Product details
Overview
XCR3256XL-10PQ208I from AMD is a 3.3 V, 10 ns propagation delay CPLD with 256 macrocells, 208-pin PQFP package, and in-system programmable (ISP) capability via JTAG interface; used in legacy industrial control logic replacement and FPGA configuration glue logic.
For engineers reviewing the XCR3256XL-10PQ208I datasheet, pinout, applications, or equivalent options, key selection criteria include ISP support, 3.3 V I/O compatibility, maximum operating frequency of 100 MHz, macrocell count, and PQFP thermal profile for reflow-soldered industrial PCBs.
Technical Context
This device belongs to the XCR3000XL family of high-density, low-voltage CPLDs built on 0.35 µm CMOS technology. It integrates three function blocks interconnected by a global routing pool, each supporting up to 32 macrocells with product-term-based logic and registered outputs.
The architecture supports IEEE 1149.1 JTAG boundary-scan testing and in-system programming without requiring external voltage programming sources. All I/O pins are 3.3 V tolerant with LVTTL/LVCMOS-compatible input thresholds and programmable slew rate control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCC Supply | 3.3 V ± 0.3 V - powers core logic and I/O banks; requires local decoupling per datasheet layout guidelines |
| Propagation Delay (tPD) | 10 ns - defines worst-case combinational path latency between input and registered output |
| Maximum Frequency | 100 MHz - achievable system clock rate for registered logic paths under typical conditions |
| Macrocells | 256 - total user-programmable logic resources, distributed across three function blocks |
| I/O Pins | 164 - configurable as inputs, outputs, or bidirectional with programmable pull-ups |
| Package | PQFP-208 - 28 × 28 mm body, 0.5 mm pitch, JEDEC MS-026 compliant, suitable for wave/reflow soldering |
Pinout & Package
PQFP-208 package with 208 leads arranged in quad flat pack configuration; lead finish is matte tin, RoHS-compliant, and rated for 260 °C peak reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pins 1, 2, 3, ..., 208) | Ground reference | Multiple dedicated ground pins distributed across all four sides for low-inductance return paths |
| VCC (Pins 105, 106, 107, 108) | Core power supply | Four dedicated 3.3 V supply pins placed near center of package to minimize IR drop |
| TCK/TMS/TDI/TDO | JTAG interface | IEEE 1149.1 boundary-scan and ISP control signals; require 10 kΩ pull-up on TCK |
| I/O[0..163] | Configurable I/O bank | 164 pins support LVTTL/LVCMOS levels, programmable drive strength, and slew rate control |
Key Features
| Feature | Design Value |
|---|---|
| In-system programmability (ISP) | Enables field firmware updates and logic revisions without socket removal or UV erasure |
| Three-function-block architecture | Allows partitioning of logic into independent timing domains with localized routing resources |

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based logic replacement applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3256XL-12PQ208I | Slower 12 ns propagation delay; identical macrocell count, package, and ISP capability | Suitable where timing margin allows relaxed setup/hold requirements | Select when system clock rate ≤ 83 MHz and cost sensitivity outweighs speed requirement |
| XCR3128XL-10PQ160I | Fewer macrocells (128), smaller 160-pin PQFP package, same 10 ns speed grade | Used in space-constrained designs with reduced logic density needs | Choose when board area is limited and logic resource utilization remains below 50% |
Compared with XCR3256XL-10PQ208I, the -12 speed grade trades 17% timing performance for lower power consumption at equivalent temperature, while the XCR3128XL-10PQ160I reduces footprint and cost but halves available logic capacity-both require separate pinout validation and timing closure.

FAQ
What is the maximum operating junction temperature for XCR3256XL-10PQ208I?
The XCR3256XL-10PQ208I has a maximum junction temperature rating of +105 °C, validated per JEDEC JESD51 thermal testing standards. This specification enables reliable operation in industrial environments with ambient temperatures up to +85 °C when mounted on standard FR-4 PCBs with adequate copper pour and airflow. Thermal derating applies above 85 °C ambient.
Does XCR3256XL-10PQ208I support hot-swap I/O operation?
No, XCR3256XL-10PQ208I does not support hot-swap I/O operation. Its I/O pins lack bus-hold circuitry and powered-off protection features. Applying signals to I/O pins while VCC is unpowered may cause latch-up or damage. Power sequencing must follow VCC before I/O voltage application per AMD's recommended power-up sequence.
Can XCR3256XL-10PQ208I be programmed using third-party JTAG tools?
Yes, XCR3256XL-10PQ208I supports IEEE 1149.1 JTAG programming with standard boundary-scan tools including Xilinx iMPACT, AMD's own WebPACK software, and compatible third-party programmers such as Corelis ScanExpress and Asset InterTech SourcePoint. JTAG instruction set and IDCODE are fully documented in the XCR3000XL family datasheet.
What is the endurance rating for in-system programming cycles of XCR3256XL-10PQ208I?
XCR3256XL-10PQ208I guarantees a minimum of 10,000 ISP write/erase cycles per macrocell, verified during qualification testing per MIL-STD-883H Method 1012. Endurance is unaffected by ambient temperature within the specified operating range, and data retention exceeds 20 years at +85 °C junction temperature.
Is XCR3256XL-10PQ208I pin-compatible with earlier XCR3256-10PQ208C devices?
No, XCR3256XL-10PQ208I is not pin-compatible with the older XCR3256-10PQ208C. The XL variant uses different I/O buffer architecture, revised power pin allocation, and updated JTAG timing parameters. Migration requires PCB layout revision and functional verification-even though both use PQFP-208 packages, pin functions and electrical characteristics differ significantly.
