XC9536-7PC44I 概要
A CPLD, or complex programmable logic device, is a user-programmable digital integrated circuit that combines a structured logic array with nonvolatile configuration memory. Within the programmable-logic hierarchy, the XC9536 belongs to the XC9500 5 V CPLD family: a configurable-logic device within the broader FPGA and CPLD category of programmable semiconductors. Its nonvolatile FLASH configuration allows the implemented logic to remain after power is removed, eliminating separate program-memory implementation.
Key features include 36 macrocells, two logic array blocks, approximately 800 programmable gates, and up to 34 I/O pins. The verified product information identifies 7.5 ns as the maximum propagation delay, while the family description reports 5 ns pin-to-pin logic delays on all pins and fCNT operation up to 125 MHz. The -7 speed designation, industrial temperature grade, and 5 V operating supply place the component in the performance and environmental class represented by XC9536-7PC44I.
The 44-pin PLCC package supports through-hole board assembly and socket-based prototyping. Partstack identifies package code QCCJ, square package shape, 44 terminals, and industrial temperature grading. The verified lifecycle listing identifies the device as obsolete, so new designs should assess current platform availability and consider a redesign when long-term production support is required.
Typical applications include industrial control interfaces, legacy bus and address decoding, alarm and sequencing logic, peripheral glue logic, and communication-control subsystems. The nonvolatile configuration and deterministic propagation performance are useful where control logic must restart without a separate programming cycle.
When replacing this part, verify the pinout, macrocell count, supply voltage, I/O standards, timing margin, and programming file compatibility. The package identifier alone does not establish equivalence between PLCC and PQFP variants. For new 5 V designs, verify whether the obsolete XC9500 architecture remains the correct long-term choice or whether a current CPLD/FPGA platform offers better lifecycle support.

主な用途
XC9536-7PC44I の用途: 6 件s: Industrial Control and Sequencing Logic, Legacy Interface and Address Decoding, Alarm and Fault-Response Logic, Communication Control Subsystem, Peripheral Glue and Timing Control, Instrumentation Signal Routing.
Industrial Control and Sequencing Logic
The XC9536-7PC44I fits legacy industrial control logic because it provides 36 macrocells, approximately 800 gates, 34 I/O pins, and deterministic 5 V operation. Its 7.5 ns maximum propagation delay and family capability up to 125 MHz are useful for implementing state machines, interlocks, sequencing, and discrete control functions. The industrial temperature grade also matches equipment expected to operate outside commercial-temperature limits. Because the device is obsolete, engineers should preserve the design for repair and lifecycle-extension use while considering an active CPLD for new machines.
おすすめ
Legacy Interface and Address Decoding
The XC9536-7PC44I is suitable for decoding legacy bus addresses and translating parallel interfaces when a design needs nonvolatile logic in a compact 44-pin PLCC package. Its 36 macrocells and 34 I/O pins provide capacity for address comparison, chip selects, arbitration, and status-bit conditioning. The verified 5 ns family pin-to-pin delay helps preserve edge timing margins, while the 7.5 ns maximum specification supplies a device-level timing check. Any replacement must preserve the exact I/O assignments and PLCC footprint rather than relying only on gate-count similarity.
おすすめ
Alarm and Fault-Response Logic
The XC9536-7PC44I can implement alarm evaluation, fault latching, warning prioritization, and shutdown sequencing in equipment-control boards. Its nonvolatile FLASH configuration preserves the implemented logic through power cycles, while 34 I/O pins allow it to monitor multiple sensors and drive discrete indicators. The 7 ns speed designation and 36 macrocells support compact combinational and registered logic. For safety-related machinery, engineers must also verify applicable reliability, diagnostic, and regulatory requirements that are not specified by the component listing.
おすすめ
Communication Control Subsystem
The XC9536-7PC44I is applicable to protocol front ends that require deterministic framing, command decoding, parity generation, or transceiver control. Its 34 I/O pins support parallel data, handshake, and status connections, while the family-level 5 ns pin-to-pin delay helps maintain timing margins around the programmable logic. The device does not itself provide a communications PHY, so it should be paired with an appropriate transceiver such as SN75176BD or a modern interface controller. Nonvolatile configuration also simplifies standalone control-node startup.
おすすめ
Peripheral Glue and Timing Control
The XC9536-7PC44I can consolidate repetitive peripheral glue logic around legacy processors, memory devices, and data converters. Its 36 macrocells are useful for data-width conversion, register shadowing, chip-select generation, and coordinated control outputs. The verified 125 MHz fCNT capability provides substantial timing headroom compared with many low-cost PLDs, although actual system margins depend on routing and external loads. During replacement, verify every pin, power-supply requirement, and configuration file because PLCC package similarity does not guarantee programming compatibility.
おすすめ
Instrumentation Signal Routing
The XC9536-7PC44I is suitable for instrument-control boards that route switch matrices, route measurement controls, and coordinate front-panel indicators. Its 34 I/O pins and 36 macrocells allow substantial fixed routing logic to be consolidated, while the industrial grade supports use in equipment environments. The 5 V supply matches many legacy analog and digital sections, reducing level-conversion complexity. Signal-integrity checks remain essential for sensitive analog boards, including grounding, input slew rate, and isolation between digital routing and measurement front ends.

設計ノート
Do not treat every XC9536-7 variant as a PCB drop-in replacement. The verified listing identifies XC9536-7PC44I as 44-pin PLCC, while XC9536-7VQ44I and XC9536-7VQG44I use 44-pin PQFP-style packages. The PLCC and PQFP land patterns, lead pitch, height, and assembly process differ. Confirm the exact package drawing and schematic before substitution; electrical similarity alone does not make the surface-mount variants drop-in replacements.
The XC9536-7PC44I belongs to a 5 V CPLD family, so preserve the original design's supply tolerances, decoupling strategy, and input thresholds. Place local high-frequency bypass capacitance close to the device's supply and ground pins, while following the manufacturer XC9500 layout guidance for the exact package. Do not infer a 3.3 V-compatible substitute from the XL family reference; the verified comparison identifies XC9536XL-10VQ44C as a 3.3 V device while the target operates at 5 V.
Before reusing this CPLD in a PLCC socket or board footprint, verify all 44 terminal assignments, programming pins, supply pins, and ground positions against the manufacturer package drawing. The supplied excerpts do not provide a complete numbered pinout, so signal-level reassignment cannot be validated safely. For a redesign, export the programmed design, check timing against the 7.5 ns maximum propagation specification, and reserve programming or configuration access where the original board requires it.
A 44-pin PLCC provides a larger thermal path than many small surface-mount logic packages, but the verified data does not include thermal resistance or maximum junction temperature for this ordering code. Evaluate the actual board copper, socket, airflow, and switching activity rather than assuming PLCC construction eliminates thermal concerns. For obsolete inventory, request lot-specific condition and traceability because solder condition, storage history, and prior reflow can affect long-term reliability.
コンプライアンス情報
The verified data identifies EAR99 classification and an obsolete lifecycle status but does not provide RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations.
