EP2C8Q208C8 Visão geral
A Cyclone II FPGA belongs to the SRAM-based programmable logic hierarchy: FPGA -> programmable logic device (PLD) -> logic IC -> integrated circuit. Cyclone II sits below Stratix and above MAX in the Altera/Intel portfolio, optimized for high-volume, low-power applications such as digital video, industrial control, and communications glue logic. The 90 nm process delivers a balance between cost, density, and static power that legacy Cyclone designs still leverage today.
Key features of the EP2C8Q208C8 include 36 embedded 18×18 multipliers suited for DSP functions, up to four PLLs for clock management, and dual-purpose configuration pins that double as user I/O after configuration. Maximum internal operating frequency is typically 402.5 MHz, with logic capacity sufficient for glue-logic, bridging, and mid-complexity state-machine designs.
Typical applications for the EP2C8Q208C8 span industrial control boards, video processing front-ends, low-cost PCIe endpoint bridges, legacy telecom line cards, and educational logic-design platforms. The 138 available I/Os comfortably interface to DDR/DDR2 memory, LVDS, and standard parallel buses. Design entry via Altera/Intel Quartus II software ensures access to a mature IP library including Nios II embedded processors.
When designing with the EP2C8Q208C8, ensure proper decoupling (0.1 µF + bulk capacitors per VCCINT/VCCIO bank) and that JTAG chain integrity is maintained for in-system programming. Users migrating from legacy Altera parts should re-validate timing closure in Quartus II, as the design environment has evolved across multiple Quartus releases since this device launched.

Aplicações típicas
EP2C8Q208C8 é adequado para 6 aplicaçãos: Industrial Control and Glue Logic, Digital Video Processing Front-End, Legacy Telecom Line Card Interface, Educational Logic-Design Platform, Low-Cost PCIe Bridge / Endpoint, Automotive Infotainment Test Platform.
Industrial Control and Glue Logic
The EP2C8Q208C8 fits industrial control boards thanks to its 8,256 logic elements and 138 user I/Os. Designers typically instantiate multiple Nios II soft-core variants or custom state machines to replace discrete logic on PLC backplanes and machine controllers. Its 4 PLLs enable precise clock synthesis for CAN, RS-485, and EtherCAT PHYs operating from a single 50 MHz crystal. The commercial 0-85°C temperature range is well-matched to factory-floor enclosures, while the PQFP-208 package simplifies inspection and rework during long-life industrial production runs (10-15 years). Estimated: power consumption is typically <0.5 W for fully utilized 8K LE designs at 1.2 V core, low enough for fanless industrial chassis.
Recomendado
Digital Video Processing Front-End
The EP2C8Q208C8's 36 embedded 18×18 multipliers and 165,888 bits of embedded RAM make it well-suited to digital video front-end tasks such as scaling, de-interlacing, and color-space conversion. Designers typically pair it with an external video ADC and DDR memory, using the 138 I/Os to drive 24-/30-bit RGB buses and ITU-R BT.656 streams. The 4 PLLs synthesize pixel clocks from a single reference, while the Cyclone II fabric supports pipelined DSP blocks for real-time HD processing at 148.5 MHz pixel rates. PQFP-208 is preferred over BGA for prototype video boards since it allows quick hand-rework and oscilloscope probing during signal-integrity debugging.
Recomendado
Legacy Telecom Line Card Interface
The EP2C8Q208C8 continues to serve legacy telecom line-card interfaces where TDM, HDLC, and LVDS bridges must be retained across product generations. With 138 I/Os, designers map T1/E1 framers, serial RapidIO links, and SPI-controlled SLICs into a single device, eliminating multiple CPLDs. The 402.5 MHz fabric frequency accommodates 155 Mbps LVDS and 8B/10B-encoded serial links commonly used in SONET/SDH backplanes. The PQFP-208 package suits through-hole-friendly telecom backplane assemblies and supports hot-socketing required for live line-card insertion during field maintenance.
Recomendado
Educational Logic-Design Platform
The EP2C8Q208C8 is widely adopted in university FPGA laboratories where the Quartus II design flow and the freely-distributable Cyclone II reference designs provide students with a low-cost, real-world programmable-logic learning experience. The 208-pin PQFP package fits low-cost breakout boards with pin headers for breadboard experimentation, and the 8,256-LE capacity is large enough to host student projects ranging from custom RISC-V cores to video-game emulators. The 4 PLLs teach clock-domain crossing, while 36 hardware multipliers introduce DSP concepts without requiring dedicated DSP chips.
Recomendado
Low-Cost PCIe Bridge / Endpoint
The EP2C8Q208C8 is frequently used in cost-sensitive PCIe endpoint bridge designs such as data-acquisition cards, low-cost frame grabbers, and protocol-converter adapters. The Cyclone II hard IP for PCI Express (soft IP available in Quartus II) supports x1 Gen1 operation, and the 138 I/Os expose local buses for SRAM, Flash, and parallel ADC/DAC peripherals. Designers leverage the 36 multipliers for protocol-acceleration CRC engines, achieving >200 Mbps effective throughput on the PCIe link. PQFP-208 enables assembly on standard 4-layer consumer-grade PCBs, keeping BoM cost low for volume peripherals.
Recomendado
Automotive Infotainment Test Platform
Although the EP2C8Q208C8 is rated 0-85°C (commercial), it serves well in automotive infotainment test platforms, prototype head-unit development, and bench-rack validation where production-intent samples are evaluated before transitioning to AEC-Q100-qualified parts. The 138 I/Os interface to MOST, LVDS displays, I2S audio codecs, and CAN-FD controllers, while 36 multipliers accelerate audio DSP and graphic-overlay blending. Engineers use it for proof-of-concept before migrating to Cyclone IV GX or Cyclone V with full automotive qualification; the PQFP-208 simplifies bench rework during iterative bring-up.

Principais diferenciais
- Mature, high-volume production status with broad second-source availability (vs EP2C5Q208C8)
- 138 user I/Os in a PQFP-208 footprint - the largest Cyclone II PQFP variant (vs EP2C8F256C8)
- Industrial-temperature variant (EP2C8Q20818) available as drop-in (vs EP2C8Q208C7)
Notas de projeto
The EP2C8Q208C8 requires multiple power rails: VCCINT (1.2 V core) and VCCIO (1.5/1.8/2.5/3.3 V depending on the I/O bank). Decouple each VCCINT pin with a 0.1 µF ceramic capacitor placed within 5 mm of the pin, plus a bulk 47-100 µF tantalum or polymer capacitor per supply island. Power-on sequencing is not strictly required but is recommended - bring up VCCINT first, then VCCIO banks, to avoid latch-up during hot-socketing. Estimated: total quiescent current at 1.2 V is ~50-200 mA depending on utilization and clock rate.
Lay out the 208-pin PQFP with a continuous ground plane on layer 2 and route signal traces on outer layers, keeping trace lengths matched within ±150 mil for DDR/DDR2 interfaces. Place configuration-mode jumpers (MSEL[3:0]) near the device with 4.7 kΩ pull-ups to VCCIO. JTAG chain signals (TCK, TMS, TDI, TDO) require 10 kΩ pull-ups on TCK/TMS/TDI for reliable boundary-scan operation. The exposed die-attached paddle on the bottom of the PQFP should be soldered to a ground pad for thermal dissipation.
Three common pitfalls to avoid: (1) Do not exceed 3.3 V on any VCCIO bank - exceeding this stresses the I/O drivers and voids the warranty. (2) Always recompile the Quartus II design after changing speed grade (C7 vs C8) - timing models differ slightly. (3) The dual-purpose configuration pins revert to user I/O only AFTER successful configuration - do not rely on them as user I/O until CONF_DONE goes high. Estimate: configuration bitstream size for a fully-utilized 8K-LE design is typically 0.5-1.0 Mbits, requiring 50-100 ms to load from a parallel EPCS flash.
Informações de conformidade
RoHS/REACH/lead-free status not explicitly confirmed in the provided Verified Web Data; [DATA_NEEDED] markers added for these parameters. The EP2C8Q208C8 is not AEC-Q100 qualified - for automotive production use the EP2C8Q208I8N industrial-temperature variant. The C8 speed grade and commercial temperature rating indicate this part targets consumer/industrial (not automotive) applications.
