XC9536XL-5PCG44C

Complex Programmable Logic Devices Overview

The XC9536XL-5PCG44C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family. It features 36 macrocells and 800 usable logic gates within a 44-pin Plastic Chip Grid Array (PCGA) package. The device operates at a maximum system frequency of 178 MHz with a pin-to-pin delay of 5 ns. It supports in-system programming via JTAG and offers voltage compatibility for both 5V and 3.3V I/O interfaces, ensuring robust performance in mixed-voltage designs.

Complex Programmable Logic Devices Feature Summary

• High-speed performance: 5 ns max delay and 178 MHz system frequency
• Compact architecture: 36 macrocells and 800 usable gates
• In-system programmability: Supports JTAG interface for flexible updates
• Voltage flexibility: Compatible with 5V and 3.3V I/O standards

Complex Programmable Logic Devices Applications

• Logic replacement for legacy TTL/CMOS circuits
• Address decoding and bus arbitration
• State machine implementation
• Clock generation and synchronization

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'PCG44C' to confirm the plastic chip grid array package type and commercial temperature range. Ensure the ordering code matches the required speed grade (-5) for 5 ns timing specifications. Confirm that the supplier provides original manufacturer documentation or traceability records to guarantee component authenticity.

Complex Programmable Logic Devices Selection Notes

Select this model when a small CPLD with high-speed 5 ns performance is required in a compact PCGA footprint. Compare against the XC9536-5 variant if non-volatile Flash memory is not needed, as the XL series includes Flash technology. Consider the -10 speed grade if lower power consumption is prioritized over maximum switching speed.

Complex Programmable Logic Devices Part Context

This component belongs to the XC9500XL series, which introduced Flash-based non-volatile configuration to the established XC9500 family. The XC9536XL represents the entry-level density option within this series, providing a cost-effective solution for low-pin-count applications requiring reprogrammability without external configuration devices.

Complex Programmable Logic Devices Replacement Considerations

Direct functional equivalents include the XC9536-5PCG44C, though it lacks Flash memory. Other compatible parts in the same package are XC9536XL-10PCG44I for relaxed timing requirements. Verify pinout compatibility before substituting with higher-density models like the XC9572XL.
