EP2C8Q208I8N Ringkasan

The Altera (Intel) EP2C8Q208I8N is a Cyclone II family Field-Programmable Gate Array (FPGA) delivering 8,256 logic elements and 165,888 bits of embedded RAM in a 208-pin Plastic Quad Flat Pack (PQFP) package. Built on a 90 nm low-k dielectric process with 1.15 V to 1.25 V core VCC, it targets cost-sensitive digital logic integration, glue logic replacement, and Nios II embedded processor designs.

An FPGA (Field-Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs), programmable interconnect, and I/O cells that the user defines after manufacture via a hardware description language. FPGAs sit hierarchically between fixed-function ASICs and software-driven microcontrollers: they offer ASIC-level deterministic timing and parallelism while remaining reprogrammable like a microcontroller. The Cyclone II family specifically positioned itself as a low-cost, high-volume alternative to ASICs in consumer, industrial, and communications equipment.

Key parametric features of the EP2C8Q208I8N include 138 user I/O pins (up to 182 usable I/Os depending on pin assignment), 18 embedded 18x18 multipliers for DSP, and up to 1.1 Mbit of on-chip memory. The device supports LVDS, LVTTL, LVCMOS, SSTL, and HSTL I/O standards and includes up to four phase-locked loops (PLLs) for clock synthesis and management. Configuration is supported via active serial (AS), passive serial (PS), and JTAG modes, allowing flexible in-system programming.

Architecturally, the EP2C8Q208I8N uses Altera's Logic Array Block (LAB) structure with each LAB containing 16 logic elements, and the interconnect fabric is built from TSMC's 90 nm process to balance cost and performance. This process node delivers sufficient speed for 320 MHz internal operation while keeping die size and unit cost low, which is why Cyclone II dominated cost-optimized FPGA designs throughout the late 2000s and remains a long-life-cycle part in industrial retrofit and legacy systems.

Typical applications include Nios II embedded processor systems, digital signal processing front-ends, industrial control and motor drive glue logic, video processing pipelines, communications protocol bridging, and ASIC prototyping. Engineers typically choose this device when they need moderate logic density and DSP capability without paying for higher-tier FPGAs such as Cyclone IV or Cyclone V families.

When designing with the EP2C8Q208I8N, observe the 1.15 V to 1.25 V core supply tolerance and provide proper decoupling on every VCC pin. The PQFP-208 package exposes a thermal pad that must be soldered to a copper pour for adequate heat dissipation, and the JTAG chain must include proper TMS/TCK pull-ups to ensure reliable configuration.

This page synthesizes distributor pricing, drop-in pin-compatible alternatives, and practical PCB design notes for the EP2C8Q208I8N that are not aggregated in the original Altera Cyclone II Device Handbook, helping engineers evaluate both new designs and long-term supply scenarios.
