EP2C8T144C6 - Cyclone II FPGA, 8K LE, 144-LQFP | Intel (Altera)
The Intel (Altera) EP2C8T144C6 is a low-cost Cyclone II Field Programmable Gate Array (FPGA) delivering 8,256 logic elements, 165,888 bits of embedded RAM, and 85 user I/O pins in a 144-pin LQFP (TQFP) surface-mount package. Built on a 1.2 V, 90 nm CMOS process and speed-grade -6, the device targets cost-sensitive logic integration, glue logic, and control-plane applications where ASIC-like unit economics and FPGA flexibility are simultaneously required.
A Field Programmable Gate Array (FPGA) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs), programmable interconnect, and dedicated hard-IP blocks such as embedded RAM, PLLs, and (in modern families) transceivers and DSP slices. FPGAs sit in the broader hierarchy of programmable logic devices -> PLD -> semiconductor -> integrated circuit, and they are typically deployed between microcontrollers (for highly parallel or latency-critical workloads) and ASICs (for high-volume fixed-function logic). The Cyclone II family was Altera's first 90 nm low-cost FPGA family, succeeding the original Cyclone series and predating Cyclone III/IV/V.
Key features of the EP2C8T144C6 include 8,256 logic elements arranged in 516 Configurable Logic Blocks (CLBs), 18 embedded 18x18 multipliers that support DSP-style operations up to 250 MHz, and 36 M4K RAM blocks (4,608 bits each) for distributed buffering. The device integrates four general-purpose PLLs for clock generation, de-skew, and frequency synthesis, and exposes up to 85 user I/Os that support LVDS, LVTTL, LVCMOS, SSTL, and other single-ended and differential I/O standards. Configuration is loaded via the dedicated JTAG (IEEE 1149.1) interface or the Altera serial configuration (AS) / passive parallel (PP) modes.
Architecturally, the EP2C8T144C6 uses a Look-Up Table (LUT)-based logic fabric with four-input LUTs feeding a dedicated carry chain for fast arithmetic, complemented by a sea of M4K memory blocks arranged in columns between LAB (Logic Array Block) rows. The hard multipliers are placed adjacent to LAB rows to support DSP-style MAC operations without consuming general fabric, which historically made Cyclone II popular for video, motor-control, and low-cost signal-processing designs.
Typical applications include industrial motor-control and PLC logic, video-processing front-ends (deinterlacing, scaling, format conversion), low-cost DSP pipelines, embedded control planes for printers/scanners/medical instruments, glue logic replacement around microprocessors and ASICs, and educational/hobbyist platforms where 144-LQFP is hand-solderable. The 144-pin LQFP package has 0.5 mm pitch and 22 mm x 22 mm body, making it compatible with conventional SMT assembly lines.
When designing with this device, pay attention to I/O bank voltage grouping, pin assignment for JTAG (TCK, TMS, TDI, TDO), and configuration scheme selection. Use the Quartus II design software (last released for Cyclone II around v13.0) for synthesis, place-and-route, and timing closure; later Quartus versions drop Cyclone II support. Plan for 1.2 V core, 2.5 V/3.3 V I/O bank supplies, and adequate decoupling close to each supply pin.
This page synthesizes distributor pricing, drop-in same-family alternatives, and practical design notes not found in the manufacturer datasheet alone, helping engineers quickly evaluate the EP2C8T144C6 for both new designs and legacy board re-spins.
