XC9536-5PC44C Description

The XC9536-5PC44C is a Complex Programmable Logic Device (CPLD) from AMD's XC9500 series, designed for high-performance logic integration in embedded systems. Housed in a 44-pin PLCC (Plastic Leaded Chip Carrier) package, this 5V-operated device features 36 macrocells and 800 equivalent gates, delivering a maximum propagation delay of 5 ns. Its in-system programmability (ISP) supports a minimum of 10,000 program/erase cycles, enabling flexible field updates. With 34 I/O pins and 2 logic blocks, it balances density and speed for mid-range applications. Though marked obsolete, it remains relevant in legacy designs due to its reliability and deterministic timing.

XC9536-5PC44C Features

• High-Speed Performance: 5 ns pin-to-pin delay ensures rapid signal processing.
• In-System Programmability: Reconfigurable via JTAG, reducing development cycles.
• Robust I/O Capacity: 34 I/O pins support versatile interfacing.
• Wide Voltage Range: 4.75V–5.25V internal supply tolerance for stable operation.
• Surface-Mount Packaging: 44-PLCC suits space-constrained PCB designs.
