XC9536XL-7VQ64I - 36-Macrocell 3.3V CPLD | AMD Xilinx
部品番号: XC9536XL-7VQ64I ✗ 生産終了XC9536XL-7VQ64I 概要
A complex programmable logic device, or CPLD, belongs to the programmable-logic hierarchy alongside FPGA technology. Unlike mask-programmed fixed logic, a CPLD retains its programmed configuration in nonvolatile memory. The XC9536XL family combines macrocell-based logic with user I/O resources, making it useful for consolidating control logic, decoding, state machines, bus interface logic, and fixed-format glue functions into a relatively small device.
The principal device attributes include 36 macrocells, 36 I/O pins, 3.3 V operation, 5 ns propagation delay, and 800 usable gates. Its I/O arrangement is intended for 3.3 V systems, while associated family information also identifies 5 V tolerant inputs and 2.5 V output capability. At least 10,000 program and erase cycles are specified for the in-system programmable configuration memory, allowing repeated field updates when the design, configuration data, or board behavior changes.
The XC9536XL uses a macrocell-centered architecture in which each macrocell contributes combinational and registered logic resources. This structure gives the device deterministic programmable logic rather than the block-routing architecture of an FPGA. The XC9536XL-7 speed designation corresponds to the 5 ns performance grade identified for this family, making it more appropriate for timing-sensitive control paths than the slower -10 grade. The 0.35 µm CMOS implementation is a legacy process technology associated with the original XC9500XL generation.
Typical uses include industrial control, instrumentation, power-system sequencing, peripheral interfacing, data acquisition, and legacy equipment upgrades. It is particularly useful when a board already contains a programmed XC9500XL design and needs another density or speed grade that remains mechanically and electrically compatible. The 64-pin package also supports designs needing more I/O than the smaller family members while avoiding a larger package.
Design planning should verify the exact pin assignments, power rails, configuration pins, and I/O voltage assumptions in the manufacturer datasheet before layout release. Because this legacy family was created for 0.35 µm CMOS designs, software support and programming-cable compatibility can determine whether an unchanged architecture remains practical for a new production run.
This product analysis combines the device architecture, programming characteristics, package information, timing grade, and directly comparable same-family options into an engineering-focused guide. It also distinguishes true package-compatible replacements from larger XC9500XL devices that require different footprints, helping designers avoid a replacement that changes the PCB rather than merely changing a bill-of-materials line.

主な用途
XC9536XL-7VQ64I の用途: 6 件s: Industrial Control Logic, Data Acquisition Interface, Power-System Sequencing, Legacy Peripheral Interface, Communication Interface Conditioning, Instrumentation and Test Control.
Industrial Control Logic
The XC9536XL-7VQ64I is suitable for consolidating sequencing, interlocks, alarm logic, and discrete control functions into a compact programmable-logic device. Its 36 macrocells provide 800 usable gates, while the 5 ns pin-to-pin propagation delay supports deterministic control paths. The 36 user I/O pins allow direct connections to sensors, relay drivers, status indicators, and operator interfaces without an external microcontroller. For a new board, the designer must still define pull-ups, input thresholds, and output drive details from the manufacturer pin and electrical tables. The in-system programming capability supports configuration updates during production test or field maintenance, provided the legacy programming environment and connector remain usable.
おすすめ
Data Acquisition Interface
The XC9536XL-7VQ64I can implement address decoding, data capture control, strobe generation, and interface arbitration between an acquisition circuit and a host processor. Its 36 I/O pins are useful when the board needs several parallel data, chip-select, and handshake lines rather than a small number of discrete gates. The 5 ns grade helps preserve short combinational delays in acquisition control paths, although the complete timing budget must include external peripheral delays. During schematic design, assign unused pins deliberately and confirm whether they are regular user I/O, configuration inputs, or dedicated control functions. In-system programming permits board-level configuration and test-sequence changes without relying on a mask-programmed device.
おすすめ
Power-System Sequencing
The XC9536XL-7VQ64I can implement ordered rail enable, power-good qualification, timeout, and fault-latching logic for a multi-rail industrial or instrument system. Thirty-six macrocells are adequate for combining multiple sequencing channels with status registers and deterministic control outputs, while 5 ns propagation delay helps keep enable relationships tightly controlled. The design should define fail-safe states for every supply-enable output and specify behavior during configuration, reset, and loss of control. Because this is a programmable logic device rather than a dedicated power sequencer, verify output voltage tolerances, transition behavior, and input thresholds against the manufacturer electrical characteristics.
おすすめ
Legacy Peripheral Interface
The XC9536XL-7VQ64I is appropriate for adapting legacy parallel peripherals to a modern control system through address decoding, bus arbitration, interrupt generation, and level conversion control. Its macrocell architecture offers predictable logic implementation, and its 36 I/O pins provide enough connectivity for an 8- or 16-bit data path plus associated control signals. A drop-in timing-grade substitution can preserve the PCB when the alternative satisfies the original temperature, qualification, and timing constraints. Before replacing the device, verify signal direction in the pin table and validate that the alternative retains the same configuration and I/O behavior rather than assuming that a shared package guarantees functional equivalence.
おすすめ
Communication Interface Conditioning
The XC9536XL-7VQ64I can implement command parsing, framing, checksum generation, modem-control signaling, and interrupt logic around serial or parallel communication interfaces. The 800 usable gates allow a complete protocol state machine and supporting registers to share one device, while the 5 ns grade supports short internal timing paths. The designer must account for protocol timing outside the CPLD, including cable, transceiver, and clock delays. The package provides a compact footprint for legacy communication boards, but modern production programs should confirm that configuration files, programmer support, and test coverage remain available. Where isolation is required, keep the programmable logic outside the high-voltage domain and interface through suitable isolation components.
おすすめ
Instrumentation and Test Control
The XC9536XL-7VQ64I is useful in legacy instrumentation for switch-control timing, measurement sequencing, front-panel status, and test-point multiplexing. Its 36 macrocells and 36 I/O pins can implement several channels of deterministic control without requiring a large FPGA. The 5 ns propagation delay is valuable for short timing chains, but analog settling, relay delay, and instrument handshake time must be included in the complete timing budget. In-system programming simplifies board configuration during test, although the programming fixture should retain a defined state on every configuration and power-control pin. For production continuation, validate the programmer, cable, and software workflow before committing the legacy design to new production.

設計ノート
Do not treat every XC9500XL-family member as a drop-in replacement. The XC9572XL, XC95108XL, and XC95144XL increase the macrocell or I/O count, and their package requirements can differ from the 64-pin target. Keep the physical PCB fixed only when the selected alternative uses the same 64-pin VTQFP land pattern, the same pin functions, the same 3.3 V supply arrangement, and acceptable timing and qualification limits.
Reserve the configuration pins and programming interface according to the manufacturer pin-description table before committing to the board layout. Keep programming access reachable for production test and field maintenance, and define a safe state for configuration control lines during reset or power sequencing. Because the target is a legacy CPLD, verify pin direction, input-level tolerance, and output-drive details against the exact ordering code rather than relying on a generic XC9500XL schematic.
Treat the 5 ns propagation delay as only one part of the interface timing budget. Add external transceiver, connector, routing, and clock-path delays before choosing the -5, -7, or -10 grade. When substituting a slower -10 device, rerun static timing for every clock domain and I/O constraint. A shared package does not remove the need to confirm setup, hold, skew, and output-loading requirements.
Design the 3.3 V rail for the device's specified operating current and the board's I/O loading rather than for logic quiescent current alone. Place bulk and local decoupling close to the supply pins, maintain the required return path, and separate switching supplies from sensitive signal paths where practical. Validate every external signal voltage against the family's stated input and output levels, including any 5 V tolerant input assumptions.
