XC9536XL-5VQ44C

Complex Programmable Logic Devices Overview

The XC9536XL-5VQ44C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family. It features 36 macrocells, 800 usable gates, and 34 I/O pins housed in a VQFP-44 surface-mount package. Operating at a nominal 3.3V supply voltage (range 3.0V to 3.6V), it delivers a maximum propagation delay of 5 ns and a maximum operating frequency of 178 MHz. The device utilizes non-volatile Flash memory for configuration, supports system-in-system programming, and operates within a commercial temperature range of 0°C to +70°C with a typical supply current of 10 mA.

Complex Programmable Logic Devices Feature Summary

• 36 Macrocells with 800 usable gates and 2 Logic Array Blocks (LABs)
• Flash-based non-volatile storage enabling instant-on operation
• High-speed performance: 5 ns max propagation delay and 178 MHz max frequency
• System-in-Programmability (SIP) support via JTAG interface

Complex Programmable Logic Devices Applications

• High-density logic replacement in industrial control systems
• Address decoding and bus buffering in embedded computing
• State machine implementation in communication protocols
• Power-on reset generation and clock management circuits

Complex Programmable Logic Devices Procurement Notes

Verify component authenticity through authorized AMD/Xilinx distributors or certified suppliers. Confirm the specific suffix 'C' denotes the commercial temperature grade (0°C to +70°C). Check for moisture sensitivity labeling as the device is humidity-sensitive. Ensure packaging integrity matches the specified VQFP-44 form factor to prevent pin damage during installation.

Complex Programmable Logic Devices Selection Notes

Select this model when a 3.3V logic family is required with high-speed switching capabilities under 5 ns. Compare against the standard XC9536 if 5V operation is necessary, noting the voltage incompatibility. Consider the XC9536XV series for lower power consumption at 2.5V, accepting reduced speed. Verify that the 34 available I/O pins meet the interface requirements of the target design.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL series, an enhanced version of the original XC9500 CPLD family. It offers improved performance and lower power consumption compared to its predecessors while maintaining pin-compatible options. The XC9536XL represents the entry-level density in the XL line, providing a cost-effective solution for moderate complexity logic designs requiring non-volatile configuration.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements include the XC9536-5VQ44C (5V version, requires voltage level adjustment) and XC9536XL-10VQ44C (slower speed, 10 ns delay). Cross-family substitution with XC9572XL is possible but requires schematic redesign due to different pin counts and I/O configurations.
