EP20K1000CB652C7ES

Overview

The EP20K1000CB652C7ES is an APEX 20KC programmable logic device manufactured by Altera using a 0.15-µm copper-metal process. It features the MultiCore architecture, integrating look-up table (LUT) logic and embedded system blocks (ESBs). The device provides up to 38,400 logic elements, 160 ESBs, and a maximum of 327,680 RAM bits. It operates with a 1.8-V internal supply voltage and supports MultiVolt I/O levels of 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The component is housed in a 652-pin ball-grid array package.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term-based logic for complex combinatorial paths.
• Embedded System Blocks (ESBs) supporting FIFO buffers, dual-port RAM, content-addressable memory (CAM), and ROM.
• Flexible clock management with four phase-locked loops (PLLs), ClockLock, ClockBoost, and ClockShift features.
• Support for high-speed interfaces including LVDS, PCI-X, AGP, and DDR SDRAM.

Applications

• System-on-a-programmable-chip (SOPC) designs requiring integration of logic, memory, and processor interfaces.
• High-performance digital signal processing (DSP) and arithmetic applications utilizing dedicated carry chains.
• Complex state machine implementations optimized by product-term-based logic structures.
• Reconfigurable computing systems leveraging real-time in-system reconfiguration capabilities.

Procurement Notes

Verify the specific suffix 'ES' against official documentation, as standard datasheets typically list '-7', '-8', or '-9' speed grades without this designation. Confirm RoHS compliance status and lead times directly with authorized distributors or Altera representatives, as availability may vary for legacy components.

Selection Notes

Select this device for high-density applications requiring up to 38,400 logic elements and extensive embedded memory resources. Ensure design compatibility with the 652-pin BGA package dimensions and pitch. Verify that the target application utilizes the 1.8-V core voltage and compatible MultiVolt I/O standards supported by the APEX 20KC family.

Part Context

This component belongs to the APEX 20KC family, which offers 25% to 35% faster performance than the preceding APEX 20KE series while maintaining pin compatibility. It represents a high-end solution within the Altera CPLD portfolio, designed for complex system integration before the widespread adoption of FPGA architectures.

Replacement Considerations

Direct pin-compatible replacements include other APEX 20KC devices such as EP20K600C or EP20K400C with adjusted capacity. For higher performance requirements, consider migrating to newer Altera families like Stratix or Cyclone, though these will require schematic and layout redesigns due to architectural differences.
