EP20K30ETC144-2X Tóm tắt

The Intel (Altera) EP20K30ETC144-2X is a member of the APEX 20KE family of Field Programmable Gate Arrays (FPGAs) that integrates 192 macrocells, 30,000 typical gates, and 1,200 logic elements in a 144-pin LQFP (E-type temperature, -2 speed grade) surface-mount package.

An FPGA (Field-Programmable Gate Array) is a reprogrammable semiconductor device containing an array of configurable logic blocks (CLBs), programmable interconnects, and I/O cells, allowing engineers to implement custom digital circuits without the cost or lead time of an ASIC. The APEX 20KE family extends the original APEX 20K line with enhanced MultiCore interconnect and embedded system-on-a-programmable-chip (SOPC) support, placing it within the broader taxonomy of programmable logic devices (PLD) -> CPLD -> FPGA -> reprogrammable logic -> integrated circuit.

Key features of the EP20K30ETC144-2X include 24,576 typical logic elements / system gates, 1,200 logic cells, 92 user I/O pins, internal frequency support up to 160 MHz, and a propagation delay of approximately 1.68 ns. The device operates from a 1.8 V core supply and supports multiple I/O standards via dedicated I/O banks. Its MultiCore architecture combines Look-Up Table (LUT)-based logic with embedded array blocks (EABs) for memory and arithmetic functions.

The MultiCore architecture allows designers to allocate silicon resources between fine-grained LUT logic and coarse-grained EAB memory blocks, optimizing the device for DSP, datapath, or control-plane applications. Each EAB can be configured as RAM, ROM, or multiplier, giving the APEX 20KE flexibility that pure LUT-only FPGAs of the era lack. The 1.8 V core and 1.5 V internal supply rails are generated on-chip from the external VCCINT pin, simplifying power-tree design.

Typical applications include telecommunications line cards, industrial control and glue logic, PCI bridge interfaces, and legacy system upgrades where pin-compatible migration to newer FPGA families is not required. The 144-pin LQFP package is footprint-friendly for through-hole-replacement designs and breadboard-friendly prototypes. The device is suitable for both volume production and end-of-life replacement scenarios, given its mature APEX 20KE tool chain (Quartus II versions prior to 13.0).

When designing with the EP20K30ETC144-2X, ensure your Quartus II tool chain version supports the APEX 20KE device family and that the JTAG chain matches the 10-pin Altera header pinout. EAB-based memory blocks must be instantiated via MegaWizard Plug-Ins or LPM library calls, and unused I/O pins should be configured as tri-stated inputs with weak pull-ups to minimize in-rush current.
