AMD XC95108-15PQ100C

Overview

XC95108-15PQ100C from AMD (acquired Xilinx CPLD business) is a 108-macrocell in-system programmable Complex Programmable Logic Device (CPLD) in a 100-pin PQFP package, with 15 ns maximum pin-to-pin delay, 3.3 V supply voltage, and support for IEEE 1149.1 JTAG boundary-scan testing. It targets glue logic replacement and control logic in industrial I/O modules.

For engineers reviewing the XC95108-15PQ100C datasheet, pinout, applications, or equivalent options, key selection factors include propagation delay, macrocell count, JTAG compliance, I/O voltage tolerance, and in-system programmability without requiring UV erasure.

Technical Context

The XC95108-15PQ100C implements a multi-level PAL architecture with three macrocell types-combinatorial, registered, and feedback-enabling flexible logic synthesis. Each macrocell includes a product-term allocator, configurable flip-flop (with synchronous/asynchronous reset/set), and programmable output polarity.

It uses a global routing pool with dedicated high-fanout clock, output enable, and reset lines, supporting up to 80 user I/O pins with 2.5 V/3.3 V mixed-voltage operation and hot-swap compliant inputs. Configuration is performed via JTAG or ISP using Xilinx WebPACK or iMPACT tools.

Key Specifications

Pinout & Package

XC95108-15PQ100C is housed in a 100-lead Plastic Quad Flat Pack (PQFP) with 0.65 mm lead pitch, 14 mm × 20 mm body size, and standard JEDEC MO-118 footprint.

Equivalent & Alternatives

The following parts are listed as comparable options for similar CPLD-based control logic applications.

Compared with XC95108-15PQ100C, the XCR3128XL-10VQ100C offers faster timing and lower power at the cost of older design tool deprecation, while the XC95216-15PQ160C extends logic capacity within the same XC9500 family ecosystem-neither is pin-compatible, but both share functional equivalence for control-intensive logic synthesis.

Availability

XC95108-15PQ100C is available at Aetrix Electronics and suitable for industrial automation, test equipment, and medical device manufacturing requiring stable component supply and long-term obsolescence management.

Supply support for XC95108-15PQ100C includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

Manufacturer

AMD acquired Xilinx in 2022 and maintains legacy CPLD product lines including the XC9500 family for industrial and aerospace customers requiring long-lifecycle support.

The XC9500 series was designed for deterministic, low-latency control logic in mission-critical systems where FPGA configurability introduces unacceptable startup delay or resource fragmentation.

FAQ

What is the maximum operating frequency supported by XC95108-15PQ100C?

The XC95108-15PQ100C has a 15 ns maximum pin-to-pin propagation delay, enabling reliable operation at up to 66 MHz in simple combinatorial paths. Registered logic performance depends on internal routing and macrocell placement, but typical system clock frequencies range from 33 MHz to 50 MHz under real-world timing constraints.

Does XC95108-15PQ100C support in-system programming via JTAG?

Yes, XC95108-15PQ100C fully supports IEEE 1149.1 JTAG-based in-system programming (ISP). This allows full configuration bitstream loading, erase, and verify operations while the device remains soldered on the target board using standard JTAG adapters and Xilinx iMPACT software.

Can XC95108-15PQ100C operate with 5 V-tolerant I/Os?

No, XC95108-15PQ100C I/O pins are not 5 V tolerant. They operate at 3.3 V with input thresholds compatible with LVTTL and LVCMOS standards. External level shifters are required for interfacing with true 5 V logic families.

What development tools are compatible with XC95108-15PQ100C?

XC95108-15PQ100C is supported by Xilinx WebPACK ISE 14.7 and earlier versions. Synthesis, fitting, and JTAG programming are fully functional in this environment. AMD does not support newer Vivado tools for this legacy CPLD family.

Is XC95108-15PQ100C RoHS compliant?

Yes, XC95108-15PQ100C is RoHS 6/6 compliant and lead-free. The PQFP package uses matte tin lead finish, and the device meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) requirements for standard SMT assembly processes.
