EP20K400CB652I8ES

Field Programmable Gate Array Overview

The Altera EP20K400CB652I8ES is a Field Programmable Gate Array (FPGA) belonging to the APEX 20KC family. It utilizes a 0.15-µm all-layer copper-metal fabrication process and operates with an internal supply voltage of 1.8 V. The device features a MultiCore architecture integrating look-up table (LUT) logic and embedded system blocks (ESBs). Key specifications include 16,640 logic elements (LEs), 104 ESBs, and a maximum RAM capacity of 212,992 bits. It supports up to 488 user I/O pins and includes four phase-locked loops (PLLs). The component is housed in a 652-pin Ball Grid Array (BGA) package.

Field Programmable Gate Array Feature Summary

• Manufactured using a 0.15-µm all-layer copper-metal process for high-performance interconnect.
• MultiCore architecture combining LUT-based logic for register-intensive functions with product-term logic for complex combinatorial paths.
• Embedded System Blocks (ESBs) support memory functions including FIFO buffers, dual-port RAM, and content-addressable memory (CAM).
• Flexible clock management with up to four PLLs, ClockLock, ClockBoost, and ClockShift features.

Field Programmable Gate Array Applications

• High-density system-on-a-programmable-chip (SOPC) designs requiring integration of logic, control, and memory.
• Complex state machines and digital signal processing (DSP) applications utilizing LUT efficiency.
• Interfaces compliant with PCI Local Bus Specification Revision 2.2 at 33 or 66 MHz.
• Systems requiring hot-socketing capabilities and reconfigurable computing during operation.

Field Programmable Gate Array Procurement Notes

Verify the specific ordering suffix against official documentation, as suffixes may indicate variations in speed grade, temperature range, or packaging. Confirm current availability status, as older FPGA families may have limited stock or discontinuation notices. Ensure compatibility with legacy design tools such as Quartus II if migrating existing projects.

Field Programmable Gate Array Selection Notes

Select this device when pin-compatibility with APEX 20KE devices is required but higher performance is needed. The -8 speed grade offers a balance between speed and power consumption compared to the -7 grade. Consider the 1.8 V core voltage requirement and ensure the board design supports MultiVolt I/O levels (1.8 V, 2.5 V, or 3.3 V) for interface flexibility.

Field Programmable Gate Array Part Context

The EP20K400CB652I8ES is part of the APEX 20KC family, which succeeded the APEX 20KE series. This generation introduced all-copper interconnect technology, providing approximately 25% to 35% faster design performance than its predecessor while maintaining pin compatibility. It represents a transition point in Altera's programmable logic portfolio towards advanced copper processes.

Field Programmable Gate Array Replacement Considerations

Direct pin-compatible replacements within the same family include other APEX 20KC variants such as EP20K200C or EP20K600C, depending on resource requirements. For upgrades, later generations like Stratix or Cyclone families offer increased density but require schematic and layout modifications due to non-pin-compatible interfaces and different voltage domains.
