Product details
Overview
XC95108-20TQ100I from AMD (acquired Xilinx CPLD business) is a 108-macrocell in-system programmable Complex Programmable Logic Device (CPLD) in 100-pin TQFP package, with 20 ns maximum pin-to-pin propagation delay, 5 V supply operation, and IEEE 1149.1 JTAG boundary-scan support. It serves as a glue logic replacement in industrial control I/O expansion modules.
For engineers reviewing the XC95108-20TQ100I datasheet, pinout, applications, or equivalent options, key selection factors include macrocell count, propagation delay grade, JTAG compliance, 5 V tolerance, and TQFP-100 footprint compatibility for legacy board reuse.
Technical Context
The XC95108-20TQ100I implements three function blocks, each containing 36 macrocells with product-term-based logic, shared expanders, and configurable output pins. Each macrocell supports registered or combinatorial output modes with individual clock, reset, set, and output enable controls.
It uses EEPROM-based non-volatile configuration storage, enabling instant-on operation without external configuration PROM. Configuration is performed via IEEE 1149.1 JTAG interface or parallel programming mode using Xilinx WebPACK or iMPACT tools.
Key Specifications

|---|---|
| Macrocell Count | 108 macrocells distributed across three function blocks; enables implementation of medium-complexity synchronous logic such as state machines and bus interfaces. |
| Propagation Delay (tPD) | 20 ns max; ensures timing closure in 50 MHz control-path designs with minimal external buffering. |
| Supply Voltage | 5.0 V ± 10%; compatible with legacy TTL/CMOS systems without level-shifting circuitry. |
| Package | TQFP-100 (14 × 14 mm, 0.5 mm pitch); surface-mount compatible with standard reflow profiles and optical inspection. |
| JTAG Support | IEEE 1149.1 compliant; enables in-circuit programming, boundary-scan testing, and device verification without dedicated programming hardware. |

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 |
|---|---|---|---|
| XCR3128XL-10VQ100I | 128 macrocells, 3.3 V core, 10 ns tPD, CoolRunner-II architecture with lower static current. | Requires level-shifting for 5 V systems; better suited for battery-powered or thermally constrained designs. | Select when migrating to lower-power 3.3 V infrastructure and redesign allows voltage translation. |
| XC9572-15PC84I | 72 macrocells, 84-pin PLCC package, 15 ns tPD, same XC9500 family architecture and toolchain. | Smaller I/O count and footprint; suitable for space-constrained but less complex logic functions. | Select when board layout cannot accommodate TQFP-100 and logic density requirements are ≤72 macrocells. |
Compared with XC95108-20TQ100I, the XCR3128XL-10VQ100I offers higher speed and lower power at the cost of 5 V compatibility, while the XC9572-15PC84I retains full architectural compatibility and tool support but trades macrocell count and package size for legacy PLCC socket reuse.

FAQ
What is the maximum operating frequency supported by XC95108-20TQ100I?
The XC95108-20TQ100I has a 20 ns maximum pin-to-pin propagation delay, enabling reliable operation up to 50 MHz in typical combinatorial paths. Registered logic performance depends on specific routing and feedback paths, but internal register-to-register delays support 40–45 MHz system clocks under standard conditions. The XC95108-20TQ100I does not specify a guaranteed maximum system frequency due to architecture-dependent timing paths.
Does XC95108-20TQ100I require an external configuration PROM?
No. The XC95108-20TQ100I contains on-chip EEPROM for configuration storage, enabling instant-on operation after power-up without external memory. Configuration is retained indefinitely without power, and reprogramming is performed in-system via JTAG or parallel mode. The XC95108-20TQ100I eliminates the need for external PROMs or configuration controllers in standalone CPLD implementations.
Can XC95108-20TQ100I operate with 3.3 V I/O signaling?
No. The XC95108-20TQ100I is a 5 V-only device: its I/O structure is designed for 5 V TTL/CMOS levels, and inputs are 5 V-tolerant but not 3.3 V-compatible for reliable logic thresholds. Driving XC95108-20TQ100I inputs from 3.3 V sources may result in marginal noise margins or incorrect logic interpretation. The XC95108-20TQ100I requires 5 V supply and 5 V signaling for guaranteed operation.
Is XC95108-20TQ100I still in production or subject to obsolescence?
XC95108-20TQ100I is currently available through AMD's legacy product support program with controlled lifetime buy options. While no new silicon fabrication is planned, Aetrix Electronics maintains strategic inventory and offers extended lifecycle coordination. The XC95108-20TQ100I remains actively supported for existing designs requiring long-term supply assurance.
Which programming tools are compatible with XC95108-20TQ100I?
Xilinx ISE WebPACK (v14.7 and earlier) and AMD Vivado (via legacy mode import) support XC95108-20TQ100I programming. Hardware programmers include the Xilinx DLC9, Digilent HS2, and third-party JTAG adapters compliant with IEEE 1149.1. The XC95108-20TQ100I configuration bitstream is generated using ABEL or VHDL synthesis targeting the XC9500 architecture.
