XC2C128-6VQ100C - 128-Macrocell 6ns CPLD | AMD
MPN: XC2C128-6VQ100C ✓ ActiveXC2C128-6VQ100C Overview
A complex programmable logic device, or CPLD, is a user-programmable semiconductor that combines multiple programmable logic blocks with a deterministic internal interconnect. The CoolRunner-II architecture places the XC2C128 in the broader hierarchy of programmable logic devices: CPLD, programmable logic, semiconductor, and digital logic IC. Its macrocell-based structure is particularly useful when a design needs predictable signal routing, compact logic integration, and relatively straightforward reconfiguration during product development.
The XC2C128 family provides 128 macrocells, 80 inputs, and clock performance up to 152 MHz. The -6 suffix identifies the 6 ns propagation-delay performance grade, while the VQ100 suffix identifies the 100-terminal package. The C suffix identifies the commercial temperature grade. These characteristics make the part useful for bus decoding, state machines, traffic-light controllers, industrial sequencing, data-capture logic, and general-purpose embedded control.
Unlike an FPGA with a large array of general-purpose logic and routing resources, a 128-macrocell CPLD is suited to compact deterministic designs where a modest number of gates, registers, and interconnect paths are required. Its architecture can simplify timing closure for modest control logic and reduce the need for external glue devices. Designers should still evaluate every clock domain, asynchronous input, output timing constraint, and pin assignment against the device timing report.
Typical uses include industrial automation, telecommunications, consumer control, embedded systems, instrumentation, and communication-interface logic. The 152 MHz maximum clock rating supports designs in which the CPLD performs protocol conversion, data formatting, or bus arbitration, while the 6 ns grade can be valuable for short combinational or registered paths. The 100-terminal package also offers more I/O than a small logic PLD, allowing multiple external interfaces to share one programmable device.
For a reliable implementation, use the AMD DS093 pinout and package information when assigning the PCB footprint, connect unused inputs to defined levels, and validate timing after programming. Place decoupling close to the supply pins, route clocks as controlled signals, and confirm that every external interface has compatible voltage levels. Configuration and power-up sequencing must follow the CoolRunner-II design guidance.
This product page consolidates the device specifications, package details, sourcing guidance, pin-compatible family alternatives, comparison parameters, and practical implementation notes into one engineering reference. The alternatives and comparisons help identify speed- and temperature-grade options, while the design notes focus on PCB, timing, configuration, and signal-integrity decisions that are essential beyond the headline CPLD specifications.

Typical Applications
XC2C128-6VQ100C is suitable for 6 applications: Industrial Control and Sequencing, Telecommunications Data Formatting, Embedded System Bus Arbitration, Instrumentation Signal Conditioning, Interface Protocol Conversion, LED Display and Illumination Control.
Industrial Control and Sequencing
The XC2C128-6VQ100C fits compact industrial sequencing logic because its 128 macrocells can combine state machines, interlocks, input conditioning, and output-control functions in one programmable device. The 6 ns propagation-delay grade provides useful timing margin for short combinational paths, while the 80-input count supports multiple discrete sensors and machine-status signals. Engineers can implement the control law in the CPLD instead of spreading it across several fixed logic ICs. Timing, electrical, and environmental qualification against the AMD DS093 specification remains essential before deployment in machinery.
Recommended
Telecommunications Data Formatting
The XC2C128-6VQ100C is appropriate for telecommunications line-card logic that requires deterministic parallel-to-serial conversion, framing, byte alignment, or status decoding. Its 128 macrocells permit multiple pipeline stages and control registers, while the stated clock capability of up to 152 MHz supports moderately fast internal processing. The 100-terminal package provides additional I/O for parallel buses and control signals. For production designs, constrain all synchronous paths, register asynchronous inputs, and verify line-rate requirements against the 6 ns device timing grade.
Recommended
Embedded System Bus Arbitration
The XC2C128-6VQ100C can implement deterministic arbitration, address decoding, bus timing, and interrupt routing between a microcontroller and one or more peripherals. Its 128 macrocells are sufficient for multiple finite-state machines and registered handshake logic, and the 6 ns grade supports short acquisition paths around the 152 MHz clock limit. A dedicated CPLD can also isolate timing-critical handshakes from the host processor. Engineers should define bus ownership in the design tools and confirm that every asynchronous request passes through synchronized logic before use.
Recommended
Instrumentation Signal Conditioning
For instrumentation and test systems, the XC2C128-6VQ100C can implement digital filtering, trigger logic, counter pipelines, and interface sequencing around analog front ends. The 128-macrocell capacity allows measurement algorithms and control registers to coexist, while the 100-terminal package supports multiple data and control connections. The 6 ns grade is useful when trigger paths must be sampled on closely spaced clock edges. Timing closure must include the delays of connected amplifiers and converters, and each input crossing between clock domains needs an appropriate synchronization scheme.
Recommended
Interface Protocol Conversion
The XC2C128-6VQ100C is well suited to protocol conversion between legacy parallel interfaces and newer serial or mixed-signal systems. Engineers can place format converters, FIFO-like queues, command decoders, and interrupt logic in the 128 available macrocells. Its up-to-152 MHz clock operation supports common control-clock rates, while the 80 inputs provide enough parallel signals for command multiplexing. Validate throughput, back-pressure behavior, and setup/hold timing at both device boundaries. Use registered outputs when downstream timing margins are tight.
Recommended
LED Display and Illumination Control
The XC2C128-6VQ100C can drive display multiplexing, pixel refresh sequencing, brightness-control decoding, and fault detection in LED-based systems. Its 128 macrocells support multiple refresh counters and character logic, while the 100-terminal package offers sufficient connections for display data and control signals. The 6 ns timing grade helps maintain deterministic scan timing, although LED drive limits and external driver delays must be included in the timing analysis. Choose external transistor or constant-current drivers whenever the required current exceeds the device’s directly supported output capability.

Key Differentiators
- Faster timing option than the 7 ns family alternatives (vs XC2C128-7VQ100C)
- Commercial-grade option within the same VQ100 footprint (vs XC2C128-6VQ100I)
- More timing margin than the slower speed grade (vs XC2C128-7VQ100I)
Design Notes
Use the VQ100 land pattern and pin numbering defined in AMD document DS093 rather than drawing the footprint from the 100-terminal count alone. Place the device where power and ground connections can follow the manufacturer’s recommended layout, connect all supply pins, and route test or programming access as needed for production programming. Verify courtyard clearance, lead pitch, solder-mask polarity, and pin-1 orientation against the package drawing before fabrication.
Clock, configuration, and high-speed I/O nets should have short, continuous return paths and avoid crossing noisy switching regions. Apply clock-period, setup, hold, and I/O timing constraints in the design tools, then review both worst-case timing reports and board-level signal integrity. The stated 152 MHz maximum clock is a device capability rather than a guarantee that every external interface will operate at that rate.
Do not treat a faster or slower XC2C128 speed grade as automatically interchangeable. The -6 part provides a 6 ns propagation-delay designation, while a -7 alternative provides 7 ns; a design constrained to the original timing target must be revalidated. Also distinguish the VQ100 package from VG100 or other package codes, and distinguish commercial C suffixes from industrial I suffixes before approving a substitution.
Follow the decoupling network and power-supply recommendations in DS093, placing bypass capacitors close to the relevant supply pins and minimizing loop area. Check supply voltage limits, startup current, configuration behavior, and the power consumed by the selected logic implementation. External loads such as displays, transceivers, and pull networks must be included in the board-level power budget.
