Артикул: XC9572-7PC84C ✓ АктивенXC9572-7PC84C Обзор
A CPLD is a programmable logic device that sits between fixed-function logic and an FPGA in the broader semiconductor hierarchy. Its nonvolatile architecture retains a programmed logic configuration after power removal, while its macrocell structure and in-system programming interface support practical field configuration, testing, and design migration. The XC9572 belongs to the XC9500 5 V CPLD family and uses Advanced CMOS 5V Fast FLASH technology.
Key features include 72 macrocells, 1,600 usable gates, 7.5 ns pin-to-pin delay, operation to 125 MHz, 5 V in-system programming, and a stated programming endurance of at least 10,000 program or erase cycles. The family also supports parallel programming of multiple XC9500 devices. These characteristics make the XC9572 appropriate for consolidating medium-complexity control logic, interface decoding, state machines, and legacy glue logic.
The XC9572-7PC84C is identified as a commercial-grade 84-terminal J-bend device in an 84-lead LCC package. The -7 speed designation corresponds to the verified 7.5 ns pin-to-pin delay, while the C suffix denotes the commercial ordering variant. Because this is a 5 V architecture, system designers must verify every attached signal against the device's input thresholds and supply requirements rather than treating it as a modern 3.3 V or 1.8 V CPLD.
Typical applications include industrial control systems, legacy peripheral interfaces, programmable logic replacement, instrumentation, and compact control boards requiring nonvolatile logic with in-system reconfiguration. It is especially relevant where a small amount of moderate logic must be consolidated without moving the design to a larger FPGA. Its 84-lead PLCC footprint also supports migration among compatible XC9500 devices when macrocell count, timing, and pin assignment remain acceptable.
The principal design consideration is compatibility with the original XC9500 implementation. Engineers should preserve the target's power architecture, verify every pin against the XC9572 package data, and confirm that the design meets the 7.5 ns timing requirement. The XC9572 is identified as RoHS non-compliant and contains lead, so new regulated production designs should require an explicit lifecycle and environmental review before procurement.
This page consolidates verified manufacturer and distributor information, drop-in same-family options, parameter comparisons, and practical migration guidance. The alternatives and application passages are intentionally limited to package-compatible XC9500-family choices supported by the supplied evidence, avoiding unrelated FPGA replacements that would require redesign.

Типичное применение
XC9572-7PC84C подходит для 6 применениеs: Legacy Peripheral Interface Consolidation, Programmable Logic Replacement, Industrial Control and Automation, Instrumentation Signal Routing, Embedded Control Glue Logic, Board-Level Test and Manufacturing.
Legacy Peripheral Interface Consolidation
The XC9572-7PC84C is well suited to consolidating medium-complexity peripheral logic around legacy processors. Its 72 macrocells and 1,600 usable gates provide capacity for address decoding, command sequencing, interrupt arbitration, and state-machine control without requiring a larger FPGA. The verified 7.5 ns pin-to-pin delay and 125 MHz fCNT capability offer useful timing margin for conventional control paths. Because the device supports 5 V in-system programming and nonvolatile Flash configuration, it can also simplify laboratory bring-up and board-level repair workflows. Engineers should still verify each interface signal voltage and the complete 84-pin assignment against the official DS065 package data before layout reuse.

Programmable Logic Replacement
The XC9572-7PC84C can replace multiple conventional PAL, GAL, or discrete gate-logic sections when the required function fits within 72 macrocells and 1,600 usable gates. Its nonvolatile Advanced CMOS 5V Fast FLASH architecture retains the configuration after power removal, while in-system programming supports updates without removing the device. The 84-lead PLCC package provides 84 terminals and is suitable for legacy-style board revisions that already use that footprint. Migration should begin with a pin-level comparison and timing review because a compatible family name alone does not prove that every power, control, or I/O assignment is electrically identical.
Рекомендуется
Industrial Control and Automation
The XC9572-7PC84C can implement deterministic sequencing, interlocks, sensor logic, and actuator-command decoding in industrial control equipment when the system uses a compatible 5 V environment. Its 7.5 ns pin-to-pin delay and 125 MHz fCNT rating support high-speed control logic, while 72 macrocells allow several related functions to be consolidated. The device is identified as commercial grade, so the exact operating-temperature envelope must be confirmed from the manufacturer datasheet before deployment in a factory environment subject to temperature extremes. In-system programming also permits controlled firmware updates, but production procedures should include configuration checks and recovery procedures appropriate for field-serviceable equipment.
Рекомендуется
Instrumentation Signal Routing
The XC9572-7PC84C is useful in instrumentation systems for configurable routing, trigger decoding, mode control, and measurement-sequence logic. Its 72 macrocells provide enough capacity to combine multiple control functions, and the 7.5 ns pin-to-pin delay can support precise coordination between acquisition and communication subsystems. The device's Flash-based nonvolatile configuration allows a stored instrument personality to load at power-up, while in-system programming simplifies configuration updates during calibration or engineering evaluation. Signal-integrity work remains essential: engineers should keep sensitive analog paths away from programming activity, apply appropriate grounding, and verify every 5 V interface level against the input thresholds stated in the official datasheet.
Рекомендуется
Embedded Control Glue Logic
The XC9572-7PC84C can add nonvolatile glue logic around a microprocessor or microcontroller without expanding the main processor's pin budget. Typical functions include bus decoding, interrupt capture, watchdog sequencing, reset coordination, and peripheral-chip enables. With 72 macrocells and 1,600 usable gates, the device can consolidate logic that would otherwise occupy several programmable-logic packages. Its 125 MHz fCNT capability may be valuable when coordinating communication and real-time control functions, although final timing closure must use the actual macrocell path. The 84-lead PLCC footprint also permits targeted reuse of older control-board layouts, subject to full pin and electrical compatibility checks.
Рекомендуется
Board-Level Test and Manufacturing
The XC9572-7PC84C supports manufacturing workflows that benefit from in-system configuration and built-in test access. Its 5 V in-system programming interface can allow the same production board to be programmed, tested, and reprogrammed without removing the device, reducing fixture complexity. The XC9500 family's support for parallel programming of multiple devices is particularly relevant to multi-board or multi-device assemblies, provided the board design and programming fixture implement the required interface correctly. A production procedure should include blank-pattern detection, configuration verification, and post-program functional tests. Engineers should also account for the device's 10,000-cycle minimum program or erase endurance when repeated test or field-reconfiguration patterns are expected.

Заметки по проектированию
Do not substitute a family member solely because its macrocell count and speed designation appear similar. Confirm the exact package drawing, power pins, programming interface, I/O standards, and every assigned pin against DS065. The XC9572-10PCG84C and XC9572-15PCG84C references in the cross-reference search are not included as drop-in alternatives because their 10 ns and 15 ns delay classes differ from the target's 7.5 ns class by more than the permitted parameter-proximity threshold.
Design the board around a stable 5 V supply and verify the XC9572's input and output thresholds before attaching external signals. Because the verified data does not state operating-voltage tolerances or current limits, these values must be obtained from the official datasheet rather than inferred. Keep programming and logic-supply paths short, provide local bulk and bypass capacitance according to the manufacturer guidance, and avoid allowing disabled or unused pins to impose unintended loading on surrounding circuitry.
Preserve the original XC9572-7PC84C land pattern and component orientation when reusing an 84-lead PLCC board. The verified data confirms an 84-terminal J-bend package but does not provide a complete pin map, so board changes should be validated against the official package drawing and pin table. Maintain sensible separation between programming signals, clocked logic, and sensitive analog routing, and review unused pins according to the datasheet because their required states are not available in the supplied excerpts.
The device is verified as RoHS non-compliant and contains lead. Do not release a new regulated-production design without a documented environmental and lifecycle review. For legacy maintenance, distinguish a genuine original or qualified stocked component from an unverified substitute, obtain manufacturer traceability where possible, and inspect the exact package markings. The supplied data does not provide authorized-distributor stock quantities or numeric prices, so procurement decisions require a live quote as of 2026-10-28.
