIO pin group with 0.1 uF ceramic capacitors and add bulk 10 uF capacitance per supply rail. Keep the 1.5 V core supply below the 1.575 V maximum noted in the Partstack data.
The EP1C12Q240I8ES uses a 240-pin square gull-wing QFP. Use a land pattern that matches the package outline in the Cyclone FPGA Family Data Sheet, because a wrong QFP footprint can cause solder shorts on adjacent fine-pitch leads. Add thermal reliefs on the power planes connected to the package pads. Keep JTAG and configuration traces short and controlled if the design is sensitive to configuration noise.
Always bring TCK, TMS, TDI, TDO, CONF_DONE, and nSTATUS to a header on boards using EP1C12Q240I8ES. Since SRAM-based Cyclone devices need external configuration after power-up, a failed or missing configuration file shows up as a low nSTATUS or CONF_DONE. Add 10k pull-up resistors to CONF_DONE and nSTATUS and place the serial configuration device close to the FPGA configuration pins.
コンプライアンス情報
JESD-609 code e0 in the source data indicates a tin-lead terminal finish, so the ES ordering code is likely not Pb-free. No explicit RoHS or REACH statement was present in the verified web data. The N-suffix alternatives in the Cyclone EP1C12-Q240 family are the lead-free ordering options.
