XC2C256-6TQ144C - 256-Macrocell 5.7 ns CPLD | AMD
Référence : XC2C256-6TQ144C ✗ Fin de vieXC2C256-6TQ144C Présentation
A CPLD is a programmable logic device that combines macrocell-based logic architecture with nonvolatile configuration memory. Within the programmable-logic hierarchy, the XC2C256 belongs to the complex programmable logic device family and uses its 256 macrocells to implement combinational and sequential control logic. This makes it useful for consolidating multiple programmable-logic functions into one device while retaining a straightforward, deterministic package footprint.
The CoolRunner-II architecture is optimized for effective logic synthesis and low static power requirements. Key features include as-fast-as 5.7 ns pin-to-pin delay, quiescent current as low as 13 µA, and operation optimized for 1.8 V systems. The -6 suffix identifies the speed grade, while TQ144 identifies the 144-pin thin quad flat package. The part contains 118 I/O, giving it substantially more external connectivity than smaller CPLDs in the same general technology family.
The XC2C256 architecture integrates 256 macrocells with programmable interconnect and configuration memory. Its 0.18 µm CMOS implementation supports deterministic signal routing and fixed package assignment, which are useful properties for control logic, bus arbitration, protocol bridging, and state-machine designs. Because configuration is nonvolatile, the logic operates immediately after power-up without requiring an external configuration loader.
Typical uses include industrial control systems, consumer equipment, telecommunications products, bus-interface logic, data-acquisition systems, and general-purpose glue logic. A design requiring more I/O than the 118 available user pins would need multiplexing or a different device family, while designs constrained by board area can benefit from consolidating several small programmable devices into this single TQFP package.
The primary PCB considerations are power integrity, decoupling, programming access, and signal-integrity control. Place the device-supply bypass capacitors close to its power pins, route the configuration interface away from high-current switching nodes, and use the pin descriptions in the manufacturer datasheet when assigning board signals. Verify every external pin against the 144-pin package drawing before fabrication.
This page combines device specifications, package details, practical implementation guidance, and a structured review of same-package upgrade options. It is designed to help engineers determine whether the XC2C256-6TQ144C matches the required logic capacity, timing, temperature grade, I/O count, and legacy-board footprint.

Applications typiques
XC2C256-6TQ144C convient pour 6 applications: Industrial Control and Automation Logic, Bus Arbitration and Interface Consolidation, Telecommunications Line-Card Control, Data-Acquisition Control Logic, Consumer Equipment and Peripheral Control, Protocol Bridging and Glue Logic.
Industrial Control and Automation Logic
The XC2C256-6TQ144C fits centralized machine-control logic because its 256 macrocells can implement state machines, interlocks, sequencing, and interface conditioning without a larger FPGA. Its 118 user I/O provide substantial connectivity for sensors, actuators, communication transceivers, and discrete control signals. The 5.7 ns maximum pin-to-pin delay supports deterministic short control paths, while the commercial 0°C to 70°C ambient grade is appropriate for controlled indoor equipment. Designers should retain timing margins for external transceivers and verify the implemented clock domains in the design tool.
Recommandé
Bus Arbitration and Interface Consolidation
The XC2C256-6TQ144C is useful for combining address decoding, bus arbitration, handshake conversion, and peripheral-select logic in a compact programmable-logic device. Its 118 user I/O can support multiple data, address, and control signals, while 256 macrocells provide enough architecture for concurrent logic functions. The 5.7 ns speed grade makes the device suitable for many short control intervals, but the external bus must not drive the CPLD beyond its specified I/O limits. Validate contention behavior, pull states, and timing across every bus master before production.
Recommandé
Telecommunications Line-Card Control
The XC2C256-6TQ144C can implement line-card timing, supervisory logic, alarm latches, and backplane control functions where deterministic package behavior and nonvolatile configuration are important. The 256-macrocell device offers more logic capacity than a small PAL while retaining the simple programming model associated with a CPLD. Its 118 I/O supports connections to transceivers, status indicators, and supervisory processors. For telecommunications equipment deployed outside controlled indoor environments, use an industrial-temperature grade and complete environmental, isolation, and safety qualification at the system level.
Recommandé
Data-Acquisition Control Logic
The XC2C256-6TQ144C is appropriate for coordinating multiplexers, sample counters, triggers, data latches, and communications formatting in a data-acquisition front end. The 118 user I/O can connect multiple converters and digital sensors, while the 256 macrocells accommodate parallel acquisition channels and supervisory state machines. The device-level 5.7 ns delay should not be treated as a complete acquisition-path timing specification because converter, routing, and inter-device delays must also be included. Use synchronous design rules and establish setup and hold margins in the implementation environment.
Recommandé
Consumer Equipment and Peripheral Control
The XC2C256-6TQ144C can consolidate key-sequence logic, display control, button decoding, peripheral selection, and status sequencing in consumer products. Its 144-pin TQFP package provides a defined footprint with 118 user I/O, while the nonvolatile configuration eliminates a separate boot-time configuration sequence after power is restored. The commercial temperature range covers many indoor product environments. Firmware updates and production programming should be planned with controlled access to the configuration interface, and unused pins must be terminated according to the device requirements.
Recommandé
Protocol Bridging and Glue Logic
The XC2C256-6TQ144C is well suited to protocol conversion, framing, parity generation, FIFO control, and asynchronous handshake bridging. Its 256 macrocells allow multiple independent logic blocks to be consolidated, while 118 I/O accommodate parallel interfaces to processors, transceivers, and memories. The device can preserve a legacy board's programmable-logic footprint when redesign would otherwise require replacing several smaller devices. Because each interface has distinct setup, hold, and voltage requirements, validate timing and I/O standards rather than assuming every pin combination is interchangeable.

Notes de conception
Use the 144-pin TQFP package drawing in AMD datasheet DS094 to establish pin 1 orientation, pad geometry, and the land pattern. The package is specified as 20 mm by 20 mm. Preserve access to the configuration and programming pins, keep the footprint free of exposed conductive features, and follow the manufacturer's PCB recommendations for thermal vias under the device. Because the XC2C256 family is legacy technology, verify footprint compatibility mechanically and electrically before releasing a new board.
Place the required supply bypass capacitors close to the corresponding power and ground pins, with short, low-inductance connections and a solid ground reference. Organize the layout so switching nodes and high-current return paths do not share narrow copper regions with configuration or I/O routing. The device is optimized for 1.8 V systems, but the exact operating limits, power sequencing, and supply combinations must be taken from the manufacturer electrical-characteristics tables rather than inferred from the general architecture.
Treat every connected user pin as part of a timed interface rather than assuming all paths meet the 5.7 ns device-level maximum. Establish setup and hold requirements for each external device, include routing and package delay in system timing, and use the implementation tool for final static timing analysis. For buses, terminate unused inputs and control contention before configuration. Configuration signals should be isolated from noisy external buses to prevent accidental reprogramming or invalid configuration states.
Do not substitute an XC2C256 package with fewer I/O solely because its macrocell count matches. Although variants such as VQFP-100 devices can provide the same 256 macrocells, their 100-pin packages have fewer user connections and are not board-compatible. Confirm the complete 144-pin assignment, speed grade, temperature suffix, commercial or extended-temperature requirement, and qualification status. A successful schematic equivalence does not by itself prove drop-in compatibility.
Informations de conformité
The manufacturer datasheet confirms the CoolRunner-II device family and package information, but no explicit RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status is stated for this exact ordering code.
