XC95108-7PC84I - 108-Macrocell 5V CPLD | AMD
N.º da peça: XC95108-7PC84I ✗ Fim de vidaXC95108-7PC84I Visão geral
A CPLD, or complex programmable logic device, is a programmable semiconductor that combines multiple logic functions into one configurable integrated circuit. In the product hierarchy, a CPLD is a programmable logic device, a form of FPGA-related semiconductor, and a member of the broader integrated-circuit and digital-logic categories. Unlike a software-defined processor, its combinational and sequential logic behavior is established by a configuration file that remains stored in the device's FLASH memory.
Key features include 108 macrocells, approximately 2,400 usable gates, 5 V operation, a 0.5 µm process, and 7.5 ns propagation delays stated in the AMD DS066 datasheet. The XC9500 family supports pin-to-pin logic delays down to 5 ns and operating frequencies up to 125 MHz across its available devices and speed grades. In-system programming and test capabilities allow configuration operations without removing the device from its assembled circuit.
The XC95108 architecture divides its logic capacity into eight 36V18 function blocks. Each function block contains 18 macrocells, allowing combinational logic and registered sequential functions to be distributed across the device. This structure gives the CPLD more predictable timing than a general-purpose FPGA and makes the XC9500 architecture useful for compact glue-logic, bus-control, address-decoding, state-machine, and peripheral-interface designs.
Typical applications include industrial control systems, legacy peripheral expansion, bus arbitration, data acquisition interfaces, embedded equipment, and general-purpose logic integration. The industrial-temperature suffix identifies the XC95108-7PC84I as an industrial-grade option, while its PLCC-84 package supports through-hole PCB assembly and conventional sockets. Designs must still account for the device's 5 V supply requirement and the electrical limits associated with the legacy XC9500 family.
The primary design consideration is migration planning. Before replacing this CPLD with another device, engineers should compare package geometry, supply voltage, I/O standards, configuration method, macrocell resource mapping, pin assignments, and timing constraints. Similar pinouts do not necessarily guarantee that an alternative can reuse the original JEDEC configuration file without recompilation or board changes.
This product record combines the verified AMD DS066 device description, distributor identifiers, and package details with practical migration guidance. It also distinguishes true same-footprint upgrade options from unrelated programmable-logic devices, helping engineers evaluate replacement risk without treating package similarity alone as proof of drop-in compatibility.

Aplicações típicas
XC95108-7PC84I é adequado para 6 aplicaçãos: Industrial Control and Automation, Legacy Peripheral Bus Interfacing, Data Acquisition Interface Control, Bus Arbitration and Address Decoding, Embedded Equipment Control Logic, Equipment Test and Boundary Control.
Industrial Control and Automation
The XC95108-7PC84I fits legacy industrial-control boards that require deterministic programmable logic beside a microcontroller. Its 108 macrocells and approximately 2,400 usable gates can implement state machines, interlocks, alarm logic, and interface decoding without occupying a large FPGA. The documented 7.5 ns propagation delay and 83.3 MHz operating point support timing-sensitive control paths. Using the 84-pin PLCC package also preserves compatibility with through-hole industrial assemblies. The primary qualification is the 5 V supply requirement and the need to confirm I/O levels against every connected controller and field-bus device.
Recomendado
Legacy Peripheral Bus Interfacing
The XC95108 is useful for adapting legacy peripheral buses and processor interfaces that are not directly supported by the host controller. Eight 36V18 function blocks provide 108 configurable macrocells for address decoding, arbitration, latch control, and data-path conditioning. The 7.5 ns propagation delay is materially shorter than the 15 ns and 20 ns family alternatives, preserving more timing margin in synchronous control logic. Because the exact user-I/O count and electrical characteristics were not reproduced in the supplied excerpts, a board-level review of the AMD DS066 pin and timing tables remains mandatory before deployment.
Recomendado
Data Acquisition Interface Control
The XC95108-7PC84I can implement deterministic acquisition-control logic for sampling triggers, channel selection, data valid signaling, and test sequencing. Its approximately 2,400 usable gates and 108 macrocells are sufficient for multiple fixed-format interface functions, while the 5 V architecture aligns with many legacy acquisition cards. The 7.5 ns delay and 83.3 MHz maximum frequency should be compared with converter settling times, data-clock periods, and external round-trip delay. Engineers must also confirm whether the acquisition front end uses 5 V, 3.3 V, or mixed-level interfaces before assigning CPLD pins.
Recomendado
Bus Arbitration and Address Decoding
Address decoding, bus arbitration, interrupt routing, and cycle-control logic are typical CPLD tasks, and the XC95108 provides 108 macrocells in a compact PLCC-84 package for those functions. Its eight 36V18 function blocks allow logic to be distributed without allocating a much larger programmable-logic device. The 7.5 ns propagation-delay specification gives designers substantially more margin than the 15 ns XC95108-15PC84I or 20 ns XC95108-20PC84C alternatives. The board design must nevertheless preserve the original I/O assignments and configuration unless the replacement device has been recompiled and timing-closed for the exact pinout.
Recomendado
Embedded Equipment Control Logic
The XC95108-7PC84I is suitable for long-lived embedded equipment in which a small amount of nonvolatile, deterministic logic must survive power cycling. On-system FLASH configuration removes the need for a microcontroller to reload the CPLD after every reset, while the 108-macrocell capacity can supervise relays, panel controls, status indicators, and sequencing. The industrial temperature grade is advantageous for equipment operating outside consumer-temperature limits. Care is required because the part operates from 5 V and is a legacy technology; long-term procurement should include independent inspection, date-code controls, and an approved second source.
Recomendado
Equipment Test and Boundary Control
The XC95108's in-system programming and in-system test capabilities make it relevant to legacy production-test fixtures and board boundary-control logic. A single device can implement boundary scan sequencing, fixture multiplexing, pass/fail decisions, and communication between a tester and the unit under test. Its 83.3 MHz operating point and 7.5 ns delay are sufficient for many digital fixture paths, although external instrument timing must dominate the final margin calculation. When replacing the fitted device, verify that the alternative's configuration memory type, programming voltage, JTAG or serial interface, and test-mode behavior remain acceptable for the fixture.

Notas de projeto
Do not treat an identical PLCC outline as proof that any XC95108 speed grade is an exact replacement. The target has a 7.5 ns propagation delay, while the listed alternatives use 5, 7, 10, 15, or 20 ns speed designations. External setup time, hold time, board delay, and clock skew must be rechecked for the actual alternative. Also compare the commercial and industrial suffixes: a faster commercial-grade device may be electrically timing-compatible but unsuitable for the original temperature envelope.
The XC95108 is a 5 V device, so replacement boards must retain compatible supply sequencing, decoupling, and I/O-level design. Place the device's local bypass capacitors close to its supply pins and follow the layout and capacitor values specified in AMD DS066 rather than relying on generic bulk-capacitor guidance. During replacement, confirm that neighboring 3.3 V devices are not exposed to 5 V outputs and that the configuration programming interface remains electrically compatible with the original test or ISP fixture.
Preserve the PLCC-84 mechanical outline, pin numbering, and original PCB footprint when using a same-family alternative. Check J-lead seating, solder-joint geometry, and socket compatibility rather than comparing package height alone. Because the provided excerpts do not include the complete pin table, verify all 84 assignments, power pins, configuration pins, and dedicated I/O pins against the AMD DS066 package drawing and the exact alternate-device data before ordering production quantities.
Re-run static timing analysis after any speed-grade substitution. The target's documented 7.5 ns propagation delay is a device characteristic, not the complete external timing budget; clock period, skew, setup, hold, output loading, and PCB trace delay must also be included. The 15 ns and 20 ns alternatives can consume substantially more timing margin, so a board that works at the original speed grade may fail intermittently after substitution if system timing margin is already small.
Confirm whether the existing configuration file can be reused before planning a migration. Same-family devices with matching outlines may still require recompilation because pin constraints, speed grades, device identifiers, or JEDEC configuration conventions can affect programming and validation. AMD's replacement guidance explicitly calls for evaluating firmware reuse, similar pinouts, I/O voltage levels, electrical characteristics, and long-term availability. Validate one programmed device in the finished system before committing the entire lot.
Informações de conformidade
The verified sources identify an industrial temperature grade but do not explicitly provide RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals statements. AEC-Q100 is not applicable based on the available evidence, and no certification should be inferred from the industrial-temperature marking.
