XC2C128-7TQ144C - 128-Macrocell 1.8V CPLD | AMD Xilinx
N.º da peça: XC2C128-7TQ144C ✓ AtivoXC2C128-7TQ144C Visão geral
A CPLD is a programmable semiconductor that combines multiple programmable logic blocks and a flexible interconnect in one package. The CPLD hierarchy is complex programmable logic device, programmable logic device, digital logic IC, and integrated circuit. Compared with an FPGA, a CPLD generally provides simpler configuration, deterministic startup behavior, and useful low-power operation for fixed control, interface, and glue-logic functions.
The XC2C128-7TQ144C combines 128 macrocells with 152 MHz system performance and 4.5 ns pin-to-pin timing. Its 1.8 V supply orientation supports modern low-voltage digital systems, while the 13 µA quiescent-current figure makes it relevant to portable and power-conscious equipment. The 80 user I/O pins provide substantial connectivity for bus arbitration, state machines, data capture, address decoding, and peripheral control.
The device uses 0.18 µm CMOS technology and belongs to the CoolRunner-II family, whose Fast Zero Power architecture targets low static power in portable systems. Nonvolatile configuration means the programmed logic is retained without continuous configuration-memory writes. Designs can implement deterministic control logic, parallel-to-serial data conversion, clock-domain interface functions, and fixed-format signal processing without using a larger FPGA.
Typical uses include industrial automation, portable instrumentation, embedded control, communications interfaces, and power-management sequencing. In an industrial controller, the CPLD can combine legacy bus interfaces with deterministic actuator logic. In portable equipment, its low quiescent current and 80 I/O pins can simplify control around a host processor. In communications equipment, the 4.5 ns pin-to-pin delay supports faster combinational paths than a slower speed grade.
Designers should use the AMD DS093 device specification for the exact 144-pin assignment, configuration interface, voltage limits, and timing constraints. PCB routing must preserve the recommended power and ground distribution, while unused inputs should be handled according to the device guidance. The 144-pin TQFP footprint also requires careful assembly planning because its 0.5 mm pitch limits routing and inspection access.
This page combines the key device characteristics, documented package details, practical application guidance, and qualified same-package alternatives. It also identifies unresolved electrical details that engineers should confirm in the manufacturer specification before releasing a production schematic or PCB footprint.

Aplicações típicas
XC2C128-7TQ144C é adequado para 6 aplicaçãos: Industrial Control and Automation, Portable Instrumentation, Communications Interface Control, Data Capture and Signal Conditioning, Power Management Sequencing, Embedded System Glue Logic.
Industrial Control and Automation
The XC2C128-7TQ144C fits deterministic machine-control logic because it provides 128 macrocells, 80 user I/O pins, and a 4.5 ns pin-to-pin propagation delay in a 144-pin TQFP. It can implement limit-switch decoding, actuator sequencing, interlock logic, and legacy peripheral interfaces beside a host processor. Nonvolatile configuration allows the controller to restart with deterministic logic state. The stated 0 °C to 70 °C operating range suits commercial-temperature equipment; extended-temperature industrial machinery should use the appropriate industrial-grade family variant.
Recomendado
Portable Instrumentation
The 1.8 V XC2C128-7TQ144C is useful in portable measurement equipment where low static power and deterministic startup are important. Its 13 µA quiescent-current figure and nonvolatile CoolRunner-II architecture help reduce activity beyond the active measurement interval. The 128 macrocells can consolidate acquisition control, trigger logic, status decoding, and display-interface functions. Designers must still budget normal active-path power and verify the complete system current, rather than treating the quiescent figure as total operating consumption.
Recomendado
Communications Interface Control
The XC2C128-7TQ144C can implement protocol framing, byte alignment, parity generation, and interface isolation in communications equipment. With 80 user I/O pins, it provides ample connections for parallel data buses, control signals, and status indicators, while the 4.5 ns propagation delay supports faster combinational decisions than slower speed grades. Nonvolatile configuration makes the interface behavior available immediately after power-up. Final timing closure should use the external interface clock and the device timing constraints documented in DS093.
Recomendado
Data Capture and Signal Conditioning
For acquisition and signal-conditioning systems, the XC2C128-7TQ144C can perform parallel sampling control, trigger qualification, programmable delays, and data-format conversion before transfer to a processor. Its 128 macrocells permit several independent logic functions without multiplying package count, and its 4.5 ns path delay helps minimize delay between capture command and control output. The 144-pin package supports 80 user I/O pins but requires careful escape routing on dense boards. Signal-integrity decisions remain governed by external buffers, trace topology, and the board environment.
Recomendado
Power Management Sequencing
The XC2C128-7TQ144C can supervise rail order, monitor power-good signals, generate programmable delays, and coordinate enables in a multi-rail embedded system. Its 80 user I/O pins allow multiple voltage domains and supervisory inputs to be handled by one deterministic controller, and nonvolatile configuration preserves sequencing rules after power cycling. The 1.8 V device should be powered from a suitable rail, while its inputs and outputs must remain within the electrical limits defined in DS093. Review power-up ordering and metastability controls in the system architecture.
Recomendado
Embedded System Glue Logic
The XC2C128-7TQ144C is well suited to fixed logic that connects processors, memories, and legacy peripherals. Typical tasks include address decoding, bus arbitration, interrupt routing, watchdog handling, and reconfigurable I/O adapters. Consolidating these functions in a 128-macrocell CPLD can reduce processor software overhead and avoid using a larger FPGA. The 0.18 µm CMOS CoolRunner-II implementation combines deterministic configuration with low static power, while the TQFP-144 package offers a conventional surface-mount assembly option. Validate fanout and voltage compatibility for every connected device.

Notas de projeto
Use the land pattern and pin numbering in AMD document DS093 rather than a generic 144-pin TQFP footprint. The device uses a 0.50 mm pitch, so route configuration, clock, data, and ground pins with short escapes where possible. Preserve uninterrupted ground references beneath the device, place bypass capacitance at the specified power pins, and verify board dimensions against the package drawing before releasing fabrication output.
Assign clocks and high-fanout signals to pins according to the device's timing and clock constraints in DS093. The 4.5 ns pin-to-pin figure describes the device speed grade but does not include PCB propagation or round-trip clock delay. Use controlled-impedance routing for external interfaces, minimize stubbing, and apply series termination where the connected source or receiver requires it to control edge reflections.
Follow the manufacturer's recommended supply topology, decoupling positions, and voltage tolerances in DS093. Keep the 1.8 V rail free of excessive ripple and place each required bypass capacitor close to its associated power pin. Since the published 13 µA figure is a quiescent-current value, calculate total regulation loss separately from static device consumption and provide the CPLD with adequate current headroom during configuration.
Do not substitute a 100-pin XC2C128 package variant for this 144-pin device, and do not treat a slower speed grade as an automatic equivalent. XC2C128-6TQ144C changes propagation delay from 4.5 ns to 5.7 ns, which can break a path near the timing limit. After any substitution, confirm package dimensions, pin names, configuration compatibility, voltage ratings, and every external timing constraint.
Informações de conformidade
No definitive RoHS, REACH, lead-free, halogen-free, or conflict-minerals declaration was identified. AEC-Q100 is marked not applicable because this is a programmable logic device rather than an automotive-grade semiconductor declaration.
