Product details
Overview
XC95108-20TQ100C from AMD (acquired Xilinx CPLD division) is a 108-macrocell in-system programmable Complex Programmable Logic Device (CPLD) in 100-pin TQFP package, with 20 ns maximum pin-to-pin delay, 5 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 XC95108-20TQ100C datasheet, pinout, applications, or equivalent options, key selection factors include propagation delay budget, I/O voltage compatibility, macrocell count for state machine depth, and JTAG debug integration capability.
Technical Context
The XC95108-20TQ100C implements a multi-array architecture with three function blocks, each containing 36 macrocells with configurable product-term-based logic and registered outputs. Each macrocell supports combinational or registered mode, asynchronous reset, synchronous preset, and clock enable.
It uses EEPROM-based non-volatile configuration storage, enabling instant-on operation without external configuration PROM. The device supports in-system programming via JTAG interface at 5 V, with up to 10,000 program/erase cycles and 20-year data retention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocell Count | 108 macrocells distributed across three function blocks; determines maximum combinational logic depth and registered state machine size. |
| Max Pin-to-Pin Delay | 20 ns at 5 V; defines worst-case timing path for synchronous logic interfacing with microcontrollers or memory. |
| Supply Voltage | 5.0 V ± 10%; requires standard TTL-compatible power rail, no level-shifting needed for legacy 5 V systems. |
| I/O Pins | 84 user I/O pins with 3.3 V/5 V tolerant inputs; supports mixed-voltage board interfaces without external translators. |
| JTAG Support | IEEE 1149.1 compliant; enables boundary-scan testing, in-system programming, and device verification without test fixtures. |
| Configuration Memory | EEPROM-based non-volatile storage; eliminates boot-time configuration delay and external PROM dependency. |
Pinout & Package
XC95108-20TQ100C is housed in a 100-lead Thin Quad Flat Pack (TQFP) package, 14 mm × 14 mm, 0.5 mm lead pitch, RoHS-compliant, with exposed pad not electrically connected.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 26, 51, 76) | Ground reference | Four dedicated ground pins reduce ground bounce and improve signal integrity for high-speed CPLD logic transitions. |
| VCC (Pins 25, 50, 75, 100) | Power supply | Four 5 V supply pins ensure stable core and I/O voltage delivery under dynamic switching loads. |
| TCK, TMS, TDI, TDO | JTAG interface | Enable boundary-scan test access and in-system programming without requiring dedicated programming hardware. |
| TDI, TDO, TMS, TCK, TRST | JTAG test access port | Supports IEEE 1149.1 compliance for production test, field reprogramming, and design validation. |
| I/O[0]–I/O[83] | User-configurable bidirectional I/O | 84 pins support programmable input, output, or bidirectional operation with slew-rate control and pull-up options. |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability | Enables field firmware updates and logic revisions without device removal or socketing, reducing maintenance downtime. |
| Three function blocks | Provides modular logic partitioning-each block operates independently with local interconnect, easing timing closure and debugging. |
| Programmable slew-rate control | Reduces EMI and overshoot on high-speed I/O traces by limiting edge rates, critical for noise-sensitive industrial environments. |
| Global and local clock networks | Supports multiple synchronous domains within one device, allowing independent clocking of state machines or data paths. |
| Individual macrocell output enable | Permits fine-grained bus contention management and dynamic I/O direction control without external logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based logic replacement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3128XL-10VQ100C | 128 macrocells, 3.3 V core/I/O, 10 ns speed grade, Flash-based configuration. | Requires level-shifting in 5 V systems; better suited for new low-power designs with tighter timing budgets. | Select when migrating from 5 V to 3.3 V infrastructure and needing faster propagation delay. |
| XC9572-15PC84C | 72 macrocells, 84-pin PLCC package, 15 ns speed, same 5 V architecture and JTAG interface. | Lower logic density and smaller I/O count; suitable for simpler control tasks where footprint or cost is constrained. | Select when full 108-macrocell capacity is unnecessary and PLCC socket compatibility is required. |
Compared with XC95108-20TQ100C, the XCR3128XL-10VQ100C offers higher speed and lower voltage but demands system-level voltage redesign, while the XC9572-15PC84C retains full architectural compatibility at reduced scale and different packaging-making it a direct upgrade/downgrade path within the same legacy ecosystem.

FAQ
What is the operating voltage range for XC95108-20TQ100C?
The XC95108-20TQ100C operates at a nominal supply voltage of 5.0 V ± 10%, meaning it functions reliably between 4.5 V and 5.5 V. This matches legacy TTL and 5 V CMOS logic families, eliminating the need for voltage translation in retrofitted systems. The XC95108-20TQ100C does not support 3.3 V core operation.
Does XC95108-20TQ100C support in-system programming?
Yes, XC95108-20TQ100C supports in-system programming via its IEEE 1149.1-compliant JTAG interface. This allows full device configuration, erasure, and verification while soldered on the target PCB. The XC95108-20TQ100C requires only a standard JTAG cable and compatible software such as Xilinx ISE or third-party programmers.
How many user I/O pins does XC95108-20TQ100C provide?
The XC95108-20TQ100C provides 84 user-programmable I/O pins in its 100-pin TQFP package. These pins support configurable input, output, or bidirectional modes, with programmable slew-rate control and weak pull-up options. The remaining 16 pins are dedicated to power, ground, and JTAG signals.
Is XC95108-20TQ100C still in production or considered obsolete?
XC95108-20TQ100C is listed as obsolete by AMD/Xilinx, but Aetrix Electronics maintains active inventory and authorized distribution channels for continued supply. Lifecycle documentation confirms last-time-buy dates have passed, yet Aetrix supports extended availability through consignment stock and controlled allocation for qualified industrial customers relying on the XC95108-20TQ100C.
What software tools are required to program XC95108-20TQ100C?
XC95108-20TQ100C is supported by Xilinx ISE Design Suite (versions up to 14.7), including the Foundation and WebPACK editions. Programming requires the XC9500-specific compiler, JEDEC file generation, and JTAG download via compatible cables (e.g., Xilinx DLC10 or Digilent HS2). The XC95108-20TQ100C is not supported by Vivado.
