EPF10K100EQC208-2X Overview

The Altera (Intel) EPF10K100EQC208-2X is a member of the FLEX 10KE family of Field Programmable Gate Array (FPGA) ICs, delivering 100,000 system gates with 4,992 logic elements/cells and 49,152 bits of embedded memory in a 208-pin Plastic Quad Flat Pack (PQFP / 208-BFQFP) package. Built on a 0.22 µm SRAM-based process, the device operates from a 2.375 V to 2.625 V core supply (2.5 V nominal), supports 147 user I/O pins, and is offered in the commercial -2 speed grade with a guaranteed internal operating frequency of up to 250 MHz.

An FPGA (Field Programmable Gate Array) is a programmable logic device that allows engineers to implement custom digital circuits after PCB fabrication, sitting in the broader hierarchy of programmable logic -> programmable logic devices -> digital ICs -> semiconductors. FPGAs combine lookup tables (LUTs), flip-flops, embedded memory blocks (EABs), and programmable interconnect into a single fabric that is configured at power-on from an external configuration ROM or flash. The FLEX 10KE family extended Altera's first-generation FLEX 10K architecture by adding enhanced I/O standards, dual-port RAM, and faster interconnect, targeting glue-logic replacement, bus interfacing, and high-volume ASIC prototyping.

Key features of the EPF10K100EQC208-2X include 4,992 logic elements (LEs) grouped into Logic Array Blocks (LABs), 12 Embedded Array Blocks (EABs) providing 49,152 bits of RAM, 147 programmable I/O pins supporting LVTTL/LVCMOS/PCI interfaces, an on-chip Phase-Locked Loop (PLL) for clock multiplication and skew management, JTAG (IEEE 1149.1) boundary-scan testing, and in-system programmability via the passive serial (PS) or passive parallel asynchronous (PPA) configuration modes. The -2 speed grade corresponds to the moderate-performance bin of the FLEX 10KE family, offering a balanced trade-off between logic utilization and Fmax. The 208-pin PQFP package measures 28 mm × 28 mm with a 0.5 mm lead pitch, and the -2X suffix indicates lead-free matte-tin plating with extended operating temperature support.

Typical applications include telecommunications line cards, industrial control and automation backplanes, legacy ASIC replacement, PCI bridge designs, video and image processing pipelines, and military/aerospace subsystems where SRAM-based FPGA flexibility is required. The wide 2.5 V core supply tolerance allows operation from regulated 3.3 V rails with simple LDO regulation. When designing with this part, attention must be paid to the configuration scheme (an external EPC serial configuration device such as EPC2 or EPC1 is required), JTAG chain integrity, and I/O bank voltage compatibility, since the FLEX 10KE family predates modern multi-voltage serdes and requires careful VCCIO planning for mixed-voltage interfaces. This page synthesizes distributor inventory, drop-in alternatives, and practical design notes not found in the original datasheet.
