Typical Applications
EP20K100CT144C7ES is suitable for 7 applications: Telecommunications Line Cards, Industrial Control and Factory Automation, Networking Bridges and Routers, Low-Volume ASIC Prototyping, Military and Aerospace Avionics, High-Speed Glue Logic, Legacy Design Maintenance and Spares.
Telecommunications Line Cards
The EP20K100CT144C7ES's 100K gates and 4,160 logic elements provide sufficient density for telecom line card glue logic, framer interfacing, and protocol conversion between E1/T1 and backplane serial links. The MultiVolt I/O supports direct 5 V bus interfacing alongside 2.5 V core logic, eliminating level shifters. With 93 user I/O pins and 53,248 bits of embedded RAM, the part handles packet buffering and address lookup functions in mid-density designs. Designers benefit from the FastTrack interconnect's predictable timing for synchronous telecom protocols.
Recommended
Industrial Control and Factory Automation
Factory automation systems leverage the EP20K100CT144C7ES for motor control state machines, PLC interface logic, and real-time I/O aggregation. The 53,248 bits of embedded RAM via EABs provide dual-port buffering for sensor data streams, while 93 I/O pins handle multiple encoder, limit-switch, and actuator signals. The 144-LQFP package supports standard surface-mount assembly in industrial controllers. Industrial designers value the JTAG-based in-system programmability for field firmware updates without removing the part from the board.
Recommended
Networking Bridges and Routers
Mid-range bridges and routers use the EP20K100CT144C7ES to implement custom packet classification, queue management, and MAC-layer acceleration. The embedded array blocks (EABs) deliver up to 2,048 bits each of dual-port RAM for FIFO structures handling packet bursts. The 2.5 V core combined with 3.3 V and 5 V MultiVolt I/O enables direct connection to PHY transceivers and legacy backplane logic. The 93 I/O count accommodates multiple MII/RMII/GMII interfaces for multi-port Ethernet designs.
Recommended
Low-Volume ASIC Prototyping
Engineers prototyping ASIC designs use the EP20K100CT144C7ES to validate RTL before tape-out. The 100K-gate capacity, combined with Altera Quartus design software support and JTAG-based configuration, allows rapid iteration cycles. The 53,248 bits of block RAM approximate typical ASIC memory macro densities for verifying memory-mapped interfaces. Designers can map logic to the 4,160 LEs while using EABs for wide datapath registers, mirroring planned ASIC architectures.
Recommended
Military and Aerospace Avionics
Legacy avionics subsystems still rely on the EP20K100CT144C7ES for mission computer I/O expansion and bus protocol bridging between MIL-STD-1553 and ARINC 429 interfaces. The part's mature silicon and predictable FastTrack routing simplify DO-254 certification documentation. Note that this specific variant is commercial temperature (0C to +85C); for full military temperature range (-55C to +125C), designers should specify the EQ or EB extended-grade variants. The 144-LQFP package suits ruggedized PCB assemblies with underfill.
Recommended
High-Speed Glue Logic
The EP20K100CT144C7ES bridges microprocessors to legacy peripherals in mixed-voltage systems where dedicated glue-logic ASICs would be uneconomical. Its MultiVolt I/O directly interfaces 5 V memory, 3.3 V DSPs, and 2.5 V processor cores without external level shifters. The 4,160 logic elements handle address decoding, wait-state generation, and interrupt steering, while the 93 I/O pins accommodate wide bus interfaces. JTAG-based configuration simplifies board bring-up versus mask-ROM glue logic.
Recommended
Legacy Design Maintenance and Spares
Long-lifecycle systems including medical imaging, railway signaling, and industrial process controllers continue to require the EP20K100CT144C7ES for sustaining engineering and spare-parts replacement. With NRND status limiting new production, distributors maintain buffer stock for service contracts. Engineers maintaining these systems use the part to repair field-deployed units where redesign is not feasible, often pairing it with the standard EP20K100CT144C7 variant when the ES suffix is not strictly required.

Key Differentiators
- Same-package, same-silicon production alternative without ES suffix (vs EP20K100CT144C7)
- MultiVolt I/O enables mixed-voltage board designs (vs EP20K100CF144C7ES)
- 144-LQFP enables standard SMT assembly vs BGA alternatives (vs EP20K100CB356C7)
Design Notes
Power sequencing is critical for the EP20K100CT144C7ES. The 2.5 V VCCINT rail must reach its valid range (2.375 V to 2.625 V) before I/O bank supplies (VCCIOx) drive signals into the pins. Reverse sequencing can cause I/O structures to back-power the core, potentially triggering latch-up on legacy 0.18 Β΅m CMOS. Altera's APEX-20K datasheet recommends a monotonic power ramp; in-system configuration via JTAG should only be initiated after all rails are stable. Decouple each VCCINT pin with a 0.1 Β΅F ceramic plus a bulk 10 Β΅F tantalum within 25 mm of the package.
The 144-LQFP package has a 0.5 mm pitch and requires careful PCB layout. Use 4-layer stackup with dedicated ground and power planes. Route all 8 VCCIO bank supplies with wide traces (>= 0.5 mm) and place a 0.1 Β΅F decoupling capacitor on every VCCIO pin within 5 mm. The 20 x 20 mm package body benefits from thermal relief pads under the lead frame; ensure at least 8 thermal vias in the center pad area to spread heat from the die to inner ground planes. JTAG chain routing (TCK, TMS, TDI, TDO) should be kept short and length-matched to within 25 mm to avoid signal integrity issues at high configuration clock rates.
Do not confuse the EP20K100CT144C7ES (144-LQFP) with the EP20K100CQ240C7ES (240-QFP). The 240-pin QFP variant has more I/O pins and a different pinout, making it non-drop-in despite identical silicon. Also note the 'ES' suffix indicates an engineering sample revision - for production deployments, prefer the standard EP20K100CT144C7 unless the ES revision is explicitly required. Finally, MultiVolt I/O levels must be set per bank via VCCIO supply voltage; mixing 5 V and 1.8 V on the same bank without proper VCCIO selection will damage the I/O cells. Consult the APEX-20K datasheet pin tables before board layout.
Compliance Information
RoHS compliant and lead-free per Besenchips product listing. REACH, halogen-free status, and conflict minerals compliance not specified in verified data. AEC-Q100 not applicable - this is a commercial-grade FPGA; automotive designs require EQ/EB extended-temperature variants.
