XC95216-20PQ160C

Complex Programmable Logic Devices Overview

The XC95216-20PQ160C is a high-performance Complex Programmable Logic Device (CPLD) from AMD's XC9500 family, housed in a 160-pin PQFP package. It features 21,600 usable system gates and supports up to 1,840 I/O pins. The device operates with a maximum propagation delay of 20 ns and utilizes non-volatile Flash memory technology for instant-on functionality without external configuration devices. Designed for robust digital logic applications, it offers flexible macrocell architecture with global and dedicated interconnects.

Complex Programmable Logic Devices Procurement Notes

Verify the specific suffix 'C' indicates commercial temperature range (-0°C to +70°C) and 'PQ160' denotes the plastic quad flatpack package. Confirm that the part number corresponds to the standard XC95216 variant rather than a specialized industrial or automotive grade version. Ensure compatibility with existing JTAG programming cables and software tools for Flash-based CPLDs.

Complex Programmable Logic Devices Selection Notes

Select this component when non-volatile configuration is required to eliminate external PROMs. The 20 ns speed grade suits moderate-frequency digital logic applications. Consider the 160-pin package size for board space constraints. Verify that the 3.3V or 5V I/O voltage requirements align with the target system design, as XC9500 devices often support mixed-voltage I/O banks.

Complex Programmable Logic Devices Part Context

The XC9500 series represents AMD's (formerly Xilinx) second-generation Flash CPLD architecture, succeeding the NVSRAM-based XC9500XL. These devices bridge the gap between simple gate arrays and complex FPGAs, offering deterministic timing and low standby power. The XC95216 provides a mid-range density option within this lineage, widely adopted in legacy and cost-sensitive industrial designs.

Complex Programmable Logic Devices Replacement Considerations

Direct pin-to-pin replacements may include other XC95216 variants with different speed grades (e.g., -15, -25) or packages. For higher density needs, consider XC95360 or XC95720 models if pin count allows. Note that newer Flash CPLD families may offer improved performance but require verification of electrical compatibility.
