EP20K100ETC144-1

Overview

The Altera EP20K100ETC144-1N is an APEX 20KE Field Programmable Gate Array (FPGA) housed in a 144-pin Thin Quad Flat Package (TQFP). It operates at a fixed internal supply voltage of 2.5 V and supports MultiVolt I/O levels including 2.5 V, 3.3 V, and 5.0 V. The device provides 4,160 logic elements, 416 macrocells, and 53,248 bits of embedded memory via Embedded System Blocks (ESBs). It features four phase-locked loops for clock management and supports a maximum system frequency of 180 MHz within the commercial temperature range of 0°C to +70°C.

Feature Summary

• MultiCore architecture integrating LUT-based logic, product-term-based macrocells, and Embedded System Blocks (ESBs) for flexible design implementation.
• Supports advanced I/O standards including PCI-X, LVDS, SSTL-3, and HSTL Class I through MultiVolt interface capabilities.
• Includes four Phase-Locked Loops (PLLs) with ClockLock and ClockShift features for precise clock distribution and skew reduction.
• Features FastTrack Interconnect with dedicated carry and cascade chains for high-speed arithmetic and wide-fan-in logic functions.

Applications

• Implementation of feed-forward neural networks for pattern recognition systems.
• Complex state machine designs requiring combinatorial-intensive logic paths.
• System-on-a-programmable-chip (SOPC) integration combining logic, memory, and control functions.

Procurement Notes

This component is listed as End-of-Life (EOL) by the manufacturer. Verification of authenticity is critical when sourcing from third-party distributors due to potential obsolescence. Buyers must confirm RoHS compliance status and moisture sensitivity level handling requirements prior to procurement.

Selection Notes

Select this device for designs requiring a hybrid of register-intensive LUT logic and complex combinatorial product-term structures. Ensure the 2.5 V core voltage aligns with the power budget. Verify that the 144-pin TQFP package meets board space constraints compared to BGA alternatives in the same family.

Part Context

The EP20K100ETC144-1N belongs to the APEX 20KE series, which extends the original APEX 20K family with enhanced I/O standards and additional global clocks. It shares architectural similarities with the EP20K100QC208-1 but differs in pin count and package type. The 'E' suffix denotes support for 5.0-V tolerant I/O using external resistors.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided documentation. Legacy replacements may require redesigning the PCB footprint and updating configuration software due to architectural differences in newer FPGA families.
