EP20K1000CB652C8ES

Overview

The Altera EP20K1000CB652C8ES is a high-density Field Programmable Gate Array (FPGA) belonging to the APEX 20KC family. It features a MultiCore architecture integrating look-up table (LUT) logic and embedded system blocks (ESBs). The device provides up to 38,400 logic elements (LEs), 160 ESBs, and a maximum of 327,680 RAM bits. It operates at an internal supply voltage (VCCINT) of 1.8 V with MultiVolt I/O support for 1.8-V, 2.5-V, and 3.3-V interfaces. Manufactured using a 0.15-µm all-layer copper-metal process, it offers enhanced performance over previous generations.

Feature Summary

• MultiCore Architecture: Combines LUT-based logic for register-intensive functions with product-term-based logic and embedded memory.
• High-Density Resources: Includes up to 38,400 LEs, 160 ESBs, and 327,680 RAM bits without reducing available logic.
• Advanced Interconnect: Utilizes four-level hierarchical FastTrack interconnect with dedicated carry and cascade chains for high-speed arithmetic and wide fan-in logic.
• Clock Management: Features up to four phase-locked loops (PLLs) with ClockLock, ClockBoost, and ClockShift capabilities.

Applications

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

Procurement Notes

Verify the specific ordering suffix 'ES' against official documentation, as standard datasheets typically list grades such as -7, -8, or -9. Confirm RoHS compliance status, as earlier APEX 20KC variants may not be fully compliant. Check for End-of-Life (EOL) notifications or Product Change Notifications (PCN) from Altera/Intel, as this series has been superseded by newer architectures.

Selection Notes

Select the EP20K1000CB652C8ES when designs require high pin counts (up to 708 user I/O in BGA packages) and significant embedded memory resources. Ensure the design fits within the 38,400 LE limit and utilizes the 1.8-V core voltage. Consider the 652-pin BGA package constraints and thermal requirements associated with the copper interconnect technology.

Part Context

This component is part of the APEX 20KC series, which succeeded the APEX 20KE devices. It shares pin compatibility with the APEX 20KE family while offering 25% to 35% faster design performance due to the 0.15-µm copper fabrication process. It is designed for System-on-a-Programmable-Chip (SOPC) applications.

Replacement Considerations

For direct pin-compatible upgrades within the same density class, consider the EP20K1000CE series. For modern replacements with similar logic density, evaluate Intel Agilex or Stratix families, though architectural differences require full design re-verification.
