EP20K1000CB652C8

Overview

The Altera EP20K1000CB652C8 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 at an internal supply voltage of 1.8 V. The device features a MultiCore architecture integrating look-up table (LUT) logic and embedded memory, providing up to 38,400 logic elements (LEs), 160 Embedded System Blocks (ESBs), and a maximum of 327,680 RAM bits. It supports MultiVolt I/O for 1.8-V, 2.5-V, and 3.3-V interfaces and includes four phase-locked loops (PLLs). The component is housed in a 652-pin Ball Grid Array (BGA) package with a 1.27-mm pitch.

Feature Summary

• Manufactured using a 0.15-µm all-layer copper-metal process for high performance and low power consumption.
• MultiCore architecture combining LUT-based logic and product-term-based logic with Embedded System Blocks (ESBs).
• High-density capacity with 38,400 LEs, 160 ESBs, and up to 327,680 RAM bits.
• Supports MultiVolt I/O standards including 1.8-V, 2.5-V, 3.3-V, and 5.0-V tolerant interfaces.

Applications

• System-on-a-programmable-chip (SOPC) designs requiring integration of logic, memory, and I/O.
• Complex state machines and register-intensive digital signal processing (DSP) functions.
• Memory implementations such as FIFO buffers, dual-port RAM, and content-addressable memory (CAM).

Procurement Notes

Verify the specific speed grade suffix (e.g., -7, -8, -9) required for timing constraints, as the base model number does not specify it. Confirm RoHS compliance status, as historical production runs may vary. Check for End-of-Life (EOL) notifications or Product Change Notifications (PCN) from Altera/Intel, as this component belongs to a legacy FPGA family.

Selection Notes

Select based on logic element count (38,400 LEs) and embedded memory requirements (up to 327,680 bits). Ensure the design fits within the 652-pin BGA package constraints. Verify that the 1.8-V core voltage and MultiVolt I/O capabilities align with the system's power and interface specifications. Consider the -7 speed grade if maximum performance is required.

Part Context

This device is part of the APEX 20KC series, which succeeded the APEX 20KE family. It offers pin compatibility with APEX 20KE devices while providing 25% to 35% faster design performance due to the copper interconnect technology. The EP20K1000C variant represents the highest density option in the standard BGA package lineup for this generation.

Replacement Considerations

Publicly confirmed direct substitute part numbers are not available in the provided documentation. Designers migrating from APEX 20KE should verify pin compatibility. For modern replacements, consult Intel's current FPGA portfolios such as Cyclone or Stratix families, noting architectural differences.
