XC9572XL-7VQ64C - 72-Macrocell 3.3V CPLD | AMD
料号： XC9572XL-7VQ64C ✗ 停产XC9572XL-7VQ64C 概述
A CPLD is a programmable digital logic device that combines a structured array of macrocells with a global interconnect. Unlike a software-driven processor, a CPLD executes combinational and registered logic directly in hardware. Within the semiconductor hierarchy, this part is a complex programmable logic device, a user-programmable logic device, and ultimately an integrated circuit designed for deterministic logic implementation.
The XC9500XL architecture provides individual output enable for each output pin, local inversion, input hysteresis on user and boundary-scan inputs, and bus-hold circuitry on user inputs. These features support dependable control of external signals, improved noise tolerance, and stable handling of partially driven buses. The family also supports hot-plugging capability and IEEE boundary-scan-oriented verification functions.
For the XC9572XL-7VQ64C, the 72-macrocell architecture provides a practical balance between logic density and design effort. A 7 ns speed grade and 125 MHz maximum operating frequency support communication, control, and data-processing functions that require predictable timing. The 64-pin VQFP package provides 52 user I/O according to the published family listing while leaving dedicated supply and configuration functions.
Typical applications include legacy peripheral emulation, printer and industrial-control interfaces, programmable logic glue, bus arbitration, data-format conversion, and system boot or sequencing logic. The in-system programming architecture also supports board-level configuration workflows where a programmed device must be updated without removing it from its assembled circuit.
Designers should preserve the XC9500XL power architecture and decoupling strategy, leave configuration and test behavior consistent with the AMD DS057 data sheet, and verify every external interface against the selected package pinout. Device selection also requires checking tool-chain compatibility because this established CPLD family is normally programmed with AMD/Xilinx CPLD development tools and appropriate JTAG programming hardware.
This product page combines the AMD family architecture, verified family variants, pin-compatible alternatives, application guidance, and practical implementation considerations in one engineering-focused reference. It supports faster device identification while highlighting the speed-grade and temperature-grade distinctions that can affect an existing design.

典型应用
XC9572XL-7VQ64C 适用于 6 应用s: Legacy Peripheral Interface Control, Industrial Bus Arbitration and Decoding, Programmable System Boot and Sequencing, Printer and Data-Acquisition Control, In-System Reconfiguration Control, Communication Interface Glue Logic.
Legacy Peripheral Interface Control
The AMD XC9572XL-7VQ64C is appropriate for consolidating legacy peripheral control into one deterministic hardware logic device. Its 72 macrocells provide space for address decoding, register strobes, interrupt control, and data-format conversion without introducing a CPU execution dependency. The 125 MHz maximum frequency and 7.5 ns stated propagation-delay class provide margin for ordinary control paths, while the 52 user I/Os support multiple parallel interface signals. Individual output enables allow tri-state control of bus transceivers, and bus-hold circuitry helps maintain defined states during configuration transitions. Final timing should be checked against the slowest external peripheral and the device's complete AC characteristics in AMD data sheet DS057.
推荐
Industrial Bus Arbitration and Decoding
The XC9572XL-7VQ64C can implement deterministic arbitration, address decoding, and protocol handshaking for established industrial or embedded bus architectures. With 72 macrocells, a design can combine command decoding, timeout handling, interrupt qualification, and state-machine logic while retaining 52 user I/Os for bus participants. Input hysteresis on user inputs improves noise tolerance, while per-output enable control supports shared-bus signaling. The 3.3 V supply arrangement aligns the CPLD with conventional 3.3 V interface logic, and the -7 speed class supports a 125 MHz device-frequency ceiling. Engineers should verify setup and hold timing against each external bus device and include the exact package pin assignment from DS057.
推荐
Programmable System Boot and Sequencing
The AMD XC9572XL-7VQ64C is useful for board-level power sequencing, reset generation, and startup-state control in legacy embedded platforms. A hardware state machine can enforce deterministic ordering among clocks, regulators, peripherals, and bus interfaces without loading a host processor. Its 125 MHz maximum operating frequency is more than sufficient for supervisory sequencing, while the 72 macrocells allow multiple independent channels and status-reporting logic. Local inversion can simplify implementation of active-high or active-low control conventions, and individual output enable provides direct control over external buffer paths. The design should identify every startup state, define safe defaults before configuration, and verify the I/O states during power transitions against the manufacturer's boundary-scan and electrical guidance.
推荐
Printer and Data-Acquisition Control
The XC9572XL-7VQ64C fits legacy printer, data-acquisition, and instrument-control boards that require deterministic data movement and multiple discrete control functions. Its 52 user I/Os can support parallel data, handshake, and status signals, while 72 macrocells can host command interpreters, data registers, and sequencing state machines. The 125 MHz device frequency and 7.5 ns stated propagation-delay class support common control-clock environments without relying on software timing loops. Bus-hold circuitry is beneficial when control signals can be temporarily released, and per-pin output enable permits direct tri-state control of external buses. Timing closure must include external connector, driver, and receiver delays, while the complete PCB must follow the package-specific land pattern and grounding guidance in DS057.
推荐
In-System Reconfiguration Control
The XC9572XL-7VQ64C supports in-system programming and boundary-scan-based verification, making it appropriate for boards that need controlled logic updates or test access without removing the device. A board-level controller can use the programming interface to load a configuration, verify boundary-scan behavior, and coordinate reset of attached logic. The architecture's hot-plugging capability and bus-hold features support controlled transitions on partially implemented systems, although power sequencing and I/O-state requirements still need careful validation. With 72 macrocells, configuration gating and auxiliary logic can coexist with the primary application. Engineers should follow the boundary-scan pin definitions, programming voltage requirements, and recommended JTOB/TCK/TMS/TDI/TDO arrangements in AMD data sheet DS057.
推荐
Communication Interface Glue Logic
The XC9572XL-7VQ64C can bridge mismatched communication interfaces by implementing framing, baud-related division, parity, checksum, and protocol state management in hardware. Its 72 macrocells allow multiple protocol channels or a combination of data transformation and flow control, while 52 user I/Os provide the required parallel and serial-facing pins. The -7 speed grade and 125 MHz maximum frequency provide useful timing margin for moderate-rate links, and local inversion can reduce gate-level complexity when interface polarity differs between components. Input hysteresis improves noise immunity on received lines, while individual output enables support multiplexed buses. The design must include reset-safe states, verify serial timing against the chosen transceiver, and ensure each interface's signal direction is assigned through the correct package pin.

设计说明
Use the 64-pin VQFP land pattern and pin definitions from AMD data sheet DS057 rather than a generic 64-pin footprint. Place the required supply-decoupling components close to the device power pins, connect all specified ground pins, and route JTAG signals away from high-current switching paths. Because the XC9572XL family supports in-system programming and hot-plugging, the layout should preserve access to the programming interface and avoid loading configuration pins through components that interfere with normal operation.
Treat clock, configuration, and JTAG nets as constrained signals. Keep JTOB, TCK, TMS, TDI, and TDO paths short, use a continuous reference plane, and avoid stubs where possible. Boundary-scan operation and in-system programming can expose the device to temporary transitions on these nets, so external pull resistors or controlled drivers should follow the manufacturer's guidance. Validate setup and hold timing at the actual board temperature rather than relying only on nominal timing figures.
Do not substitute only by macrocell count or package pin count. The -5 and -7 designations identify different speed grades, while C and I identify different temperature grades. A mechanically similar package with a different suffix may fail timing or environmental requirements even when the pin arrangement appears identical. Record the exact ordering code, programmed bitstream compatibility, temperature requirements, and lifecycle risk before approving a replacement for the XC9572XL-7VQ64C.
Design the 3.3 V supply path around the device's exact recommended operating limits, startup behavior, and I/O loading in DS057. Decoupling requirements must be placed according to the manufacturer's layout guidance, and unused I/O pins must be assigned to defined states in the design tool. Check that external drivers connected to a pin do not exceed the specified I/O current or voltage limits, particularly during configuration, reset, and hot-plug transitions.
合规信息
The published XC9572XL-7VQ64C listing identifies the device as RoHS compliant. No separate REACH, halogen-free, conflict-minerals, or lead-free statement was established for the exact MPN.
