XC95288XL-10PQG208C

Complex Programmable Logic Devices Overview

The XC95288XL-10PQG208C is a Complex Programmable Logic Device (CPLD) belonging to the AMD XC9500XL family. It features 288 macrocells, 16 logic blocks, and approximately 6400 usable gates. The device operates with a core voltage of 3V to 3.6V and supports 5V-tolerant I/Os. It utilizes FastFLASH technology for non-volatile configuration, eliminating the need for external memory. The maximum propagation delay is specified at 10 ns. The component is housed in a 208-pin Plastic Quad Flat Package (PQFP) and is rated for an operating temperature range of 0°C to 70°C.

Complex Programmable Logic Devices Feature Summary

• FastFLASH non-volatile architecture allows infinite reprogramming without external configuration memory.
• System In-Programmability (SIP) via JTAG interface supports IEEE 1149.1 boundary scan.
• 5V tolerant I/Os enable direct interfacing with legacy 5V logic systems.
• Deterministic fixed-delay interconnect structure ensures predictable timing performance.

Complex Programmable Logic Devices Applications

• Bus arbitration and protocol conversion in mixed-voltage digital systems.
• Address decoding and control logic generation for memory interfaces.
• State machine implementation requiring deterministic timing constraints.
• Replacement of discrete TTL/CMOS logic in industrial control panels.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix '10' corresponds to the 10 ns speed grade when sourcing replacements. Confirm package integrity for the 208-PQFP form factor. Check manufacturer documentation for End-of-Life (EOL) status, as older CPLD families may have limited production availability. Ensure JTAG programming tools are compatible with the XC9500XL series architecture.

Complex Programmable Logic Devices Selection Notes

Select this model when design requirements specify exactly 288 macrocells and 168 available I/O pins. The 10 ns speed grade suits applications with moderate clock frequencies up to approximately 90 MHz. Choose the PQG208 package if board space accommodates a 28x28 mm footprint. Verify that the 3.3V core voltage aligns with the system power distribution network.

Complex Programmable Logic Devices Part Context

This component is part of the XC9500XL series, which succeeded the original XC9500 line by integrating Flash memory for instant-on capability. The XC95288 variant represents a high-density option within this family, offering significant logic capacity for its era. It bridges the gap between simple PLDs and complex FPGAs, providing a cost-effective solution for fixed-function logic control.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may be unavailable due to EOL status. Consider equivalent devices from the same XC9500XL family with different speed grades or packages. Cross-family migration to newer CPLD architectures requires verification of macrocell compatibility and I/O voltage levels.
