Product details
Overview
XC9536XL-10VQ64I from AMD (acquired by Xilinx) is a 36-macrocell CPLD in VQFP-64 package, with 10 ns propagation delay, 5 V tolerant I/O, and in-system programmable via JTAG. It serves as logic replacement in legacy industrial control interfaces requiring deterministic timing and reconfigurable glue logic.
For engineers reviewing the XC9536XL-10VQ64I datasheet, pinout, applications, or equivalent options, key selection criteria include macrocell count, pin-compatible migration path from XC9536-10VQ64, I/O voltage tolerance, and JTAG-based field reprogrammability without power cycle.
Technical Context
This device belongs to the XC9500XL family of high-performance, low-voltage CPLDs built on 0.35 µm CMOS technology. It implements registered and combinatorial logic using macrocells with configurable product-term architecture, shared expanders, and global clock/reset controls.
Logic density is fixed at 36 macrocells with up to 80 product terms per macrocell. The architecture supports asynchronous reset, synchronous preset, and individual macrocell output polarity control - all configurable via ISP software without hardware changes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocell Count | 36 macrocells provide sufficient logic for small-state machines or bus interface glue logic in legacy systems. |
| Propagation Delay | 10 ns max ensures timing compliance in 50 MHz–80 MHz control paths with minimal skew. |
| I/O Voltage Range | 5 V tolerant inputs allow direct interfacing with TTL/CMOS logic without level shifters. |
| Package | VQFP-64 (10 mm × 10 mm) enables drop-in replacement in existing PCB footprints designed for XC9536-10VQ64. |
| JTAG Support | IEEE 1149.1-compliant boundary-scan enables in-system programming and verification without socketing. |
| Supply Voltage | 3.3 V core supply reduces power vs. older 5 V CPLDs while maintaining 5 V I/O compatibility. |
Pinout & Package
VQFP-64 (Very Thin Quad Flat Package), 10 mm × 10 mm body, 0.5 mm lead pitch, thermally enhanced plastic construction with exposed thermal pad (non-electrical).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Multiple dedicated pins ensure low-impedance return paths for logic and I/O domains. |
| VCC | Core power supply | 3.3 V supply for internal logic; decoupling required within 1 cm of each VCC pin. |
| VCCIO | I/O power supply | 5 V supply for I/O buffers; independent from core VCC to support mixed-voltage operation. |
| TCK, TMS, TDI, TDO | JTAG test interface | Enable boundary-scan testing and in-system programming without external programmers. |
| CLKIN | Global clock input | Single dedicated input drives all macrocell clocks; supports external oscillator or system clock source. |
| RESET | Global asynchronous reset | Active-low signal clears all registers; can be driven by pushbutton or microcontroller GPIO. |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | Enables firmware updates and logic revisions in deployed equipment without removing the device. |
| 5 V tolerant I/Os | Eliminates need for external level translators when interfacing with legacy 5 V peripherals. |
| Low-power 3.3 V core | Reduces active power consumption by ~40% versus 5 V CPLDs while retaining full functionality. |
| Programmable macrocell output polarity | Each macrocell output can be inverted or non-inverted via configuration bit, simplifying logic synthesis. |
| Global clock and reset routing | Dedicated low-skew nets minimize timing uncertainty across all macrocells in high-speed control logic. |

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 |
|---|---|---|---|
| XCR3064XL-10VQ64I | Same 64-pin VQFP package and 3.3 V core, but uses CoolRunner-II architecture with lower static current and higher speed grade. | Better suited for battery-powered portable test gear where standby power matters. | Select if lower quiescent current (<10 µA) and extended temperature range (−40°C to +85°C) are required. |
| XC9536-10VQ64C | 5 V core version with identical pinout and macrocell count, but higher power and no 5 V I/O tolerance. | Requires level-shifting for 5 V peripheral interfaces; limited to legacy designs with 5 V rails only. | Choose only for exact drop-in replacement in pre-existing 5 V systems where redesign is prohibited. |
Compared with XC9536-10VQ64C, the XC9536XL-10VQ64I offers 5 V I/O tolerance and lower power, while XCR3064XL-10VQ64I provides superior static power efficiency and faster timing - making XC9536XL-10VQ64I optimal for cost-sensitive industrial upgrades needing backward compatibility.

Manufacturer
AMD acquired Xilinx in 2022, inheriting its legacy programmable logic portfolio including the XC9500XL family. Xilinx originally developed these CPLDs for high-reliability industrial and aerospace applications.
The XC9500XL product line was engineered for pin-compatible migration from older 5 V CPLDs into 3.3 V systems while preserving logic density, timing predictability, and in-system programmability - targeting industrial retrofits and long-lifecycle equipment.
FAQ
Is XC9536XL-10VQ64I still in production?
No - XC9536XL-10VQ64I is discontinued by AMD/Xilinx but remains available through Aetrix Electronics' authorized legacy inventory and extended-life sourcing channels. We maintain traceable stock with full lot documentation and provide obsolescence mitigation support for ongoing production runs.
What programming tools support XC9536XL-10VQ64I?
Xilinx ISE WebPACK (v14.7 and earlier) fully supports XC9536XL-10VQ64I design entry, simulation, fitting, and JTAG programming. Third-party tools like Lattice Diamond are not compatible. Programming requires a Xilinx Platform Cable USB or equivalent IEEE 1149.1-compliant adapter.
Can XC9536XL-10VQ64I replace XC9536-10VQ64C on the same PCB?
Yes - XC9536XL-10VQ64I is pin-compatible with XC9536-10VQ64C and fits the same VQFP-64 footprint. However, VCC must be changed from 5 V to 3.3 V, and VCCIO remains at 5 V. No PCB modification is needed beyond the power rail update.
Does XC9536XL-10VQ64I support hot-swap or live-insertion?
No - XC9536XL-10VQ64I does not support hot-swap. Power sequencing requirements mandate that VCCIO be applied before or simultaneously with VCC, and both supplies must be stable before JTAG programming or functional operation begins.
What is the maximum operating junction temperature for XC9536XL-10VQ64I?
The maximum operating junction temperature for XC9536XL-10VQ64I is +85°C, as specified in the Xilinx DS056 data sheet. Thermal design must ensure junction temperature stays below this limit under worst-case ambient and power dissipation conditions.
