EP20K1000CB652C9ES

Overview

The Altera EP20K1000CB652C9ES is a high-density programmable logic device from the APEX 20KC family, manufactured using a 0.15-µm all-layer copper-metal process. It features up to 38,400 logic elements (LEs), 160 Embedded System Blocks (ESBs) providing up to 327,680 RAM bits, and four phase-locked loops (PLLs). The device operates at a 1.8-V internal supply voltage with MultiVolt I/O support for 1.8-V, 2.5-V, and 3.3-V interfaces. Packaged in a 652-pin Ball Grid Array (BGA), it supports advanced I/O standards including LVDS, PCI-X, and AGP.

Feature Summary

• MultiCore architecture integrating LUT-based logic and embedded memory for optimized performance in register-intensive and combinatorial designs.
• High-speed copper interconnect structure with FastTrack routing, dedicated carry chains, and cascade chains for arithmetic and wide-fan-in functions.
• Flexible clock management featuring four PLLs, ClockLock, ClockBoost, and ClockShift capabilities for low-skew distribution.
• Comprehensive I/O support including 16 LVDS channels, MultiVolt compatibility, and compliance with PCI Local Bus Specification Revision 2.2.

Applications

• Complex state machines and control logic requiring product-term integration.
• Digital signal processing (DSP) and data-path applications utilizing LUT efficiency.
• Memory-intensive designs implementing FIFO buffers, dual-port RAM, or content-addressable memory (CAM).

Procurement Notes

Verify component authenticity through official Altera documentation channels. Confirm that the specific ordering suffix corresponds to the intended speed grade and package variant. Ensure handling procedures account for moisture sensitivity levels as indicated in the datasheet. Cross-reference the part number with current availability status, as legacy devices may have limited supply chains.

Selection Notes

Select this device for applications requiring high gate density and flexible memory configuration within a single chip. Consider the -9 speed grade for maximum timing performance if system requirements exceed lower grades. Evaluate power consumption constraints given the 1.8-V core voltage and MultiVolt I/O flexibility. Ensure design tools are compatible with the Quartus II development system for optimal place-and-route results.

Part Context

This component belongs to the APEX 20KC series, which offers 25% to 35% faster performance compared to the preceding APEX 20KE family while maintaining pin compatibility. It represents a transition to copper interconnect technology, enhancing speed and reducing power consumption relative to previous generations of Altera high-density PLDs.

Replacement Considerations

APEX 20KE devices are pin-compatible but offer lower performance metrics. For direct architectural upgrades, verify that the target application does not require features exclusive to newer families such as Stratix or Arria. Consult the official migration guidelines for detailed parameter comparisons between device families.
