AMD XA9536XL-15VQG44I

Overview

XA9536XL-15VQG44I from AMD is a programmable logic device in the XC9500XL line intended for glue logic, state sequencing, and local interface adaptation. With 36 macrocells and a 44-pin TQFP footprint that suits compact routing around processors, ASICs, and interface devices, it is positioned for boards that need fixed startup behavior, field programmability, and more flexible digital control than hardwired gates can offer. Its specific suffix matters because 15ns-grade orderable option. and the industrial temperature option indicated by the suffix. determine whether this exact option matches the board timing budget, package choice, and qualification target rather than only the base family architecture.

The XA9536XL family is the automotive-oriented branch of the XC9500XL CPLD line for low-voltage programmable logic, glue logic integration, and deterministic board-level control functions. For engineers reviewing the XA9536XL-15VQG44I datasheet, XA9536XL-15VQG44I pinout, XA9536XL-15VQG44I application, or XA9536XL-15VQG44I equivalent, this device is widely used in interface glue logic, control sequencing, bus adaptation, industrial embedded modules, communications equipment, and programmable board-support designs.

Technical Context

For embedded platforms, XA9536XL-15VQG44I is typically assigned to board-support logic tasks such as chip-select handling, mode control, handshake conditioning, and local bus adaptation. The 36-macrocell density gives this device enough room to consolidate functions that would otherwise sit across multiple smaller logic parts.

Board designers usually care about this exact suffix because package geometry, timing grade, and operating range can all change final fit decisions. For XA9536XL-15VQG44I, the combination of 44-TQFP, 15ns-grade orderable option., and the industrial temperature option indicated by the suffix. directly influences how confidently the part can be placed into a validated BOM.

The XA9536XL line keeps the XC9500XL architectural behavior while aligning the orderable options with broader environmental and automotive-focused validation needs. That makes XA9536XL-15VQG44I a practical choice for interface glue logic, supervisory state handling, timing coordination, and programmable board management in systems that value predictable CPLD behavior.

Applications

Equivalent & Alternatives

When evaluating a XA9536XL-15VQG44I equivalent, engineers should compare macrocell count, package, timing grade, operating range, architecture continuity, and board-level logic-fit requirements.

Compared with XA9536XL-15VQG44Q, XA9536XL-15VQG44I selection depends on exact package, speed grade, and suffix fit within related CPLD classes. XA9536XL-15VQG44I vs XC9536XL-10VQG44C selection depends on whether the design should stay with the same CPLD architecture or move to a different programmable-logic branch with other power or logic-density tradeoffs.

Quality

XA9536XL-15VQG44I should be sourced as original AMD programmable logic inventory through traceable supply channels. Quality checks may include package inspection, top-mark validation, JTAG-programming verification, and logic-image loading review.

Production validation should include timing-closure review, I/O-voltage checks, boundary-scan access, power-integrity verification, and signal-integrity assessment on high-activity control and interface nets.

Availability

XA9536XL-15VQG44I is suitable for programmable board-support logic, interface control, and deterministic CPLD integration in communications, computing, industrial, and embedded systems.

Supply support may include volume procurement planning, scheduled delivery arrangements, traceable sourcing management, and long-term supply support for OEM, industrial electronics, automotive electronics, and embedded product programs. Sample and NPI supply support, as well as urgent in-stock supply support, can also be arranged for prototype builds, pilot runs, and time-critical production needs.

For production builds, confirming package option, speed grade, operating-range suffix, lifecycle status, and sourcing continuity helps reduce programmable-logic procurement risk.
