XC2C256-7TQG144C 概述
A complex programmable logic device, or CPLD, is a programmable-logic semiconductor that combines interconnected macrocells with programmable interconnect. In the broader hierarchy, a CPLD is a programmable logic device and an FPGA alternative. Unlike mask-programmed logic, a CPLD permits design changes without fabricating a new integrated circuit. The CoolRunner-II architecture also uses nonvolatile configuration storage, allowing the programmed logic to remain available after power is removed.
The XC2C256 family provides 16 logic array blocks and 256 macrocells according to the available product data. Its -7 speed designation corresponds to the reported 6.7 ns propagation-delay class. With 118 user I/O pins, it supports parallel external interfaces and board-level control functions. The 1.7 V to 1.9 V internal supply range is suitable for systems designed around the device's documented core operating conditions.
Typical uses include industrial control, communications equipment, portable electronics, programmable interface logic, bus arbitration, and compact control-plane functions. The CPLD can consolidate multiple fixed-function gates into one programmable device, reducing board area compared with a larger gate-array implementation when the required logic is modest. Designers should still verify timing, power, I/O standards, and pin constraints against the complete CoolRunner-II datasheet and their specific design.
The principal design consideration is tool and configuration compatibility. Existing CoolRunner-II projects depend on supported AMD or Xilinx programming tools, device support, and verified bitstream compatibility. Before replacing an installed device, engineers must check the exact package, speed grade, temperature grade, power behavior, and pin assignment rather than relying only on the family name.
This page consolidates the supplied distributor and manufacturer information, distinguishes verified facts from unavailable specifications, and adds selection and sourcing guidance. Because the provided data does not include a complete pin table, electrical limit table, or qualified replacement list, those fields remain explicitly marked for engineering review.

典型应用
XC2C256-7TQG144C 适用于 8 应用s: Industrial Control Logic, Communication Interface Consolidation, Portable Electronics, Programmable Bus Arbitration, Data Acquisition and Signal Routing, Motor and Power-System Control, Test and Measurement Front Ends, Educational and Prototype Logic.
Industrial Control Logic
The XC2C256-7TQG144C fits industrial control designs that require deterministic programmable logic without the resource level of a large FPGA. Its verified 256 macrocells and 118 I/O pins provide capacity for sequencing, interlocks, alarm handling, signal conditioning, and peripheral-control functions. The reported 6.7 ns propagation-delay class can support short control paths, while the 144-pin TQFP package provides a large external connection count. Engineers should verify the required I/O standards and operating-temperature range against the complete AMD DS094 datasheet before production release.
推荐
Communication Interface Consolidation
The XC2C256-7TQG144C can consolidate communication-adjacent control logic such as frame formatting, channel arbitration, status decoding, and peripheral interfacing. Its 118 user I/O pins offer substantial board connectivity, while 256 macrocells allow several modest state machines and Boolean functions to be placed in one programmable device. The reported 152 MHz maximum frequency is a useful design target, but actual interface timing depends on the selected architecture and external components. Use the manufacturer's timing data and pin constraints for final sign-off.
推荐
Portable Electronics
The XC2C256-7TQG144C is applicable to portable and embedded products when a nonvolatile, programmable control block is useful and the design fits its 256-macrocell capacity. It can implement power sequencing, display or keypad control, peripheral arbitration, and compact interface logic in a 144-pin surface-mount TQFP. The verified internal supply range of 1.7 V to 1.9 V must be integrated with the system power architecture, and the complete power-consumption data should be checked for battery-operated designs. The supplied source does not confirm a portable-specific qualification.
推荐
Programmable Bus Arbitration
The XC2C256-7TQG144C is well suited to programmable bus arbitration, address decode, and peripheral-select logic because these functions benefit from nonvolatile configuration and deterministic combinational or sequential behavior. The 118 I/O pins provide flexibility for connecting multiple buses and control signals, while 256 macrocells allow the design to include arbitration state, timeout handling, and status logic. The reported 6.7 ns propagation delay should be checked against the maximum bus timing budget, especially when fanout or external loading increases delay.
推荐
Data Acquisition and Signal Routing
The XC2C256-7TQG144C can serve programmable signal-routing, sampling-control, and data-acquisition support logic. Its 118 I/O pins allow multiple sensor, converter, and memory-control signals to be coordinated, while the programmable architecture allows the same board to support different routing tables or control sequences. The reported 6.7 ns propagation-delay class can assist with short control paths, but high-speed analog or ADC timing still depends on the external converter and board-level signal integrity. Confirm package pin availability and I/O voltage limits in the complete datasheet.
推荐
Motor and Power-System Control
The XC2C256-7TQG144C can implement control sequencing, protection interlocks, fault logging, and timing functions around a motor controller or power-conversion subsystem. Its 256 macrocells and 118 I/O pins allow the CPLD to coordinate multiple digital control signals while retaining a compact programmable footprint in TQFP144. The device should not be assumed to provide analog current sensing or direct power-stage drive. Its logic outputs must be interfaced through suitable drivers, and the final design must verify timing, grounding, isolation, and any safety requirements.
推荐
Test and Measurement Front Ends
The XC2C256-7TQG144C can be used for programmable test-point sequencing, instrument control, timing coordination, and peripheral multiplexing. The device's 118 I/O pins and programmable architecture allow a compact instrument front end to consolidate fixed control logic while retaining flexibility for different test configurations. The 6.7 ns propagation-delay class is useful for short control paths, but measurement accuracy and trigger jitter depend on the external analog and digital architecture. Verify supply integrity, I/O levels, and timing margins in the final instrument design.
推荐
Educational and Prototype Logic
The XC2C256-7TQG144C is useful for prototypes and educational logic platforms because it combines programmable nonvolatile configuration, substantial I/O availability, and a recognizable 144-pin TQFP footprint. Students or engineers can implement counters, decoders, state machines, bus interfaces, and small processor-control blocks without changing the PCB. The 256-macrocell capacity is larger than a basic demonstration CPLD, while the 6.7 ns timing class allows more realistic control experiments. Use the official programming tools and package pinout for reliable board bring-up.

设计说明
Do not substitute XC2C256-6TQG144C for XC2C256-7TQG144C solely because both use a TQFP144 designation. The -6 and -7 speed grades indicate different timing classes, and the supplied data does not prove identical pin behavior, electrical limits, or tool support. Perform a complete timing comparison and confirm the programming-tool device definition before releasing a substitution.
Use the official TQFP144 package drawing and complete AMD pin table before assigning PCB nets. The supplied data confirms a 144-pin TQFP package and 118 user I/O pins, but it does not include pin names or exposed-pad details. Preserve the package pin-1 orientation, verify power and ground distribution, and route high-transition signals away from sensitive analog or reference nets.
The verified internal supply range is 1.7 V to 1.9 V, so the power architecture must provide the required rail within that range while accounting for tolerance, startup sequencing, and local decoupling. The supplied data does not include recommended capacitor values or complete absolute-maximum ratings. Use the manufacturer datasheet for capacitor selection and do not infer I/O voltage compatibility from the internal core range.
Treat the reported 6.7 ns propagation delay and 152 MHz frequency as device-class data points, not guaranteed board timing. External load, package parasitics, I/O mode, clock skew, and the selected logic path determine the actual timing margin. Use the manufacturer's timing models or simulation tools and add measurement points for high-speed control, clock, or externally loaded nets.
合规信息
The supplied data does not state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is marked not_applicable only because the supplied data does not identify an automotive qualification claim; this is not an automotive qualification assertion.
