No detailed pinout data available for EP910LI-15.
Refer to the datasheet for full pin configuration.
Typical Applications
EP910LI-15 is suitable for 6 applications: Industrial Control Logic, Legacy Peripheral Interface, Board-Level State Machine, Test and Measurement Control, Automotive and Vehicle Electronics Support, Legacy Board Repair and Obsolescence Support.
Industrial Control Logic
EP910LI-15 fits industrial control logic where moderate programmable integration can replace multiple fixed-function logic devices. Its 12 dedicated inputs and 24 configurable input/output lines provide 36 user-signal resources for limit-switch decoding, machine-state sequencing, actuator-control interfaces, and interlock logic. The 4.5 V to 5.5 V supply range supports common regulated 5 V control rails, while the -40 °C to +85 °C operating range covers industrial ambient requirements. A key benefit is consolidation: combinational, registered, and timing logic can be implemented in one Classic EPLD, reducing board area and interconnection risk. Engineers should still verify the 15 ns timing grade, macrocell architecture, configuration method, and I/O electrical characteristics in the manufacturer datasheet before using it in a new safety or high-availability controller.
Recommended
Legacy Peripheral Interface
EP910LI-15 can serve as a programmable interface bridge for legacy 5 V peripherals, including address decoding, wait-state generation, register selection, and protocol adaptation. The device’s 12 dedicated inputs can receive board-select, interrupt, clock, and control signals, while the 24 input/output lines can interface memory-mapped or control buses. Operating from 4.5 V to 5.5 V allows use with conventional 5 V interface logic, and the Classic EPLD architecture provides a fixed, integrated way to implement glue logic that might otherwise require several packages. Before replacement, compare bus direction, voltage thresholds, propagation delay, package terminals, and programming behavior. The supplied web data confirms the device family and resources but does not provide full electrical-characteristic or timing tables, so a drop-in decision requires documentation review.
Recommended
Board-Level State Machine
EP910LI-15 is a practical candidate for board-level state machines that coordinate startup, reset, mode selection, service sequencing, and fault handling. Its 36 user-signal resources, consisting of 12 dedicated inputs and 24 configurable I/O lines, allow multiple external events to participate in registered and combinational control logic. The 15 ns speed designation supports timing-oriented designs, but the exact meaning must be confirmed from the EP910 datasheet because it is not a complete timing specification by itself. The -40 °C to +85 °C range is useful for equipment exposed to industrial temperature variation. Use the original Altera design environment or an archived compatible toolchain, create a pin-accurate constraint file, and perform static timing analysis on the fitted design before releasing the PCB.
Recommended
Test and Measurement Control
EP910LI-15 can consolidate control sequencing, range selection, trigger routing, and instrument-status encoding in test and measurement equipment. The 12 dedicated inputs are useful for trigger, clock, range, and enable inputs, while the 24 configurable I/O lines can control relays, analog-switch paths, indicators, or measurement subcircuits. A 4.5 V to 5.5 V supply range simplifies use in 5 V instrument architectures, and the -40 °C to +85 °C range supports industrial laboratory and factory environments. The Classic EPLD format is valuable when deterministic, board-level logic is preferred over a larger FPGA. Confirm the actual I/O drive, input thresholds, power-up behavior, timing limits, and configuration requirements because the supplied search data does not include those detailed electrical values.
Recommended
Automotive and Vehicle Electronics Support
EP910LI-15 should not be selected for automotive safety-critical electronics without explicit qualification evidence. Its verified operating temperature range of -40 °C to +85 °C is relevant for many vehicle environments, but the source does not state AEC-Q100 qualification, PPAP, or automotive quality status. The device may be considered for non-safety, legacy support work or bench equipment, while automotive programs should use a part with documented automotive qualification. For any vehicle application, review 4.5 V to 5.5 V operation, 12 dedicated inputs, 24 configurable I/O lines, speed grade, PQCC44 mechanical construction, electrical transients, and long-term supply continuity. Do not treat the temperature range as proof of AEC-Q100 compliance.
Recommended
Legacy Board Repair and Obsolescence Support
EP910LI-15 is especially relevant to legacy board repair, discontinued-equipment support, and inventory replacement. The verified 4 Star Electronics result indicates that some inventory may ship the same day when ordered by 2:00 p.m. PST, while other suppliers present rapid-quote or market-intelligence listings. The correct replacement process is to verify the original package, date code, terminal numbering, speed grade, temperature range, and configuration before approving a substitute. EP910LI-12 and EP910LC-40 appear in the supplied cross-reference results, but functional equivalence is not the same as guaranteed drop-in compatibility. Purchase only through suppliers willing to provide traceability and inspection evidence, and perform continuity, programming, and functional testing on received units.

Design Notes
Use a regulated 4.5 V to 5.5 V rail and place local bypass capacitors close to the EP910LI-15 power terminals. The verified data confirms the supply range but does not provide the required capacitor values, current consumption, or power-up sequence. Start with the manufacturer’s EP910 reference implementation and add a documented decoupling network based on the final I/O switching load. Confirm that all 5 V input signals remain within the device’s specified input thresholds and that output loading is checked against the datasheet’s electrical tables. Do not assume that a 5 V rail alone guarantees correct programmable-logic operation during configuration or reset.
Design the PQCC44 ceramic carrier with the assembly process in mind. The verified source identifies a 44-terminal J-lead ceramic chip carrier, but it does not provide thermal resistance, junction-temperature limits, or assembly recommendations. Use the manufacturer package drawing and current reliability data to establish allowable process temperatures, terminal-planarity checks, and inspection criteria. Keep high-current or high-dissipation circuitry away from the device, and provide the copper and airflow needed by the surrounding board design where appropriate. Because the exact thermal data is not supplied, do not convert an assumed thermal-resistance value into a guaranteed junction-temperature calculation.
Verify the PQCC44 land pattern from the official package drawing before PCB release. The verified web result confirms 44 terminals and a J-lead ceramic chip carrier, but it does not include terminal names or recommended pad dimensions. Check pin-1 orientation, terminal numbering, solder-mask-defined or non-solder-mask-defined land pattern, coplanarity, and clearance against nearby components. Preserve short connections for clocks, resets, and critical control paths, and add test points for configuration, power, and major logic interfaces. A functional-equivalent listing does not remove the requirement to prove that the selected part has the same terminal assignment and mechanical footprint.
Do not confuse the -15 speed designation with a complete timing guarantee. The supplied data identifies a 15 ns speed grade, but the EP910 family datasheet should be used to verify propagation delay, setup and hold times, clock requirements, and output loading. Similarly, a functional-equivalent cross-reference does not automatically prove drop-in compatibility: inspect package, pinout, supply limits, temperature grade, programming interface, and configuration behavior. For legacy procurement, confirm date code, manufacturer marking, traceability, and whether the supplier’s inventory is new, surplus, or refurbished. Program and functionally test a sample lot before relying on a substitute in production equipment.
Compliance Information
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or AEC-Q100 status. The device is a legacy programmable-logic component; compliance claims must be confirmed from the original manufacturer documentation and supplier certificates.
