XC9572-10PC84I - 72-Macrocell 10ns 5V CPLD | Xilinx
N.º da peça: XC9572-10PC84I ✗ Fim de vidaXC9572-10PC84I Visão geral
A CPLD is a programmable-logic device that converts Boolean equations and state-machine descriptions into a configurable digital circuit. Positioned within the FPGA and CPLD category, it provides deterministic combinational and registered logic through a nonvolatile Flash architecture. Unlike a mask-programmed custom ASIC, a CPLD allows logic changes to be programmed or reprogrammed after manufacture, shortening product-development and field-update cycles.
The XC9572 provides 72 macrocells, approximately 1,600 usable gates, and up to 72 user I/O positions according to the family-level product specification. Its 5 V in-system programming interface supports a minimum of 10,000 program-and-erase cycles. Parallel programming of multiple XC9500 devices is also supported, making the device suitable for replicated or coordinated logic sections within larger 5 V systems.
The -10 speed grade corresponds to a nominal 10 ns propagation-delay class, while the family is specified for a 7.5 ns pin-to-pin delay on all pins and fCNT operation to 125 MHz. The device uses Advanced CMOS 5V Fast FLASH technology and provides a deterministic architecture suited to control logic, interface decoding, bus arbitration, state machines, and legacy peripheral emulation.
Typical applications include industrial control, test and measurement equipment, printer and display controllers, embedded system glue logic, and peripheral compatibility designs. Its 69 I/O pins provide substantial connectivity for parallel buses and multi-bit interfaces, while 5 V operation supports systems that already use 5 V CMOS logic.
When designing around this legacy CPLD, verify all 84 package positions against the DS065 pin-description tables and confirm that 5 V signal levels do not exceed the device limits. A replacement program should also verify timing, ISP behavior, pin assignment, and industrial temperature requirements rather than relying only on package dimensions.
This product page combines the device specifications, package constraints, practical logic-design guidance, and same-family replacement options to support legacy CPLD design reviews, maintenance programs, and controlled board-level modernization.

Aplicações típicas
XC9572-10PC84I é adequado para 6 aplicaçãos: Industrial Control Logic, Test and Measurement Control, Printer and Display Interface Control, Bus Arbitration and Interface Decoding, Embedded System Compatibility, Programmable Security and Interlock Logic.
Industrial Control Logic
The XC9572-10PC84I fits legacy industrial controllers that require deterministic glue logic beside a microprocessor or microcontroller. Its 72 macrocells and 69 user I/O pins can implement state machines, interlocks, alarm decoding, and parallel interface control, while the 10 ns speed grade provides a 33% lower nominal propagation delay than the 15 ns XC9572-15PC84I. The device is placed between 4.5 V to 5.5 V system rails and programmed through the XC9500 5 V ISP interface. Care is required around industrial surge and grounding because the CPLD provides logic control rather than input isolation.
Recomendado
Test and Measurement Control
The XC9572-10PC84I is suitable for legacy test and measurement equipment that coordinates instrument interfaces, status decoding, and timing-sensitive control paths. Its 7.5 ns pin-to-pin delay and fCNT operation up to 125 MHz support faster combinational sequencing than slower legacy CPLD grades, while 1,600 usable gates provide practical logic consolidation. Engineers can assign parallel bus decode, trigger multiplexing, and front-panel state functions around the 69 available I/O pins. Timing closure should remain based on the device speed grade and external loading rather than the nominal 10 ns designation alone.
Recomendado
Printer and Display Interface Control
The XC9572-10PC84I can implement printer, display, and legacy peripheral interface controllers where fixed logic must be updated in the field. Seventy-two macrocells are suitable for command sequencing, bus arbitration, character-generation control, and status multiplexing, and the 69 user I/O pins support parallel data and control lines. In-system programming allows a board revision to reuse the same PLCC footprint for firmware or configuration changes. Because the device operates from 4.5 V to 5.5 V, interface voltage levels, termination, and signal-integrity requirements should be checked against each attached peripheral.
Recomendado
Bus Arbitration and Interface Decoding
The XC9572-10PC84I is a practical choice for arbitration, address decoding, and peripheral-select logic in 5 V embedded systems. Its 72 macrocells can implement multiple decode equations and registered state machines, while the 10 ns grade offers useful timing margin compared with the 15 ns XC9572-15PC84I. The 69 user I/O pins allow direct connection to shared buses, interrupt outputs, and control lines without an external CPLD. Designers should analyze setup and hold requirements for every registered path and include ISP pins, power pins, and grounds exactly as defined in the manufacturer pin-description table.
Recomendado
Embedded System Compatibility
The XC9572-10PC84I supports maintenance of embedded systems that combine 5 V CMOS peripherals with newer control silicon through programmable adapter logic. Its in-system programming capability permits configuration updates without a dedicated socket, and the nonvolatile Flash architecture supports at least 10,000 program-and-erase cycles. The device can translate legacy signals, implement boot sequencing, and bridge asynchronous control lines. This is particularly useful when replacing discontinued glue devices without changing the 84-pin PLCC board footprint. Complete replacement qualification must still include timing analysis, power sequencing, programming-file compatibility, and environmental testing.
Recomendado
Programmable Security and Interlock Logic
The XC9572-10PC84I can implement configurable access-control, key-sequence, and equipment-interlock logic for legacy industrial equipment. Its 72 macrocells support parallel comparisons, latch-based state transitions, and redundant enable conditions, while the 10 ns class helps preserve sequencing margin relative to the 15 ns XC9572-15PC84I. Because configuration is stored in nonvolatile Flash, the interlock behavior remains fixed through power cycles. A security assessment should account for programming access, configuration-file controls, diagnostic interfaces, and the fact that logic interlock functions do not replace independent protective hardware.

Principais diferenciais
- Faster nominal timing than the 15 ns family alternatives (vs XC9572-15PC84I)

- Same speed grade with a different commercial temperature ordering option (vs XC9572-10PC84C)
Notas de projeto
Do not treat matching PLCC dimensions as sufficient proof of drop-in compatibility. Verify every numbered pin in the DS065 pin-description table, including VCC, ground, programming inputs, clock inputs, and user I/O functions. The XC9572-10PC84C shares the 10 ns speed grade but uses the C temperature suffix, while the XC9572-15PC84I preserves the I suffix but has a 50% slower nominal propagation delay than the target.
Route the 5 V programming interface and associated control signals away from high-speed switching nodes, and place bypass capacitors close to the device power pins. Preserve the manufacturer's PLCC land pattern and orientation because the 84-pin package offers no mechanical tolerance for a shifted or reversed part. Confirm ground-plane continuity and programming-signal levels against the board’s power architecture before production release.
Use the 7.5 ns pin-to-pin delay and 125 MHz fCNT capability as family-level timing points, not as blanket guarantees for every external path. Timing closure must include package, load, board interconnect, setup and hold requirements, and the selected speed grade. XC9572-7PC84I offers a faster timing option, but changing the grade does not remove the need to recompile and validate the design.
The XC9572-10PC84I operates from 4.5 V to 5.5 V, so a nominal 5 V rail must remain inside that range under load and tolerance. Provide suitable 5 V programming infrastructure because the device is specified for 5 V in-system programming. Review current consumption, power-up sequencing, and I/O-drive behavior for every connected interface rather than inferring safe levels from the supply rating alone.
Informações de conformidade
The device is listed as containing lead and RoHS non-compliant. Reach, halogen-free, and conflict-minerals status are not stated. AEC-Q100 status is not applicable because this is a legacy programmable-logic IC rather than an automotive-qualified device.
