XC2C384-7TQ144C - 9K Gate 1.8V CPLD TQFP-144 | AMD/Xilinx
N.º da peça: XC2C384-7TQ144C ✓ AtivoXC2C384-7TQ144C Visão geral
A CPLD is a class of programmable logic device that sits between SPLDs (such as GAL/PAL devices) and FPGAs in the programmable-logic hierarchy. CPLDs use a macro-cell-based architecture with a deterministic, fully-connected programmable interconnect, which means every signal path has a fixed, predictable delay. This makes CPLDs the preferred choice for glue logic, state machines, bus interfacing, power-up sequencing and address decoding, where pin-to-pin timing consistency matters more than raw gate count.
Key features of the XC2C384-7TQ144C include its 1.8V supply optimization, which dramatically lowers dynamic power compared to 3.3V and 5V CPLD families, its 0.18-micron CMOS process that yields the industry-fastest 7.1 ns pin-to-pin delays for a low-power CPLD, and an ultra-low 14 uA quiescent current that suits battery-powered and always-on designs. The device offers up to 240 user I/O pins, giving designers extensive pin availability in a 0.5 mm-pitch 144-lead TQFP footprint.
Architecturally, CoolRunner-II macro cells combine a programmable AND/OR logic array with configurable registers, supporting combinational and sequential functions per cell. The family is programmed via industry-standard JTAG and is supported by the AMD/Xilinx ISE design suite for synthesis, fitting and in-system programming.
Typical applications include bus-interface translation and control, microprocessor glue logic, industrial control sequencing, communications line-card management and replacing multiple discrete logic devices to reduce board area and BOM count.
For design, note that 1.8V I/O standards apply - confirm level compatibility with 3.3V host devices before committing the board, and follow the manufacturer datasheet for JTAG programming-chain requirements.

Aplicações típicas
XC2C384-7TQ144C é adequado para 6 aplicaçãos: Microprocessor Glue Logic, Bus Interface Translation and Control, Industrial Control Sequencing, Power-Up Sequencing and Reset Management, Communications Line-Card Logic, Discrete Logic Consolidation.
Microprocessor Glue Logic
The XC2C384-7TQ144C consolidates address decoding, chip-select generation, read/write control and wait-state logic around embedded processors into one 384-macro-cell device. Its deterministic 7.1 ns pin-to-pin delay guarantees that decode timing is identical on every path, which is essential when memory chips have tight access-window requirements. Running from 1.8 V with 14 uA quiescent current, it replaces dozens of 74-series devices, cutting board area and BOM count while improving reliability. With 240 user I/Os in TQ144, wide 16-bit and 32-bit buses can be managed from a single package, and JTAG in-system programming lets control logic be updated during manufacturing or field service without board rework.
Recomendado
Bus Interface Translation and Control
Bridging legacy 3.3V or 5V buses to modern 1.8V logic is a classic CoolRunner-II task. The XC2C384-7TQ144C implements bidirectional transceivers, direction latches, byte-swap logic and handshake state machines across its 240 user I/O pins. The 217 MHz toggle capability supports fast synchronous buses, while deterministic macro-cell timing lets designers certify setup and hold margins analytically rather than through timing closure iterations. Low 1.8 V core operation keeps interface power low, important in dense line cards. Because configuration is retained through power cycles with instant-on operation, the interface is active immediately at system reset, satisfying host controllers that sample the bus early in boot.
Recomendado
Industrial Control Sequencing
In industrial automation panels, the XC2C384-7TQ144C executes deterministic sequencing of actuators, interlocks and safety handshake logic. The CPLD architecture provides fixed 7.1 ns pin-to-pin delays, so state transitions occur with predictable timing regardless of logic placement - a property relay replacements and microcontroller software loops cannot guarantee. The commercial 0 to +70 C rating covers standard cabinet environments, and the 1.8 V supply with 14 uA standby supports always-on monitoring functions. JTAG field reprogramming allows sequence changes to be applied during maintenance windows. Designers typically pair the CPLD with a supervisory device to enforce clean power-up of the sequencing logic.
Recomendado
Power-Up Sequencing and Reset Management
Multi-rail systems need ordered power-up: the XC2C384-7TQ144C monitors supply-good signals and gates enable outputs in the required order with hard-wired deterministic timing. Its instant-on flash-backed configuration means the sequencing logic is live within nanoseconds of power arrival - no configuration download delay as with SRAM FPGAs. With 384 macro cells, designers can encode multiple sequencing profiles selected by board strapping options. Quiescent current of 14 uA keeps the sequencing function invisible to overall standby power budgets in battery and energy-harvesting equipment. Output enables can also implement hot-swap and brownout hold-off behavior across the 240 available I/O pins.
Recomendado
Communications Line-Card Logic
Telecom and datacom line cards use the XC2C384-7TQ144C for frame-sync generation, HDLC-like framing assist, LED/status multiplexing and slot-address decoding across backplane connectors. The 217 MHz family toggle rate and 7.1 ns pin-to-pin delay comfortably handle 8-bit parallel control buses at standard line-card clock rates, while deterministic timing simplifies timing-budget sign-off across a multi-vendor card set. The 240 user I/Os of the TQ144 package interface to backplane connectors, front-panel indicators and serial transceivers simultaneously. Low 1.8 V operation reduces per-card power, an important metric when cards are deployed in hundreds-of-slot shelves.
Recomendado
Discrete Logic Consolidation
A frequent redesign driver: replacing 30-60 TTL/CMOS SSI/MSI packages (counters, latches, decoders, comparators) with one XC2C384-7TQ144C. The 384 macro cells provide ample capacity, and the 0.18 um CMOS process keeps power far below bipolar-era discrete logic despite higher integration. Board area shrinks dramatically, assembly cost drops, and reliability improves because inter-chip failures disappear. Deterministic delays often make consolidated designs faster than the original discrete chain. Because the TQ144 footprint is shared across CoolRunner-II densities (XC2C256/XC2C384/XC2C512), a consolidation design can migrate density later without PCB respin - a meaningful hedge against scope growth.

Notas de projeto
The XC2C384-7TQ144C runs from a single 1.8 V rail. Estimate dynamic power as P ≈ C·V²·f·N, where N is the number of simultaneously switching outputs - dynamic power rises quickly with I/O toggle rate and load capacitance, so derate designs toggling many outputs near the 217 MHz family maximum. Decouple with at least 100 nF ceramic per supply pin group plus bulk capacitance per the manufacturer datasheet recommendations, placed within a few millimeters of the pins. The 14 uA quiescent figure applies at standby; power budget reviews must use dynamic estimates for active operation.
The 1.8 V I/O must be level-checked against 3.3 V host devices before finalizing the schematic - most 3.3 V outputs will overdrive 1.8 V inputs beyond recommended limits, so plan series limiting or level translators where rail domains differ. Series source termination (typically 22-33 ohm) on fast outputs driving ribbon cable or long traces will control overshoot and ground bounce. The CoolRunner-II datasheet provides per-drive-strength output impedance; use it when calculating reflection coefficients for your trace geometry.
Two frequent mistakes with CoolRunner-II designs: (1) underestimating macro-cell usage - a 384-macro-cell device may not fit a design that 'looks' small because wide decoders and registered buses consume multiple cells per output; run the ISE fitter early to confirm fit before committing the PCB. (2) Substituting a -10 grade part for the -7 without re-running static timing - the 7.1 ns to 10 ns difference can break marginal decode windows. Also remember the commercial 0 to +70 C rating: extended-temperature designs require the I-grade variant, which has a different ordering code.
