EP1C6T144C7 Ringkasan

The Altera (Intel) EP1C6T144C7 is a Cyclone family Field-Programmable Gate Array (FPGA) integrating 5,980 logic elements, 92,160 RAM bits, and 98 user I/O pins in a 144-pin TQFP/LQFP package. It is fabricated on a 130 nm process, operates from a 1.5 V core supply with 3.3 V I/O tolerance, and supports up to 320 MHz internal operation. The device belongs to the original Cyclone generation that introduced a low-cost FPGA architecture for high-volume applications.

A Field-Programmable Gate Array (FPGA) is a programmable logic device containing an array of configurable logic blocks (CLBs) interconnected via a programmable routing fabric. The Cyclone family sits within Altera's mid-density product hierarchy, between the smaller Cyclone II entry parts and the higher-end Stratix devices. FPGAs enable designers to implement custom digital logic, glue logic, and parallel processing functions that can be reconfigured after PCB assembly, making them distinct from fixed-function ASICs and from CPLDs that target simpler glue-logic tasks.

Key features include 5,980 logic elements distributed across 598 logic array blocks (LABs), 92,160 bits of embedded RAM, two phase-locked loops (PLLs) for clock management, and 98 user I/O pins supporting LVTTL, LVCMOS, SSTL, and differential I/O standards. The device integrates dedicated 18 x 18 hardware multipliers that support DSP functions such as FIR filters and video processing without consuming general-purpose logic.

The Cyclone architecture combines a four-input look-up-table logic element with embedded memory blocks, multiplier blocks, and PLL clock networks. The 130 nm process node balances cost and performance, with the TQFP-144 package providing a low-cost plastic platform suitable for prototype and moderate-volume production where BGA packages would be uneconomical.

Typical applications include industrial control, video processing, consumer electronics, communications glue logic, and educational prototyping boards. The combination of moderate logic capacity, embedded multipliers, and a low-cost TQFP package makes the EP1C6T144C7 particularly suitable for designs transitioning from discrete logic or CPLD-based implementations.

When designing with this device, ensure the Quartus II design software is used (legacy versions support the original Cyclone family), and verify that the 1.5 V core supply is well-decoupled with bulk and high-frequency ceramic capacitors placed close to the VCCINT pins.
