A complex programmable logic device, or CPLD, is a programmable-logic semiconductor used to implement fixed digital functions without changing the physical PCB. In the broader hierarchy, a CPLD is a programmable logic device, a member of the FPGA and CPLD category, and a type of semiconductor. CoolRunner-II devices combine nonvolatile configuration storage with programmable logic blocks, allowing a loaded design to operate without an external configuration PROM after programming.
Key features of the XC2C32A include 32 macro cells, approximately 750 gates, CMOS operation at 1.8 V, and low quiescent current of as low as 12 µA. Its fast pin-to-pin logic performance makes it suitable for control logic, state machines, bus arbitration, interface adaptation, and startup sequencing. The device is optimized for 1.8 V systems, helping simplify connection to modern low-voltage processors, FPGAs, and memory devices.
The listed internal frequency of 450 MHz describes the device’s internal timing capability rather than a guaranteed system-clock rate. External setup, hold, interconnect, and I/O timing still determine achievable board-level performance. A listed 4 ns propagation delay applies to a characterized logic path, while 3.0 ns is the fastest stated pin-to-pin logic delay; these figures should not be treated as identical timing conditions.
Typical uses include portable equipment, industrial control modules, embedded systems, and general-purpose glue logic. Its nonvolatile configuration behavior supports deterministic power-up operation, while its relatively small 32-macro-cell array is most effective when the required Boolean logic is modest and deterministic.
Designers should verify every signal against the DS310 pin table, confirm the selected system voltage and I/O standards, and avoid relying on the maximum internal frequency as an unconditional peripheral operating rate. Toolchain and programming-file compatibility must also be checked before transferring an existing CPLD design to this exact ordering code.
This page consolidates manufacturer and distributor information, verified source links, practical design guidance, and clearly qualified replacement analysis. It also distinguishes documented performance claims from unavailable electrical details, helping engineers make a more reliable selection without introducing unverified specifications.

典型应用
XC2C32A-6VQ44I 适用于 6 应用s: Industrial Control and State-Machine Logic, Embedded Interface and Bus Glue Logic, Portable and Battery-Powered Equipment, Power-Up Sequencing and Reset Control, Data Acquisition and Signal Conditioning, Communications and Network Interface Support.
Industrial Control and State-Machine Logic
The XC2C32A-6VQ44I fits deterministic industrial control blocks that combine multiple Boolean equations, counters, and sequencing states without requiring a larger FPGA. Its 32 macro cells and 750 gates provide useful logic density for supervisory controllers, while the listed 4 ns propagation delay and pin-to-pin delays as fast as 3.0 ns support short control paths. The industrial-temperature ordering suffix is appropriate when the design environment is specified as industrial. Because the device uses nonvolatile configuration, the controller can begin its programmed sequence after power-up. Designers should calculate worst-case setup and hold margins using the -6 timing tables in AMD DS310 rather than treating the listed 450 MHz internal frequency as a universal clock guarantee.
推荐
Embedded Interface and Bus Glue Logic
The XC2C32A-6VQ44I can implement bus arbitration, signal translation, data-routing, and protocol-adaptation logic between a 1.8 V processor and external peripherals. Its 33 user I/O pins provide a practical interface count, while the 32-macro-cell array is sufficient for multiple small state machines and address decode functions. The -6 grade offers more timing margin than slower family members when the processor interface is operated at a moderate clock. The nonvolatile configuration also avoids a continuous external configuration-device requirement. Exact I/O direction, voltage compatibility, and timing must be checked against the 44-pin DS310 pin table, and unused pins should be handled according to the manufacturer’s recommended termination and configuration guidance.
推荐
Portable and Battery-Powered Equipment
The XC2C32A-6VQ44I suits portable equipment requiring low-voltage logic with low standby demand. The device is optimized for 1.8 V systems, uses 0.18 µm CMOS technology, and has a listed quiescent current as low as 12 µA. Those characteristics are useful for battery-powered instrumentation, portable test equipment, and compact control modules that spend significant time inactive. The nonvolatile configuration eliminates a continuously powered external configuration PROM, which can improve system-level standby behavior. The 12 µA value must not be interpreted as the active current; I/O loading, operating frequency, and active-state consumption require separate verification. Thermal and battery-life calculations should use the complete DS310 current tables and the actual external load.
推荐
Power-Up Sequencing and Reset Control
The XC2C32A-6VQ44I is well suited to power sequencing because its nonvolatile configuration is retained and its 32 macro cells can implement deterministic state machines. The device can combine power-good inputs, delay counters, reset generation, and interlock outputs in one compact logic block. The listed 4 ns propagation delay is relevant to short sequencing paths, while the -6 grade helps preserve margin where multiple logic levels feed a control signal. Because power sequencing is safety- and timing-critical, engineers must validate every path with external resistor, capacitor, and rise-time assumptions rather than relying only on nominal device timing. AMD DS310 should be used for pin assignments, timing limits, and recommended power configuration behavior.
推荐
Data Acquisition and Signal Conditioning
The XC2C32A-6VQ44I can implement front-panel control, digital filtering, channel selection, trigger coordination, and status decoding around data-conversion systems. A 32-macro-cell CPLD is most useful when the signal path requires deterministic short control loops rather than extensive data storage. The documented 3.0 ns fastest pin-to-pin logic delay and 4 ns propagation-delay listing can support fast trigger or multiplex-selection functions, although external device timing remains part of the complete path. The 1.8 V optimization allows integration with compatible converters and processors. Engineers must ensure that every connected data-conversion device uses compatible voltage levels and must confirm that the 44-pin device provides the required data, clock, and control pins before committing the design.
推荐
Communications and Network Interface Support
The XC2C32A-6VQ44I can support fixed-function communications logic such as frame synchronization, interrupt combination, FIFO-status decoding, and bus arbitration. Its fast documented timing is useful for synchronizing short control paths around network interfaces, while 33 user I/O pins offer sufficient connectivity for compact implementations. The nonvolatile architecture allows programmed protocols to remain available immediately after power restoration. This role should remain limited to logic that fits within 32 macro cells and approximately 750 gates; larger datapaths belong in an FPGA or dedicated interface controller. Signal-integrity and timing reviews should include the physical connection to the communications device, clock source, pin assignments, and any voltage-level translation. The DS310 I/O and timing tables remain the controlling references.

设计说明
Do not treat the listed 450 MHz internal frequency as a guaranteed I/O operating frequency. The source also lists 200 MHz for the device and separately identifies 4 ns propagation delay and pin-to-pin logic delays as fast as 3.0 ns, which represent different timing contexts. Use the AMD DS310 -6 timing tables, including setup, hold, and external clock requirements, to close every path. Also verify the exact 44-pin ordering table because third-party snippets in the supplied results mixed the target’s 44-pin VTQFP configuration with a 56-pin CSP description.
Estimated: the documented quiescent current of 12 µA at 1.8 V corresponds to a no-load quiescent power of about 21.6 µW, calculated as 1.8 V × 12 µA. This is not an estimate of active consumption and excludes external I/O loading and internal switching activity. Power-budget portable designs using the full DS310 current tables and the operating frequency. Do not size a regulator only from the 12 µA figure, because output current and dynamic demand can be substantially higher.
Preserve the manufacturer’s recommended power, ground, and decoupling topology for the selected 44-pin package. Place local bypass capacitors close to the device supply pins and provide a low-impedance ground path for switching outputs. Keep clock and high-speed state-machine outputs away from sensitive analog inputs where practical. Before layout release, compare the mechanical drawing and pin numbering in AMD DS310, especially when considering an XC2C32A-6VQG44I or other ordering-code substitute.
合规信息
The supplied manufacturer and distributor snippets do not explicitly state RoHS, REACH, AEC-Q100, lead-free, halogen-free, or conflict-minerals status. Compliance must be confirmed for the exact ordering code and date of manufacture with AMD or the authorized distributor.
