EP20K100EQC208-1X

Overview

The EP20K100EQC208-1X is an APEX 20KE series Field Programmable Gate Array (FPGA) manufactured by Altera. It features a MultiCore architecture integrating Look-Up Table (LUT) logic, product-term logic, and Embedded System Blocks (ESB). The device provides 4,160 Logic Elements (LEs), 416 macrocells, and 53,248 maximum RAM bits. It operates with a 1.8-V internal supply voltage (VCCINT) and supports MultiVolt I/O levels including 1.8 V, 2.5 V, 3.3 V, and 5.0 V. The component is housed in a 208-pin Plastic Quad Flat Package (PQFP) and supports a maximum system frequency of 170 MHz.

Feature Summary

• MultiCore Architecture: Combines LUT-based logic for register-intensive functions, product-term logic for combinatorial paths, and ESBs for memory implementation.
• Embedded Memory: Includes up to 53,248 RAM bits supporting FIFO, dual-port RAM, and CAM functions within the ESBs.
• Clock Management: Features four Phase-Locked Loops (PLLs), ClockLock for delay reduction, and ClockBoost for multiplication/division.
• I/O Flexibility: Supports MultiVolt I/O standards (LVCMOS, LVTTL, PCI, LVDS, etc.) with individual tri-state control and slew-rate adjustment.

Applications

• System-on-a-programmable-chip (SOPC) integration designs
• High-speed interface implementations requiring PCI or LVDS compliance
• Complex state machines and combinatorial-intensive logic applications
• Digital signal processing (DSP) and arithmetic function acceleration

Procurement Notes

Verify the specific suffix 'X' against official manufacturer documentation, as standard datasheets typically list 'EP20K100EQC208-1'. Confirm RoHS compliance status and lead times with authorized distributors, as this device family may be subject to end-of-life notices or discontinuation. Ensure the package type matches the 208-PQFP specification.

Selection Notes

Select this device for applications requiring high-density logic (4,160 LEs) combined with significant embedded memory resources. The 1.8-V core voltage offers lower power consumption compared to 2.5-V variants. Ensure the design utilizes the 208-pin PQFP package constraints and verifies that the required I/O standards are supported by the MultiVolt interface capabilities of the APEX 20KE family.

Part Context

The EP20K100E belongs to the APEX 20KE family, which extends the original APEX 20K line with enhanced features such as 1.8-V operation, additional global clocks, and support for advanced I/O standards like LVDS and PCI-X. This family represents Altera's high-performance programmable logic solutions prior to the introduction of Stratix and Cyclone families.

Replacement Considerations

Direct pin-to-pin replacements are not explicitly listed in public documentation for the 'X' suffix variant. Consider Intel/Altera successor families such as Stratix or Arria for modern equivalents, though these require redesign due to architectural differences and package variations.
