EP20K200EQI240-2

Overview

The EP20K200EQI240-2 is an APEX 20KE Field Programmable Gate Array manufactured by Altera. It features the MultiCore architecture, integrating look-up table logic, product-term logic, and embedded system blocks (ESB). The device provides 8,320 logic elements, 52 ESBs, and supports up to 106,496 RAM bits. It operates at a maximum system frequency of 170 MHz with a 2.5 V internal supply voltage. The component is housed in a 240-pin QFP package and supports 168 user I/O pins.

Feature Summary

• MultiCore architecture combining LUT-based logic for register-intensive functions and product-term logic for combinatorial paths.
• Embedded System Blocks (ESB) supporting FIFO buffers, dual-port RAM, and content-addressable memory.
• Flexible clock management with four phase-locked loops (PLLs), ClockLock, and ClockBoost features.
• MultiVolt I/O interface supporting 1.8-V, 2.5-V, 3.3-V, and 5.0-V devices.

Applications

• System-on-a-programmable-chip (SOPC) integration
• High-speed data-path and digital signal processing (DSP) designs
• Complex state machines and combinatorial-intensive functions
• PCI Local Bus Specification compliant interfaces

Procurement Notes

Verify the specific suffix 'E' indicates APEX 20KE features, including enhanced I/O standards and additional global clocks compared to standard APEX 20K. Confirm the '-2' speed grade corresponds to the 170 MHz maximum frequency. Check RoHS compliance status as indicated in distributor listings, which may show non-compliance for older manufacturing runs.

Selection Notes

Select this model when design requirements exceed the capacity of smaller APEX 20K devices but do not necessitate the higher density of the EP20K400 series. Ensure the 240-pin QFP package fits the board space constraints, as alternative packages like BGA offer more I/O but different footprints. Verify that the 2.5 V core voltage aligns with the power delivery network design.

Part Context

This part belongs to the APEX 20KE family, which extends the original APEX 20K line with advanced features such as LVDS support and additional PLLs. It represents a high-density solution from Altera's programmable logic portfolio prior to the introduction of Stratix and Cyclone families.

Replacement Considerations

Direct pin-to-pin replacements are not available within the same family due to architectural differences. Consider Intel/Altera Agilex or Stratix families for modern equivalents, though these require significant redesign of logic and physical layout.

FAQ

What is the difference between EP20K200 and EP20K200E?

The EP20K200E is an APEX 20KE device that includes enhanced features such as support for 1.8-V I/O, additional global clocks, ClockLock circuitry, and advanced I/O standards like LVDS and PCI-X, which are not present in the standard EP20K200.

How many Embedded System Blocks (ESBs) does the EP20K200EQI240-2 contain?

The EP20K200EQI240-2 contains 52 Embedded System Blocks (ESBs), which can be configured as RAM, ROM, FIFO, or CAM.

What is the maximum operating frequency for this device?

The maximum system frequency for the -2 speed grade of the EP20K200E is 170 MHz.
