XC9536XV-5VQ44C - 5ns 2.5V CPLD, 44-TQFP | AMD
Référence : XC9536XV-5VQ44C ✓ ActifXC9536XV-5VQ44C Présentation
A CPLD is a programmable logic device that combines multiple programmable logic blocks with a deterministic interconnect structure. It occupies the hierarchy above basic programmable logic arrays but below field-programmable gate arrays, providing fixed in-system reconfiguration capability for glue logic, control logic, bus decoding, interface adaptation, and compact state-machine implementation. FastFLASH technology supports convenient configuration and reprogramming, while in-system programmability allows logic updates without removing the device from its circuit.
The XC9536XV family provides 800 usable gates across two 54V18 function blocks. Its -5 speed designation corresponds to a 5 ns maximum pin-to-pin logic delay, making it suitable for communications, computing, and embedded control paths with defined timing requirements. The internal core voltage range is 2.37 V to 2.62 V. The device also supports multiple I/O voltage operation, allowing interface compatibility with surrounding system logic when the applicable voltage combinations are observed.
The 44-pin package provides 34 usable I/O in the cited configuration and a surface-mount form factor suitable for automated assembly. Programmable functions are divided between two 54V18 blocks, enabling medium-density combinational and sequential logic without the resource overhead of a large FPGA. The architecture is particularly useful for deterministic control paths, peripheral interfacing, data-format conversion, and compact protocol handling where reusability and in-system programming are important.
Typical uses include communications interface logic, embedded computing control, bus arbitration, peripheral bridging, and low-latency state-machine implementations. In each case, the device consolidates several small logic functions into one programmable component, reduces discrete gate count, and allows firmware-linked design revisions. A designer can also use the XC9572XV family member when additional logic capacity is needed while retaining the same package and voltage-oriented family platform.
Designers should verify the complete pin description, supported I/O standards, configuration pins, and electrical constraints in the manufacturer datasheet before layout release. The package drawing and pin numbering must match the 44-TQFP footprint, while power and ground distribution should follow the datasheet recommendations for reliable signal integrity and predictable device operation.

Applications typiques
XC9536XV-5VQ44C convient pour 6 applications: Communications Interface Logic, Embedded Computing Control, Bus Interfacing and Data Conversion, Industrial Control and State Machines, Peripheral Configuration and Glue Logic, Low-Voltage Embedded Systems.
Communications Interface Logic
The AMD XC9536XV-5VQ44C fits communications equipment that requires compact, reprogrammable logic for protocol adaptation, signal conditioning, command decoding, or control-plane functions. Its two 54V18 function blocks provide 800 usable gates and 34 I/O, while the 5 ns maximum pin-to-pin delay supports timing paths that are substantially faster than general-purpose low-density PLDs. In-system programmability lets engineers update constants, interface behavior, or control sequences without changing the PCB when the logic configuration evolves. The 44-TQFP package also supports standard surface-mount assembly. Final design review should verify applicable I/O voltage combinations, configuration timing, and worst-case system timing against the manufacturer datasheet.

Embedded Computing Control
XC9536XV-5VQ44C is appropriate for embedded computing systems that need dedicated control logic alongside a host processor. Typical tasks include bus arbitration, address decoding, interrupt coordination, peripheral selection, and data-format conversion. The CPLD offloads fixed hardware functions from the processor, reducing software overhead and providing deterministic behavior for control operations. Its 800 usable gates are sufficient for a focused set of combinational and sequential functions, while in-system programmability supports product revisions. The 5 ns speed grade can simplify synchronous control paths. Engineers should budget available macrocell resources carefully and check all supply, ground, configuration, and I/O constraints in the datasheet before release.

Bus Interfacing and Data Conversion
The AMD XC9536XV-5VQ44C can serve as a compact interface between logic domains requiring different bus widths, byte ordering, framing, or timing conventions. Two 54V18 function blocks and 34 I/O provide enough resources for small interface translators, while the 5 ns pin-to-pin delay supports many short combinational paths. FastFLASH technology and in-system programmability allow bus-mapping logic to be revised during development or product maintenance. Because a CPLD has fixed architecture and finite interconnect resources, designers should avoid treating it as an unrestricted FPGA substitute. Confirm pin multiplexing, bank voltage limits, initialization behavior, and maximum operating frequency in the datasheet before finalizing the interface.

Industrial Control and State Machines
The XC9536XV-5VQ44C is well suited to compact industrial control modules that coordinate sensors, relays, counters, sequencers, and safety interlocks through deterministic logic. The -5 speed grade provides a 5 ns maximum pin-to-pin delay, allowing the CPLD to handle short control paths with predictable timing. Its 800 usable gates and 72 macrocells are useful for consolidating multiple small state machines into one programmable device. In-system programmability simplifies maintenance because operating sequences can be updated without board replacement when the electrical environment permits reconfiguration. The commercial 0 °C to 70 °C rating should be checked against the actual enclosure temperature, while industrial temperature and qualification requirements should be resolved before deployment.
Recommandé
Peripheral Configuration and Glue Logic
XC9536XV-5VQ44C can consolidate peripheral configuration registers, chip-select logic, level conversion within supported voltage conditions, and timing glue that would otherwise occupy multiple discrete components. Its 44-TQFP package offers 34 I/O in the cited configuration and is suitable for compact controller boards. FastFLASH technology and in-system programmability simplify field updates, while the two function blocks provide a straightforward architecture for moderate logic density. A practical design should reserve pins for configuration behavior and verify the selected startup mode against the board's power sequence. Engineers should also validate propagation delays across every combinational path and ensure the programmed state matches the hardware requirements during power-up and reset.
Recommandé
Low-Voltage Embedded Systems
The XC9536XV-5VQ44C fits low-voltage embedded systems whose internal core operates within the specified 2.37 V to 2.62 V range. It can implement local sequencing, power-state coordination, sensor-control logic, or peripheral bridging where a microcontroller would otherwise require several support gates. The multi-voltage capability supports systems with more than one logic voltage, but each I/O assignment must be checked against the applicable power bank and external driver limits. The 5 ns speed class provides useful timing margin for short control paths. Designers should define the startup sequence, validate configuration pins, and calculate worst-case timing using the device's actual operating temperature and supply voltage rather than relying only on the nominal speed designation.

Notes de conception
Use the 44-TQFP land pattern and pin numbering from the manufacturer package drawing rather than relying on the generic VQ44 marking. Place decoupling capacitors close to the device's supply and ground pins, route configuration pins according to the selected startup mode, and preserve the required copper and solder-mask geometry specified for the package. Check every assigned I/O against its applicable power-supply domain before routing.
Build timing closure from the actual logic path rather than the 5 ns headline delay alone. The 5 ns value is a maximum pin-to-pin propagation specification, and a complete path may include interconnect, macrocell, and external component delays. Identify all synchronous and asynchronous paths, apply the appropriate clock and setup constraints, and verify operation across the intended 2.37 V to 2.62 V core range.
Do not substitute an alternative solely because it has a VQ44 package or a similar XC9500XV family name. XC9572XV-5VQ44C doubles macrocell capacity, XC9536XV-7VQ44C uses a slower timing grade, and XC9536XL-10VQG44C belongs to a 3.3 V platform. Review configuration pins, startup behavior, I/O voltage limits, resource use, and timing before approving any replacement.
The target is a 2.5 V CPLD with an internal supply range of 2.37 V to 2.62 V, but the external I/O voltage options must be checked independently in the datasheet. Design the power tree so core and I/O domains meet their permitted combinations. Confirm supply sequencing, configuration behavior during power transitions, and the amount of external logic sharing each output rail.
Informations de conformité
No definitive RoHS, REACH, lead-free, halogen-free, or conflict-minerals declarations were identified for this exact ordering code. The CPLD is a commercial-temperature 0 °C to 70 °C component rather than an automotive-qualified device.
