XC2C128-7VQ100I - 128-Macrocell 4.5ns CPLD | Xilinx
N.º de pieza: XC2C128-7VQ100I ✓ ActivoXC2C128-7VQ100I Descripción general
A complex programmable logic device, or CPLD, is a programmable semiconductor that combines multiple logic functions into one reconfigurable integrated circuit. Its position in the hardware hierarchy is programmable logic, followed by field-programmable gate arrays and larger application-specific programmable devices. CoolRunner-II devices use nonvolatile configuration memory, allowing the programmed logic to remain available after power is removed without an external configuration PROM.
The XC2C128 provides up to 128 macrocells and 80 user I/O pins in a compact 14 x 14 mm surface-mount package. Its 4.5 ns pin-to-pin propagation delay makes it suitable for control logic, bus arbitration, address decoding, interface translation, and industrial automation functions that require deterministic combinational or registered operation. Quiescent current can be as low as 13 uA, which benefits low-power portable and embedded equipment.
The device uses CMOS technology and is designed around a 1.8 V supply. A comparison page identifies a 1.7 V to 1.9 V operating range for the related VQ100 package option, while the product description specifically identifies the XC2C128-7VQ100I as optimized for 1.8 V systems. The -7 speed designation identifies the performance grade, and the VQ100 designation identifies the 100-pin VQFP package used by this ordering code.
Typical implementations include industrial control and automation, portable instrumentation, communication-interface glue logic, power-management sequencing, and compact embedded systems. The nonvolatile architecture and low quiescent current are particularly useful when the system must resume its programmed logic immediately after power restoration or operate from a constrained battery supply.
PCB design should preserve the manufacturer's recommended supply decoupling, provide a clean ground reference, and route high-current or high-speed edges away from sensitive control inputs. Because this is a 100-pin programmable device, programming-file compatibility, pin constraints, and unused I/O handling must be verified in the CoolRunner-II design flow before release to manufacturing.
This product record combines device specifications, package and pin-count information, current sourcing references, drop-in replacement analysis, and practical CPLD design guidance. It is intended to help engineers compare the XC2C128-7VQ100I with same-package CoolRunner-II options while keeping PCB, timing, and environmental requirements visible during component selection.

Aplicaciones típicas
XC2C128-7VQ100I es adecuado para 6 aplicacións: Industrial Control and Automation, Embedded Interface Consolidation, Low-Power Portable Instrumentation, Communication Interface Termination, Power-Sequencing and Management Logic, Data Acquisition and Signal Conditioning.
Industrial Control and Automation
The XC2C128-7VQ100I fits centralized industrial control logic because its 128 macrocells can consolidate sequencing, state-machine, and bus-arbitration functions while the -7 grade provides a 4.5 ns maximum pin-to-pin propagation delay. Its 80 user I/O pins support connections to sensors, actuators, and field buses within a compact 14 x 14 mm VQFP footprint. The listed 0 C to 70 C operating range suits ordinary industrial enclosure conditions, but extended-temperature requirements need a different qualified ordering code.
Recomendado
Embedded Interface Consolidation
The XC2C128-7VQ100I can bridge dissimilar embedded interfaces by translating signals, decoding addresses, and implementing protocol state machines in one configurable device. Its 80 user I/O pins reduce the need for separate glue logic, while the 4.5 ns -7-grade propagation delay is useful for short combinational paths and registered control sequences. Nonvolatile configuration also allows the interface behavior to be restored immediately after power cycling without relying on a separate configuration memory.
Recomendado
Low-Power Portable Instrumentation
The XC2C128-7VQ100I is appropriate for portable instruments that require deterministic programmable logic without the power cost of a large FPGA. Its quoted minimum quiescent current of 13 uA benefits battery-powered operation, and nonvolatile configuration preserves the programmed instrument behavior when power is removed. The 128-macrocell resource can handle control, measurement sequencing, and interface conversion, while the 4.5 ns -7-grade delay supports responsive signal routing.
Recomendado
Communication Interface Termination
The XC2C128-7VQ100I can implement protocol conversion, framing, and endpoint logic in communication equipment where moderate logic density is needed. Its 80 user I/O pins provide substantial parallel connectivity, and the -7 grade's 4.5 ns propagation-delay class can support fast control paths and registered data-transfer logic. Nonvolatile configuration allows the interface personality to remain present after power restoration, which is useful in equipment with infrequent service access.
Recomendado
Power-Sequencing and Management Logic
The XC2C128-7VQ100I can implement deterministic power-up sequencing, rail monitoring, fault latching, and control interlocks where a hardwired state machine is cumbersome. Its 128 macrocells allow multiple sequencing paths and supervisory functions to coexist, while the 80 I/O pins provide ample connections to regulators, enables, and status signals. The 4.5 ns propagation-delay specification supports rapid control response, and nonvolatile configuration preserves programmed sequencing behavior during power interruptions.
Recomendado
Data Acquisition and Signal Conditioning
The XC2C128-7VQ100I is useful as acquisition front-end support logic for multiplexing, sample sequencing, trigger coordination, and data-format conversion. Its 80 user I/O pins can connect multiple converters and digital sensors, while the 4.5 ns -7-grade delay class handles short control and capture paths. The CPLD can also implement digital correction around converters without burdening the host processor, and nonvolatile configuration preserves the acquisition sequence across power cycles.

Notas de diseño
Place the required supply-decoupling capacitors directly at the XC2C128-7VQ100I power and ground pins, following the manufacturer datasheet's recommended values and layout. The device is optimized for 1.8 V systems, so verify every connected I/O's voltage domain before enabling the pins. Keep the 13 uA quiescent-current figure in mind for battery designs, but calculate the complete energy budget from actual core activity and I/O switching rather than treating the minimum as a continuous active-current value.
Route the 100-pin VQFP footprint with a 0.50 mm pitch and inspect the manufacturer package drawing for pin 1 orientation. Provide short, direct return paths for supply and ground connections, avoid placing switching nodes beneath the device, and maintain the recommended clearance around configuration and dedicated pins. Check the complete pin-description table in the datasheet because only the 80 user I/O count is available from the retrieved product listing.
Do not approve a replacement or board spin solely from the family name. The XC2C128-7VQG100I is the identified same-package alternative, but its suffix, package marking, temperature treatment, and programming-device settings should still be reconciled against the original design. Generate the configuration file for the exact selected ordering code and review all unused pins, configuration pins, and I/O constraints in the CoolRunner-II design tool.
Información de cumplimiento
No explicit RoHS, REACH, lead-free, halogen-free, or conflict-minerals statements were found. AEC-Q100 is not applicable because this is a programmable logic device rather than an automotive-qualified component.
