EP20K100CT144C7 Visão geral
A Field Programmable Gate Array (FPGA) is a semiconductor integrated circuit whose digital logic function is defined by the user after manufacturing. Within the broader programmable logic hierarchy, an FPGA sits above CPLDs in both logic density and I/O capability and below ASICs in unit cost but far above in design flexibility. The APEX-20K family specifically introduced ESB blocks that can be configured as RAM, ROM, CAM, or product-term logic, allowing system-on-chip integration in a single device.
Key features of the EP20K100CT144C7 include 100K typical gates, 53,248 system gates, 4,160 logic elements, 53248 flip-flops, 53248 maximum memory bits, and 93 user I/O pins. The device operates from a 1.8V core supply with 3.3V multi-voltage I/O support, and is fabricated on a 0.18-micrometer CMOS process. The commercial speed grade C7 places it at the slower-but-cost-optimized end of the APEX-20K speed spectrum.
Architecturally, the EP20K100CT144C7 combines MegaWizard-style MegaLAB structures (groups of 16 Logic Elements) with Embedded System Blocks distributed in a columnar arrangement, allowing deterministic timing and efficient memory implementation. The 144-pin TQFP package exposes 93 user I/O pins while consuming 31.4 mm of board area per side - acceptable for legacy designs but no longer recommended for new high-density layouts.
Typical applications include telecommunications infrastructure, industrial control, ASIC prototyping, glue-logic consolidation, and DSP preprocessing. Engineers also use APEX-20K devices for PCI bus bridging, custom peripheral controllers, and gate-array prototyping where NRE cost is prohibitive.
When designing with this device, ensure Quartus or MAX+PLUS II support is available because newer Quartus versions have dropped APEX-20K synthesis support - legacy toolchains are required. The 144-TQFP package is also obsolete for new PCB designs; consider migrating to Cyclone or MAX II families for ongoing production.

Aplicações típicas
EP20K100CT144C7 é adequado para 6 aplicaçãos: ASIC Prototyping and Validation, Telecommunications Infrastructure, Industrial Control and Automation, DSP Preprocessing and Glue Logic, Custom Peripheral Controllers, Legacy Computing Platform Glue Logic.
ASIC Prototyping and Validation
The EP20K100CT144C7's 100K typical gates and 4,160 logic elements make it a strong ASIC prototyping vehicle for mid-complexity gate-array emulation. Engineers map RTL designs into APEX-20K ESB blocks and LUT-based MegaLAB structures to validate functionality before committing to mask NRE. The 93 user I/O pins allow real-world pin-bound ASIC validation, and the C7 speed grade is acceptable for functional verification where timing closure is enforced by the prototype, not the silicon. Compared to simulation, hardware emulation in this FPGA runs 100x-1000x faster and exposes clock-domain issues that RTL simulation cannot. The 144-TQFP package remains thermally manageable for bench-top validation, and Quartus synthesis flows are well-documented for ASIC-equivalent constraint files.
Recomendado
Telecommunications Infrastructure
The EP20K100CT144C7 was widely deployed in legacy telecom infrastructure for protocol bridging, glue-logic consolidation, and custom serial-interface controllers. Its multi-voltage I/O (1.8V/2.5V/3.3V) allows direct interfacing to TTL and CMOS peripherals common in telecom backplane designs, while the ESB blocks implement FIFOs and protocol state machines efficiently. The 53,248 flip-flops provide sufficient sequential density for serial-bit processing and packet-header parsing. Telecom equipment typically runs in environmentally controlled racks, so the commercial 0C to +85C operating range of this part is acceptable. Legacy systems still in service today may require this FPGA for repair and refurbishment when original stock is unavailable.
Recomendado
Industrial Control and Automation
Industrial control systems use the EP20K100CT144C7 to consolidate discrete logic, implement custom motor-control state machines, and bridge legacy fieldbus protocols. The 93 user I/O pins accommodate multiple encoder channels, opto-isolated inputs, and PWM outputs commonly required by PLC and motion-control designs. The on-chip ESB blocks can implement CAM tables for part-number lookup or product-routing, replacing external parallel PROMs and reducing BOM cost. The 144-TQFP package supports through-hole and surface-mount assembly processes used in industrial-grade PCB manufacturing. For new industrial designs, an extended-temperature variant like the EP20K100ET144C7 should be considered to operate reliably in -40C factory-floor environments.
Recomendado
DSP Preprocessing and Glue Logic
The EP20K100CT144C7 served as a DSP co-processor and glue-logic consolidator between microprocessors, DSP chips, and analog front ends. Its logic-element density supports up to 53,248 flip-flops, sufficient for implementing custom FIR filter datapaths, gain-control loops, and signal-routing matrices. The ESB blocks can be configured as dual-port RAM for sample buffering between ADC and DSP blocks, eliminating external SRAM. Multi-voltage I/O allows direct connection to legacy 5V DSPs without level shifters. Designers frequently pair this FPGA with TI TMS320C6x or Analog Devices SHARC DSPs in audio equipment, sonar processing, and radar preprocessing pipelines where it remains in service today.
Recomendado
Custom Peripheral Controllers
Engineers built custom peripheral controllers with the EP20K100CT144C7 for legacy PCI, ISA, and VME bus architectures, where its logic density allows full bus-master state machines and DMA engines in a single chip. The 144-TQFP package was preferred over BGA alternatives for prototype boards using through-hole assembly or low-cost 4-layer PCB processes. Bus-cycle timing could be precisely tuned using the C7 speed grade's predictable setup/hold characteristics, and the JTAG port simplified board-level bring-up. Legacy industrial PCs, medical imaging systems, and military embedded platforms still rely on this device for backward-compatible peripheral designs.
Recomendado
Legacy Computing Platform Glue Logic
The EP20K100CT144C7 was a popular glue-logic device in late-1990s and early-2000s computing platforms, consolidating address decoding, wait-state generation, interrupt prioritization, and bus arbitration that previously required multiple 74-series TTL chips. Its 4,160 logic elements can absorb what would have been a board full of discrete gates, reducing board area, improving reliability, and easing design changes via firmware updates. Modern computing platforms no longer use this device, but it remains in service in legacy point-of-sale terminals, avionics test equipment, and military command-and-control systems where redesign certification cost is prohibitive. Engineers maintaining these systems rely on authorized aftermarket supply chains.

Principais diferenciais
- C7 speed grade at the cost-optimized end of the APEX-20K spectrum (vs EP20K100CT144C8)
- Commercial temperature range matches standard industrial environments (vs EP20K100ET144C7)
- Mid-density APEX-20K with 93 user I/O in 144-TQFP (vs EP20K100CQ208)
Notas de projeto
The APEX-20K family is not supported by Quartus Prime 17+ - use MAX+PLUS II 10.23 or Quartus II Service Pack 2 (legacy). Synthesizing with newer Quartus will fail at the analysis stage. Confirm tool availability before starting a design or maintenance project, as Intel does not officially support these tools on current operating systems. Virtual machines running Windows XP or Windows 7 may be required to host MAX+PLUS II for bitstream generation.
The EP20K100CT144C7 requires separate VCCINT (1.8V core) and VCCIO (1.8V/2.5V/3.3V I/O bank) supplies. All four VCCINT pins and all VCCIO pins must be properly decoupled with 0.1uF ceramic capacitors placed within 5mm of each supply pin, plus a 10uF bulk capacitor per rail. Missing decoupling causes configuration failures and unreliable JTAG communication. Power sequencing is not required between VCCINT and VCCIO for the APEX-20K family, simplifying supply design.
Estimated: The 144-TQFP package has a thermal resistance theta_JA of approximately 35 C/W on a 4-layer JEDEC test board with 1oz copper. At maximum static power dissipation of approximately 0.5W under typical use (1.8V core, ~30% utilization), the junction rises only 17.5C above ambient, well within commercial temperature limits. No external heatsink is required. For dense designs approaching full logic utilization, ensure the PCB has at least 4 signal layers with internal ground planes beneath the device for heat spreading.
Configure JTAG chain on the board so that the EP20K100CT144C7 is accessible in-system via TCK/TMS/TDI/TDO. Pull TMS high through a 1kohm resistor to VCCIO1 to keep the TAP controller in reset during power-up. Connect nCONFIG to VCCIO1 via 1kohm pull-up and to a configuration source. The CONF_DONE pin must be open-drain capable (the device drives it low during configuration) and pulled high through a 1kohm resistor for reliable boot.
