Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based logic control applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3256XL-10PQ208C | 10 ns propagation delay, same macrocell count and package-higher speed grade with tighter timing margin. | Suitable for 100 MHz+ clock domains where setup/hold timing is critical. | Select when design requires sub-12 ns path delays and has verified timing slack at 3.3 V. |
| XC95288XL-10TQ144I | 288 macrocells, 144-pin TQFP, 10 ns delay-higher density but fewer I/O pins and different footprint. | Better for logic-intensive tasks with limited I/O needs; not drop-in compatible due to pin count and package mismatch. | Choose when macrocell count is prioritized over I/O count and board layout allows TQFP-144 rework. |
Compared with XCR3256XL-12PQ208C, the -10PQ208C offers faster timing at identical packaging, while the XC95288XL-10TQ144I trades I/O count for macrocell density and requires PCB redesign-making the XCR3256XL-12PQ208C optimal for I/O-rich, timing-constrained industrial control.

FAQ
What is the maximum operating frequency supported by the XCR3256XL-12PQ208C?
The XCR3256XL-12PQ208C guarantees a 12 ns pin-to-pin propagation delay, enabling reliable operation in synchronous logic designs up to 83 MHz. Actual achievable frequency depends on internal routing, fan-out, and clock skew-but the device is characterized and tested to meet this timing spec across the full commercial temperature range.
Does the XCR3256XL-12PQ208C require an external configuration PROM?
No. The XCR3256XL-12PQ208C integrates on-chip EEPROM for configuration storage, eliminating the need for external PROM. This allows instant-on operation after power-up and simplifies system design by reducing component count and board space requirements for the XCR3256XL-12PQ208C.
Is the XCR3256XL-12PQ208C compatible with 5 V tolerant I/Os?
No. The XCR3256XL-12PQ208C is a 3.3 V-only device with I/Os rated for 3.3 V LVTTL/LVCMOS signaling. Its inputs are not 5 V tolerant, and applying 5 V may damage the device. Level-shifting circuitry is required when interfacing with 5 V systems using the XCR3256XL-12PQ208C.
Can the XCR3256XL-12PQ208C be reprogrammed in the system?
Yes. The XCR3256XL-12PQ208C supports IEEE 1149.1 JTAG-based in-system programmability (ISP), allowing full configuration updates, debugging, and boundary-scan testing without removing the device from the PCB-critical for field upgrades and validation of the XCR3256XL-12PQ208C.
What thermal considerations apply to the XCR3256XL-12PQ208C in continuous operation?
The XCR3256XL-12PQ208C is specified for 0°C to +70°C ambient operation with JEDEC JESD51-2 compliant thermal characterization. Its 208-pin PQFP package dissipates heat effectively under typical industrial loads; no heatsink is required unless ambient exceeds 60°C or power dissipation exceeds 1.2 W-verified in thermal simulations for the XCR3256XL-12PQ208C.
