XC9536XL-7PC44C - 36-Macrocell CPLD, 34 I/O | Xilinx
Teilenummer: XC9536XL-7PC44C ✗ AbgekündigtXC9536XL-7PC44C Übersicht
A complex programmable logic device, or CPLD, is a user-programmable semiconductor that combines a flexible logic architecture with nonvolatile configuration storage. CPLDs occupy the middle ground between simple programmable logic arrays and larger FPGAs. They are commonly used for glue logic, bus decoding, interface adaptation, state machines, address decoding, and control logic that benefits from fast deterministic routing and in-system reconfiguration.
The XC9536XL architecture provides 54V18 function blocks, 36 macrocells, and approximately 800 usable gates. Its 34 I/O pins support the integration of multiple control and data signals in a compact device. In-system programmability allows the configuration memory to be updated while the circuit remains operational, making the CPLD useful for field upgrades, production programming, and prototype refinement without replacing the device.
The XC9536XL-7PC44C uses 3.3 V CMOS technology and is specified in a 44-pin J-lead PLCC package with a square package code of QCCJ. Its 5 ns propagation-delay value provides deterministic behavior for control logic, while the 178.6 MHz speed rating supports clocked state machines and moderately timed interface functions. The commercial grade and 0.35 µm process place this device in a mature programmable-logic family.
Typical applications include industrial control interfaces, peripheral bus decoding, instrumentation logic, embedded-system address translation, data acquisition control, and legacy platform consolidation. The 34-I/O count makes the device especially suitable for designs that need more logic than a small GAL or simple microcontroller output can provide, without requiring a large FPGA.
PCB design should preserve the PLCC footprint and route programming and control signals away from high-speed or switching nodes. Use the manufacturer pin description table when assigning tracks, confirm decoupling requirements from DS058, and validate every external interface against the selected I/O standard. Because the device is lead-containing and RoHS non-compliant, its regulatory status must be considered for new commercial and export-sensitive designs.

Typische Anwendungen
XC9536XL-7PC44C ist geeignet für 6 Anwendungs: Industrial Address Decoding, Peripheral Bus Interface Control, Data Acquisition Control, Embedded System Glue Logic, Instrumentation Signal Conditioning, Legacy Platform Consolidation.
Industrial Address Decoding
The XC9536XL-7PC44C is well suited to industrial address decoding because its 36 macrocells and 34 user I/O pins can implement multiple decode equations and control outputs without relying on a large FPGA. Its 5 ns propagation delay provides short, predictable combinational paths, while the 3.3 V supply matches many legacy control boards. Place the CPLD close to the buses it decodes, route address and command signals away from switching nodes, and use DS058 to confirm every bank and I/O voltage assignment before layout release.
Empfohlen
Peripheral Bus Interface Control
The XC9536XL-7PC44C can implement state machines, chip-select generation, and protocol translation for a 3.3 V peripheral bus. Its 36 macrocells provide enough logic for multi-cycle sequencing, and in-system programming permits firmware or configuration revisions without replacing the device. The 44-pin PLCC footprint also supports repair and legacy-system consolidation. Designers should define bus ownership in the design tool, include contention-safe tri-state behavior, and validate propagation timing against the slowest participating peripheral.
Empfohlen
Data Acquisition Control
The XC9536XL-7PC44C fits acquisition systems that require deterministic sequencing between sensors, converters, and memory. Thirty-four I/O pins can distribute enables, selects, triggers, and status signals, while the 5 ns propagation delay supports tightly coordinated control functions. The commercial temperature grade suits controlled indoor equipment. Keep analog and high-impedance sensor paths separated from CPLD switching activity, follow the decoupling guidance in AMD DS058, and review timing for every acquisition trigger relationship.
Empfohlen
Embedded System Glue Logic
The XC9536XL-7PC44C is useful when a microcontroller or processor requires programmable glue logic for chip selects, reset sequencing, interrupt routing, or legacy signal translation. The 36-macrocell capacity provides more flexibility than simple fixed logic, while the 178.6 MHz device rating supports clocked control functions. The in-system-programmable architecture allows logic revisions during product maintenance. Keep firmware and CPLD configuration under separate revision control, define startup ownership clearly, and validate power-up states through the system timing budget.
Empfohlen
Instrumentation Signal Conditioning
The XC9536XL-7PC44C can implement control logic for instrumentation front ends, including range selection, measurement gating, status encoding, and relay-command sequencing. Its 36 macrocells and 34 I/O pins allow several instrument functions to be consolidated in one PLCC device. The 5 ns propagation delay helps maintain predictable sequencing between measurement channels. Use grounded return paths, isolate sensitive inputs from digital switching activity, and check supply tolerances and I/O thresholds against the instrument front end before production release.
Empfohlen
Legacy Platform Consolidation
The XC9536XL-7PC44C is appropriate for consolidating several PLDs or discrete glue-logic devices into one configurable CPLD. Thirty-four I/O pins and 800 usable gates provide meaningful capacity while retaining the 44-pin PLCC package used by established assemblies. In-system programming supports lifecycle updates and manufacturing flexibility. Before replacement, compare every terminal assignment, power pin, and I/O standard, then regenerate and statically time the design for the -7 speed grade rather than assuming logic interchangeability.

Designhinweise
Treat the PLCC footprint as a pin-sensitive interface rather than a generic 44-terminal grid. Follow the physical terminal-numbering drawing in AMD DS058, preserve pin-1 orientation, and avoid placing vias or tall components where they interfere with the socket or heatsink. Because the package has 34 user I/O pins, maintain consistent, short routing from the device to nearby passive and connector networks, while keeping programming and clock traces away from switching-power nodes.
Use the supply-decoupling network and operating limits defined in AMD DS058, including the specified voltage tolerance and capacitor characteristics. Place bulk and high-frequency decoupling close to the associated power terminals, with a low-impedance return path to the supply or ground plane. Estimate worst-case dissipation from supply voltage, device activity, and I/O loading, then verify that the PLCC and board construction remain within their intended commercial-temperature operating environment.
Do not treat the XC9536XL-5PC44C and XC9536XL-10PC44C as unconditional functional substitutes for the -7 device. Their timing grades differ from the target, so rerun static timing analysis and confirm external setup and hold requirements. The XC9536XL-7PC44I changes the environmental grade, and the XC9536XL-7PCG44C changes the lead-free ordering configuration. In every case, compare the exact terminal and electrical tables before releasing a replacement BOM.
Assign I/O standards only after checking the output and input thresholds required by every connected device. Avoid driving a shared bus from multiple configured outputs, and specify deterministic power-up states for shared-enable or reset signals. Keep sensitive measurement inputs away from the PLCC socket and programming interface, and use ground-plane continuity rather than long ground traces. A short, repeatable layout is especially important when restoring this legacy package in an existing industrial assembly.
Compliance-Informationen
The device is identified as containing lead and as RoHS non-compliant. No REACH, halogen-free, conflict-minerals, or automotive-qualification status is stated.
