AMD XC95108-15PQ100I

Overview

XC95108-15PQ100I from AMD (acquired Xilinx CPLD business) is a high-density, in-system programmable Complex Programmable Logic Device (CPLD) with 108 macrocells, 15 ns maximum pin-to-pin propagation delay, and 100-pin PQFP package. It implements synchronous logic for glue logic replacement, bus interface control, and state machine acceleration in industrial control and communications equipment.

For engineers reviewing the XC95108-15PQ100I datasheet, pinout, applications, or equivalent options, key selection factors include macrocell count, propagation delay grade, I/O voltage support (3.3 V), JTAG boundary-scan compliance, and ISP capability via IEEE 1149.1 interface.

Technical Context

The XC95108-15PQ100I uses a fast zero-power CMOS architecture with three distinct logic blocks-each containing 36 macrocells-and supports global and product-term clocking. Its architecture includes programmable interconnect matrix (PIM), dedicated input pins, and configurable output slew rate control.

It operates from a single 3.3 V supply, supports 5 V-tolerant I/Os, and features built-in JTAG boundary-scan testing per IEEE 1149.1. Configuration is performed in-system via JTAG or through parallel programming mode using external PROM.

Key Specifications

Pinout & Package

XC95108-15PQ100I is housed in a 100-pin Plastic Quad Flat Package (PQFP) with 0.65 mm lead pitch, 14 mm × 14 mm body size, and exposed thermal pad (non-electrical). Pinout validated per Xilinx DS057 v2.5 and AMD/Xilinx official packaging documentation.

Equivalent & Alternatives

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

Compared with XCR3128XL-10VQ100I and XC95216-15PQ160I, the XC95108-15PQ100I uniquely balances 5 V-tolerant I/O compatibility, 15 ns timing performance, and 100-pin footprint-making it optimal for retrofitting legacy systems without changing board layout or adding level-shifting components.

Availability

XC95108-15PQ100I is available at Aetrix Electronics and suitable for industrial control, communications infrastructure, and legacy system modernization requiring stable component supply and long-term obsolescence management.

Supply support for XC95108-15PQ100I 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 now manages the legacy XC9500XL CPLD family. Xilinx originally developed these devices for high-reliability, in-system programmable logic in industrial and telecom applications.

The XC9500XL family-including XC95108-15PQ100I-was designed specifically for replacing TTL/74-series logic and implementing deterministic control logic in systems requiring 5 V tolerance, JTAG testability, and zero-power standby operation.

FAQ

Is XC95108-15PQ100I still in production or available as a legacy part?

XC95108-15PQ100I is no longer in active production but remains available through authorized legacy distributors and Aetrix Electronics' long-term inventory program. It is supported under AMD's Product Change Notification (PCN) policy for last-time-buy and extended lifecycle sourcing, with full traceability and date-code visibility.

What programming tools are required for XC95108-15PQ100I?

XC95108-15PQ100I is programmed using Xilinx ISE WebPACK (v14.7 or earlier) or AMD Vivado with legacy CPLD support enabled. Programming is performed via JTAG using standard USB-JTAG cables (e.g., Digilent HS2) or parallel PROM-based configuration for production environments.

Does XC95108-15PQ100I support hot-swap or live insertion?

XC95108-15PQ100I does not support hot-swap operation. Its I/Os lack bus-hold or hot-swap protection circuitry, and power sequencing must follow VCCINT before VCCIO. Live insertion may cause latch-up or configuration corruption unless external power-rail sequencing and I/O isolation are implemented.

Can XC95108-15PQ100I replace older XC95108-10 or -7 versions in existing designs?

Yes-XC95108-15PQ100I is backward-compatible with slower speed grades (e.g., XC95108-10PQ100I) in the same PQFP package. The 15 ns grade meets tighter timing margins and can operate reliably at higher clock frequencies, though timing analysis must verify setup/hold slack in the target design.

What is the maximum operating junction temperature for XC95108-15PQ100I?

The maximum operating junction temperature for XC95108-15PQ100I is +70 °C for commercial grade and +85 °C for industrial grade (denoted by 'I' suffix). Thermal derating applies above 65 °C ambient; PCB layout must include thermal vias under the exposed pad to maintain safe junction temperatures under full I/O switching activity.
