XC9572-15PC44I - 72-Macrocell 15 ns CPLD | Xilinx
料号： XC9572-15PC44I ✗ 停产XC9572-15PC44I 概述
A CPLD, or complex programmable logic device, is a user-programmable semiconductor that combines programmable logic structures with configuration memory. Within the programmable-logic hierarchy, a CPLD sits between simple programmable logic arrays and higher-capacity FPGAs. The XC9500 family uses Fast FLASH architecture to retain configuration data and support in-system programming, allowing logic designs to be loaded or updated without removing the device from a circuit.
The XC9572-15PC44I provides 72 macrocells and 34 I/O lines, making it suitable for consolidating control logic, interface adaptation, state machines, and fixed protocol functions. Its 15 ns speed designation identifies the timing grade, while the family-level 5 ns pin-to-pin delay provides a basis for high-speed signal-path implementation. Fast FLASH technology and parallel programming support also simplify multi-device configuration or manufacturing workflows.
The XC9500 architecture is organized around macrocells connected through a programmable switch matrix. Each I/O can be assigned appropriate logic or I/O functions, allowing a single device to replace multiple conventional logic devices. Because configuration is nonvolatile, the programmed behavior remains available after power is removed without requiring configuration SRAM to be refreshed by an external controller.
Typical applications include industrial control logic, instrumentation, communications interface logic, test equipment, embedded systems, and legacy peripheral expansion. The industrial temperature grade is appropriate for controlled industrial equipment, while the 44-LCC package offers a through-hole-compatible option for systems assembled with leaded components rather than fine-pitch surface-mount packages.
When replacing this CPLD, verify the package pinout, macrocell density, I/O voltage, temperature grade, and timing grade before substitution. Faster speed-grade variants may provide timing margin, but they can change power characteristics and should not be assumed equivalent without design-level timing review.
This page consolidates verified manufacturer specifications, distributor availability, same-family drop-in candidates, pricing status, pinout availability, and practical replacement guidance. It separates confirmed XC9572-15PC44I data from family-level limits and identifies missing commercial and mechanical details rather than estimating them.

典型应用
XC9572-15PC44I 适用于 6 应用s: Industrial Control Logic, Test and Measurement Instrumentation, Communications Interface Adaptation, Embedded Peripheral Expansion, LED Lighting and Display Control, Programmable Test Fixture Logic.
Industrial Control Logic
XC9572-15PC44I fits industrial control logic that requires nonvolatile configuration, 72 macrocells, and 34 available I/O lines. Its 15 ns speed grade supports control paths, interlocks, and state-machine timing, while the industrial-temperature designation targets factory equipment. The 44-LCC J-lead package also suits assemblies using through-hole-compatible leaded components. According to the XC9572 manufacturer data sheet, 5 V Fast FLASH configuration permits in-system programming, allowing field updates without removing the device.
推荐
Test and Measurement Instrumentation
XC9572-15PC44I can implement trigger sequencing, acquisition control, status decoding, and front-panel logic in test and measurement instruments. Its 72 macrocells provide more capacity than a small discrete-logic implementation, while the 34 I/O lines support instrument buses, relays, indicators, and control signals. The family-level 5 ns pin-to-pin delay helps preserve timing margin in high-speed acquisition paths, and nonvolatile Flash configuration simplifies repeatable instrument startup.
推荐
Communications Interface Adaptation
XC9572-15PC44I is useful for legacy communications interface adaptation, including protocol translation, framing, FIFO control, and programmable I/O conditioning. Its 34 I/O lines permit several interface signals to be consolidated into one device, while 72 macrocells support moderate state-machine complexity. The XC9500 family's parallel programming capability is useful when several communication-support devices must be configured consistently during manufacturing or maintenance.
推荐
Embedded Peripheral Expansion
XC9572-15PC44I can expand legacy embedded-system I/O without changing the controller architecture. Its programmable macrocells can decode interrupts, implement timers, translate pin polarity, or arbitrate among peripheral devices. With 72 macrocells and 34 I/O, it offers more integration than basic 74HC-series logic while retaining deterministic timing. The 5 V Fast FLASH architecture also preserves configuration across power cycles, reducing repeated firmware initialization of equivalent discrete logic.
推荐
LED Lighting and Display Control
XC9572-15PC44I is appropriate for deterministic display sequencing, LED bank control, keypad scanning, and status multiplexing. Its 34 I/O lines can distribute control signals among multiple display or indicator groups, while the 15 ns grade supports short update intervals and synchronizing multiple control paths. The industrial-temperature designation makes it suitable for illuminated panels in controlled industrial environments, subject to the detailed I/O and supply limits in DS065.
推荐
Programmable Test Fixture Logic
XC9572-15PC44I can coordinate test fixtures by generating stimulus patterns, switching control signals, and responding to measurement equipment. The 72-macrocell capacity supports parallel fixture channels and modest sequencing logic, while 34 I/O lines provide connection to probes, relays, and programmable sources. Its in-system programming support permits fixture patterns to be updated quickly, and the leaded 44-LCC package remains practical for prototype boards and manually wired engineering fixtures.

关键差异点
- Exact 15 ns speed-grade alternative within the XC9572 family （对比 XC9572-15PCG44I)
- Additional timing margin from a faster same-density grade （对比 XC9572-10PC44I)
- Industrial-temperature qualification in the ordered target （对比 XC9572-15PC44C)
设计说明
Do not treat a faster XC9572 suffix as automatically identical to XC9572-15PC44I. The 10 ns and 7 ns grades change timing and may alter dynamic power and electromagnetic behavior. Compare the complete ordering codes, confirm the 44-LCC footprint, and rerun worst-case timing analysis. Also verify the commercial-versus-industrial suffix because XC9572-15PC44C cannot replace the I-grade target outside its specified temperature range.
Follow the DS065 supply and I/O limits exactly. The verified data states that external I/O voltage may not exceed VCCINT by 4.0 V. During transitions, pins may overshoot to +7.0 V or undershoot to -2.0 V for less than 10 ns when forcing current is limited to 200 mA, while sustained DC undershoot below ground must remain within 0.5 V or 10 mA. These constraints affect external bus design and protection networks.
Preserve a pin-compatible 44-LCC footprint and route the configuration interface according to the manufacturer programming guidance. Because multiple XC9500 devices can be programmed in parallel, keep programming-mode control and data routing electrically consistent across the board. Review signal-integrity behavior at the supported 5 V logic level and provide appropriate decoupling close to the device power pins; exact capacitor values and pin names require the complete DS065 pinout and power recommendations.
