XC9536-10PC44C - 800-Gate 5 ns CPLD | AMD | 44-Pin PLCC
MPN: XC9536-10PC44C ✓ ActiveXC9536-10PC44C Overview
A CPLD is a programmable logic device that combines multiple programmable logic blocks with a fixed internal interconnect structure. Within the broader semiconductor hierarchy, the XC9536 is a complex programmable logic device, a member of the XC9500 family of FLASH PLDs, and a complement to FPGA and microcontroller solutions. Its nonvolatile configuration allows the implemented control, decoding, interface, or glue-logic functions to remain after power is removed without an external configuration memory.
Key features include advanced CMOS 5 V Fast FLASH technology, support for parallel programming of multiple XC9500 devices, 34 I/O lines, and a maximum clock frequency of 66.7 MHz. The -10 speed grade identifies a 10 ns class of device, while the published family information describes 5 ns pin-to-pin logic delays. The 44-terminal commercial package provides a practical upgrade path for designs that need more I/O than smaller PLCC packages can offer.
The XC9536 architecture is appropriate for deterministic logic that must be programmed and updated as a production-line or field-programmable step. Unlike a soft-core microcontroller implementation, its logic is configured directly in hardware, which can reduce firmware overhead for decoding, glue logic, control sequencing, and fixed-format interfaces. The published 0.5 µm CMOS process information identifies the device as a mature FLASH CPLD rather than a modern FPGA architecture.
Typical applications include industrial control and factory automation, peripheral interface logic, legacy bus decoding, power sequencing, display and communication control, and embedded system support functions. The 5 V supply and 5 V I/O context make it especially relevant to legacy equipment where a modern low-voltage FPGA would require level-shifting or a different board revision.
When designing a replacement, verify the package pinout, supported I/O voltage, timing constraints, and power architecture rather than relying only on the XC9536 family name. The verified data does not expose a complete 44-pin net assignment, so the package drawing should be checked against the manufacturer datasheet before PCB changes or cross-family substitutions are approved. This page also consolidates verified specifications, same-family alternatives, pricing context, and practical design cautions.
The XC9536-10PC44C is best understood as a compact, nonvolatile, 5 V logic integration device. Its 36 macrocells, 34 I/O lines, 66.7 MHz maximum clock frequency, and 44-pin PLCC package make it suitable for moderate-complexity control and interface functions where a small FPGA would be unnecessary and a microcontroller would add firmware overhead.

Typical Applications
XC9536-10PC44C is suitable for 6 applications: Industrial Control and Automation Logic, Legacy Bus Decoding and Interface Control, Power Sequencing and System Control, Peripheral Glue Logic for Embedded Systems, Data Acquisition Front-End Control, Communication Interface Consolidation.
Industrial Control and Automation Logic
The XC9536-10PC44C fits fixed industrial control functions that require more logic than a basic PLD but do not justify a larger FPGA. Its 36 macrocells, eight 36V18 function blocks, and 34 I/O lines can implement sequencing, interlocks, command decoding, and peripheral-control logic. The 66.7 MHz maximum clock frequency supports moderate control-clock rates, while nonvolatile in-system FLASH configuration allows the same hardware platform to be updated during manufacturing or maintenance. Because the verified operating range is 0 °C to 70 °C, it is appropriate for indoor commercial-grade industrial equipment rather than harsh uncontrolled environments.
Recommended
Legacy Bus Decoding and Interface Control
XC9536-10PC44C is appropriate for decoding legacy bus addresses, generating enables and chip selects, and implementing protocol state machines in equipment that still uses 5 V interface logic. Thirty-four I/O lines provide enough board-level signals for address decoding, data qualification, interrupts, and control outputs without requiring external glue logic. Its 5 ns pin-to-pin delay class and 66.7 MHz maximum clock frequency can accommodate moderate peripheral transactions. The advantage is deterministic hardware behavior with nonvolatile configuration, although the exact I/O timing and pin assignment must be checked against the manufacturer datasheet before schematic sign-off.
Recommended
Power Sequencing and System Control
The XC9536-10PC44C can implement deterministic power-up sequencing, rail-enable generation, reset coordination, and fault-status logic around a larger control system. Its 36 macrocells and 34 I/O lines allow multiple sequencing channels and monitoring points to be combined in one nonvolatile programmable device. The 5 V operating context is useful in legacy systems whose supply rails and logic levels are already established, while the 66.7 MHz maximum clock frequency is ample for sequencing that is normally much slower. Designers should use the datasheet to confirm power-up behavior and I/O tolerances rather than infer them from the family summary.
Recommended
Peripheral Glue Logic for Embedded Systems
XC9536-10PC44C is useful when a microcontroller or processor board still requires flexible hardware glue for address decoding, interrupt routing, display multiplexing, or external control signals. The CPLD can hold its configuration in nonvolatile FLASH, avoiding an application-specific boot sequence for relatively fixed logic, while still allowing in-system programming when the product configuration changes. Thirty-four I/O lines and 36 macrocells provide more capacity than a simple GAL or PAL device. This arrangement can shorten development time compared with expanding a microcontroller pin budget, provided timing, 5 V signal levels, and board area are acceptable.
Recommended
Data Acquisition Front-End Control
The XC9536-10PC44C can coordinate multiplexers, sample-control signals, status flags, and interface enables in a 5 V data-acquisition front end. Its 34 I/O lines and 36 macrocells allow fixed timing and routing logic to be consolidated without introducing a soft processor solely for control sequencing. The 66.7 MHz maximum clock frequency is adequate for many control and data-strobe functions, but the device is not positioned as a high-speed signal-processing engine. Engineers should partition analog acquisition channels from digital control logic and verify acquisition-device timing margins against the selected CPLD speed grade.
Recommended
Communication Interface Consolidation
XC9536-10PC44C is applicable to compact communication equipment requiring 5 V-compatible command decoding, modem-control signaling, routing logic, or timing supervision. The nonvolatile FLASH architecture permits different interface configurations to be programmed during production without changing the PCB, and 34 I/O lines support several control and data signals in parallel. A 66.7 MHz maximum clock frequency can support moderate serial framing and packet-control tasks. For new 3.3 V or low-voltage systems, however, an XC9536XL or a modern low-voltage CPLD may be more appropriate; the verified XC9536XL comparison confirms a different 3.3 V electrical context.

Key Differentiators
- Exact same-family 10 ns grade with a 44-pin plastic LCC footprint (vs XC9536-7PC44C)
- Higher timing margin in the same XC9536 PC44 package (vs XC9536-5PC44C)
- Broader environmental positioning when the temperature rating is required (vs XC9536-7PC44C)
Design Notes
Do not treat the -10 ordering code and a 5 ns family timing statement as interchangeable specifications. The -10 suffix identifies the target's 10 ns speed grade, while the verified family material also describes 5 ns pin-to-pin logic delays. Build the timing constraints from the exact ordering code and the manufacturer datasheet. A replacement with a faster grade must still use the same pinout, voltage, configuration method, and valid timing constraints.
The XC9536-10PC44C uses a 44-pin plastic LCC footprint with J-bend leads. Preserve the component orientation, socket orientation, and pin-1 marking, and provide adequate clearance around the package for soldering, inspection, and rework. Although the verified data identifies package code QCCJ, it does not provide the complete land pattern or terminal net list; obtain both from the manufacturer datasheet rather than scaling a generic PLCC drawing.
The verified data establishes a 5 V supply context but does not provide detailed I/O current, quiescent-current, or power-down limits. Validate those values in the exact XC9536 datasheet before distributing the rails or calculating regulator headroom. Because dynamic power in a CMOS CPLD depends on logic activity and switching frequency, use measured or conservative activity assumptions rather than treating the published 66.7 MHz maximum frequency as a continuous operating condition.
Keep clock and high-fanout control routing short and avoid routing sensitive 5 V interfaces through long paths next to programming or switching circuitry. The XC9500 architecture supports in-system programming, so follow the manufacturer's programming-pin, enable, and power-up guidelines exactly. If the board replaces the target with a faster XC9536 speed grade, preserve the original configuration scheme and verify that external timing margins remain valid rather than changing pin placement or net topology.
Compliance Information
The supplied verified data does not state RoHS, REACH, lead-free, halogen-free, conflict-minerals, or automotive qualification status. AEC-Q100 is not applicable because this is a commercial-temperature programmable logic device rather than an automotive-qualified part.
