EP20K100EQC240-1

Overview

The Altera EP20K100EQC240-1 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20KE family. It features a MultiCore architecture integrating look-up table (LUT) logic, product-term logic, and embedded memory. The device provides 4,160 logic elements (LEs), 26 Embedded System Blocks (ESBs), and up to 53,248 maximum RAM bits. It supports a 2.5-V internal supply voltage with MultiVolt I/O interface capabilities for 2.5-V, 3.3-V, and 5.0-V levels. The component is housed in a 240-pin Plastic Quad Flat Package (PQFP) and operates within a commercial temperature range of 0°C to +70°C.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term logic for combinatorial-intensive tasks.
• Embedded System Blocks (ESBs) supporting FIFO buffers, dual-port RAM, and content-addressable memory (CAM).
• Flexible clock management with up to four phase-locked loops (PLLs) and ClockLock/ClockBoost features.
• MultiVolt I/O interface supporting 1.8-V, 2.5-V, 3.3-V, and 5.0-V standards including PCI-X and LVDS.

Applications

• System-on-a-programmable-chip (SOPC) integration requiring mixed logic and memory resources.
• High-speed data-path and digital signal processing (DSP) designs utilizing LUT efficiency.
• Complex state machine implementations optimized by product-term-based logic.
• PCI Local Bus Specification compliant interfaces operating at 33 or 66 MHz.

Procurement Notes

Verify the specific -1 speed grade designation against current manufacturer documentation, as availability may be limited due to the age of the APEX 20K family. Confirm package integrity for the 240-pin PQFP form factor. Ensure design tools are compatible with legacy Quartus II versions required for this device generation.

Selection Notes

Select the EP20K100E variant when 2.5-V operation is required, distinguishing it from the standard EP20K100 which uses 1.8-V. Evaluate the 246 user I/O pin count available in the QC240 package against system interface requirements. Consider the 53,248-bit RAM capacity for memory-intensive applications before choosing higher-density models like the EP20K160E.

Part Context

This component is part of the APEX 20KE series, an enhancement over the original APEX 20K line. The 'E' suffix indicates support for advanced I/O standards such as LVDS and PCI-X, along with additional global clock signals. It represents a transition point in Altera's programmable logic portfolio prior to the introduction of Stratix and Cyclone families.

Replacement Considerations

No direct public substitute part numbers are confirmed in the provided source material. Legacy replacements typically require migration to newer Intel/Altera FPGA families with equivalent logic density and I/O counts, necessitating design re-verification.
