Product details
Overview
XC9536XL-5VQ44C from AMD (acquired by Xilinx) is a 36-macrocell CPLD in VQFP-44 package, with 5 ns propagation delay, 100 MHz system frequency, and in-system programmable via JTAG. It serves as logic replacement in industrial control I/O modules requiring deterministic timing and reconfigurable glue logic.
For engineers reviewing the XC9536XL-5VQ44C datasheet, pinout, applications, or equivalent options, key selection criteria include macrocell count, tPD, supply voltage range, JTAG compliance, and VQFP-44 thermal profile for legacy board reuse.
Technical Context
The XC9536XL-5VQ44C implements a multi-level PAL architecture with local and global interconnect, supporting up to 36 product terms per macrocell and configurable output polarity. Its JTAG boundary-scan supports IEEE 1149.1 compliance for test and programming.
It operates from 3.3 V ±10%, uses non-volatile EEPROM-based configuration storage, and features slew-rate controlled outputs to reduce EMI in mixed-signal environments.

FAQ
What is the maximum operating frequency of the XC9536XL-5VQ44C?
The XC9536XL-5VQ44C supports a maximum system frequency of 100 MHz, derived from its 5 ns propagation delay specification under worst-case conditions (VCC = 3.0 V, TA = +85°C). This timing applies to internal paths with registered outputs and accounts for setup/hold margins defined in the official Xilinx datasheet DS057.
Does the XC9536XL-5VQ44C require an external configuration PROM?
No, the XC9536XL-5VQ44C does not require an external configuration PROM. It uses on-chip EEPROM to store configuration bitstream, enabling instant-on operation after power-up and eliminating boot-time delays associated with external loading. The XC9536XL-5VQ44C retains its logic design across power cycles without auxiliary memory.
Can the XC9536XL-5VQ44C be reprogrammed in the system?
Yes, the XC9536XL-5VQ44C supports full in-system programmability via its IEEE 1149.1-compliant JTAG port. Reprogramming can be performed without removing the device from the PCB, using standard JTAG adapters. This capability is integral to the XC9536XL-5VQ44C architecture and verified in Xilinx Application Note XAPP161.
What is the I/O voltage compatibility of the XC9536XL-5VQ44C?
The XC9536XL-5VQ44C operates exclusively at 3.3 V ±10% (3.0–3.6 V) and is compatible with LVTTL and LVCMOS33 I/O standards. It does not support 5 V-tolerant inputs or mixed-voltage operation. All I/O pins must be driven within this range to ensure correct logic thresholds and avoid damage to the XC9536XL-5VQ44C core.
Is the XC9536XL-5VQ44C RoHS compliant?
Yes, the XC9536XL-5VQ44C is RoHS compliant and manufactured with lead-free terminations. Per Xilinx documentation, the VQFP-44 package uses matte tin plating over copper leadframe and meets EU Directive 2011/65/EU requirements. This compliance is confirmed in the device's official packaging specification document PS001.
