MPN： XC2C384-7PQ208C ✓ 啟用中XC2C384-7PQ208C 概覽
A CPLD is a type of programmable logic device that combines a large number of macrocells with a programmable interconnect fabric, sitting in the system hierarchy between simple SPLDs (such as GAL and PAL devices) and full FPGAs. Unlike SRAM-based FPGAs, CoolRunner-II CPLDs configure instantly at power-up from on-chip flash, making them voltage regulators of glue logic: they replace many discrete 74-series logic ICs, perform address decoding, bus interfacing, and state-machine control with zero external configuration storage.
Key features of the XC2C384-7PQ208C include its industry-leading 0.18 micron CMOS CPLD process, 7.1 ns pin-to-pin delay performance in the -7 speed grade, and quiescent current as low as 14 microamps, which makes it one of the lowest-power members of the programmable logic family. The 240 available user I/O provide high pin-count glue-logic integration, and the commercial temperature grade covers 0 C to +70 C.
Architecturally, the CoolRunner-II family uses a fast, deterministic interconnect that avoids the variable routing delays of FPGA fabrics, so timing closure is straightforward: the 7.1 ns pin-to-pin figure holds across typical designs. The 1.8V core optimization reduces dynamic power dramatically compared with earlier 3.3V CPLD generations, while I/O banks tolerate standard logic levels for mixed-voltage board integration.
Typical applications include address decoding and bus bridging in embedded systems, power-up configuration control for larger FPGAs, interface conversion between legacy and modern logic families, and portable or battery-powered designs where the 14 microamp standby current directly extends battery life.
Design consideration: assign unused I/O as grounded outputs or inputs with termination per the manufacturer datasheet guidelines, and verify I/O bank voltage compliance before mixing 3.3V and 1.8V signals on the same bank.
This page adds value beyond the manufacturer datasheet by synthesizing distributor availability, drop-in family alternatives with speed-grade trade-offs, and practical design notes in one place.

典型應用
XC2C384-7PQ208C 適用於 6 應用s: Address Decoding and Bus Glue Logic, FPGA Configuration and Power-Up Sequencing, Industrial Control and Automation, Portable and Battery-Powered Instruments, Communication and Networking Interface Cards, Test and Measurement Equipment.
Address Decoding and Bus Glue Logic
The XC2C384-7PQ208C excels as system glue logic for address decoding, chip-select generation, and bus interfacing in embedded processor designs. With 384 macrocells and 240 user I/O, a single PQ208 device can absorb the decoders, buffers, and handshaking registers that would otherwise occupy dozens of 74-series packages, shortening board routing and reducing BOM count. The 7.1 ns deterministic pin-to-pin delay of the -7 speed grade means a memory or peripheral chip-select asserted from an address bus settles well within typical SRAM and peripheral access-time budgets, and because CoolRunner-II interconnect delays are fixed by architecture, timing closure does not depend on fitter placement results. Use synchronous registered outputs where setup/hold budgets allow, and assign unused I/O per manufacturer guidelines for signal integrity.

FPGA Configuration and Power-Up Sequencing
In systems built around larger SRAM-based FPGAs, the XC2C384-7PQ208C is a natural configuration controller: it manages done-pin monitoring, reset distribution, configuration-mode straps, and power-good sequencing for multi-rail boards. The instant-on flash architecture means the CPLD's own control logic is active from the first microseconds of power-up - no configuration download delay - which is exactly the property a sequencer needs. Its 14 microamp quiescent draw adds negligible standby burden in systems that spend long periods in a low-power state, and the 1.8V-optimized core suits modern low-voltage rails. With 240 user I/O available, one device can also bridge the FPGA's configuration bank to LEDs, DIP switches, and board-management signals. Design the state machine so each rail's enable output is registered against a measured power-good input, and verify POR thresholds against the board's regulator specifications.
推薦
Industrial Control and Automation
Factory automation panels, motor-control interface boards, and PLC I/O modules use the XC2C384-7PQ208C to consolidate discrete control logic: interlocks, encoder quadrature decoding, PWM distribution, and fault-latching state machines. The 384 macrocells provide enough density for several independent functional blocks in one device, and the high 240-pin I/O count matches the dense terminal blocks typical of industrial I/O cards. The CoolRunner-II family's low and predictable pin-to-pin delay (7.1 ns in the -7 grade) supports fast protection paths - for example, gating a drive enable within nanoseconds of a fault input - without software latency in a supervising MCU. Its flash configuration survives power cycling and industrial EMI events without reconfiguration hardware. Note this commercial grade is rated 0 C to +70 C; for cabinets outside that envelope, select an industrial-grade variant of the family.

Portable and Battery-Powered Instruments
Handheld measurement and data-acquisition instruments benefit directly from the XC2C384-7PQ208C's power profile: 14 microamp typical quiescent current and a 1.8V-optimized 0.18 micron CMOS process give the lowest static draw in its programmable-logic class, so the CPLD does not erode battery budget during sleep periods. The 240 user I/O support dense front-end switching, range-selection relays, and display interface logic on a single device, while the 7.1 ns -7 speed grade handles fast trigger and gating paths that an MCU cannot service in time. The instant-on flash configuration keeps the instrument's power-up behavior deterministic - measurement paths are defined the moment rails stabilize, with no configuration boot delay to gate. Keep unswitched logic blocks in the low-power state via clock enables, and confirm I/O bank voltages against the instrument's 3.3V and 1.8V domains.
推薦
Communication and Networking Interface Cards
Line cards, protocol bridges, and network interface boards use the XC2C384-7PQ208C for PHY interfacing, status multiplexing, LED scanning, and backplane control-signal distribution. The 240 user I/O accommodate wide parallel status and control buses across multiple PHY and MAC devices, and the -7 speed grade's 7.1 ns pin-to-pin delay supports high-rate control handshaking on parallel interfaces. Because the device is fully reprogrammable via JTAG in-system, protocol or pin-assignment changes late in development or during field updates do not require a PCB respin - only a configuration-file update. The deterministic interconnect also simplifies timing analysis against PHY setup and hold requirements compared with an FPGA fabric. Decouple each supply pin per the manufacturer datasheet recommendation and keep configuration JTAG chains short for reliable boundary-scan manufacturing tests.
推薦
Test and Measurement Equipment
Bench instruments, logic fixtures, and automated-test fixtures use the XC2C384-7PQ208C for trigger generation, signal multiplexing, relay driver sequencing, and instrumentation handshaking. The 384 macrocells implement multi-channel timing generators and edge-detection state machines, while 240 user I/O match the channel counts of switching matrices and connector blocks. The fixed 7.1 ns pin-to-pin delay makes trigger-to-output latency calculable at design time - an important property for calibrated instruments where timing skew must be budgeted across channels - and flash configuration ensures the instrument is functional immediately at power-on with zero boot delay. JTAG boundary scan on the device supports board-level interconnect testing during production. For analog sections, keep CPLD outputs away from sensitive front ends and use series termination to limit switching noise coupling.

主要差異化特點
- Fastest speed grade in the XC2C384 PQ208 family (對比XC2C384-10PQG208C)
- Industry-leading low standby power (對比XC2C384-10PQ208C)
- High I/O density in one footprint (對比XC2C384-7PQG208C)
設計說明
Decouple every VCCINT and VCCIO pin pair of the PQ208 package with at least 100 nF ceramic capacitors placed within a few millimeters of the pins, plus bulk capacitance (10 uF class) at the board level per the CoolRunner-II power guidelines in the manufacturer datasheet. The core runs at 1.8V and is optimized for low dynamic current, but simultaneous switching of many of the 240 I/O can inject ground bounce; distribute ground pins and avoid grouping all fast-switching outputs in one bank when possible. Confirm exact rail voltages and sequencing requirements from the datasheet before board bring-up.
With 240 user I/O, output loading dominates AC behavior. Add 22-33 ohm series resistors on fast outputs driving long traces or cables to damp ringing, and use the -7 grade's 7.1 ns pin-to-pin delay as the worst case for setup calculations - do not assume faster edges from simulation alone. Keep JTAG chain traces short and properly terminated for reliable in-system programming and boundary-scan test in production. Verify I/O bank voltage compatibility before mixing 3.3V and 1.8V signaling on the same bank.
The most common mistake with this part is ordering the wrong suffix: the C-suffix non-G variant contains lead and is non-RoHS, so compliance-critical products should order XC2C384-7PQG208C instead. Another pitfall is substituting the -10 speed grade (XC2C384-10PQG208C) without re-running static timing - paths designed against the 7.1 ns budget will fail at the 10 ns class. Finally, unused I/O must be assigned per manufacturer guidelines; floating inputs increase noise susceptibility and current draw.
合規資訊
The non-G suffix (PQ208C) is listed as containing lead and non-RoHS-compliant on comparison listings; the XC2C384-7PQG208C is the Pb-free/RoHS-compliant counterpart. Commercial temperature grade (0-70 C), not AEC-Q100 relevant.
