XC95288XL-10PQG208I

Complex Programmable Logic Devices Overview

The XC95288XL-10PQG208I is a Complex Programmable Logic Device (CPLD) belonging to the AMD XC9500XL family. It features 288 macrocells and approximately 6,400 usable gates within an industrial temperature range of -40°C to +85°C. The device utilizes a FastFLASH non-volatile memory technology, allowing for infinite reprogramming without external configuration devices. Key electrical specifications include a maximum propagation delay of 10 ns and an internal supply voltage range of 3.0V to 3.6V. It supports system-in-system programming with at least 10,000 erase/program cycles and offers 5V-tolerant I/Os compatible with various logic families.

Complex Programmable Logic Devices Feature Summary

• FastFLASH Non-Volatile Technology: Eliminates the need for external configuration PROMs and supports infinite power-up cycles.
• High Performance: Delivers a maximum propagation delay of 10 ns with up to 90 MHz operating frequency.
• 5V Tolerant I/Os: All input/output pins are 5V tolerant, enabling direct interfacing with 5V TTL and CMOS logic.
• System In-System Programming: Supports JTAG interface for in-circuit programming and IEEE 1149.1 boundary scan testing.

Complex Programmable Logic Devices Applications

• Bus arbitration and protocol conversion in embedded systems.
• Address decoding and control logic generation.
• State machine implementation requiring deterministic timing.
• Replacement for legacy GALs and PALs in industrial controllers.

Complex Programmable Logic Devices Procurement Notes

This component is identified as obsolete or end-of-life. Verification of current stock availability from authorized distributors is required before procurement planning. Alternative components from the same family or successor series should be evaluated for long-term supply chain stability.

Complex Programmable Logic Devices Selection Notes

Select this model when deterministic latency is critical for control logic applications. The 10 ns speed grade suits moderate-speed designs. Ensure the design requires 288 macrocells and fits within the 208-pin PQFP package constraints. Verify that the 3.3V core voltage and 5V I/O tolerance match the system's power and interface requirements.

Complex Programmable Logic Devices Part Context

The XC95288XL-10PQG208I is part of the XC9500XL family, which bridges the gap between simple PLDs and complex FPGAs. Unlike FPGAs, it uses a fixed interconnect structure, providing predictable signal delays. This makes it suitable for applications where timing predictability is more important than massive parallel processing capacity.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may not exist due to the obsolescence status. Evaluate other XC9500XL variants with different speed grades or packages if available. Consider modern CPLD alternatives from AMD or other manufacturers that offer similar macrocell counts and Flash-based architecture.
