EP20K100EQC208-2X

Overview

The Altera EP20K100EQC208-2X is a programmable logic device from the APEX 20KE family, utilizing MultiCore architecture. It features 4,160 logic elements (LEs), 26 embedded system blocks (ESBs), and up to 53,248 RAM bits. The device operates at a 2.5 V internal supply voltage with MultiVolt I/O support for 1.8 V, 2.5 V, 3.3 V, and 5.0 V levels. Packaged in a 208-pin QFP, it supports high-speed interfaces including PCI Local Bus Revision 2.2 and LVDS. The -2 speed grade ensures compliance with 32/64-bit, 33-MHz PCI specifications.

Feature Summary

• MultiCore architecture integrating LUT logic, product-term logic, and embedded memory
• 2.5 V internal supply with MultiVolt I/O interface supporting multiple voltage levels
• Four-level hierarchical FastTrack Interconnect with dedicated carry and cascade chains
• Flexible clock management with up to four PLLs and ClockLock feature

Applications

• System-on-a-programmable-chip integration
• PCI Local Bus compliant designs
• High-speed digital signal processing applications
• Complex state machine implementations

Procurement Notes

Verify the specific -2X suffix against official documentation to confirm exact timing characteristics and package variations. As an older generation component, availability may be limited; check for end-of-life status or alternative sourcing channels. Ensure compatibility with legacy configuration devices such as EPC1 or EPC2 for serial programming requirements.

Selection Notes

Select this model when design requirements exceed standard CPLD capabilities but do not necessitate modern FPGA densities. The EP20K100E offers a balance of logic density and embedded memory suitable for mixed register-intensive and combinatorial tasks. Consider the -2 speed grade if strict 33 MHz PCI timing constraints are required.

Part Context

This component belongs to the APEX 20KE series, which extends the original APEX 20K family with enhanced I/O standards and additional global clocks. The 'E' suffix denotes the extended feature set, while 'QC208' indicates the plastic quad flat pack package with 208 pins. The EP20K100E represents a mid-range capacity within this high-performance PLD lineage.

Replacement Considerations

No direct public substitutes are listed. Legacy replacements may include other APEX 20K variants like the EP20K60E or EP20K160E depending on resource needs. Modern equivalents would require migration to Intel Cyclone or Stratix families, involving significant architectural redesign.
