XC9536-15PC44I

Complex Programmable Logic Devices Overview

The AMD XC9536-15PC44I is a Complex Programmable Logic Device (CPLD) belonging to the XC9500XL family. It features 36 macrocells and 800 usable gates within two logic array blocks, supporting up to 34 user I/O pins. The device operates at a maximum frequency of 64.5 MHz with a typical propagation delay of 15 ns. It utilizes Flash memory technology for non-volatile configuration, allowing in-system programmability. The component is housed in a 44-pin PLCC package and supports a supply voltage range of 3.0 V to 3.6 V.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'I' indicates industrial temperature rating (-40°C to +85°C). Confirm package type is PLCC-44. Check current availability status as older CPLD families may have limited stock or end-of-life implications from AMD/Xilinx distributors.

Complex Programmable Logic Devices Selection Notes

Select this part when 36 macrocells are sufficient for the design logic. Ensure the system requires 3.3V operation. Compare against XC9536-10 if faster switching speeds (10 ns delay) are required, noting that lower delay numbers indicate higher speed grades.

Complex Programmable Logic Devices Part Context

This component is part of the XC9500XL series, an evolution of the original XC9500 line. It retains the same logical structure but offers improved performance and lower power consumption through advanced Flash process technology compared to its EEPROM-based predecessors.

Complex Programmable Logic Devices Replacement Considerations

Direct functional substitutes include other parts within the XC9500XL family such as XC9536-10PC44I for higher speed requirements. Cross-family replacements like the XC9572 offer more macrocells but require pinout compatibility checks.
