XC9536-15VQ44I - 36-Macrocell 5V CPLD | AMD/Xilinx
Référence : XC9536-15VQ44I ✓ ActifXC9536-15VQ44I Présentation
A complex programmable logic device is a user-programmable digital semiconductor that stores its configuration in nonvolatile memory and implements combinational or registered logic after power-up. In the product hierarchy, a CPLD sits between individual logic gates and larger FPGAs: it provides more structured interconnect, macrocell-based logic, and predictable timing for compact control, interface, and glue-logic designs.
The XC9500 architecture uses eight 36V18 function blocks to provide 36 macrocells and approximately 800 usable gates. The -15 speed designation corresponds to a 15.0 ns maximum propagation-delay class, while the broader XC9500 family supports applications up to 125 MHz and includes 5 ns pin-to-pin logic on faster members. In-system programmability permits configuration updates through the device itself without removing it from its circuit board.
The device operates from a 4.5 V to 5.5 V internal supply range and provides 34 I/O in a surface-mount TQFP package. Its industrial-grade designation supports use in demanding control equipment, but the exact operating-temperature limits, I/O voltage range, absolute maximum ratings, and AC timing values should be checked in the manufacturer datasheet before release. Parallel programming of multiple XC9500 devices is supported by the family architecture.
Typical uses include industrial machine controls, legacy peripheral interfaces, data acquisition logic, and embedded control systems where a small quantity of deterministic combinational and sequential logic is required. In these applications, the 36 available macrocells can implement address decoding, state machines, interface translation, latches, counters, and glue logic around microprocessors or memory devices.
PCB implementation requires care around the 44-pin package, programming interface, power rails, and unused pins. Confirm every signal assignment against the pin-description table, preserve the required supply decoupling arrangement, and account for programming-mode access before routing the board. The XC9536-15VQ44I is best suited to new 5 V designs that specifically require its 36-macrocell capacity and 15 ns timing grade.
This product guide combines the device's architectural ratings, package information, programming characteristics, application guidance, and qualified same-family alternatives to support design selection and board planning. It also highlights the timing and temperature distinctions engineers should verify before treating related XC9536 variants as interchangeable.

Applications typiques
XC9536-15VQ44I convient pour 6 applications: Industrial Machine Control, Embedded Peripheral Interface Control, Data Acquisition Signal Conditioning, Communication Protocol Conversion, Test and Measurement Control Logic, Embedded System Power Sequencing.
Industrial Machine Control
The XC9536-15VQ44I is well suited to machine-control logic that combines deterministic state machines with I/O decoding around a microprocessor. Its 36 macrocells and eight 36V18 function blocks can divide logic resources among counter stages, interlocks, alarm latches, and motor-command decoding, while the 15.0 ns propagation-delay class defines the timing envelope for those paths. The 4.5 V to 5.5 V internal supply range supports conventional 5 V control electronics. Engineers should use the manufacturer pin and timing tables to allocate pins, establish clock-domain boundaries, and verify reset behavior before releasing the board for industrial deployment.
Recommandé
Embedded Peripheral Interface Control
The XC9536-15VQ44I can provide compact glue logic for decoding legacy peripheral addresses, generating enables and handshakes, or translating asynchronous control signals into a processor-friendly interface. Its 800 usable gates provide enough capacity for multiple small state machines and latch groups, while the 34 available I/O support connections to external buses and control signals. A 15.0 ns maximum propagation-delay class is suitable when the attached bus timing permits the selected I/O timing mode. The final design must verify setup and hold requirements, pin sharing, and whether the intended interface requires registered outputs or a particular programmable polarity.
Recommandé
Data Acquisition Signal Conditioning
For data-acquisition equipment, the XC9536-15VQ44I can implement trigger routing, channel selection, sample sequencing, status encoding, and front-panel control logic. Its 36 macrocells allow registered pipelines and combinational decode functions to coexist, while FLASH configuration provides deterministic operation immediately after power-up without a separate configuration PROM. The device's 5 V supply range suits systems built around 5 V sensors and converters, although the input thresholds, output drive, and noise performance of each I/O must be checked against the acquisition signal levels. Timing closure should include acquisition strobe delays and any external ADC or DAC control requirements.
Recommandé
Communication Protocol Conversion
The XC9536-15VQ44I can bridge dissimilar digital interfaces by translating parallel bus signals into command sequences or protocol framing. Eight 36V18 function blocks provide a practical partition for transmit and receive state machines, byte assembly, parity generation, and handshaking, while 34 I/O offer connections for data, control, and status signals. The 15 ns timing grade should be checked against the protocol's setup, hold, and clock-period requirements rather than selected from bandwidth alone. Because the architecture is Flash-based, interface behavior is retained across power cycles and can be updated in system when field reconfiguration is permitted by the product safety plan.
Recommandé
Test and Measurement Control Logic
The XC9536-15VQ44I can organize instrument control logic for front-panel selection, relay sequencing, range control, status indicators, and test-sequence coordination. The 36-macrocell capacity is appropriate for several small controllers without requiring the resource allocation of a large FPGA, while nonvolatile FLASH configuration makes the instrument's boot behavior predictable. The 5 V internal supply aligns with many legacy measurement boards, but every input still requires verification against its voltage threshold and output against its load. Engineers should reserve programming access, validate power-up states, and confirm that the 15.0 ns timing class meets instrument settling and handshake requirements.
Recommandé
Embedded System Power Sequencing
The XC9536-15VQ44I can generate reset sequencing, power-enable controls, interlock signals, and fault-latching functions around larger embedded processors. Its 36 macrocells are sufficient for sequencing several rails or managing ordered peripheral resets, and its in-system programming allows controlled updates during production or maintenance. The 4.5 V to 5.5 V supply requirement must be coordinated with upstream power rails so the CPLD begins operating only after its input voltage is valid. Designers should confirm I/O drive strength, pull-up or pull-down requirements, power-on reset behavior, and timing margins between the CPLD outputs and every controlled device's specified initialization interval.

Notes de conception
Assign the programming interface, clock, reset, and user I/O directly from the manufacturer pin-description table before laying out the 44-pin TQFP. Keep programming-access traces short and away from sensitive analog or high-speed nets. The 44-terminal footprint contains dedicated configuration and supply-related pins in addition to the 34 user I/O, so a schematic-level count of only 34 signals will not account for the complete package.
Do not substitute related XC9536 markings solely because the macrocell count and package look alike. Check the speed suffix, package suffix, temperature grade, pin assignments, supply range, and programming mode. The -6 and -10 variants have lower nominal maximum propagation delays than the -15 device, while variants carrying different suffix letters may differ in environmental or assembly-related attributes. Capture the approved manufacturer ordering code in the BOM to prevent accidental substitution.
Design the 5 V supply path for the device's full 4.5 V to 5.5 V internal operating range and place the required bypass capacitors close to the supply and ground pins. Verify sequencing against downstream circuits so the CPLD does not drive inputs before its supply is valid. During timing analysis, use the 15.0 ns maximum propagation-delay rating for XC9536-15VQ44I rather than the faster 5 ns or 6 ns ratings associated with other XC9500-family speed grades.
FLASH configuration makes the device operational immediately after power-up, so undefined or unintended programmed states can become system-level behavior rather than temporary startup symptoms. Define reset state, unused-pin treatment, and power-up outputs in the design. Also account for the minimum 10,000 program/erase-cycle capability when deciding whether field updates are appropriate, and validate every update procedure against the device's supported programming modes and supply requirements.
