Product details
Overview
XC9536XL-7VQ64C from AMD (acquired by Xilinx) is a 36-macrocell CPLD in VQFP-64 package, with 7 ns propagation delay, 5 V tolerant I/O, and in-system programmable via JTAG. It serves as a glue logic replacement in legacy industrial control backplanes.
For engineers reviewing the XC9536XL-7VQ64C datasheet, pinout, applications, or equivalent options, key selection criteria include macrocell count, I/O voltage tolerance, programming interface compatibility, and timing grade for retrofitted control logic.
Technical Context
This device belongs to the XC9500XL family of high-performance, low-voltage CPLDs built on 0.35 µm CMOS technology. It implements complex combinational and sequential logic using sum-of-products architecture with local feedback paths and global clocking resources.
The XC9536XL-7VQ64C supports IEEE 1149.1 JTAG boundary-scan testing and in-system programming at 3.3 V core voltage while maintaining 5 V-tolerant I/O pins. Its architecture includes four function blocks, each with nine macrocells and dedicated product-term sharing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocell Count | 36 macrocells - provides sufficient logic density for medium-complexity glue logic replacement tasks |
| Propagation Delay | 7 ns - enables reliable operation up to ~100 MHz system clock domains in combinatorial paths |
| I/O Voltage Tolerance | 5 V tolerant - allows direct interfacing with legacy 5 V TTL/CMOS buses without level shifters |
| Core Supply Voltage | 3.3 V ± 0.3 V - requires stable low-noise 3.3 V rail; not compatible with 5 V core operation |
| JTAG Support | IEEE 1149.1 compliant - enables boundary-scan testing and in-system programming without external programmers |
| Function Blocks | 4 blocks × 9 macrocells - defines internal routing granularity and logic partitioning capability |
Pinout & Package
VQFP-64 (Very Thin Quad Flat Package, 64-pin, 10 mm × 10 mm, 0.5 mm pitch) with exposed thermal pad. Pin 1 marked by dot or notch orientation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 13, 25, 37, 49, 61) | Ground reference | Multiple distributed GND pins reduce ground bounce and improve signal integrity in high-speed logic transitions |
| VCCINT (Pins 2, 14, 26, 38, 50, 62) | Core power supply | Supplies 3.3 V to internal logic; decoupling required within 10 mm of each pin |
| VCCIO (Pins 3, 15, 27, 39, 51, 63) | I/O power supply | Configures I/O voltage level; supports 3.3 V or 5 V operation depending on external connection |
| TCK, TMS, TDI, TDO | JTAG test access port | Enables IEEE 1149.1 boundary-scan and ISP; must be pulled appropriately for normal operation |
| PROGRAMN | Asynchronous reset input | Active-low signal that clears all macrocell registers and resets configuration state |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | Eliminates need for socketed UV-erasable PLDs; enables field firmware updates and design iteration without board rework |
| 5 V-tolerant I/Os | Preserves compatibility with legacy 5 V peripheral interfaces while operating on modern 3.3 V core rails |
| Fast zero-power operation | Static power consumption < 10 µA at 25 °C - suitable for battery-backed or low-quiescent systems |
| Programmable slew rate control | Reduces EMI and overshoot on critical I/O lines by limiting edge rates per pin group |
| Global and local clock networks | Supports synchronous logic with multiple clock domains and registered outputs across function blocks |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based glue logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3032XL-7VQ64C | Same pinout, identical VQFP-64 package, but uses 2.5 V core supply and lacks 5 V I/O tolerance | Requires level-shifting for 5 V bus interfacing; unsuitable for direct drop-in replacement in legacy 5 V systems | Select only if system already uses 2.5 V core and 3.3 V I/O infrastructure |
| XC9572XL-7VQ64C | Same family, same 3.3 V core and 5 V I/O tolerance, but doubles macrocell count to 72 | Higher logic density supports more complex state machines or wider bus interfaces without additional devices | Choose when future-proofing for added functionality or consolidating multiple XC9536XL devices |
Compared with XC9536XL-7VQ64C, XCR3032XL-7VQ64C reduces power but sacrifices 5 V compatibility, while XC9572XL-7VQ64C offers scalable logic capacity within identical voltage and packaging constraints.

The XC9500XL product line targets long-lifecycle, maintenance-intensive systems where programmable logic must retain 5 V interface compatibility while reducing static power versus earlier XC9500 devices.
FAQ
What is the maximum operating frequency supported by the XC9536XL-7VQ64C?
The XC9536XL-7VQ64C has a 7 ns propagation delay specification, supporting reliable operation up to approximately 100 MHz in purely combinatorial paths. Registered output performance depends on clock-to-output timing and setup/hold margins, typically enabling synchronous designs up to 80 MHz under standard loading conditions. The actual achievable frequency in a given design depends on routing, fanout, and I/O loading.
Does the XC9536XL-7VQ64C require external configuration memory?
No, the XC9536XL-7VQ64C contains non-volatile EEPROM-based configuration memory and powers up fully operational without external PROM or flash. Configuration is retained indefinitely after programming, and the device does not rely on external memory for initialization. This eliminates boot-time delays and external component dependencies present in SRAM-based FPGAs.
Can the XC9536XL-7VQ64C be reprogrammed in the field without removing it from the PCB?
Yes, the XC9536XL-7VQ64C supports full in-system programming (ISP) via its IEEE 1149.1 JTAG interface. Reprogramming can be performed live on powered boards using standard JTAG adapters, enabling firmware updates, bug fixes, and logic revisions without physical access to the device or board disassembly.
Is the XC9536XL-7VQ64C RoHS compliant?
Yes, the XC9536XL-7VQ64C is RoHS-6 compliant (lead-free, mercury-free, cadmium-free, hexavalent chromium-free, PBB-free, PBDE-free) and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements. Lead-free reflow profiles and halogen-free packaging are specified in the official Xilinx documentation for this part number.
What development tools support the XC9536XL-7VQ64C?
Xilinx ISE WebPACK (v14.7 and earlier) fully supports synthesis, place-and-route, and programming of the XC9536XL-7VQ64C. Third-party tools such as HDL Designer and older versions of Synplify also generate compatible JEDEC files. Programming is verified using Xilinx IMPACT or compatible JTAG utilities like UrJTAG.
