EP1C6F256C2 Ringkasan

The Intel (formerly Altera) EP1C6F256C2 is a member of the first-generation Cyclone FPGA family fabricated on a 0.13 µm SRAM process. The device integrates 5,980 logic elements (LEs), 92,160 RAM bits organized as 20 M4K memory blocks, and two phase-locked loops (PLLs) for clock management. It is housed in a 256-ball FineLine BGA package (F256) measuring 17 mm × 17 mm with a 1.0 mm ball pitch, offering high I/O density in a compact surface-mount footprint.

An FPGA (Field-Programmable Gate Array) is a type of programmable logic device (PLD) that contains an array of configurable logic blocks (CLBs), programmable interconnect, and configurable I/O cells, all of which can be reconfigured after manufacture to implement custom digital circuits. Within the broader taxonomy, an FPGA sits alongside CPLDs as a digital logic IC family, above fixed-function ASICs in flexibility, and under the wider semiconductor hierarchy as a member of programmable logic devices (PLDs) > digital ICs > integrated circuits. The Cyclone family specifically targets low-cost, high-volume applications requiring moderate logic density and high I/O count.

Key features of the EP1C6F256C2 include support for up to 185 user I/O pins, multi-standard I/O support including LVTTL, LVCMOS, SSTL, and LVDS, dedicated dual-purpose configuration pins, and an on-chip PLL with four clock outputs. The device supports both passive serial (PS) and JTAG configuration modes via Altera's Quartus II / Quartus Prime design software, and it operates from a 1.5 V core supply with separate VCCIO banks for I/O voltage flexibility (1.5 V, 1.8 V, 2.5 V, or 3.3 V).

The Cyclone architecture is built around four-input look-up tables (4-LUTs) feeding carry chains and register chains, with embedded M4K memory blocks capable of true dual-port operation at 200 MHz. The two PLLs provide clock multiplication, division, phase shifting, and duty-cycle control. Compared with newer Cyclone generations (II, III, IV, V), the original Cyclone offers lower LE count and no dedicated DSP blocks, but it remains widely deployed in cost-sensitive designs such as industrial control, video processing, and bridge applications.

Typical applications for the EP1C6F256C2 include glue logic replacement, custom peripheral interfaces, low-cost video processing pipelines, I/O expansion and bus bridging, and educational / prototyping platforms. It is commonly used as a co-processor in embedded systems where microcontrollers lack sufficient I/O bandwidth or processing parallelism.

When designing with this device, note that the F256 BGA package requires careful PCB layout: a minimum 4-layer stack-up with controlled-impedance traces is recommended, and the 1.0 mm ball pitch demands precise reflow profiling. Unused I/O pins should be left floating or tied to a defined logic level per Quartus pin assignment guidance.

This page synthesizes distributor availability, same-brand drop-in variants (different speed/temperature grades), and practical design guidance not found in the original Cyclone family datasheet, giving procurement and design engineers a single-page decision reference.
