XCR3128XL-10TQ144C

Product Overview

XCR3128XL-10TQ144C is a 128-macrocell CoolRunner XPLA3 complex programmable logic device associated with AMD / Xilinx. It is intended for deterministic control, address decoding and interface logic, where nonvolatile configuration, predictable timing and board-level logic integration are more important than the large reconfigurable fabric used in an FPGA. The complete ordering code identifies a specific speed, package and temperature option and must be preserved when qualifying replacement material.

This ordering variant belongs to the 3.3 V low-power family. The -10 speed token identifies its timing grade. The code resolves to TQFP, 144 terminals. It also carries a commercial-temperature ordering suffix. These suffix details affect PCB footprint, I/O availability, timing closure and environmental qualification; they are not cosmetic ordering differences.

Architecture and Technical Characteristics

CoolRunner XPLA3 uses an extended programmable logic array architecture optimized for Fast Zero Power operation. Function blocks, flexible product terms and a global routing structure support state machines and wide decode functions while retaining configuration without an external boot memory. JTAG in-system programming permits field loading of the design, but package-specific JTAG pin positions and I/O voltage rules must be checked before substitution.

Key Features

• Manufacturer / historical brand: AMD / Xilinx
• Full part number: XCR3128XL-10TQ144C
• CPLD family: CoolRunner XPLA3
• Logic capacity: 128 macrocells
• Logic organization: manufacturer-defined macrocell/function-block architecture
• Configuration technology: Fast Zero Power nonvolatile CPLD
• Voltage class: 3.3 V low-power family
• Speed-grade designator: -10; guaranteed timing must be taken from the exact device speed table
• Package / pin count: TQFP, 144 terminals
• Temperature / qualification: commercial-temperature ordering suffix
• Programming requirement: verify JTAG/ISP algorithm, chain file and programming-voltage conditions for the exact device
• Configuration file: blank stock requires the correct JEDEC, SVF or vendor-supported programming data before it can replace a programmed unit

Applications

• Address decoding and chip-select generation
• Reset, power sequencing and supervisory control
• Bus bridging, protocol glue and interface qualification
• Deterministic finite-state machines
• Higher-density board-control consolidation and peripheral management
• Portable, communications and power-sensitive control logic

Design and Replacement Considerations

Before replacing this device, compare macrocell capacity, usable I/O for the selected package, core and I/O rails, input tolerance, global clock and reset resources, power-up behavior, JTAG pinout and guaranteed propagation/setup/clock-to-output timing. Preserve the original project and programming file. A blank CPLD does not contain the customer function, and a JEDEC or SVF file compiled for a related density or package must not be assumed compatible. When migrating to another family, recompile, rerun fitter constraints and perform timing and board-level voltage validation.

Quality & Sourcing

For XCR3128XL-10TQ144C, Antrex Electronics can support stock and lead-time checks, full-suffix confirmation, package and date-code review, product photographs, label inspection and shipment planning. Buyers should state whether blank or pre-programmed parts are required and provide the target quantity, acceptable date code, packaging form and inspection requirements. For discontinued or long-stored CPLDs, recommended controls include traceability review, marking comparison, lead and ball-condition inspection, solderability evaluation and third-party electrical or X-ray testing when risk warrants it. OEMs, EMS providers, repair centers and component buyers may submit BOM lists and hard-to-find programmable-logic requirements for sourcing support.
