A CPLD, or complex programmable logic device, is a programmable logic device organized into interconnected macrocells and programmable interconnect resources. In the broader semiconductor hierarchy, a CPLD sits between basic programmable logic devices and FPGAs: it provides deterministic timing, nonvolatile configuration, and a relatively compact architecture for consolidating glue logic, control functions, state machines, and interface conditioning. The XC9536 family offers 800 usable gates, 36 macrocells, and an fCNT specification of 125 MHz according to the manufacturer datasheet material supplied for this part.
Key features include 5 ns pin-to-pin logic delays on all pins, 34 I/O pins, and in-system programmability for at least 10,000 program/erase cycles. Its nonvolatile FastFLASH configuration supports repeatable field updates without relying on an external configuration memory. The XC9536 is useful when a design requires more deterministic structure than a small single-chip PLD while remaining less complex than an FPGA implementation.
The two function-block architecture provides 36 macrocells and 800 usable gates, with programmable interconnect supporting general-purpose logic integration. Its 125 MHz fCNT value makes the device suitable for control logic, interface adaptation, address decoding, and low-to-moderate-speed digital state-machine designs. Exact I/O standards, current limits, and recommended operating conditions should be confirmed in the complete manufacturer datasheet before production release.
Typical applications include industrial control logic, legacy peripheral emulation, data-acquisition interface conditioning, and programmable test fixtures. Because the device is a nonvolatile 5 V CPLD, it is particularly useful where power-up behavior, deterministic propagation delay, and in-system reconfiguration matter more than the very high logic density of an FPGA.
When laying out the PCB, preserve the manufacturer's recommended power and ground distribution, place programming interface access for production and field updates, and validate every connected I/O against the device's absolute maximum and recommended conditions. The supplied material indicates that this variant contains lead and is RoHS non-compliant, so it may not suit new designs subject to restricted-substance requirements.
This page consolidates the supplied manufacturer and distributor information, identifies strict same-package drop-in candidates, and adds engineering-focused comparison and design guidance that is not normally presented together on a distributor listing.

典型應用
XC9536-5VQ44C 適用於 6 應用s: Industrial Control Logic, Data-Acquisition Interface Conditioning, Programmable Test Fixture, Legacy Peripheral Emulation, Communication Interface Control, Programmable Sensor Hub.
Industrial Control Logic
The XC9536-5VQ44C fits compact industrial control blocks that combine state-machine logic, command decoding, interlocks, and peripheral interface conditioning. Its 36 macrocells, 800 usable gates, and 5 ns pin-to-pin delay provide useful deterministic timing without requiring an FPGA. The 125 MHz fCNT specification supports higher-speed control logic, while nonvolatile in-system programming permits field updates without a separate configuration loader. For production, verify the industrial temperature suffix, supply tolerances, and I/O limits in the full datasheet.
推薦
Data-Acquisition Interface Conditioning
The XC9536-5VQ44C can consolidate acquisition-board logic such as channel selection, timing sequencing, handshake generation, status decoding, and test-signal routing. Thirty-four I/O pins provide more interface capacity than a minimal PLD, while the 5 ns pin-to-pin delay and 125 MHz fCNT figure suit deterministic control paths. Nonvolatile FastFLASH configuration also allows repeatable in-system updates. Signal-level compatibility with the ADC, sensors, and isolation devices must be checked against the complete electrical tables before implementation.
推薦
Programmable Test Fixture
The XC9536-5VQ44C is well suited to fixture controllers that route test points, control relays and instrument handshakes, and apply repeatable I/O patterns to the unit under test. Its 36 macrocells and 800 usable gates support moderate sequencing logic, and in-system programming permits fixture behavior to be updated for different boards. The 5 ns path delay helps constrain timing relationships, although fixture rise times, relay isolation, and ground-loop behavior remain external to the CPLD and require separate engineering.
推薦
Legacy Peripheral Emulation
The XC9536-5VQ44C can reproduce glue logic formerly implemented with multiple PALs, TTL chips, or one-off gate arrays. Its 36 macrocells and 34 I/O pins offer enough resources for bus decode, register emulation, interrupt sequencing, and protocol translation. The 5 ns pin-to-pin delay provides predictable timing for legacy buses, while nonvolatile configuration removes the need for an external startup PROM. Replace existing TTL signals only after accounting for voltage levels, rise times, fan-out, and open-collector behavior.
推薦
Communication Interface Control
The XC9536-5VQ44C can serve as the central glue device around communication transceivers, implementing byte framing, parity checks, timeout counters, flow-control logic, and command parsing. Thirty-four I/O pins suit parallel data and control paths, and the 125 MHz fCNT rating provides margin for common serial-to-parallel interface rates. Its in-system programmability helps adapt controllers across product revisions. Nevertheless, the CPLD does not replace transceiver electrical design, impedance control, isolation, or protocol-specific timing constraints.
推薦
Programmable Sensor Hub
The XC9536-5VQ44C can coordinate multiple sensors by handling selection strobes, data-ready signals, threshold flags, sampling counters, and alarm-routing logic. Its compact 44-pin VQFP package helps control board area, while 36 macrocells and 34 I/O pins provide practical connectivity for a modest sensor network. The 5 ns logic delay and 125 MHz fCNT figure support tightly sequenced digital operations. Sensor analog bandwidth, supply noise, and environmental range remain separate design constraints and require verification.

主要差異化特點
- Provides a documented 5 ns pin-to-pin logic delay for general-purpose 5 V CPLD designs (對比XC9536XL-5VQ44C)
- Commercial-grade ordering code preserves the original XC9536 device identity (對比XC9536-5VQ44I)
- Active original-family offering avoids selecting a documented obsolete variant (對比XC9536-5VQG44C)
- Matches the resource density of the target without doubling macrocell count (對比XC9572XV-5VQ44C)
設計說明
Treat the XC9500 5 V family power architecture as the basis for decoupling and rail planning, but confirm the exact recommended capacitor values and allowable supply tolerance in the complete datasheet. Place the bulk capacitor near the supply entry and local high-frequency decoupling close to the device's VCC pins. Avoid routing programming or high-current outputs beside sensitive input returns, because simultaneous switching can disturb the 5 V rail and corrupt marginal interface timing.
Preserve the manufacturer's VQFP-44 footprint, pad dimensions, and thermal-via recommendations rather than deriving them from the generic package name. Inspect the assembly drawing for pin-1 orientation and verify every programmed pin against the design's VHDL or Verilog constraints. Leave programming access reachable for production and field updates, and include a recovery path because in-system programming does not eliminate the need for a valid configuration image.
The verified 5 ns pin-to-pin delay describes device propagation delay, not the complete channel delay of external circuitry. Budget external rise time, connector loading, fan-out, and possible contention before relying on a system timing budget. Use current-limited outputs and appropriate termination where a connected bus can be reconfigured, especially in fixtures or shared legacy backplanes where two programmed devices may briefly drive the same net during startup.
Do not substitute another XC9536 suffix solely because the package is VQFP-44. Check the supply-voltage family, temperature grade, macrocell count, I/O standards, programming interface, and power-up behavior. In particular, XC9572XV-5VQ44C has 72 macrocells rather than 36, while XC9536-5VQG44C is identified as obsolete in the supplied comparison. Validate the exact replacement with an unrevised schematic, equivalent timing simulation, and a board-level bring-up test.
合規資訊
The verified XC9536-5VQ44C specification reports RoHS Non-Compliant and Contains Lead. No verified data was provided for REACH, AEC-Q100, halogen-free status, or conflict-minerals compliance.
