XC9536-10VQ44C - 36-Macrocell 5ns CPLD | Xilinx | FPGA
部品番号: XC9536-10VQ44C ✗ 生産終了XC9536-10VQ44C 概要
A CPLD, or complex programmable logic device, is a user-programmable semiconductor positioned between fixed-function logic and larger FPGAs. Its nonvolatile configuration memory retains the programmed logic after power is removed, while its macrocell architecture implements combinational and registered Boolean functions in a compact package. The XC9500 family provides a practical bridge for designs that need more flexibility than a PAL or conventional gate array but do not require the resource density or configuration flexibility of a large FPGA.
Key features of the XC9536-10VQ44C include 36 macrocells, 800 usable gates, 34 user I/O pins, 5 ns pin-to-pin logic delay, 5 V operation, and in-system programmability. The verified data also identifies support for parallel programming of multiple XC9500 devices, which can simplify production programming or board-level update procedures. The device is specified as a commercial-grade component in distributor data.
The XC9536 architecture is organized around two function blocks, providing the stated 36 macrocell implementation and approximately 800 usable gates. Its nonvolatile Fast FLASH configuration allows logic to remain resident without a separate configuration PROM. For designs requiring more logic density, the related XC9500XL family supports pin-compatible migration across multiple density options in suitable package footprints, subject to careful verification of device-specific characteristics.
Typical applications include industrial control and automation, peripheral interface control, data acquisition systems, communications equipment, embedded instrumentation, and legacy system refresh projects. The 34 available I/O pins allow the CPLD to combine address decoding, handshake generation, latch control, status logic, and protocol translation in one device. The 5 ns delay supports moderate-speed control paths where deterministic logic behavior is more important than high I/O throughput.
Designers should verify the exact pinout, power-supply requirements, I/O voltage limits, configuration interface, and timing constraints against the manufacturer datasheet before layout. A 44-pin surface-mount footprint also requires careful land-pattern and thermal assessment. Because the verified sources identify the device as obsolete in one distributor listing, long-term production planning should confirm availability and consider a documented migration path.
This product page consolidates verified distributor specifications, package information, lifecycle indications, pricing availability, and drop-in replacement research for engineers evaluating the XC9536-10VQ44C.

主な用途
XC9536-10VQ44C の用途: 6 件s: Industrial Control and Automation, Peripheral Interface and Bus Bridging, Data Acquisition Front Ends, Communication Equipment Control, Embedded Instrumentation, Legacy System Refresh.
Industrial Control and Automation
The XC9536-10VQ44C fits centralized machine-control logic because its 36 macrocells and 800 usable gates can implement interlocks, sequencing, alarm handling, and actuator-command logic while preserving the established 5 ns timing class. The 34 user I/O pins provide useful density for connecting discrete sensors, relay drivers, and status indicators without requiring a large FPGA. A designer would normally place the CPLD between a processor or controller and discrete I/O, using the original configuration for address decoding and handshake signals. Before production use, verify the exact temperature grade, supply tolerances, I/O limits, and obsolete-part availability against the manufacturer datasheet.
おすすめ
Peripheral Interface and Bus Bridging
The XC9536-10VQ44C is suitable for protocol translation and legacy peripheral interfacing because 34 user I/O pins can divide among address decoding, data qualification, interrupt request generation, and bus control. Its 5 ns pin-to-pin delay supports general control logic rather than very high-speed synchronous memory interfaces. In a typical bridge, the CPLD would translate a processor interface into a narrower or wider peripheral protocol and register selected status signals. Because the verified material does not provide the full pinout or I/O electrical tables, engineers should confirm every connected signal and voltage domain in the manufacturer datasheet before routing or upgrading the design.
おすすめ
Data Acquisition Front Ends
The XC9536 can front-end an acquisition system by performing channel selection, trigger qualification, sample sequencing, and data-ready signaling ahead of a processor. The 36-macrocell, 800-usable-gate implementation provides enough logic for moderate control paths, while 34 I/O pins support trigger, status, and multiplexing functions. Its verified 5 ns delay class can support deterministic handshakes when external timing permits. A practical implementation would pair the CPLD with an ADC front end and use the CPLD to generate deterministic sample controls. Validate setup time, hold time, clock quality, and any I/O voltage limitations from the original datasheet rather than deriving them from the distributor summary.
おすすめ
Communication Equipment Control
The XC9536-10VQ44C can handle framing, flow control, and status decoding in communication equipment where a small deterministic control engine is preferable to a large FPGA. Its 34 user I/O pins accommodate serial-enable, carrier-detect, reset, timing, and alarm signals, while the 800 usable gates support moderate protocol state machines. The CPLD would normally sit beside a network or serial transceiver and coordinate reset, muxing, and interrupt pathways. The verified maximum-frequency context of 100 MHz indicates general control suitability, but it does not replace timing analysis of external interfaces. Firmware or configuration equivalence must also be established when moving from the original XC9500 device to XC9500XL.
おすすめ
Embedded Instrumentation
The XC9536-10VQ44C fits embedded instrumentation designs that require deterministic panel, measurement, and storage-control logic. Its 36 macrocells can combine mode selection, measurement sequencing, display enables, and fault latches, while 34 I/O pins provide flexible connections to sensors and control boards. The 5 ns delay and 100 MHz frequency context are appropriate for control and status paths that are not dominated by high-rate streaming. In such a system, the CPLD may coordinate a microcontroller with display, memory, and interface logic. Verify the commercial temperature grade against the instrument enclosure environment and use the original manufacturer documentation for timing, power, and pin-level constraints.
おすすめ
Legacy System Refresh
The XC9536-10VQ44C is relevant to legacy-system refresh projects that need to preserve an existing 44-VQFP board while consolidating several PAL, GAL, or small CPLD sections into one nonvolatile programmable device. With 36 macrocells and 800 usable gates, it can implement address decode, latch control, and auxiliary state logic, reducing component count without changing the footprint. The nonvolatile Fast FLASH architecture retains configuration after power removal and supports at least 10,000 program/erase cycles. For an existing PCB, engineers should still compare the complete pin map, configuration pins, supply requirements, and I/O standards. The related XC9536XL-10VQ44C is a documented pin-compatible migration path within the XL family, but its architecture and timing require explicit validation.

主な差別化要因
- Original XC9500 architecture with established 5 ns timing （vs XC9536XL-10VQ44C)

- Closest verified ordering-code alternative （vs XC9536-10VQG44C)
設計ノート
Use the exact 44-VQFP manufacturer land pattern rather than a generic TQFP footprint. The verified package is 44-VQFP at 10 mm x 10 mm, and even small differences in pad length, span, or exposed thermal features can affect solderability. Because the supplied excerpts do not include the complete pin map or package drawing, cross-check every pin number against the manufacturer datasheet before releasing artwork.
Treat the 5 V supply and every I/O rail as separate design constraints. The verified data identifies the device as a 5 V Fast FLASH CPLD, but it does not provide the complete DC supply ranges, input thresholds, output drive limits, or I/O voltage combinations. Review the original electrical-characteristics table and maintain adequate bypass routing before considering this device equivalent to a modern low-voltage CPLD.
Do not assume that the XC9536XL-10VQ44C is an unconditional drop-in replacement merely because the XC9500XL documentation describes pin compatibility within the family. The XL device uses a different family architecture, and the verified excerpts do not establish identical timing, configuration, voltage, or I/O behavior. Complete a device-by-device comparison, re-run timing constraints, and confirm that the existing configuration can be migrated.
Preserve access to the configuration and programming interface when laying out the board. Although the exact pins are not present in the supplied data, the device is specifically identified as in-system programmable and supports parallel programming of multiple XC9500 devices. Keep programming-chain routing away from sensitive signals, provide dependable reference connections, and consult the manufacturer programming and test guidance before fixing the footprint.
