XC9536-5VQ44C

Complex Programmable Logic Devices Overview

The XC9536-5VQ44C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500 family, housed in a 44-pin VQFP package. It features 36 macrocells and 800 usable gates organized into two Logic Array Blocks (LABs). The device operates at a maximum frequency of 125 MHz with a typical propagation delay of 7.5 ns. It supports in-system programmability via Flash memory technology and functions within a voltage range of 2.37 V to 2.62 V, consuming approximately 7 mA of operating current across an industrial temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Feature Summary

• Flash-based non-volatile configuration allowing for in-system programming without externalEPROM.
• High-speed performance with a maximum operating frequency of 125 MHz and 7.5 ns propagation delay.
• Compact architecture integrating 36 macrocells and 800 gates within a 44-pin VQFP surface-mount package.

Complex Programmable Logic Devices Applications

• General-purpose digital logic replacement for discrete gate arrays.
• Address decoding and bus interfacing in embedded systems.
• State machine implementation for control logic applications.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '5VQ44C' against official AMD/Xilinx documentation to confirm pinout compatibility and electrical specifications. Ensure that the procurement source provides valid traceability for the component's manufacturing origin and storage history, as moisture sensitivity levels may apply to the VQFP package.

Complex Programmable Logic Devices Selection Notes

Select this component when a low-pin-count CPLD with Flash memory is required for designs needing 36 macrocells. Compare the 7.5 ns delay against system timing requirements. Consider the XC9536XL series if a 3.3V supply voltage is preferred over the standard 5V operation defined for this part number.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500 family, which established industry standards for high-density, easy-to-use CPLDs. The XC9536 variant specifically targets applications requiring moderate logic density in small form factors, bridging the gap between simple PLDs and larger FPGA architectures.

Complex Programmable Logic Devices Replacement Considerations

The XC9536XL-5VQ44C offers similar logic density but operates at 3.3V. Verify voltage level compatibility before substitution. Other family members like the XC9572 provide higher macrocell counts but require different pin configurations.
