XC9536XL-10VQG44C: A Reliable, Low-Power CPLD

In embedded system design, sometimes you need just enough programmable logic to manage control tasks, glue logic, or basic I/O interfacing—without the complexity of a full FPGA. That’s exactly where the XC9536XL-10VQG44C, a CPLD (Complex Programmable Logic Device) from Xilinx’s XC9500XL family, shines.

Known for its low power, fast propagation delay, and instant-on performance, this 36-macrocell CPLD is ideal for compact embedded applications in industrial automation, consumer electronics, and communications.

🔍 What is XC9536XL-10VQG44C?

The XC9536XL-10VQG44C is a non-volatile CPLD built using Xilinx’s 0.35 μm low-power CMOS process. It includes 36 logic macrocells, operates at 3.3V I/O (and is 5V tolerant), and is housed in a 44-pin VQFP package, making it well-suited for PCB-constrained designs.

Its low cost and reliable operation make it one of the most commonly used CPLDs in small-scale control applications, providing deterministic behavior and ease of design implementation.
