EP1C3T100CN8 Ringkasan

The Altera (Intel Programmable Solutions Group) EP1C3T100CN8 is a member of the original Cyclone FPGA family, delivering 2,910 logic elements in a 100-pin TQFP package with up to 65 user I/O pins and 59,904 RAM bits. Operating from a 1.5 V core supply, the device is built on a 0.13 µm SRAM-based FPGA fabric and is offered in a commercial 0 °C to 85 °C temperature grade with -8 speed bin performance.

What is an FPGA? An FPGA (Field-Programmable Gate Array) is a semiconductor device containing programmable logic blocks, configurable interconnect, and programmable I/O cells that engineers can configure after manufacturing to implement custom digital circuits. FPGAs occupy the tier between CPLDs (smaller, non-volatile) and ASICs (custom, high-NRE), making them ideal for prototyping, low-volume production, and applications requiring hardware-level parallelism. The Altera Cyclone family sits in the low-cost, high-volume segment, optimized for price-sensitive designs.

Key features of the EP1C3T100CN8 include two PLLs for clock management, dedicated 18×18 multipliers (originally marketed under the DSP block branding), and support for LVTTL, LVCMOS, SSTL-2, and SSTL-3 I/O standards. The device supports configuration via passive serial (PS), JTAG, and Altera-specific configuration schemes, and integrates Altera's Quartus II design suite for synthesis, place-and-route, and timing closure.

Technically, the Cyclone architecture pairs 4-input look-up-tables (LUTs) with embedded memory blocks (M4K blocks) and distributed multiplier resources. The 100-pin TQFP package provides moderate I/O count with surface-mount manufacturability but limits total pin count compared to BGA-packaged Cyclone variants, so it is typically chosen for I/O-light glue logic, control planes, and industrial interface bridging.

Typical applications include industrial control and bridging, low-cost video processing front-ends, peripheral expansion in embedded systems, glue logic replacing discrete MSI parts, and education/hobby platforms. Designers choose the EP1C3T100CN8 over larger Cyclone devices when logic requirements fit within 3K LEs and the TQFP package simplifies assembly.

Design consideration: this part is NRND/EOL per Intel PSG's Cyclone legacy notice — verify lifetime-buy windows and consider modern Cyclone IV/V/10 equivalents for new designs. Always validate timing closure at the chosen speed grade against target fMAX.

This page synthesizes distributor inventory, drop-in same-package alternatives, and practical design context that goes beyond the manufacturer datasheet front matter, helping engineers source and apply the EP1C3T100CN8 quickly.
