XC2C128-7TQ144I - 128-Macrocell 7ns Industrial CPLD | AMD
Référence : XC2C128-7TQ144I ✗ Fin de vieXC2C128-7TQ144I Présentation
A CPLD is a programmable-logic semiconductor that combines interconnected macrocells, programmable interconnect resources, and configuration memory in one package. The XC2C128 belongs to the CoolRunner-II family hierarchy of complex programmable logic devices, where it sits between smaller CPLD densities and larger FPGA implementations. Its purpose is to implement control, interface, decoding, state-machine, and fixed datapath functions without requiring a mask change or external configuration device.
The device provides 128 macrocells, eight function blocks, 3,000 usable system gates, and 100 user I/O pins in its 144-lead TQFP package. The -7 suffix denotes the 7 ns speed grade, while the I suffix identifies the industrial temperature option. Its 0.18 µm CMOS construction and Fast Zero Power technology support low-power operation for portable equipment, telecommunications, and embedded systems where deterministic startup and compact non-volatile logic are important.
CoolRunner-II architecture organizes the 128 macrocells into eight function blocks. Each block contains programmable logic and interconnect resources, allowing multiple control paths to be implemented with consistent timing. The architecture is appropriate for bus interface logic, protocol conversion, address decoding, state machines, and glue logic that must retain its configuration when power is removed. Because the configuration is non-volatile, no separate configuration ROM is required for normal operation.
Typical uses include telecommunications line-interface control, portable and embedded equipment, industrial automation, data-acquisition systems, and general-purpose interface bridging. The 100 user I/O pins provide substantial connectivity for parallel buses and multi-bit control logic, while the 144-pin TQFP footprint supports conventional surface-mount assembly. Industrial temperature grading makes the device suitable for equipment expected to operate across extended environmental conditions.
PCB design should preserve the TQFP-144 footprint and route every dedicated power and ground pin directly to their corresponding planes. Decoupling should follow the AMD CoolRunner-II guidance, with high-frequency bypass capacitance placed close to the package. Timing paths should be reviewed against the selected -7 speed grade, and unused I/O pins should be configured according to the device guidelines rather than left mechanically unconstrained.
This page combines the manufacturer specification with practical guidance for pin-compatible alternatives, application selection, timing-oriented design, and procurement. It also distinguishes verified technical attributes from parameters that still require engineering confirmation, helping designers make a safer CPLD sourcing and replacement decision.

Applications typiques
XC2C128-7TQ144I convient pour 6 applications: Telecommunications Line-Interface Control, Embedded Control and State Machines, Parallel Bus Interface Bridging, Industrial Automation Logic, Portable and Battery-Powered Equipment, Data Acquisition and Instrumentation.
Telecommunications Line-Interface Control
The XC2C128-7TQ144I fits telecommunications line-card control because it combines 128 macrocells with 100 user I/O pins in a 144-pin TQFP package. Its 7 ns speed grade supports deterministic parallel control paths, while the industrial-temperature option suits extended-range equipment. Engineers can implement line multiplexing, supervisory state machines, command decoding, and backplane arbitration without an external configuration memory. The practical benefit is compact, non-volatile logic with ample I/O for legacy telecom interfaces. Timing paths should still be checked against the 7 ns grade under worst-case supply and temperature conditions.
Recommandé
Embedded Control and State Machines
The XC2C128-7TQ144I is appropriate for embedded state-machine and sequencing logic where non-volatile configuration and predictable I/O behavior are essential. Its eight function blocks and 128 macrocells provide enough capacity for parallel control engines, priority logic, and handshake circuits, while the 100 user I/O pins reduce the need for external glue devices. Because configuration is retained in the device, the logic can restart without a separate configuration PROM. Designers should partition critical timing across function blocks according to the AMD architecture and verify worst-case delay constraints in the selected 7 ns speed grade.
Recommandé
Parallel Bus Interface Bridging
The XC2C128-7TQ144I can bridge parallel buses when both sides require many individually controlled signals and deterministic non-volatile logic. Its 100 user I/O pins can accommodate substantial data, address, and handshake connectivity, while the 128-macrocell architecture supports conversion tables, protocol checking, and FIFO-like control logic. The 7 ns grade provides a defined basis for timing analysis on shorter routes. PCB implementation should group related signals, provide continuous ground planes, and separate clock-sensitive routing from switching nodes to reduce timing uncertainty and crosstalk.
Recommandé
Industrial Automation Logic
The XC2C128-7TQ144I supports industrial automation functions such as sequencer control, machine-state decoding, interlock logic, and peripheral bus arbitration. The 128 macrocells and eight function blocks provide moderate logic density without moving to an FPGA, and the 144-pin TQFP package offers a conventional surface-mount assembly format. Its industrial-temperature designation is the principal reason to prefer it over a commercial-grade alternative in extended-range equipment. Designers should account for signal conditioning, isolation, surge protection, and grounding at the board interface rather than expecting the CPLD to replace external protection hardware.
Recommandé
Portable and Battery-Powered Equipment
The XC2C128-7TQ144I can serve portable equipment that benefits from non-volatile programmable logic and CoolRunner-II Fast Zero Power technology. The device retains its configuration after power removal and offers 128 macrocells for consolidating discrete control functions into one package. A compact 144-pin TQFP also supports space-conscious assemblies, although board density should be balanced against thermal and routing requirements. Power-budget calculations should include the selected device's actual operating and standby current under the intended clocking conditions rather than relying on the family name alone.
Recommandé
Data Acquisition and Instrumentation
The XC2C128-7TQ144I is suitable for data-acquisition front ends that require trigger sequencing, channel control, status decoding, and interface isolation between measurement logic and a host processor. Its 100 user I/O pins allow parallel capture-control signals, and the non-volatile configuration supports repeatable instrument startup. The 7 ns speed grade is useful for short control loops, although analog settling, ADC conversion time, and board-level propagation dominate overall latency. Engineers should partition trigger and data paths carefully and apply the manufacturer timing constraints to each implemented function.

Notes de conception
Use the exact 144-pin TQFP land pattern and pin-1 orientation defined by AMD DS093. Route every dedicated power pin directly to the appropriate supply plane and every ground pin directly to the ground plane; avoid adding plane transitions beneath the device. Place the required bypass capacitors close to their corresponding pins and minimize loop area. A TQFP-144 footprint offers fine-pitch routing, so inspect the assembly drawing for pin-1, thermal, and lead-identification conventions before fabrication.
Separate clocks, configuration signals, and timing-sensitive control paths from noisy switching nodes wherever the TQFP-144 pin assignment permits. Provide a continuous reference plane, use short point-to-point clock routing, and avoid stubs or unnecessary test pads on sensitive nets. Although the device is a CPLD, external signal arrival skew and board propagation can still determine interface timing, so validate complete paths rather than relying only on the nominal 7 ns internal speed grade.
Do not treat a package-compatible XC2C128 grade as automatically interchangeable. The target is the industrial 7 ns version, while several alternatives change speed or temperature class. Before substitution, compare the ordering code, operating-temperature limits, supply limits, timing constraints, and configuration behavior in DS093. Also confirm that the selected alternative is in the 144-pin TQFP format rather than the 100-pin VQFP format, which requires a different board footprint.
Thermal analysis must reflect the actual XC2C128-7TQ144I utilization, ambient temperature, and switching activity. A dense design can consume more power than a lightly loaded CPLD, while the TQFP-144 package relies on board copper for heat removal. Place the device away from heat-generating components where practical and provide uninterrupted copper around the package. Use the power and thermal data in DS093 for a worst-case calculation rather than estimating from the process node.
