XC9536XL-5VQ44C - 36-Macrocell 5 ns CPLD | AMD
Teilenummer: XC9536XL-5VQ44C ✓ AktivXC9536XL-5VQ44C Übersicht
A complex programmable logic device, or CPLD, is a user-programmable semiconductor that stores a logic design in nonvolatile memory. Its internal architecture connects groups of macrocells through a programmable interconnect. CPLDs occupy the hierarchy between simple fixed-function logic and FPGAs: they offer repeatable timing, straightforward configuration, and low power consumption, while offering less parallelism and capacity than a large FPGA. The XC9536XL family combines two 36V18 function blocks and 800 usable gates.
The -5 speed designation identifies the 5 ns propagation-delay grade, making this variant appropriate for general-purpose control logic requiring predictable operation. Its 36 macrocells can implement combinational equations, flip-flops, latches, and common bus-oriented control functions. In-system programmability allows a board to be programmed or reprogrammed without removing the device, while enhanced pin locking supports migration within the XC9500XL family and reduces PCB rework risk.
The XC9536 architecture is designed for general-purpose programmable logic integration and supports product-level test functions. Because the device is configured from nonvolatile memory, it powers up in its programmed state without requiring an external configuration loader. The 44-pin surface-mount package also provides enough I/O and power connections for control-plane logic, interface adaptation, state machines, and fixed-format data processing. Programming normally uses the established Xilinx/AMD CPLD development flow, with the appropriate device and package settings selected in the project.
Typical uses include industrial control and sequencing, instrumentation, communication-interface glue logic, test-equipment control, embedded-system bus decoding, and compact embedded controllers. The device is particularly useful when a design must retain a small package, simple deterministic timing, and repeatable pin assignments while still allowing late design revisions. It can also consolidate several gate-level functions into one programmable component, reducing discrete logic count.
For PCB implementation, preserve the package outline, exposed or thermal pad requirements, pin numbering, and power-decoupling layout specified by the AMD datasheet. Confirm the selected programmer, cable, and configuration file support the exact XC9536XL device. Timing-sensitive designs should use the 5 ns grade in worst-case system timing analysis and allow for input-slew, output-load, and output-enable effects rather than relying on the propagation-delay grade alone.
This product record combines the AMD DS058 device characteristics with practical package, programming, replacement, and design guidance. It also distinguishes true same-footprint XC9500XL alternatives from broader functional CPLD equivalents whose pinouts and voltage characteristics may require a different PCB design.

Industrial Control and Sequencing
The XC9536XL-5VQ44C is well suited to compact industrial control logic because its 36 macrocells and 800 usable gates can consolidate sequencing, interlock, alarm, and state-management functions. The 5 ns propagation-delay grade provides useful timing margin for deterministic control paths, while the 44-pin VQFP package simplifies board-level integration. Designers can implement counters, debounce logic, command decoders, and machine-state machines without distributing equivalent functions across multiple fixed-logic devices.

Test and Measurement Instrument Control
In test and measurement equipment, the XC9536XL-5VQ44C can implement instrument sequencing, front-panel decoding, status indication, and command routing. Its two 36V18 function blocks provide 36 macrocells for flip-flop and combinational logic, while nonvolatile configuration preserves the control design between power cycles. The 5 ns grade supports deterministic interconnects in a compact 44-pin package, making it useful when measurement data is handled by a separate processor and the CPLD manages instrument-side control logic.
Empfohlen
Communication Interface Adaptation
The XC9536XL-5VQ44C can bridge fixed-format communication signals through programmable framing, byte assembly, parity generation, and protocol sequencing. The 36 available macrocells allow several related finite-state functions to be consolidated, and the 5 ns grade helps constrain combinational delays between interface stages. Its in-system programming capability supports firmware and board revisions after the initial design, provided the exact configuration file and pin assignments remain valid for the 44-pin package.

Embedded-System Bus Decoding
For embedded control boards, the XC9536XL-5VQ44C can implement address decoding, chip-select generation, interrupt arbitration, and peripheral interconnect timing. Its two 36V18 function blocks offer a practical balance between programmable capacity and deterministic routing, and the 5 ns grade is useful for short control paths around a host processor. Nonvolatile configuration allows the logic to operate immediately after reset, while in-system programming helps maintain a common pin-compatible platform across design revisions.

LED Display and Panel Control
The XC9536XL-5VQ44C can control LED indicators, display multiplexing, keypad scanning, and panel-status logic in a compact embedded display. Thirty-six macrocells are sufficient for multiple multiplexed scan counters and indicator decoders, while the 5 ns propagation-delay grade helps maintain predictable update timing. The 44-pin package offers a practical balance of logic and I/O for small panels, and the nonvolatile configuration preserves display sequencing after power restoration.

Programmable Security and Access Logic
The XC9536XL-5VQ44C can implement access-control sequences, lock-state machines, key-event debouncing, and alarm-enable logic in equipment security panels. Its 36 macrocells support multiple registered stages and combinational decision paths, while the 5 ns grade helps minimize uncertainty in response timing. Because the design is held in nonvolatile memory, the panel can enforce its configured access sequence immediately after power-up without depending on a separate host controller for every decision.

Designhinweise
Use the AMD DS058 package drawing and pin-description table as the controlling layout references for the 44-pin VQFP. Preserve the package outline, pin-1 orientation, lead pitch, solder-mask clearance, and exposed thermal-pad requirements. Place the CPLD close to the devices whose signals it decodes or controls, and route clock, reset, programming, and high-speed interface nets away from switching-node traces to reduce coupling.
Follow the DS058 recommended-decoupling network exactly, including capacitor value, voltage rating, dielectric type, and placement. Place the required capacitors directly beside the associated power and ground pins rather than sharing a distant bulk capacitor. Confirm that every supply rail remains within its specified operating range under transient conditions, and provide a low-impedance ground return to minimize simultaneous-switching noise.
Do not assume that another XC9536XL speed or ordering suffix is an automatic substitute. Compare the package drawing, temperature grade, pin definitions, supply limits, and speed grade, then re-run timing analysis using the slower grade where applicable. Also select the exact package and suffix in the programming project so that pin constraints and configuration metadata match the physical device.
Treat the 5 ns propagation-delay grade as a component characteristic rather than a complete system-timing guarantee. Timing analysis should include input-slew rate, output loading, interconnect delay, setup and hold requirements, and clock distribution. For externally exposed or high-fanout signals, add suitable source termination, series damping, or isolation where edge-rate analysis shows ringing or overshoot.
Keep the in-system programming interface accessible and route programming pins away from high-current switching paths. Avoid placing test-point or mechanical features that interfere with programmer access. Because the XC9500XL architecture supports pin locking and family migration, maintain a disciplined constraint and pin-assignment strategy so a speed-grade or density-family change does not require unintended board changes.
Compliance-Informationen
The CPLD is not an automotive-qualified device based on the ordering designation. RoHS, REACH, lead-free, halogen-free, and conflict-minerals status require confirmation from the current AMD product documentation or supplier declaration.
