Product details
Overview
XCR3256XL-10TQ144I from AMD (acquired by Xilinx) is a 3.3 V in-system programmable CPLD with 256 macrocells, 10 ns propagation delay, and 144-pin TQFP package; used in legacy industrial control logic replacement and FPGA configuration glue logic.
For engineers reviewing the XCR3256XL-10TQ144I datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (118 user I/Os), supply voltage tolerance (3.3 V ±10%), in-system programmability via JTAG, and -40°C to +85°C industrial temperature grade.
Technical Context
This device belongs to the XCR3000XL family of high-performance, low-power CPLDs built on 0.35 µm CMOS technology. It implements registered and combinatorial logic using sum-of-products architecture with programmable interconnect and global clock routing.
The XCR3256XL-10TQ144I supports IEEE 1149.1 JTAG boundary-scan testing and in-system programming through dedicated ISP pins. Its macrocell structure includes configurable flip-flops with synchronous/asynchronous reset and preset, and product-term sharing across function blocks.

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based logic replacement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3256XL-12TQ144I | 12 ns propagation delay vs. 10 ns; identical macrocell count, I/O count, and package. | Suitable where 10 ns timing margin is not required; lower cost due to relaxed speed bin. | Select when system clock domains operate below 80 MHz and cost optimization is prioritized over worst-case timing headroom. |
| XC95288XL-10TQ144I | 288 macrocells, same 10 ns speed grade, but larger die size and higher static current (≈120 mA). | Better suited for designs requiring >256 logic functions or deeper state machines without partitioning. | Choose XC95288XL-10TQ144I only if additional macrocells are needed-XCR3256XL-10TQ144I remains optimal for 256-cell logic density with lower power. |
Compared with XCR3256XL-10TQ144I, the -12 speed grade trades 2 ns timing for cost reduction, while XC95288XL-10TQ144I adds macrocell capacity at the expense of higher power and footprint-making XCR3256XL-10TQ144I the balanced choice for mid-density, low-power industrial glue logic.

FAQ
What is the maximum operating frequency supported by XCR3256XL-10TQ144I?
The XCR3256XL-10TQ144I has a 10 ns maximum propagation delay, enabling reliable operation up to 100 MHz in register-to-register paths. Actual system frequency depends on logic depth and routing; typical sustained clock rates in industrial control applications range from 60–85 MHz with full timing closure.
Does XCR3256XL-10TQ144I require an external configuration PROM?
No. The XCR3256XL-10TQ144I contains on-chip non-volatile configuration memory and powers up fully functional without external PROM. Configuration is retained after power loss, eliminating boot-time delays and external component dependencies.
Can XCR3256XL-10TQ144I be reprogrammed in the field without removing it from the PCB?
Yes. The XCR3256XL-10TQ144I supports IEEE 1149.1 JTAG-based in-system programming. Engineers can update logic functionality in the field using standard JTAG adapters, without desoldering or socket replacement-critical for deployed industrial systems.
What is the I/O voltage compatibility of XCR3256XL-10TQ144I?
The XCR3256XL-10TQ144I operates at 3.3 V VCCIO and supports LVTTL and LVCMOS signaling standards. Input thresholds are compatible with 3.3 V logic families, and outputs drive directly into 3.3 V loads without level shifters or series resistors.
Is XCR3256XL-10TQ144I qualified for automotive applications?
No. The XCR3256XL-10TQ144I is rated for industrial temperature range (-40°C to +85°C) and is not AEC-Q100 qualified. For automotive use, engineers should consider Xilinx Automotive-grade XC9500XL variants or newer AMD/Xilinx automotive-qualified CPLDs.
