EP20K160EQC208-2

Overview

The Altera EP20K160EQC208-2 is a Field Programmable Gate Array (FPGA) belonging to the APEX 20KE device family. It features a MultiCore architecture integrating look-up table (LUT) logic, product-term logic, and embedded system blocks (ESB). The device provides 6,400 logic elements (LEs), 40 ESBs, and supports up to 81,920 RAM bits. It operates at a maximum system frequency of 170 MHz with a 1.8 V internal supply voltage (VCCINT). The component is housed in a 208-pin Plastic Quad Flat Pack (PQFP) package and supports commercial operating temperatures from 0°C to +70°C.

Feature Summary

• MultiCore Architecture: Combines LUT-based logic for register-intensive functions, product-term logic for combinatorial paths, and Embedded System Blocks (ESB) for memory implementation.
• High Density Logic: Contains 6,400 LEs, 640 macrocells, and 40 ESBs capable of implementing FIFO, dual-port RAM, and CAM.
• Advanced I/O Support: Features MultiVolt I/O interface supporting 1.8-V, 2.5-V, 3.3-V, and 5.0-V levels, compliant with PCI Local Bus Specification Revision 2.2.
• Clock Management: Includes four phase-locked loops (PLLs), ClockLock for delay reduction, and ClockBoost for clock multiplication/division.

Applications

• System-on-a-programmable-chip (SOPC) integration designs
• Digital IF processing and signal processing applications
• Complex state machines and control logic requiring high-speed combinatorial paths
• PCI bus interface implementations

Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Verification of authenticity is critical when sourcing from secondary markets due to discontinuation status. Confirm RoHS compliance details and humidity sensitivity handling requirements prior to procurement, as standard packaging may not reflect current manufacturing standards.

Selection Notes

Select this model for designs requiring a balance of register-intensive LUT logic and complex combinatorial product-term structures within a single chip. The 208-pin PQFP package is suitable for applications prioritizing through-hole or standard surface-mount compatibility over higher pin-count BGA options. Ensure the design fits within the 6,400 LE and 81,920-bit memory constraints.

Part Context

The EP20K160EQC208-2 is part of the APEX 20KE series, an evolution of the original APEX 20K family. The 'E' suffix indicates enhanced features such as support for additional I/O standards (LVDS, LVPECL, SSTL) and extended clock management capabilities compared to non-E variants. It sits between the EP20K100E and EP20K200E in terms of logic density within the 208-pin package lineup.

Replacement Considerations

Direct functional replacements are unavailable due to the End-of-Life status. Consider migrating to Intel/Altera Cyclone II, III, or IV families for modern equivalents. Verify pinout compatibility if substituting with other APEX 20K devices like the EP20K160EQC208-3N, noting differences in speed grades and specific I/O standard support.
