XC9536-10PC44I - 36-Macrocell 10 ns CPLD | AMD | Industrial
N.º de pieza: XC9536-10PC44I ✗ Fin de vidaXC9536-10PC44I Descripción general
A complex programmable logic device, or CPLD, is a configurable semiconductor that combines nonvolatile programmable logic with a structured macrocell architecture. In the broader semiconductor hierarchy, a CPLD is a programmable logic device positioned between simple fixed logic and larger FPGAs. Its deterministic timing, electrically erasable nonvolatile configuration, and in-system programmability make it useful where logic must be updated without replacing the assembled PCB.
Key device features include eight 36V18 function blocks, 36 macrocells, approximately 800 usable gates, 34 I/O pins, and in-system programming with a minimum of 10,000 program or erase cycles. The -10 speed designation corresponds to a maximum propagation delay of 10.0 ns. The device also supports parallel programming of multiple XC9500 devices, simplifying board-level configuration when several related CPLDs are present.
The XC9500 architecture uses product-term-based logic rather than a sea of arbitrary lookup-table and routing resources. Each macrocell can be assigned to high-performance or low-power operation, while unused product terms and macrocells can be deactivated by design software. This makes configuration tools, device pin assignment, and unused I/O treatment important parts of implementing a reliable design.
Typical uses include industrial control logic, interface adaptation, legacy peripheral consolidation, data acquisition, test equipment, embedded control, and general-purpose glue logic. The 34 available I/Os provide connectivity for control signals, buses, status indicators, and programmable digital interfaces while keeping the design in a compact 44-pin surface-mount package.
The principal design consideration is timing closure across every path between I/O pins and macrocell outputs. Designers should use the manufacturer's timing tools and the 10 ns device rating to analyze external setup and hold requirements, interconnects, and registered system paths. Industrial-temperature operation, programming voltage, signal levels, and unused-pin treatment must also be checked against the XC9500 family documentation.

Aplicaciones típicas
XC9536-10PC44I es adecuado para 6 aplicacións: Industrial Control Logic, Data Acquisition Interface, Legacy Peripheral Consolidation, Test and Measurement Equipment, Embedded System Interface Hub, Security and Access Control Logic.
Industrial Control Logic
The XC9536-10PC44I fits industrial control logic that requires deterministic propagation delay and nonvolatile configuration without the resource cost of a large FPGA. Its 10 ns maximum pin-to-pin delay, 36 macrocells, and 34 I/Os are suitable for combining discrete logic, machine-state controllers, interlocks, and discrete input conditioning on one board. The specified -40°C to +85°C industrial temperature range supports use in temperature-controlled factory equipment. In a controller, the device can implement registered state logic while its I/O pins connect sensors, actuator commands, status indicators, and safety interlocks. In-system programming permits configuration updates during test or maintenance, while the 800-gate-class architecture keeps the implementation compact.
Recomendado
Data Acquisition Interface
The XC9536-10PC44I can implement deterministic acquisition front-end logic between sensors, converters, memory, and a host processor. Its 36 macrocells and 34 I/Os provide enough connectivity for timing controls, channel multiplexing, trigger routing, data-valid qualification, and status flags, while the 10 ns delay supports short combinational timing paths. The device is especially useful when the acquisition interface must remain programmable but does not justify a large FPGA. In-system programming allows calibration tables, trigger profiles, or interface revisions to be stored in the same device and updated without board replacement. Timing analysis should verify acquisition setup and hold margins against the external converter and bus devices.
Recomendado
Legacy Peripheral Consolidation
The XC9536-10PC44I is useful for replacing combinations of discrete AND, OR, counter, decode, and glue-logic devices around a legacy processor or peripheral bus. With 36 product-term-oriented macrocells and approximately 800 usable gates, it can consolidate fixed control paths while retaining user-programmable flexibility. The 34 I/Os are suitable for address decoding, interrupt routing, bus arbitration, and chipset sequencing. Its nonvolatile Fast FLASH configuration preserves the implemented logic across power cycles, eliminating repetitive hardware programming. Migration should begin with a gate-level map and should verify signal polarity, timing, unused-pin behavior, and bus contention before removing the original logic.
Recomendado
Test and Measurement Equipment
The XC9536-10PC44I supports compact test and measurement control logic where predictable propagation delay and broad I/O connectivity are more important than very high logic density. It can implement sequencers, pattern generators, stimulus routing, binning logic, and instrument status control using its 36 macrocells and 10 ns maximum pin-to-pin delay. The -40°C to +85°C range covers many laboratory and industrial-instrument environments. In-system programming supports product-specific test sequences and calibration logic, while parallel programming of multiple XC9500 devices can simplify configuration of multi-board instruments. Engineers should account for test-fixture loading, grounded I/O behavior, and the exact acquisition timing when assigning external pins.
Recomendado
Embedded System Interface Hub
The XC9536-10PC44I can serve as a programmable interface hub between a host processor and mixed peripheral logic. Its 34 I/Os support chip selects, address decode, interrupt multiplexing, level translation control, reset sequencing, and status aggregation without requiring a full FPGA. The 10 ns timing class is suitable for many register-to-register and combinational control paths, while nonvolatile configuration provides rapid and repeatable startup behavior. Because this is a 5 V CPLD, interface design must verify every attached signal's voltage and input thresholds before using the device as a level shifter. Firmware developers can instead use the XC9536XL-10PC44I candidate when evaluating a modern family replacement.
Recomendado
Security and Access Control Logic
The XC9536-10PC44I can implement compact credential, lock, keypad, and alarm sequencing logic where nonvolatile configuration and deterministic response times are useful. Thirty-four I/Os allow integration of keypad scanning, indicator control, door-position inputs, relay-command decoding, and communication strobes, while the 36-macrocell capacity supports state machines and auxiliary protocol logic. The 10 ns pin-to-pin delay is short enough for many digital control paths but does not replace timing analysis for security-critical outputs. Designers should use fail-safe output defaults, validate debounce intervals, and isolate safety mechanisms from ordinary programmable logic where applicable. Obsolete-device sourcing should include traceability and counterfeit-risk controls.

Notas de diseño
Do not treat a matching PLCC-44 outline as proof of electrical equivalence. Before substituting a candidate, compare the complete pin table, supply-voltage limits, input thresholds, output-drive behavior, I/O count, macrocell resources, configuration interface, and programming file requirements. The verified data establishes the target as a 44-pin PLCC with 34 I/Os and a 10 ns speed grade, but it does not provide a complete pin-by-pin equivalence matrix for every alternative.
Use the 10 ns maximum pin-to-pin propagation delay as a timing constraint rather than a guaranteed delay for every path. Analyze external setup and hold requirements, registered-versus-combinational paths, I/O loading, and the timing of attached buses or converters. Do not assume that a faster 7 ns family variant is automatically interchangeable; faster edge rates can expose ringing, skew, and board-level signal-integrity issues that were previously hidden in the 10 ns design.
The target is a PLCC-44 J-lead surface-mount package, not a leadless QFN. Preserve the manufacturer footprint, solder-pad geometry, component orientation, and thermal pad or exposed area specified by the package drawing. Verify connector and via access around the J-leads before substituting another package variant. Because the supplied excerpts do not include a complete pin table, the final board release should reference the official XC9500 package drawing and pin-assignment table.
The verified records identify a 5 V CPLD family and a 5.5 V maximum supply for the target, but they do not provide complete current, power, or power-up sequencing limits. Decoupling and rail design must therefore follow the manufacturer recommended-application circuit rather than generic CPLD assumptions. Check every attached signal source for compatibility with the device's input thresholds, and include adequate bypass capacitance close to the supply and ground pins.
Información de cumplimiento
The supplied data identifies an industrial-grade device but does not provide RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations. AEC-Q100 is not applicable because the component is an industrial CPLD rather than an AEC-Q100-qualified automotive device.
