Product details
Overview
XC95108-15PC84I from AMD is a high-density, in-system programmable CPLD featuring 108 macrocells, 5 ns pin-to-pin propagation delay, and operation up to 64.5 MHz. It implements complex combinational and sequential logic in industrial control, communication interface logic, and legacy system glue logic.
For engineers reviewing the XC95108-15PC84I datasheet, pinout, applications, or equivalent options, key selection factors include I/O count (84 pins), 5 V tolerant inputs, JTAG boundary-scan test support, and in-system programmability via IEEE 1149.1 interface.
Technical Context
The XC95108-15PC84I belongs to the XC9500 family of CPLDs built on 0.5 µm CMOS technology. It contains four function blocks, each with 27 macrocells, and supports global and product-term clocking with up to 90 product terms per macrocell.
It uses a programmable interconnect matrix for flexible routing between function blocks and I/O pins. Configuration is stored in non-volatile EEPROM, enabling single-chip operation without external configuration memory.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocells | 108 macrocells distributed across 4 function blocks; enables implementation of medium-complexity logic functions without FPGA-level overhead. |
| Propagation Delay | 5 ns maximum pin-to-pin delay; supports synchronous logic operation at up to 64.5 MHz system clock frequency. |
| I/O Pins | 84 user I/O pins with 5 V-tolerant inputs; allows direct interfacing with legacy TTL/CMOS systems without level-shifting. |
| Supply Voltage | 5.0 V ± 10%; compatible with standard 5 V digital power rails and eliminates need for dedicated low-voltage regulators. |
| Programmability | In-system programmable via JTAG (IEEE 1149.1); enables field firmware updates and design iteration without device removal. |
| Configuration Memory | Non-volatile EEPROM; retains logic configuration after power cycle, eliminating boot-time configuration delays. |
Pinout & Package
XC95108-15PC84I is housed in an 84-pin plastic leaded chip carrier (PLCC) package with J-lead configuration, suitable for socketed or surface-mount assembly in industrial environments requiring mechanical robustness and thermal cycling resilience.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Provides common return path for all internal logic and I/O circuits; requires low-impedance PCB connection to minimize noise coupling. |
| VCC | Power supply | Supplies 5 V to core logic and I/O buffers; decoupling capacitors must be placed near each VCC pin per layout guidelines. |
| TCK, TMS, TDI, TDO | JTAG boundary-scan interface | Enables IEEE 1149.1-compliant programming, verification, and test without dedicated programming hardware. |
| I/O/GCLK1–GCLK4 | Global clock inputs | Four dedicated low-skew clock inputs drive all function blocks; critical for synchronous state machine timing integrity. |
| I/O pins (1–84) | Configurable bidirectional I/O | Each pin supports input, output, or bidirectional mode with configurable slew rate and pull-up; mapped directly to macrocell outputs or inputs. |
Key Features
| Feature | Design Value |
|---|---|
| 5 ns pin-to-pin delay | Ensures deterministic timing closure in high-speed control logic with minimal added latency. |
| 108 macrocells with 90 PTs/macrocell | Supports large combinatorial equations or deep state machines within a single device, reducing inter-device routing complexity. |
| JTAG in-system programming | Eliminates need for UV erasers or external programmers; enables reconfiguration during system operation or field service. |
| 5 V-tolerant I/O | Permits seamless integration into mixed-voltage systems where legacy 5 V peripherals coexist with newer 3.3 V controllers. |
| EEPROM-based configuration | Removes dependency on external configuration PROMs or microcontroller bootloaders, simplifying BOM and startup sequence. |

FAQ
What is the maximum operating frequency supported by the XC95108-15PC84I?
The XC95108-15PC84I supports a maximum system clock frequency of 64.5 MHz, derived from its 5 ns pin-to-pin propagation delay specification. This value is measured under worst-case conditions (VCC = 4.5 V, TA = 70°C) and applies to synchronous logic paths routed through the device's macrocell array and interconnect matrix. The XC95108-15PC84I achieves this performance using dedicated global clock inputs and low-skew routing resources.
Does the XC95108-15PC84I require an external configuration memory?
No, the XC95108-15PC84I does not require external configuration memory. Its logic configuration is stored in on-chip non-volatile EEPROM, which retains data after power removal. Upon power-up, the XC95108-15PC84I automatically initializes its logic array without boot-time delays or host processor involvement, enabling true single-chip operation.
Is the XC95108-15PC84I compatible with 3.3 V logic interfaces?
The XC95108-15PC84I features 5 V-tolerant I/O pins but operates exclusively from a 5.0 V ±10% supply. While inputs accept 3.3 V logic levels safely, outputs swing to 5 V levels and are not 3.3 V compatible without external level-shifting circuitry. For mixed-voltage systems, the XC95108-15PC84I serves best as the 5 V domain controller interfacing to 3.3 V peripherals via resistive or active translators.
Can the XC95108-15PC84I be reprogrammed in the target system?
Yes, the XC95108-15PC84I supports in-system programming (ISP) via its IEEE 1149.1 JTAG interface (TCK, TMS, TDI, TDO). Reprogramming can be performed without removing the device from the PCB, using standard JTAG adapters and AMD-provided software tools. This capability enables field firmware updates, design iterations, and post-deployment logic corrections for the XC95108-15PC84I.
What package type is used for the XC95108-15PC84I?
The XC95108-15PC84I is packaged in an 84-pin plastic leaded chip carrier (PLCC) with J-shaped leads. This package supports both socketed insertion for prototyping and repair, and surface-mount reflow assembly. Its thermal and mechanical characteristics meet industrial requirements for extended temperature operation (–40°C to +85°C) and repeated thermal cycling.
