EP20K100CQ208C9 Overview

The Intel (formerly Altera) EP20K100CQ208C9 is a member of the APEX 20K family of field-programmable gate arrays (FPGAs), delivering 100,000 typical gates and 4,160 logic elements (LEs) in a 208-pin PowerQuad QFP package. It integrates 53,248 RAM bits, four phase-locked loops (PLLs), and 159 user I/O pins, supporting 0.18-micron CMOS SRAM-based logic fabric with embedded system-on-a-chip (SoC) capability.

An FPGA (Field-Programmable Gate Array) is a semiconductor integrated circuit that can be configured by the customer or designer after manufacturing to implement any digital logic function. FPGAs sit in the broader hierarchy of programmable logic devices (PLDs) -> complex programmable logic devices (CPLDs) -> FPGAs -> SoC FPGAs, and are widely used as alternatives to application-specific integrated circuits (ASICs) for prototyping, low-volume production, and high-performance parallel processing tasks such as DSP, communications, and custom compute accelerators.

Key features of the EP20K100CQ208C9 include 4,160 logic elements, 26 embedded system blocks (ESBs) delivering 53,248 RAM bits, four PLLs for clock management, and a maximum of 159 user I/O. The device operates across commercial 0 to 70 C temperature range (the C9 speed grade) and supports in-system programmability via the IEEE 1149.1 JTAG interface and the Altera Passive Serial configuration scheme. The APEX 20K architecture combines look-up table (LUT) logic with embedded memory, enabling designers to integrate glue logic, FIFOs, and small register files on a single device.

Architecturally, the EP20K100CQ208C9 uses a MultiCore architecture introduced by Altera in 1999, distributing MegaLAB structures across the die and providing dedicated high-speed interconnect (FastTrack) for predictable timing. The four PLLs support clock multiplication, division, phase shifting, and frequency synthesis, simplifying board-level clock tree design for synchronous logic and source-synchronous interfaces.

Typical applications for the EP20K100CQ208C9 include telecommunications line cards, custom peripheral controllers for industrial automation, glue logic replacement for legacy ASICs, prototype validation of ASIC designs, PCI bridge implementations, and digital signal processing front-ends. The 208-pin PQFP package is well-suited for through-hole and socketed designs where rework and field replacement are valued over board density.

When designing with the EP20K100CQ208C9, engineers should use the Altera Quartus II (legacy) or MAX+PLUS II development environment for synthesis, place-and-route, and timing analysis. Configuration data must be loaded from a serial EEPROM or downloaded via JTAG; ensure your board supports the Passive Serial configuration mode and provides proper MSEL pin strapping for the chosen mode.

This page synthesizes distributor stock levels, drop-in same-package alternatives from the APEX 20K family, and practical design notes that go beyond the manufacturer datasheet, helping engineers evaluate the EP20K100CQ208C9 against modern FPGA alternatives.
