XC9536-10PC44C

Complex Programmable Logic Devices Overview

The XC9536-10PC44C is a Complex Programmable Logic Device (CPLD) from the AMD/Xilinx XC9500XL family, housed in a 44-pin Plastic Quad Flat Package (PQFP). It features 36 macrocells and 800 usable gates organized into two Logic Array Blocks. The device operates at a maximum frequency of 100 MHz with a typical pin-to-pin propagation delay of 10 ns. It supports in-system programming via IEEE 1149.1 JTAG interface and functions within a commercial temperature range of 0°C to +70°C.

Complex Programmable Logic Devices Procurement Notes

Verify the manufacturer designation, as Xilinx was acquired by AMD. Confirm the package type is PQFP-44 and check for end-of-life status, as this specific part number may be discontinued or superseded by newer series variants requiring design review.

Complex Programmable Logic Devices Selection Notes

Select this component when a low-pin-count CPLD with flash-based reprogrammability is required. Ensure the design accommodates the 2.5V core voltage and 5V I/O tolerance if applicable. Compare against the XC9536-7 variant if faster switching speeds are needed, noting the trade-off in power consumption.

Complex Programmable Logic Devices Part Context

This part belongs to the XC9500XL series, an evolution of the original XC9500 line. It retains the same architecture but offers improved performance and lower power consumption through advanced CMOS Flash processes. It serves as a drop-in replacement for many older E²PROM-based CPLDs in existing designs.

Complex Programmable Logic Devices Replacement Considerations

Direct substitutes include other members of the XC9500XL family such as the XC9536-10VQ44C (different package) or the XC9536-10PC44T (industrial temperature grade). Verify pin compatibility and electrical specifications before swapping.
