XC9572-7TQ100C - 72-Macrocell 5V CPLD | AMD | Industrial Control
N.º de pieza: XC9572-7TQ100C ✗ Fin de vidaXC9572-7TQ100C Descripción general
A complex programmable logic device, or CPLD, is a user-programmable semiconductor that combines AND-OR logic structures with nonvolatile configuration memory. The XC9500 architecture organizes its logic into macrocells, each supporting programmable interconnect and registered or combinational functions. The XC9572 provides 72 macrocells and 72 I/O, making it suitable for consolidating multiple fixed-function gates, control registers, address decoding, and peripheral interfaces onto one device.
The -7 speed grade specifies a maximum propagation delay of 7.5 ns, while the family is also described as supporting 5 ns pin-to-pin logic delays and a maximum counter frequency of 125 MHz. In-system programmability allows the configuration to be updated without removing the device from the circuit, and the architecture supports at least 10,000 program and erase cycles. Parallel programming can also update multiple XC9500 devices concurrently.
The XC9572 uses a 5 V internal supply architecture, with a documented operating range of 4.75 V to 5.25 V. Its nonvolatile FastFLASH configuration technology retains the programmed logic after power is removed, avoiding repeated configuration loading after every power cycle. The device also supports in-system testing, which helps production teams verify assembled boards and isolate board-level interconnect faults.
Typical uses include industrial control and sequencing logic, legacy peripheral expansion, data acquisition interfaces, memory-control glue logic, and board-level test or debug infrastructure. The combination of 72 I/O and a 100-pin surface-mount package allows substantial signal connectivity without moving to a larger programmable-logic device.
When designing around this device, retain the original XC9500 schematic, package, and timing constraints rather than treating newer CPLD families as direct replacements. Verify every supply rail, termination input, and pin assignment against DS065. Because the device is listed as obsolete, long-lived programs should evaluate an approved migration path before releasing new production quantities.
This page organizes the obsolete-status notice, package details, programming characteristics, pin-compatible options, and practical replacement considerations. It also distinguishes same-footprint candidates from alternatives with different voltage architectures, helping engineers evaluate board reuse without overlooking configuration, timing, and lifecycle constraints.

Aplicaciones típicas
XC9572-7TQ100C es adecuado para 6 aplicacións: Industrial Control and Sequencing, Legacy Peripheral Interface Consolidation, Data Acquisition and Signal Conditioning, Memory and Bus Interface Logic, Programmable Test and Diagnostics, Security and Access-Control Control.
Industrial Control and Sequencing
The XC9572-7TQ100C fits deterministic industrial control blocks that combine state machines, interlocks, sequencing, and discrete I/O in one programmable device. Its 72 macrocells and 72 I/O allow several control functions to replace separate gate logic, while the -7 grade provides a 7.5 ns maximum pin-to-pin delay for timing evaluation. The 4.75 V to 5.25 V internal supply suits legacy 5 V control systems. Designers should partition critical interlocks into independent protection hardware, reserve sufficient I/O for isolation and field wiring, and validate every path against DS065 timing limits.
Recomendado
Legacy Peripheral Interface Consolidation
The XC9572-7TQ100C is useful when an existing board contains several incompatible asynchronous interfaces, address decoders, and handshake circuits. Seventy-two macrocells can implement control logic around registers or latches, while 72 I/O provide board-level connections in a 100-pin TQFP. In-system programming permits configuration updates during test or maintenance without removing the package. Because the device targets a 5 V architecture, external buffers may be required for modern 3.3 V peripherals. Confirm setup times, output drive, input thresholds, and configuration-pin requirements in the manufacturer data sheet before finalizing the interface matrix.
Recomendado
Data Acquisition and Signal Conditioning
The XC9572-7TQ100C can implement deterministic acquisition-control logic around slower sensors, counters, sample-and-hold sequencing, and data-capture registers. Its 72 macrocells support pipeline stages and parallel data movement, and the 7.5 ns maximum pin-to-pin delay provides a defined basis for interface timing analysis. The CPLD does not replace analog front-end design, so sensor excitation, amplification, filtering, and grounding remain separate analog considerations. Keep high-speed or noise-sensitive analog paths physically separate from programming and switching nodes, and use DS065 timing and AC characteristics to establish setup and hold margins.
Recomendado
Memory and Bus Interface Logic
The XC9572-7TQ100C can consolidate address decoding, command qualification, interrupt masking, and peripheral-select logic in a legacy embedded system. Its 72 macrocells and 72 I/O are sufficient for multiple simple bus targets, while nonvolatile FastFLASH configuration preserves the logic image across power cycles. The device should be used only where the required bus timing and I/O levels match its documented 5 V implementation. Designers should analyze contention, driven versus open-drain signals, and clock-domain boundaries. If a newer microcontroller already integrates the required peripherals, validate the CPLD’s added area and timing benefit before retaining it.
Recomendado
Programmable Test and Diagnostics
The XC9572-7TQ100C is appropriate for board-level test logic that routes diagnostic signals, generates stimulus patterns, records fault indications, or controls production test fixtures. Its in-system programming and in-system test capabilities reduce fixture complexity, and parallel programming supports efficient configuration of multiple XC9500 devices during production. The 72 I/O can be assigned to test points and instrument interface signals. Keep test access away from safety-critical outputs, account for powered-system back-drive at connector pins, and validate programming isolation so test equipment cannot conflict with normal operating circuitry.
Recomendado
Security and Access-Control Control
The XC9572-7TQ100C can coordinate lock sequencing, keypad scanning, request inputs, alarm outputs, and status indicators in a low-complexity access-control panel. Seventy-two macrocells provide enough deterministic logic for multiple I/O workflows, while in-system programmability permits controlled configuration updates during commissioning. The 0 °C to 70 °C commercial rating must be checked against the intended enclosure temperature, and the device is not listed as RoHS compliant. Security designs should include physical tamper detection and fail-safe actuator behavior rather than relying on programmable logic alone for life-safety functions.

Notas de diseño
Do not treat a matching 100-pin package as proof that a candidate can replace the XC9572-7TQ100C. The XC9572XL options are identified as 3.3 V devices, while the target uses a 4.75 V to 5.25 V internal supply. Before replacing the component, compare DS065 pin tables, supply requirements, configuration interface behavior, AC timing, and I/O electrical characteristics. If any item differs, add interface circuitry or retain the original architecture.
Assign the PCB footprint from the official TQFP-100 package drawing and DS065 pin table rather than from a generic QFP library. Place programming and configuration connections in a predictable location for boundary-scan or fixture access, and keep sensitive analog or high-speed routing away from the programming interface. Confirm pin 1 orientation, exposed-pad treatment if any, solder mask clearance, and assembly allowances against the package drawing before releasing artwork.
Design the 5 V rail for the XC9572-7TQ100C with suitable bypass and adequate sequencing margin. The documented internal operating range is 4.75 V to 5.25 V, so rail tolerance, startup ramp, and attached-load transients must remain inside that interval. Decouple close to the supply pins and account for configuration pins or shared supply rails when the board is also used for in-system programming. Validate the complete power state against DS065 rather than relying on a single nominal supply value.
