EP2C5Q208I8 概要

The Intel (formerly Altera) EP2C5Q208I8 is a low-cost Cyclone II Field-Programmable Gate Array (FPGA) housed in a 208-pin Plastic Quad Flat Pack (PQFP/BFQFP) package with 142 user I/O pins. Built on a 1.2V, 90 nm CMOS process, it integrates 4,608 logic elements, 119,808 memory bits distributed across 26 M4K RAM blocks, and 13 embedded 18x18 multipliers, giving designers a balanced mix of logic, memory, and DSP resources for cost-sensitive applications.

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.

Automotive Infotainment and Body Electronics

Within automotive infotainment and body-electronics modules, the EP2C5Q208I8 serves as a flexible I/O expansion and protocol-bridging device between microcontrollers, MOST or CAN buses, head-unit displays, and audio codecs. Its 142 user I/O pins absorb the multiple voltage domains (1.8V, 3.3V, 5V) used in legacy automotive networks, while the 13 hardware 18x18 multipliers accelerate audio sample-rate conversion. The -40C to +100C industrial temperature rating aligns with cabin and under-dash thermal environments, though under-hood applications require the AEC-Q100 grade which the Cyclone II family does not provide.

Low-Cost Digital Signal Processing

With 13 dedicated 18x18 hardware multipliers and up to 250 MHz multiply-accumulate throughput, the EP2C5Q208I8 implements modest DSP functions such as FIR filters, Goertzel DFT detectors, audio equalizers, and vibration analysis pipelines at production cost. The 4,608 logic elements plus 119,808 RAM bits accommodate 32-tap to 64-tap FIRs and small FFT cores, while the 2 PLLs synthesize the required DSP clocks from low-frequency external references. Designers in industrial condition monitoring, audio processing, and instrumentation use this combination as a coprocessor next to a low-cost microcontroller.

What is the EP2C5Q208I8?
The EP2C5Q208I8 is an Intel (formerly Altera) Cyclone II Field-Programmable Gate Array built on a 90 nm CMOS process. It integrates 4,608 logic elements, 119,808 bits of embedded RAM across 26 M4K blocks, 13 hardware 18x18 multipliers, 2 PLLs, and 142 user I/O pins, packaged in a 208-pin PQFP for cost-sensitive digital designs. According to Altera's Cyclone II Device Handbook, the device is supplied from a 1.2V core rail.
How much logic capacity does the EP2C5Q208I8 have?
The EP2C5Q208I8 contains 4,608 logic elements arranged as 312 logic array blocks (LABs). Each LAB includes 16 logic elements, local interconnect, and control signals. This capacity sits at the lower end of the Cyclone II family and is suitable for glue logic, state machines, small DSP pipelines, and modest peripheral controllers rather than large parallel-processing workloads.
What package does the EP2C5Q208I8 use?
The EP2C5Q208I8 uses a 208-pin Plastic Quad Flat Pack (208-PQFP, also labeled 208-BFQFP) with 142 user I/O pins. The PQFP package is a gull-wing leaded surface-mount format that supports conventional reflow soldering and rework, making it easier to prototype on than the BGA-only members of the Cyclone II family.
What is the difference between EP2C5Q208I8 and EP2C5Q208C8?
The EP2C5Q208I8 is graded for an industrial operating temperature range of -40C to +100C, while the EP2C5Q208C8 is the commercial variant rated 0C to +85C. Both share the same die, 208-PQFP package, 4,608 LEs, and pinout, so the C8 variant is a drop-in substitute when the wider industrial range is not required and cost is the priority.
Where can I buy the EP2C5Q208I8 and what is the price?
The EP2C5Q208I8 is available from authorized distributors including DigiKey, Mouser, LCSC, and Heisener, with Octopart aggregating 18 distributors worldwide. As of 2026-09-08, LCSC lists the part from USD 13.33 at quantity 1, with volume discounts typically driving the 100-piece break below USD 11 per unit. Lead time is generally stock-to-2 weeks for distributor inventory.
What is a drop-in replacement for the EP2C5Q208I8?
Drop-in pin-compatible substitutes for the EP2C5Q208I8 in the same 208-PQFP package include EP2C5Q208C8 (commercial temp grade, same die), EP2C5Q208C7N (commercial, faster speed grade 7 with N-lead finish), and EP2C5Q208C7. All share the same 208-PQFP footprint and pinout, so the PCB land pattern does not need modification. Choose the C8 for best cost, I8 for industrial temperature.
Does the EP2C5Q208I8 support DDR SDRAM interfaces?
Yes. The Cyclone II family includes dedicated DDR SDRAM interface logic that supports DDR1 and DDR2 memory through the FPGA's I/O elements and DLLs. Combined with the device's 4 clock networks and 2 PLLs, the EP2C5Q208I8 can implement a DDR memory controller in user logic at speeds up to 167 MHz, sufficient for buffered video frame stores and bulk data buffers.
Which I/O standards does the EP2C5Q208I8 support?
According to the Cyclone II Device Handbook, the EP2C5Q208I8 supports LVTTL, LVCMOS, PCI, SSTL-2, SSTL-3, LVDS, RSDS, mini-LVDS, and PPDS I/O standards. The 208-PQFP package provides 142 user I/O pins organized into 4 I/O banks, each with its own VCCIO supply so different I/O voltage domains can coexist on the same device.
What software is required to program the EP2C5Q208I8?
The EP2C5Q208I8 is supported by Altera Quartus II Web Edition and the legacy branch of Quartus Prime (13.0sp1 with Cyclone II device support). Designers write HDL in Verilog or VHDL, perform synthesis, place-and-route, timing analysis, and programming file generation in Quartus, then configure the device via JTAG, passive serial, or Altera EPCS serial configuration EEPROMs.
How many PLLs and clock networks does the EP2C5Q208I8 have?
The EP2C5Q208I8 includes 2 general-purpose PLLs and 4 global clock networks. The PLLs provide clock multiplication, division, phase shifting, and frequency synthesis, while the 4 global clock networks distribute low-skew clocks across the device to drive logic array blocks, M4K RAM blocks, and multiplier blocks. This is sufficient for most medium-complexity multi-clock designs.
Is the EP2C5Q208I8 still in production?
According to Altera/Intel Cyclone II product status information, the EP2C5Q208I8 remains classified as active, with the Cyclone II family still receiving long-term support via the legacy Quartus branch. New designs are, however, increasingly migrating to Cyclone IV or Cyclone V equivalents due to the Cyclone II family's older 90 nm process and Quartus version constraints.
What is the maximum operating frequency of the EP2C5Q208I8?
The Cyclone II family datasheet references an internal maximum toggle frequency in the 402 MHz range for the FPGA logic fabric, but actual achievable performance depends on the user design, routing, and timing closure in Quartus. According to FindIC summary specifications, the EP2C5Q208I8 is rated at approximately 402.58 MHz maximum internal frequency, sufficient for typical glue logic and DSP pipelines.
Where can I download the EP2C5Q208I8 datasheet PDF?
The official Altera Cyclone II Device Handbook (document CII51008) is the authoritative reference for the EP2C5Q208I8 and is available at https://www.altera.com/literature/hb/cyc2/cyc2_cii51008.pdf. For pinout-specific information, refer to the Cyclone II Pin Information file (CII51012). Both documents are hosted on the legacy Altera section of Intel's website and are mirrored on datasheet distribution sites.
What is the difference between Cyclone II and Cyclone IV FPGAs?
Cyclone IV is the successor family to Cyclone II, manufactured on a 60 nm low-power process with integrated transceivers and hard PCIe blocks in the GX variant. Cyclone II is 90 nm without transceivers and without hard PCIe, but remains lower cost for purely digital logic designs. The EP2C5Q208I8 in 208-PQFP has no direct Cyclone IV replacement in PQFP - Cyclone IV uses BGA packages - so for PQFP continuity, the EP2C5 is still recommended.

選定ガイド

Choose the EP2C5Q208I8 when you need a low-cost Cyclone II FPGA with industrial temperature grade (-40C to +100C) in a hand-solderable 208-PQFP package for prototypes, low-volume production, or field-deployed industrial equipment. Choose EP2C5Q208C8 if you only need commercial 0C to +85C range and want the lowest unit cost - it is the same die in the same PQFP package. Choose EP2C5Q208C7/C7N when timing closure demands a faster speed grade. Switch to the EP2C5F256I8N only when you need higher I/O count (158 vs 142 pins) and can absorb the BGA package's rework complexity. For new designs without a Cyclone II legacy requirement, consider migrating to Cyclone IV or Cyclone V - they offer lower power and hard IP blocks, but lose the 208-PQFP package option.

設計ノート

The Cyclone II EP2C5Q208I8 requires a clean 1.2V core supply plus per-bank VCCIO rails (typically 1.8V, 2.5V, or 3.3V depending on the I/O standard). Decouple each VCC pin with a 0.1 uF X7R ceramic placed within 100 mils of the pin, and add bulk 33 uF to 100 uF tantalum or polymer capacitors near the FPGA. Estimated: based on Altera Cyclone II power estimator, an EP2C5Q208I8 design at 50% utilization and 100 MHz typical clock draws approximately 200-400 mA from VCCINT (1.2V). Always validate with the Quartus PowerPlay early-estimation tool against your real RTL.

For high-speed LVDS or DDR interfaces on the 208-PQFP package, match trace lengths within +/- 20 mil and use 100 ohm differential impedance. The PQFP lead inductance (typically 5-8 nH per pin) is higher than BGA packages, so high-speed signals above 640 Mbps may require external source-termination resistors near the FPGA pin. Provide at least 4 GND and 4 VCC pins distributed around the package to minimize loop inductance for the core supply.

Do not confuse the I8 temperature grade letter with a speed grade - I8 means Industrial temp (-40C to +100C) with speed grade 8, while C8 means Commercial temp (0C to +85C) with speed grade 8. Lower speed-grade numbers (e.g., 7 or 6) are faster but not always cheaper; verify your timing constraints before swapping. Also note that Cyclone II is supported by Quartus II 13.0sp1 and earlier, but not by current Quartus Prime releases - download the legacy toolchain before starting RTL development.
