MPN: XC9572-15PC84I ✗ जीवन की समाप्तिXC9572-15PC84I अवलोकन
A CPLD is a programmable-logic semiconductor that combines programmable AND/OR-style logic structures with configuration memory and I/O resources. The XC9572 belongs to the XC9500 5 V CPLD family, positioned between fixed logic and larger FPGAs. Its role in an electronics hierarchy is programmable logic device → CPLD → semiconductor, while its applications commonly include legacy control, interface, decoding, and glue-logic functions.
Key features include Advanced CMOS 5 V Fast FLASH technology, in-system programming, parallel programming of multiple XC9500 devices, and fast pin-to-pin logic delays. According to the XC9500 family material, the family supports pin-to-pin delays as low as 5 ns and fCNT operation up to 125 MHz. These figures describe family capabilities; the XC9572-15PC84I carries the slower 15 ns grade designation.
The XC9572 architecture contains 72 macrocells and 1,600 usable gates. Its FLASH-based configuration memory retains the programmed logic after power is removed, allowing field configuration through the in-system programming interface. Compared with mask-programmed logic, this makes the device suitable for prototypes, production runs with small volume changes, and board-level control logic that must be revised without changing the PCB artwork.
Typical applications include industrial controller glue logic, peripheral interfacing, legacy bus decoding, data acquisition systems, embedded control, and general-purpose logic consolidation. The 84-pin PLCC package also supports socketed prototyping and repair workflows, while the industrial temperature grade supports equipment operating across the stated -40°C to +85°C ambient range.
Designers should verify signal timing against the 15 ns grade, preserve required power and ground connections, and follow the DS065 programming and test guidance. Because this legacy device has been discontinued by the manufacturer, long-lived production programs should include lifecycle risk review, controlled inventory planning, and an approved redesign path.
This page combines the manufacturer DS065 specification details, package and lifecycle information, verified alternatives, and practical design guidance. It is intended to help engineers determine compatibility, understand timing constraints, and plan a sensible replacement or redesign strategy for this discontinued programmable-logic device.

सामान्य अनुप्रयोग
XC9572-15PC84I के लिए उपयुक्त है 6 अनुप्रयोगs: Industrial Control and Automation, Legacy Peripheral Interfacing, Bus Address Decoding, Data Acquisition Front Ends, Instrumentation and Test Equipment, Embedded System Glue Logic.
Industrial Control and Automation
The XC9572-15PC84I fits legacy industrial controllers that require deterministic programmable logic beside a microcontroller or processor. Its 72 macrocells and 1,600 usable gates can consolidate decoding, sequencing, interlock, and interface functions that would otherwise occupy multiple fixed-logic devices. The industrial suffix supports an ambient range of -40°C to +85°C, while the 15 ns speed grade establishes the timing class for control paths. Keep clocked logic inside the device's specified operating limits, preserve the DS065 power and programming connections, and verify worst-case timing at the system operating temperature.
अनुशंसित
Legacy Peripheral Interfacing
The XC9572-15PC84I is useful for adapting processor buses, latching external data, decoding addresses, and implementing handshake logic in older equipment. Its 84-terminal package provides more I/O than a small programmable-logic device, while FLASH configuration permits logic changes without replacing the component or revising the PCB. The 15 ns grade must satisfy the shortest specified clock-to-output and path-to-path requirements after accounting for PCB delay. Validate signal direction, drive strength, input thresholds, and external pull-up or pull-down networks against the electrical tables in DS065 before release.
अनुशंसित
Bus Address Decoding
The XC9572-15PC84I can implement multi-address decode, chip-select generation, command qualification, and fault interlocking within 72 macrocells. This makes it appropriate for systems where a processor or microcontroller requires deterministic auxiliary control not available in its own firmware. The 5 ns family pin-to-pin capability provides margin for many combinational decode paths, but the selected 15 ns grade and the actual tool timing report determine the guaranteed limit. Review unused pins, ensure every power and ground terminal is connected, and include the device's test and programming requirements in the board-level test plan.
अनुशंसित
Data Acquisition Front Ends
The XC9572-15PC84I can coordinate sample sequencing, channel multiplexing, latch control, trigger qualification, and data-valid signaling in legacy data-acquisition equipment. Its programmable logic makes it useful when timing relationships are more complex than simple fixed gates but do not require an FPGA. The 72 macrocells constrain how many independent channels and control states can be implemented, so designers should reserve resources for the required state machine and I/O. Validate setup and hold margins against the 15 ns grade and follow the DS065 grounding and decoupling guidance for dependable switching behavior.
अनुशंसित
Instrumentation and Test Equipment
The XC9572-15PC84I can implement measurement sequencing, relay-control interlocks, mode selection, front-panel status logic, and self-test routines in instrumentation products. Its 84-terminal package accommodates moderate I/O requirements, and in-system programming supports board-level configuration and service diagnostics. Because the device is discontinued, design documentation should also capture the bitstream, programmer settings, pin assignment, and timing constraints so the product can be serviced after its original build phase. Confirm commercial or industrial temperature requirements and inspect each received lot for condition and traceability.
अनुशंसित
Embedded System Glue Logic
The XC9572-15PC84I can bridge processor peripherals, generate precise control strobes, arbitrate requests, and consolidate miscellaneous digital functions around an embedded controller. Its FLASH-based configuration retains the design through power cycles and enables last-minute logic updates during production or maintenance. Designers should treat the CPLD as a timed digital component rather than a general-purpose processor: use the 15 ns speed grade to constrain paths, reserve configuration and test pins, and avoid exceeding documented supply and I/O conditions. A future FPGA migration remains possible but generally requires footprint, pinout, and timing reassessment.

डिज़ाइन नोट्स
Do not treat the XC9500 family's best-case 5 ns pin-to-pin delay as the guaranteed timing of XC9572-15PC84I. The target carries the 15 ns speed grade, so constrain every timing path using the grade-specific timing report and board-level delay. Also verify the complete pin and programming interface in DS065 before assigning a package suffix equivalent. A shared 84-terminal count does not by itself prove that power, ground, configuration, test, and I/O functions are arranged identically.
Use the DS065 package drawing and pin table to place the PLCC footprint, and connect all supply and ground pins rather than relying on a subset of parallel pins. Follow the manufacturer's guidance for decoupling and grounding around the 5 V supply. For a socketed legacy design, inspect socket contacts and solder joints for oxidation because intermittent supply or programming connections can appear as nondeterministic configuration failures. Preserve access to configuration and test signals for production programming and diagnostics.
Assign each external signal to a compatible I/O according to the electrical tables, including input threshold, output drive, and any dedicated configuration or control function. Do not leave a dedicated pin floating unless the pin-description table explicitly identifies it as no-connect. Keep clock and high-speed paths short, use controlled-return geometry for longer routes, and avoid routing sensitive edges adjacent to programming or other fast switching nets. Validate the final interface with the actual external device and cable.
Because the manufacturer has discontinued the XC9572-15PC84I, production continuity depends on preserving a complete engineering record: exact ordering code, pin table, timing report, bitstream, programmer version, cable configuration, board revisions, and inspection criteria. Request lot and date-code traceability when sourcing remaining inventory. Do not silently substitute a commercial-temperature grade into an industrial product, and do not assume that a cross-family CPLD can replace the device without package, pin, logic-resource, and programming-interface changes.
