EP1K50QC208-3 Ringkasan

The Altera EP1K50QC208-3 is a member of the ACEX 1K programmable logic family, integrating 50,000 typical gates, 2,880 logic cells, and 40,960 RAM bits into a single 208-pin PQFP package. It is a 2.5 V SRAM-based field-programmable gate array (FPGA) built on a 0.22 µm CMOS process, offering a maximum internal operating frequency of 166.67 MHz with a -3 speed grade. According to the Altera ACEX 1K datasheet family data sheet, the device provides 360 Logic Array Blocks (LABs), 147 user I/O pins, and 12 Embedded Array Blocks (EABs) for dual-port memory and megafunction implementation.

A Field Programmable Gate Array (FPGA) is a programmable logic device (PLD) that combines configurable logic blocks, programmable interconnects, and dedicated memory resources on a single die. Within the integrated-circuit taxonomy, an FPGA sits under programmable logic devices, then semiconductor ICs, and finally integrated circuits. FPGAs are used to implement arbitrary digital logic, signal-processing pipelines, and glue logic that would otherwise require multiple discrete components, while remaining re-programmable in-system to fix bugs or upgrade functionality.

The EP1K50QC208-3's defining features include die-efficient LUT-based logic combined with EAB memory blocks for efficient implementation of RAM, ROM, and specialized megafunctions such as multipliers and FIFO controllers. The device supports in-system configuration via passive serial, active serial, and JTAG modes, and is supported by the Quartus II and MAX+PLUS II design toolchains. The PQFP-208 package supports surface-mount assembly with 147 usable I/Os, sufficient for multi-bus glue-logic and mid-density digital control applications.

The architecture is built around LABs containing 8 Logic Elements (LEs) each, with each LE containing a 4-input LUT, a programmable register, and a carry chain. The EABs provide 4 Kbit memory blocks, configurable as single- or dual-port RAM, ROM, or as look-up-table based logic. The device operates from a 2.5 V core supply with separate VCCIO banks for output voltage flexibility, and exposes multi-voltage I/O standards including LVTTL, LVCMOS, and PCI.

Typical applications include telecommunications line-card glue logic, industrial control systems, test and measurement instrumentation front-ends, and legacy PCI bus interface bridging. The ACEX 1K family was positioned as a low-cost, low-power programmable alternative to ASICs for mid-volume products, and remains in service in long-lifecycle industrial and aerospace programs that have completed extensive design qualification.

When designing with this part, note that the ACEX 1K family has been discontinued by Intel (formerly Altera) and is designated Not Recommended for New Designs. Engineers should validate long-term supply, use authorized-franchise distributors for current production runs, and consider Cyclone II/III/IV or MAX II CPLDs for new designs of similar density.
