EP20K160ETC144-2N Descripción general

The Intel EP20K160ETC144-2N is a member of the APEX 20KE family of Field Programmable Gate Arrays (FPGAs), delivering 160,000 system gates, 640 logic elements, and 81,920 RAM bits in a 144-pin LQFP package. The device operates from a 1.8V core supply and supports 88 user I/Os with MultiCore architecture combining LUT-based logic and embedded memory blocks. Internal frequency up to 160 MHz makes it suitable for glue logic, bridge, and control-plane designs in legacy industrial and telecom systems.

An FPGA (Field Programmable Gate Array) is a semiconductor device built around an array of configurable logic blocks (CLBs) interconnected by a programmable routing matrix, allowing designers to implement custom digital circuits without the mask and NRE costs of an ASIC. APEX 20KE FPGAs occupy the system-on-a-programmable-chip (SOPC) tier, sitting between simple CPLDs (hundreds of gates) and modern high-end FPGAs (millions of LUTs), and historically targeted DSP, communications, and bus-interface applications.

Key features include embedded system blocks (ESBs) that can be configured as dual-port RAM, ROM, FIFO, or CAM; 4-input look-up tables for combinational logic; and a low-power 0.18-micron CMOS process. The 144-LQFP package (20x20 mm body) provides 88 usable I/O pins, sufficient for parallel buses such as PCI, Utopia, or proprietary memory interfaces.

Architecture details: the MultiCore architecture integrates MegaWizard-style function libraries and supports LVTTL, LVCMOS, PCI, and SSTL I/O standards via programmable drive strength and slew rate. The 640 logic elements and 16 ESBs deliver roughly 51,000 typical gates after synthesis, and JTAG (IEEE 1149.1) plus passive serial configuration is supported.

Typical applications include PCI bus interfaces, telecommunications glue logic, legacy industrial controllers, and DSP preprocessing blocks. This part remains in use where long-life-cycle, mature silicon is required.

Design consideration: confirm Quartus II support for this older APEX 20KE device and budget for 1.8V core plus 3.3V I/O supply rails. Migration to Cyclone IV or MAX 10 should be evaluated for new designs.

This page synthesizes distributor stock, drop-in same-family alternatives, and engineering notes not found in the legacy datasheet, providing purchasing and second-source guidance for long-lifecycle designs.

Guía de selección

Choose EP20K160ETC144-2N when you need the highest density APEX 20KE FPGA in a 144-LQFP package for new or legacy designs requiring up to 160K system gates, 640 logic elements, and 88 user I/Os at 1.8V core with commercial temperature operation. Select EP20K160ETC144-2 (no N suffix) for equivalent functionality with slightly different temperature screening. Select EP20K100ETC144-2N for cost-sensitive designs where 100K gates (vs 160K) is sufficient and pin-compatible drop-in replacement is needed. Choose EP20K160ETC144-2X for industrial temperature applications requiring -40 C to 100 C operation. For completely new designs, consider migrating to Cyclone IV or MAX 10 families, as the APEX 20KE family is approaching end-of-life.

Notas de diseño

Estimated: at 100% toggle rate on all 88 I/Os with 50 pF output capacitance, core current reaches approximately 200 mA plus 50 mA I/O. Provide at least 0.1 uF ceramic decoupling on every VCCINT and VCCIO pin, plus bulk 47 uF tantalum on each rail. Sequence 1.8V core before 3.3V I/O to prevent I/O driving into unpowered inputs and latch-up risk.

The 144-LQFP package has a theta_JA of approximately 32 C/W in still air. Estimated at full-load core current 200 mA at 1.8V, dissipation is 0.36 W, yielding a 12 C rise above ambient. In enclosed industrial enclosures with no airflow, derate to 50 mA core current or attach a small clip-on heatsink if the part operates at extended ambient above 70 C.

Do not exceed VCCINT absolute maximum of 2.0V or VCCIO absolute maximum of 4.6V. The nSTATUS and CONF_DONE lines are open-drain and require 10 kohm pull-ups to VCCIO. When using passive serial configuration, MSEL pins must be tied to GND via 1 kohm resistors, not left floating. JTAG TCK must be pulled low during power-up to prevent spurious configuration. Older Quartus II versions (13.0 and earlier) are recommended for APEX 20KE synthesis as newer Quartus versions do not support this legacy family.
