XC9536XL-7VQ44I

Complex Programmable Logic Devices Overview

The XC9536XL-7VQ44I is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, housed in a 44-pin VQFP surface-mount package. It features 36 macrocells and 800 usable logic gates within two Logic Array Blocks (LABs). The device supports 34 I/O pins and operates on a single 3.3V supply voltage with a maximum operating frequency of 178 MHz. Key electrical parameters include a maximum propagation delay of 7 ns, an operating temperature range of 0°C to +70°C, and a typical supply current of 10 mA. It utilizes non-volatile Flash memory for configuration retention.

• Interface translation between different voltage domains or protocols.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature grade (0°C to +70°C) as per official datasheets. Confirm availability status with authorized distributors, as legacy CPLD lines may have limited stock or end-of-life implications. Ensure packaging matches the VQFP-44 specification for PCB footprint compatibility.

Complex Programmable Logic Devices Selection Notes

Select this model when 36 macrocells are sufficient for the design complexity. Compare against the XC9536XL-5 variant if faster switching speeds (5 ns delay) are required, noting potential differences in power consumption. Ensure the design fits within the 34 I/O limit and that the 3.3V I/O levels match the target system requirements without additional level shifting.

Complex Programmable Logic Devices Part Context

This component belongs to the XC9500XL series, which succeeded the original XC9500 family by integrating Flash memory to remove the need for external configuration devices. The XC9536XL represents the entry-level density in this high-performance CPLD line, offering a balance of logic capacity and pin count for compact designs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-compatible replacements within the same package include other speed grades of the XC9536XL series, such as the XC9536XL-5VQ44C/I. For higher density needs, consider the XC9572XL series, though pin counts and macrocell configurations will differ significantly.
