Product details
Overview
XC95108-20PQ100I 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 20 ns maximum pin-to-pin propagation delay, 5.0 V supply operation, and support for IEEE Std 1149.1 JTAG boundary-scan testing. It is used in legacy industrial control logic replacement and FPGA configuration glue logic.
For engineers reviewing the XC95108-20PQ100I datasheet, pinout, applications, or equivalent options, key selection considerations include macrocell count, propagation delay grade, 5V I/O compatibility, JTAG test support, and legacy design migration path from older XC9500-series devices.
Technical Context
This CPLD implements a multi-array architecture with three function blocks interconnected via a global routing pool, enabling flexible logic partitioning and high-speed signal routing. Each macrocell supports sum-of-products logic, registered or combinatorial output, and individual product-term sharing across adjacent macrocells.
Configuration is performed via JTAG interface using IEEE 1149.1 protocol; no external configuration memory is required. The device retains logic state after power cycling due to on-chip non-volatile EEPROM cells programmed at 5.0 V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocell Count | 108 macrocells provide sufficient logic density for medium-complexity glue logic and state-machine implementation. |
| Max Propagation Delay | 20 ns ensures timing-critical control paths meet sub-25 MHz synchronous operation requirements. |
| Supply Voltage | 5.0 V ±10% operation enables direct interfacing with legacy TTL/CMOS systems without level-shifting. |
| JTAG Support | IEEE 1149.1 compliance allows boundary-scan testing and in-system programming without dedicated programming hardware. |
| Non-volatile Memory | On-chip EEPROM retains configuration indefinitely without external memory or boot ROM. |
| I/O Pins | 84 user I/O pins support bidirectional signals with configurable slew rate and drive strength. |
Pinout & Package
XC95108-20PQ100I is housed in a 100-lead Plastic Quad Flat Pack (PQFP) with 0.65 mm lead pitch and 14 × 14 mm body size. Pin 1 is marked by a corner notch or dot; power (VCC = Pin 86, GND = Pins 14, 27, 40, 53, 66, 79, 92) and JTAG (TCK, TMS, TDI, TDO, TST) pins are distributed per Xilinx XC9500 family layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| TCK | JTAG Clock Input | Synchronizes boundary-scan register shifts; requires clean 5 V CMOS-level clock signal. |
| TMS | JTAG Mode Select Input | Controls TAP controller state transitions during programming and test operations. |
| TDI | JTAG Data Input | Serial input for configuration bitstream and test data into boundary-scan chain. |
| TDO | JTAG Data Output | Serial output for readback of device ID, status, or test response data. |
| TST | Test Enable Input | Activates boundary-scan circuitry; pulled high internally when not externally driven. |
| VCC | Core & I/O Supply | 5.0 V power for logic array, macrocells, and I/O buffers; decoupling required at each VCC pin. |
| GND | Ground Reference | Common return path for all internal logic and I/O; multiple pins reduce ground bounce. |
Key Features
| Feature | Design Value |
|---|---|
| In-System Programmability | Enables field firmware updates and logic revisions without device removal or socket programming. |
| 5 V Tolerant I/O | Supports direct connection to legacy 5 V microcontrollers, FPGAs, and peripheral ICs without voltage translation. |
| Global Routing Pool | Provides low-skew interconnect between function blocks, improving timing predictability in multi-block designs. |
| Individual Macrocell Control | Each macrocell can be configured as registered or combinatorial output with independent clock enable and reset. |
| Power-On Reset Circuit | Ensures deterministic initial state on power-up, eliminating need for external POR components. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based glue logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XC95144-20PQ100I | 144 macrocells, same 20 ns speed grade and PQFP-100 package; higher logic density but identical pinout and voltage specs. | Supports larger state machines and more complex bus arbitration logic without PCB redesign. | Select when additional macrocells are needed for expanded functionality while retaining footprint and toolchain compatibility. |
| XC9572-20PC44I | 72 macrocells in 44-pin PLCC package; lower I/O count, smaller footprint, and reduced power consumption. | Suitable for space-constrained designs where full 108-macrocell capacity is unnecessary. | Choose for cost-sensitive or compact applications where logic density and I/O count are scaled down. |
Compared with XC95108-20PQ100I, XC95144-20PQ100I offers headroom for future logic expansion within the same PCB layout, while XC9572-20PC44I trades density and I/O for lower cost and smaller area-both require separate evaluation for timing closure and resource utilization in target designs.

FAQ
What is the maximum operating frequency supported by XC95108-20PQ100I?
The XC95108-20PQ100I has a 20 ns maximum pin-to-pin propagation delay, supporting system clock frequencies up to approximately 25 MHz in simple combinatorial paths. Registered logic performance depends on internal routing and macrocell placement; actual achievable frequency must be verified in place-and-route reports generated by Xilinx Foundation or WebPACK tools for XC95108-20PQ100I.
Does XC95108-20PQ100I require an external configuration PROM?
No, XC95108-20PQ100I does not require an external configuration PROM. It contains on-chip EEPROM that retains the programmed logic configuration indefinitely after power cycling. Configuration is loaded automatically on power-up, making XC95108-20PQ100I a true single-chip solution for non-volatile logic applications.
Can XC95108-20PQ100I be reprogrammed in-system?
Yes, XC95108-20PQ100I supports full in-system programmability via its IEEE 1149.1 JTAG interface. This allows field updates, logic revisions, and debugging without removing the device from the PCB. Reprogramming requires only a JTAG cable and compatible software such as Xilinx IMPACT, and does not affect the operational state of surrounding circuitry during XC95108-20PQ100I configuration.
What development tools are compatible with XC95108-20PQ100I?
XC95108-20PQ100I is supported by Xilinx Foundation Series and WebPACK software (legacy versions), which provide schematic capture, ABEL/VHDL synthesis, place-and-route, and JTAG programming. AMD maintains archived tool access for XC9500 devices; newer Vivado tools do not support XC95108-20PQ100I. Device-specific libraries and timing models for XC95108-20PQ100I remain available through AMD's legacy support portal.
Is XC95108-20PQ100I RoHS compliant?
XC95108-20PQ100I was originally manufactured as a non-RoHS part (lead-containing solder finish). AMD's current legacy support documentation confirms no RoHS-compliant variant was released for the PQFP-100 package. Customers requiring RoHS compliance must evaluate form-fit-function alternatives or implement board-level mitigation strategies when using XC95108-20PQ100I.
