EP20K1000CB652C9N

Overview

The Altera EP20K1000CB652C9N is a 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 38,400 Logic Elements (LEs), 160 ESBs, and up to 327,680 RAM bits. It operates at a 1.8 V internal supply voltage and supports MultiVolt I/O levels of 1.8 V, 2.5 V, and 3.3 V. Manufactured using a 0.15-µm copper process, it utilizes a 652-pin Ball Grid Array (BGA) package with a 1.27 mm pitch.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term logic for combinatorial paths.
• Embedded System Blocks (ESBs) supporting FIFO buffers, dual-port RAM, and Content-Addressable Memory (CAM).
• Advanced clock management with four Phase-Locked Loops (PLLs) and ClockLock circuitry for low-skew distribution.
• Support for high-speed I/O standards including LVDS, PCI-X, AGP, SSTL-3, and HSTL Class I.

Applications

• High-performance digital signal processing (DSP) designs requiring complex arithmetic operations.
• System-on-a-programmable-chip (SOPC) integration combining logic, memory, and interface controllers.
• Complex state machine implementations utilizing product-term-based logic.
• PCI Local Bus Specification compliant interfaces operating at 33 or 66 MHz.

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status as historical data indicates non-compliance for some variants in this series. Ensure handling procedures account for moisture sensitivity classification during storage and reflow soldering processes.

Selection Notes

Select this model for designs requiring high gate density within the APEX 20KC family. The -9 speed grade offers specific timing characteristics suitable for moderate-frequency applications compared to the faster -7 grade. Ensure the design fits within the 38,400 LE limit and verify that the 652-pin BGA package footprint matches the PCB layout constraints.

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 improved performance due to the 0.15-µm copper fabrication process. The EP20K1000C variant represents the highest density option in the standard APEX 20KC lineup.

Replacement Considerations

Pin-compatible alternatives include other members of the APEX 20KC family such as EP20K600C or EP20K400C, though they offer lower logic densities. Direct functional replacements may require migration to newer Intel FPGA families like Arria or Stratix, necessitating significant design adaptation.
