XC95108-7PC84C - 108-Macrocell 5V CPLD | Xilinx | Industrial Logic
부품 번호: XC95108-7PC84C ✗ 단종XC95108-7PC84C 개요
A CPLD is a programmable logic device that combines interconnected macrocells, nonvolatile configuration storage, and user-programmable I/O in a single integrated circuit. The XC9500 family sits within the broader hierarchy of programmable logic devices, alongside FPGAs and other CPLDs, and is intended for designs requiring deterministic logic implementation, in-system reconfiguration, and 5 V compatibility.
The XC95108 provides 108 macrocells with 2,400 usable gates according to the verified product listing. Its 69 I/O positions support mixed interface logic, while the -7 speed grade is identified by a 7.5 ns pin-to-pin delay and a maximum fCNT of 125 MHz. In-system programming supports at least 10,000 program or erase cycles, making the device useful where field updates or configuration changes are required.
Internally, the device uses advanced CMOS 5 V Fast FLASH technology, and multiple XC9500 devices can be programmed in parallel. This architecture retains configuration in nonvolatile memory, allowing the logic design to persist without a separate external configuration PROM. Parallel programming can shorten production or system-level programming time when several devices operate together.
Typical uses include industrial control logic, legacy peripheral interfacing, glue logic, data-routing networks, embedded sequencing, and board-level design consolidation. Its 69 available I/O pins are particularly useful when a design needs numerous control signals but does not justify a larger programmable-logic device. The 5 V environment also supports systems that retain legacy interface voltage requirements.
When planning a board, verify the PC84 footprint, programming signals, supply requirements, and I/O-standard compatibility against the manufacturer datasheet. Because this family uses a nonstandard 5 V architecture and a legacy PLCC-style package, verify availability, lifecycle status, and intended obsolescence-management plans before starting a new production design.
This page combines verified manufacturer and distributor information with package-level design guidance, application analysis, lifecycle cautions, and a focused review of same-footprint speed-grade alternatives. That synthesis helps engineers distinguish a genuine PCB-compatible choice from a merely similar CPLD before committing a legacy design to replacement.

일반적인 애플리케이션
XC95108-7PC84C 적합 용도: 6 애플리케이션s: Industrial Equipment Control Logic, Legacy Peripheral Interface Consolidation, Data Routing and Protocol Bridging, Board-Level Glue Logic, Test and Measurement Control, In-System Configurable Production Systems.
Industrial Equipment Control Logic
The XC95108-7PC84C is suitable for consolidating deterministic control, sequencing, and interlock logic in legacy industrial equipment. Its 108 macrocells and 2,400 usable gates provide capacity for state machines and interface decoding, while 69 user I/O pins support discrete sensors, actuator commands, and bus-control signals. The verified 7.5 ns pin-to-pin delay and 125 MHz maximum fCNT give designers useful timing headroom for ordinary control paths. Because the device carries an obsolete family status, engineers should preserve the footprint for maintenance but plan migration for new production platforms.
추천
Legacy Peripheral Interface Consolidation
The XC95108-7PC84C can combine address decoding, chip-select generation, interrupt handling, and data-routing functions around older peripherals. With 69 available user I/O pins, it addresses boards that need considerably more interface signals than a small CPLD while remaining below the resource level of a large FPGA. The 5 V architecture can simplify integration with legacy buses, although every external signal still requires voltage-level and drive-strength verification. Designers should use the AMD DS066 datasheet to review I/O behavior and timing constraints.
추천
Data Routing and Protocol Bridging
For data-routing networks, protocol conversion, and fixed-format packet handling, the XC95108’s 108 macrocells provide programmable combinational and sequential logic. The device can implement state machines, FIFO control, byte-lane selection, and error handling without relying on a processor for every simple transfer decision. Its verified 7.5 ns pin-to-pin delay supports timing designs operating below the 125 MHz fCNT ceiling, while 69 I/O pins expose multiple parallel channels. Final timing closure remains path- and I/O-dependent and should be checked against the actual speed grade.
추천
Board-Level Glue Logic
The XC95108-7PC84C is appropriate for glue logic that coordinates power sequencing, resets, configuration control, peripheral enables, and status aggregation. Such designs often require numerous discrete control outputs but modest arithmetic performance, making the 69 I/O count and 108 macrocells more relevant than raw gate count. The 5 V supply architecture supports integration with older system rails, and in-system programming permits field updates without relying on a separate configuration PROM. Because the device is obsolete, firmware and configuration-file retention should form part of a long-term maintenance plan.
추천
Test and Measurement Control
The XC95108-7PC84C can implement test sequencing, instrument-control state machines, trigger routing, and status decoding in legacy measurement equipment. Its 125 MHz maximum fCNT provides ample margin for ordinary control sequencing, while 69 I/O pins support parallel front-panel, fixture, and inter-instrument connections. The nonvolatile configuration is also useful where measurement settings or control sequences must survive power loss. Engineers must still confirm the commercial temperature rating, analog-interface requirements, and long-term component availability before supporting new test platforms.
추천
In-System Configurable Production Systems
The XC95108-7PC84C supports in-system programming with a verified minimum endurance of 10,000 program or erase cycles, making it useful in systems that receive logic updates during manufacturing or maintenance. Its Fast FLASH architecture retains configuration without an external PROM, and the family supports parallel programming of multiple devices. Those characteristics can simplify production fixtures that program several boards simultaneously and reduce field-update complexity. The development workflow should preserve the correct configuration file, programming voltage, timing setup, and device identification for every board revision.

주요 차별점
- Higher timing performance than the -10 speed grade (vs XC95108-10PC84C)
- Same-family resource and package continuity (vs XC95108-5PC84C)
- Distinct timing margin from the faster -5 grade (vs XC95108-5PC84C)
설계 노트
Treat the PC84 footprint as a legacy PLCC-style land pattern and compare it directly with the manufacturer package drawing before ordering a replacement PCB. The package code, terminal numbering, exposed geometry, and lead pitch must match the original assembly. Do not infer footprint equivalence from the common PC84 suffix alone, because manufacturing drawings and land-pattern tolerances are controlling. Prototype the socketed package and verify programming access before authorizing a large legacy-system build.
Do not treat a different XC95108 speed grade as automatically equivalent without checking the timing report and configuration constraints. The target is the -7 grade with a verified 7.5 ns pin-to-pin delay and 125 MHz maximum fCNT, while a -5 candidate is faster. Faster timing can alter external hold or setup margins, and a slower candidate can break critical paths. Revalidate the complete design in the selected timing simulation rather than relying on the family headline frequency.
Follow the AMD DS066 datasheet for supply pins, decoupling, programming voltage, and normal operating current because those values are not present in the verified web data supplied for this record. Place required bypass capacitors adjacent to the relevant supply pins and keep programming and normal-operation power sequencing within the manufacturer limits. The 5 V label describes the device architecture, but it is not sufficient evidence that every I/O or programming signal should be driven at 5 V.
Preserve the exact programming file, programming cable settings, device identifier, and board revision whenever an XC95108 is replaced. The verified family supports at least 10,000 program or erase cycles, but endurance does not eliminate configuration-file or bitstream-management risk. For maintenance programs, archive the tool version and verify the replacement reports the expected device and package before allowing field programming.
