EP20K100QC208-2

Overview

The EP20K100QC208-2 is a programmable logic device from the Altera APEX 20KE family, manufactured using a 0.15-µm copper-metal process. It features a MultiCore architecture integrating look-up table (LUT) logic and embedded memory blocks. The device provides up to 6,400 logic elements and supports high-performance applications with speeds up to 35% faster than the preceding APEX 20K series. It operates at a supply voltage of 2.5 V and is housed in a 208-pin QFP package suitable for surface-mount installation.

Feature Summary

• MultiCore architecture combining LUT logic for register-intensive functions and Embedded System Blocks (ESBs) for memory implementations such as FIFOs and dual-port RAM.
• High-density design offering up to 6,400 logic elements within a compact form factor.
• Manufactured on a 0.15-µm all-layer copper-metal fabrication process for enhanced performance and lower power consumption.
• Pin-compatible with the legacy APEX 20K family, facilitating straightforward migration for existing designs.

Applications

• Complex digital signal processing requiring embedded memory buffers.
• High-speed interface bridging and protocol conversion.
• System integration replacing complex discrete logic or PAL/GAL devices.
• Custom ASIC prototyping and verification.

Procurement Notes

This component belongs to an older product generation and may be subject to end-of-life status or limited availability through primary channels. Verification of current stock levels and lead times is necessary before procurement planning. Ensure that the specific suffix matches the required temperature grade and package variant, as these parameters define the electrical characteristics and physical compatibility.

Selection Notes

Select this device when migrating from the APEX 20K family to benefit from improved speed and density without changing pin assignments. The 208-pin QFP package limits I/O count compared to BGA options; verify that 136 available I/O lines meet system requirements. The 2.5V core voltage requires appropriate level shifting if interfacing with 3.3V peripherals. Confirm that the design fits within the 6,400 LE capacity and available embedded memory resources.

Part Context

The EP20K100QC208-2 is part of the APEX 20KE series, which succeeded the original APEX 20K line. This series was designed to offer higher performance and density while maintaining backward compatibility. The 'EP' prefix denotes the EPLD/FPGA category, '20K' indicates the family, '100' refers to the gate count class, 'Q' signifies the QFP package, '208' is the pin count, and '-2' typically indicates the speed grade.

Replacement Considerations

Direct pin-compatible replacements are limited due to the age of the technology. Consider Intel/Altera Cyclone or Stratix families for modern equivalents, though these require significant schematic and layout redesigns. For simple logic replacement, check availability of obsolete APEX 20K stock or generic CPLDs if the logic density allows.
