XC9536XL-7VQ44I - 36-Macrocell 3.3V CPLD | AMD
MPN： XC9536XL-7VQ44I ✓ 啟用中XC9536XL-7VQ44I 概覽
A CPLD is a programmable logic device that combines reconfigurable logic fabric with nonvolatile configuration memory. Within the product hierarchy, a CPLD is a programmable logic device, which is a type of semiconductor and digital logic IC. Unlike a fixed-function controller, the XC9536XL-7VQ44I can implement multiple digital functions in one device, including state machines, address decoding, interface logic, and control logic.
The device provides 36 macrocells and 34 I/O pins in a compact 44-pin VQFP package. Its architecture includes 54V18 function blocks providing 800 usable gates, while the -7 speed designation identifies the device's 7.5 ns propagation-delay class. In-system programming supports configuration over the device's programming interface, and IEEE Std 1149.1 JTAG boundary scan supports inspection and debugging during hardware development.
The XC9500XL architecture is intended for low-voltage operation and high-performance logic implementations. Its Flash-based configuration retains the programmed logic when power is removed, eliminating separate configuration-memory components. The I/O structure supports system integration at 3.3 V, with 5 V tolerant I/O capability described for this device family, allowing selected external signals to exceed the nominal core voltage under appropriate operating conditions.
Typical applications include communications equipment, computing systems, industrial control, peripheral glue logic, bus-interface decoding, and compact control subsystems. The 36-macrocell capacity is particularly useful for designs requiring several interacting state machines or glue functions without implementing a larger programmable-logic device. Its 44-pin VQFP package also supports conventional board-level assembly and inspection.
Designers should confirm pin assignments, voltage tolerances, programming requirements, and timing constraints against the manufacturer datasheet before layout release. Boundary-scan access is useful during bring-up, but production programming should use the documented device algorithm and supported programming hardware. Care is also required when combining 5 V tolerant inputs with 3.3 V outputs because voltage-tolerance conditions are not identical to output drive capability.
This page consolidates device specifications, verified source links, engineering alternatives, comparison parameters, and practical design guidance for engineers evaluating the AMD XC9536XL-7VQ44I for compact low-voltage programmable-logic designs.

典型應用
XC9536XL-7VQ44I 適用於 6 應用s: Communications Interface Logic, Industrial Control and Sequencing, Peripheral Bus Interface Logic, Low-Voltage Computing Support Logic, Programmable Glue and State Machines, JTAG-Assisted Board Debugging.
Communications Interface Logic
The AMD XC9536XL-7VQ44I fits compact communications-interface logic where 36 Flash-configured macrocells and 34 I/O pins provide enough capacity for protocol state machines, control sequencing, and bus-interface glue. Its 7.5 ns propagation-delay class supports short combinational paths, while in-system programming allows configuration and board-level updates without a separate programming fixture. The 44-pin VQFP format also keeps routing manageable in equipment where space is constrained. Designers should use the family timing tables to establish path budgets and confirm that external interface voltage levels fall within the documented I/O conditions.
推薦
Industrial Control and Sequencing
The XC9536XL-7VQ44I is useful for industrial control blocks that coordinate sensors, relays, actuators, and supervisory functions in one programmable device. Thirty-four I/O pins can support multiple digital channels, while 36 macrocells can implement counter, latch, decoder, and finite-state-machine functions without a microprocessor. Flash-based in-system programming supports repeatable field configuration, and JTAG boundary scan helps engineers inspect assembled boards during commissioning. The exact operating-temperature range must be confirmed for the selected ordering code before deployment in industrial equipment.
推薦
Peripheral Bus Interface Logic
A 36-macrocell CPLD can provide a practical bridge between a host bus and slower or differently timed peripherals. The AMD XC9536XL-7VQ44I can implement address decoding, write-cycle qualification, data latching, and arbitration in configurable Flash-based logic. Its 34 I/O pins offer substantial interface flexibility within a 44-pin VQFP package, and the 7.5 ns speed class helps minimize combinational delay in common control paths. Boundary-scan support is valuable when the bus interface includes many routed nets that require board-level troubleshooting.
推薦
Low-Voltage Computing Support Logic
The XC9536XL-7VQ44I is suitable for auxiliary logic surrounding a 3.3 V computing subsystem, particularly where fixed-function gates are insufficient but a large FPGA is unnecessary. Thirty-six macrocells can consolidate power sequencing, command parsing, status encoding, and peripheral selects. The device's low-voltage focus and configurable Flash architecture suit repeatable product configurations, while the 44-pin VQFP provides a practical option for established assembly methods. Designers should account for I/O direction, pull-state requirements, and available 3.3 V or 2.5 V output-drive capabilities when partitioning system functions.
推薦
Programmable Glue and State Machines
The AMD XC9536XL-7VQ44I is a natural fit for consolidating several small state machines, mode controllers, interlocks, and datapath-control functions into one device. Its 36 macrocells and 54V18 function blocks provide more logic capacity than a simple GAL or small CPLD, while the 7.5 ns class remains suitable for many control and decode paths. In-system programming enables production configuration through the board connector, and JTAG boundary scan provides visibility during validation. A logic-hierarchy review remains essential to ensure each design uses the available macrocell and I/O resources efficiently.
推薦
JTAG-Assisted Board Debugging
The XC9536XL-7VQ44I supports IEEE Std 1149.1 JTAG boundary scan, making it useful in systems where board bring-up requires inspection of numerous digital nets. The boundary-scan path can assist engineers in verifying component connections and isolating routing faults before final functional tests. The device also provides 34 I/O pins and 36 macrocells for implementing the surrounding logic, allowing debug support to coexist with the product function. The JTAG chain must be designed according to the family documentation, with correct series resistors, clocking, and shared-chain handling where applicable.

主要差異化特點
- Direct same-footprint family alternative with unchanged nominal speed class (對比XC9536XL-7VQG44I)
- Faster logic timing in the same physical footprint (對比XC9536XL-5VQ44C)
- FastFLASH family support for in-system programming (對比XC9536-7VQ44I)
設計說明
Assign the PCB footprint from the exact 44-pin VQFP ordering code and verify every pin against the manufacturer pin-description table. Keep JTAG, programming, configuration, power, and ground pins routed according to the family reference design. A mechanically similar 44-pin VQFP is not sufficient evidence of electrical equivalence; check VQFP pin numbering, exposed pad treatment where applicable, and the meaning of every power and configuration connection before fabrication.
Design the 3.3 V supply path for both normal operation and in-system programming activity. Follow the datasheet requirements for input capacitance, supply sequencing, and local decoupling, placing the required ceramic capacitors close to their associated supply pins. The 5 V tolerant I/O designation does not mean every pin can continuously drive 5 V or that all outputs have identical drive capability, so separate input-tolerance rules from output-voltage rules when designing mixed-voltage interfaces.
Use the manufacturer's timing tables to establish input, output, and clock-path budgets for the 7.5 ns speed class. Include external trace delay, connector loading, and any clock fan-out in the system-level timing check. For JTAG boundary scan, follow the documented chain and termination arrangement so the debug interface does not add unstable loading to sensitive control nets. Series-resistor values and clock-routing topology should follow the applicable reference design rather than a generic rule.
Do not treat a suffix change as electrically neutral without review. The XC9536XL-7VQG44I shares the family and footprint, while the -5VQ44C and -5VQG44C parts use a faster 5 ns class, and XC9536-7VQ44I belongs to the earlier XC9500 family. Check lifecycle, qualification, temperature, configuration-file compatibility, programming algorithm, and pin descriptions before substituting any candidate. Preserve the original part number in manufacturing documentation until validation is complete.
