XC9536-15VQ44C - 36-Macrocell 15ns CPLD | Xilinx
Teilenummer: XC9536-15VQ44C ✗ AbgekündigtXC9536-15VQ44C Übersicht
A CPLD, or Complex Programmable Logic Device, is a programmable logic semiconductor that sits between fixed-function logic gates and larger programmable logic arrays. Its macrocells and programmable interconnect combine deterministic timing with nonvolatile configuration memory. In the system hierarchy, the XC9500 family belongs to the CPLD and PLD class, then to programmable logic devices, integrated circuits, and semiconductors. This makes it useful for consolidating control, decoding, interface, and glue-logic functions on industrial, communications, and legacy embedded systems.
The XC9536 provides 5 ns pin-to-pin logic delays for the underlying family and a maximum 15 ns propagation delay for this speed grade. It offers 34 user I/O pins, in-system programmability, and a minimum endurance of 10,000 program or erase cycles. Its 800 usable gates provide substantially more integration than individual discrete logic gates while retaining the simple tool-supported programming model associated with the XC9500 family.
The XC9536 architecture uses two 36V18 function blocks, each containing 18 macrocells. Fast FLASH configuration cells retain the programmed logic without volatile SRAM, while the five-volt I/O environment supports systems designed around legacy 5 V logic families. The exact package is a 44-pin VTQFP; the verified snippets also describe the device as a square TQFP-family surface-mount package with gull-wing terminals.
Typical uses include industrial control and instrumentation, legacy communications interfaces, address decoding, programmable I/O expansion, embedded system glue logic, and test equipment. The 36 macrocells are particularly effective for multi-bit decoders, state machines, control registers, bus arbiters, and compact protocol interfaces where separate logic ICs would increase component count.
Designers should treat programming, 5 V supply sequencing, input overshoot, and output drive as the main implementation concerns. The verified datasheet limits external I/O voltage to VCCINT plus 4.0 V and specifies restricted transient undershoot and overshoot conditions. Before layout release, verify the selected XC9536 programmer, the legacy pinout, and all board-level signal-integrity requirements.
This product record combines the verified manufacturer-family specifications, distributor availability information, package details, and same-family replacement guidance into an engineering-focused resource. It also identifies the limits of available drop-in data rather than presenting unverified cross-brand parts as direct replacements.

Typische Anwendungen
XC9536-15VQ44C ist geeignet für 6 Anwendungs: Industrial Control and Automation, Legacy Communications Interface Control, Address Decoding and Bus Interface Glue, Programmable I/O and Test Fixture Control, Legacy Instrumentation Control, Embedded System Glue Logic.
Industrial Control and Automation
The XC9536-15VQ44C fits compact 5 V industrial control blocks that combine state-machine logic, command decoding, interlocks, and interface conditioning. Its 36 macrocells and 800 usable gates can consolidate several small fixed-function devices, while the 34 user I/O pins provide direct access to switches, sensors, and actuator-command signals. The 15 ns propagation-delay class is suitable for many control paths that do not require the XC9536-6VQ44C timing margin. Because the exact operating-temperature range is unavailable in the supplied records, industrial deployment requires documentary environmental verification and appropriate qualification for the finished system.
Empfohlen
Legacy Communications Interface Control
The XC9536-15VQ44C can implement protocol framing, baud-rate selection, command filtering, and bus arbitration in legacy communications equipment. Two 36V18 function blocks provide 36 configurable macrocells, enough for multi-state control logic and register-based interfaces without requiring a large FPGA. Its 34 user I/O pins are useful for parallel data, chip selects, and handshake signals. The maximum 15 ns pin-to-pin delay supports many moderate-speed control paths, but designers must calculate setup and hold margins against the actual transceiver and confirm that the 5 V interface environment matches every connected component.
Empfohlen
Address Decoding and Bus Interface Glue
The XC9536-15VQ44C is well suited to address decoding, chip-select generation, interrupt routing, and peripheral interconnect logic in older 5 V embedded systems. Thirty-six macrocells allow multiple decode branches and registered control outputs to be implemented together, reducing reliance on separate gate packages. The in-system programming capability permits functional updates without removing the device, provided the board preserves the required programming interface and power. Because this is a legacy 5 V CPLD, engineers should verify that external bus drivers do not exceed the specified I/O-voltage limits and should reanalyze propagation delay against the original system clocking assumptions.
Empfohlen
Programmable I/O and Test Fixture Control
The XC9536-15VQ44C can provide configurable I/O expansion and sequencing for test fixtures, instrumentation, and board-isolation systems. Its 34 user I/O pins allow relay-control outputs, status inputs, and pattern-generation signals to share one programmable device, while 36 macrocells support timing-state machines and exception handling. The 15 ns maximum propagation delay is appropriate for many low- and medium-speed fixture sequences, but setup timing still depends on the external driver and fixture load. Validate signal integrity, programmed test vectors, and programming access before tying the CPLD into a production tester.
Empfohlen
Legacy Instrumentation Control
The XC9536-15VQ44C offers enough programmable logic for measurement front ends that require mode control, range selection, trigger conditioning, and status reporting. The 800 usable gates and 34 I/O pins can consolidate control logic around an external sensor or converter, while in-system programming supports configurable test modes. Its 5 V internal range matches many older measurement architectures, but the verified record does not establish the operating-temperature grade or modern compliance status. Therefore, use the device only where legacy availability justifies verification, and keep high-accuracy conversion and signal-conditioning functions in dedicated analog components.
Empfohlen
Embedded System Glue Logic
The XC9536-15VQ44C is useful for boot sequencing, watchdog handling, interrupt arbitration, and peripheral configuration in embedded systems built around legacy processors. Thirty-six macrocells can combine a compact state machine with bus decode and fault-latch functions, avoiding a larger programmable-logic device. Its 15 ns delay class is generally appropriate for supervisory and asynchronous control paths, while high-speed datapaths should remain with the processor or dedicated logic. The main design risk is legacy-tool integration, so engineers must verify programmer availability, configuration-file support, and the exact board pinout before committing to a new design.

- Nonvolatile in-system reconfiguration (vs. XC9536-6VQ44C)
Designhinweise
Design the XC9536-15VQ44C around a stable 4.75 V to 5.25 V internal supply and place the required bypass capacitors close to the power pins according to the manufacturer datasheet. The verified specification permits external I/O voltage only up to VCCINT plus 4.0 V. Check every connected device so a powered peripheral cannot back-power an unpowered CPLD through an input or output path. Power sequencing, input leakage, and bus contention must be evaluated together because a valid 5 V supply range alone does not make mixed-power interfaces safe.
Treat the verified transient limits as hard design boundaries. DC undershoot below ground must be limited to 0.5 V or 10 mA, whichever is easier to achieve, while transition overshoot to +7.0 V and undershoot to -2.0 V is permitted only for less than 10 ns and with forcing current limited to 200 mA. These conditions do not authorize arbitrary ringing. Use controlled edge rates, appropriate termination or damping where needed, and verify the worst-case voltage at the device pin rather than only at the driver.
Do not substitute a different XC9536 suffix solely because its package looks similar. The XC9536 family includes multiple speed grades and package options, and the verified alternatives list includes both PC44 and VQ44 forms. Confirm the exact 44-pin VTQFP footprint, pin-1 orientation, programming interface, power pins, and I/O ratings against the manufacturer PDF. Also verify that the replacement toolchain and configuration file support the selected speed grade. For a timing-sensitive board, rerun static timing rather than assuming that a faster or slower grade preserves the original timing margin.
Preserve the in-system programming path when laying out the board. Keep programming-mode control, clock, data, and configuration-status routing accessible, and observe any separation or isolation guidance in the manufacturer datasheet. Avoid long unprotected programming traces next to switching nodes or high-impedance analog inputs. If legacy board revisions are being cloned, compare pad geometry and pin numbering directly rather than relying on a generic TQFP footprint, since the supplied records describe a 44-pin VTQFP rather than the more common 48-pin TQFP library entry.
Compliance-Informationen
The verified listing states that the device is RoHS non-compliant and contains lead. REACH, halogen-free, and conflict-minerals evidence was not supplied. The operating-temperature range and automotive qualification status were also not verified.
