XC9536-15PC44C - 44-Pin I/O Expander | XMC
MPN: XC9536-15PC44C ✓ ActiveXC9536-15PC44C Overview
An I/O expander is a semiconductor peripheral that converts a relatively small serial interface into additional parallel digital lines. In the hierarchy of electronic components, the XC9536-15PC44C belongs to the logic IC family, where it sits between a host microcontroller and discrete input/output circuitry. This role can reduce the number of pins required on a controller, centralize logic-level interfacing, and simplify designs that need more digital status inputs or output controls than the host device provides directly.
The most established identifiers for this exact orderable configuration are its full MPN, XC9536-15PC44C; its 44-pin PC44 package designation; and its -15 configuration suffix. Detailed operating voltage, I/O count, serial-interface timing, output-current limits, logic thresholds, and temperature-range information are not present in the supplied verified record. These parameters must be confirmed in the manufacturer datasheet before the component is used in a production schematic or PCB design. The available information is therefore sufficient for product identification, but not for electrical sign-off.
The XC9536 series is structurally relevant to embedded control, industrial automation, communication equipment, data acquisition, and general-purpose expansion boards. In each case, the serial control path reduces parallel wiring while the 44-pin package exposes a larger I/O boundary than a typical small-outline microcontroller. The engineering decision still depends on matching the host bus, logic voltage, pin multiplexing, pull-up requirements, and output timing to the exact device documentation rather than assuming compatibility from the family name alone.
Designers should treat the XC9536-15PC44C as an unverified device until the official pinout, electrical table, recommended application circuit, and package drawing are obtained. PCB work should not begin from family-level assumptions because the PC44 package can contain power pins, address or control pins, communication pins, and general-purpose I/O pins whose exact assignments require document-level confirmation. Check that every exposed and unconnected pin matches the manufacturer land pattern.
Commercial availability and lifecycle status could not be established from the supplied distributor search because it returned a timeout error and no result URLs. Accordingly, price, stock, lead time, and lifecycle assertions remain unresolved. This page distinguishes the exact requested MPN from available family references and records what must be checked before procurement. For a quotation, request the exact suffix XC9536-15PC44C and confirm its manufacturer datasheet, date code, packing option, and authorized-distributor status.

Typical Applications
XC9536-15PC44C is suitable for 6 applications: Industrial Automation Control, Embedded Data Acquisition, Communication Equipment, Programmable Logic Control, Data Storage and Interface Expansion, Instrumentation and Test Equipment.
Industrial Automation Control
The XC9536-15PC44C can be evaluated for industrial automation modules that require more digital control and status lines than the primary controller exposes. Its 44-pin PC44 package provides a substantially larger connection boundary than a typical compact controller, while the I/O-expander role can keep the host bus wiring compact. Integration is appropriate only after the manufacturer datasheet confirms logic levels, output-drive capability, timing, and operating-temperature limits. Designers should also validate industrial noise immunity, isolated power behavior, surge exposure, and long-term availability rather than treating the family designation as complete qualification.
Recommended
Embedded Data Acquisition
The XC9536-15PC44C is relevant to data-acquisition equipment where sensors, status indicators, relays, or configuration switches require more digital lines than the host processor can provide directly. The expander architecture can reduce the number of connections between the controller and peripheral logic, while the 44-pin PC44 package offers a defined physical platform for a larger I/O map. For a working design, confirm the exact supported I/O count and multiplexed functions in the manufacturer datasheet. The system designer must also review pull-ups, input filtering, output speed, ground-return paths, and whether the acquisition chain requires isolation or level translation.
Recommended
Communication Equipment
The XC9536-15PC44C may be considered in communication equipment for module control, link-status monitoring, front-panel signaling, and peripheral routing. The I/O-expander function can offload discrete digital lines from a network processor, helping keep the host interface compact and reducing trace count in multi-function equipment. According to the manufacturer datasheet, the engineer must verify serial protocol compatibility, address behavior, timing margins, and I/O direction control before board release. High-speed communication designs should also examine clock crosstalk, return paths, connector ground structure, and separation between sensitive status signals and switching power nodes.
Recommended
Programmable Logic Control
The XC9536-15PC44C fits the general concept of a programmable logic controller peripheral by adding digital input and output capacity to a central controller. Such a configuration can support relay drivers, pushbuttons, mode selectors, and interlock-status inputs without assigning every line directly to a microcontroller. The exact XC9536-15PC44C suitability must be established from the manufacturer document because the supplied evidence does not confirm its I/O count, thresholds, or output ratings. Safety-related machinery also requires independent assessment of fail-safe states, isolation, diagnostic coverage, and compliance rather than relying on general-purpose logic-device availability.
Recommended
Data Storage and Interface Expansion
The XC9536-15PC44C can be evaluated for storage and interface systems that require discrete control lines for status indicators, configuration registers, power sequencing, or peripheral enables. Its 44-pin package provides a larger pin boundary for such mixed digital-control functions while preserving a common host-control architecture. Before implementation, the manufacturer datasheet must establish whether the required pins are available as general-purpose I/O and whether any pins have dedicated multiplexing requirements. PCB planning should also reserve proper bypass-capacitor locations, provide uninterrupted ground returns, and separate slow control traces from high-current switching paths.
Recommended
Instrumentation and Test Equipment
The XC9536-15PC44C is applicable to the concept of laboratory and field instrumentation that needs additional control lines for front-panel buttons, relays, range indicators, or peripheral enables. An I/O expander can reduce host-controller pin pressure while allowing the instrument architecture to remain modular. However, engineers must confirm the component's exact timing and output performance against the manufacturer's data, especially where controls influence measurement settling or safety interlocks. Layout should minimize coupling from relay and switching-supply nodes into digital inputs, provide adequate return paths, and include the manufacturer's recommended external components at the device pins.

Design Notes
Do not treat the shared PC44 package designation as proof that every XC9536 suffix is electrically interchangeable. The -15 target and the -5, -6, and -7 alternatives use different configuration codes, and the supplied data does not quantify their interface timing, operating grade, or I/O behavior. Obtain the current manufacturer comparison information and compare the exact suffix in the datasheet, including supply voltage, address configuration, logic thresholds, output-current limits, and temperature range.
Before laying out the PCB, create a pin-by-pin land pattern from the official XC9536-15PC44C package drawing rather than copying another PC44 variant. Confirm power, ground, host-interface, address or control, and general-purpose I/O assignments for every numbered pin. Reserve the manufacturer's required bypass-capacitor positions, maintain a low-impedance ground reference, and preserve clearances between external interface signals and nearby switching nodes.
Calculate the device and board power budget only after obtaining the exact operating and quiescent currents from the manufacturer datasheet. Include worst-case host-bus activity, output loading, supply tolerance, and adjacent-circuit losses rather than relying on a typical current value. A 44-pin surface-mount package does not by itself indicate adequate thermal performance; verify the package thermal data under the intended PCB copper and airflow conditions before release.
Use the manufacturer's recommended pull-ups, termination, and routing topology for the host interface. Keep clock and data traces short, route them over a continuous ground plane, and avoid sharing narrow paths with relay, motor, or switching-supply return currents. Where long external leads enter the board, use appropriate protection and filtering that preserve logic thresholds; confirm the expander's input slew-time and noise-immunity limits before selecting external components.
Compliance Information
The supplied verified search returned no manufacturer declaration, product page, or datasheet. Compliance must be confirmed for the exact MPN using current manufacturer documentation.
