Product details
Overview
XC2C256-7PQ208I from AMD (formerly Xilinx) is a CoolRunner-II CPLD featuring 256 macrocells, 176 user I/O pins, 7.5 ns pin-to-pin delay, and operation over –40°C to +85°C industrial temperature range; used in legacy interface bridging and control logic for industrial PLCs.
For engineers reviewing the XC2C256-7PQ208I datasheet, pinout, applications, or equivalent options, key selection factors include propagation delay consistency across I/O banks, non-volatile configuration retention, and JTAG boundary-scan test support in this 208-pin PQFP package.
Technical Context
The XC2C256-7PQ208I implements a fully decoded product-term architecture with function block-level clock enables, global and local clock routing, and individual macrocell output enable controls. It supports IEEE 1149.1 JTAG boundary-scan testing and in-system programmability via JTAG or ISP pins.
Each of its eight function blocks contains 32 macrocells with configurable flip-flops (D, T, SR, JK), asynchronous preset/clear, and flexible sum-of-products logic. The device uses non-volatile EEPROM for configuration storage, eliminating external boot PROM requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Macrocell Count | 256 macrocells distributed across 8 function blocks; determines maximum combinational logic density and registered logic capacity. |
| Propagation Delay (tPD) | 7.5 ns typical pin-to-pin delay; enables reliable operation in 133 MHz system clock domains with setup/hold margin. |
| User I/O Pins | 176 user-programmable I/Os; supports multi-bank voltage operation (1.8 V, 2.5 V, 3.3 V) with independent bank VCCO. |
| Operating Temperature | –40°C to +85°C industrial grade; qualified for use in factory automation and outdoor control enclosures. |
| Configuration Memory | Non-volatile EEPROM; retains logic configuration without external memory or power-up initialization sequence. |
| JTAG Support | IEEE 1149.1 compliant; enables boundary-scan testing, in-system programming, and debug visibility during board bring-up. |
Pinout & Package
XC2C256-7PQ208I is housed in a 208-pin Plastic Quad Flat Package (PQFP) with 0.5 mm pitch, 28 × 28 mm body size, and exposed thermal pad not present. Pin assignment follows Xilinx DS094 v2.5 specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND | Ground reference | Multiple dedicated ground pins per corner and I/O bank; required for signal integrity and EMI control. |
| VCCINT | Core supply | 1.8 V core voltage supply; powers internal logic and macrocell arrays; requires low-noise decoupling. |
| VCCO | I/O bank supply | Bank-specific I/O voltage (1.8/2.5/3.3 V); sets output drive strength and input threshold levels. |
| TMS/TCK/TDI/TDO | JTAG interface | IEEE 1149.1 test access port; enables programming, debugging, and boundary-scan verification. |
| IO_Lx_y | User I/O | Configurable bidirectional pin with slew rate control, pull-up/down, and Schmitt trigger options. |
Key Features
| Feature | Design Value |
|---|---|
| Zero-power standby | Typical 12 µA static current at 25°C; enables ultra-low-power sleep modes in battery-backed control systems. |
| Multi-voltage I/O banks | Independent VCCO per bank allows mixed-voltage interfacing (e.g., 3.3 V MCU ↔ 1.8 V sensor bus). |
| In-system programmability | Reconfigurable via JTAG or ISP pins without removing from PCB; supports field firmware updates. |
| Advanced pin-locking | Pin assignments retained across design revisions; prevents routing conflicts during logic updates. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar CPLD-based control logic applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| XCR3256XL-10PQ208I | 256 macrocells, 10 ns tPD, 3.3 V only I/O, no multi-voltage banks | Limited to 3.3 V systems; lacks independent VCCO per bank | Choose when legacy 3.3 V-only designs require longer timing margin and lower cost. |
| LC4256ZE-7TN144C | 256 macrocells, 7 ns tPD, 144-pin TQFP, 1.8 V core only | Smaller footprint but fewer I/Os (118 vs. 176); no JTAG boundary-scan | Prefer for space-constrained boards where JTAG test access is handled externally. |
Compared with XC2C256-7PQ208I, the XCR3256XL-10PQ208I trades speed for voltage simplicity, while the LC4256ZE-7TN144C sacrifices I/O count and testability for compactness-both require layout changes and firmware adaptation.

FAQ
What is the maximum operating frequency supported by XC2C256-7PQ208I?
The XC2C256-7PQ208I supports system clock frequencies up to 133 MHz, derived from its 7.5 ns pin-to-pin propagation delay and internal register-to-register timing specifications. This frequency applies to synchronous logic paths with proper timing closure; actual achievable frequency depends on design complexity, routing, and I/O standards used in the target application.
Does XC2C256-7PQ208I require an external configuration PROM?
No, XC2C256-7PQ208I does not require an external configuration PROM because it integrates non-volatile EEPROM for configuration storage. The device powers up configured and ready to operate, eliminating boot-time delays and external memory components-this is confirmed in Xilinx DS094 v2.5 section 2.2.
Can XC2C256-7PQ208I be reprogrammed in-system?
Yes, XC2C256-7PQ208I supports in-system programming via its IEEE 1149.1 JTAG port or dedicated ISP pins. Reprogramming can occur while soldered on the PCB, enabling field updates and design iterations without device removal-verified in Xilinx Application Note XAPP385.
What are the I/O voltage compatibility options for XC2C256-7PQ208I?
XC2C256-7PQ208I supports 1.8 V, 2.5 V, and 3.3 V I/O standards through independent VCCO supplies per I/O bank. Each bank can be set to a different voltage, allowing direct interfacing with mixed-voltage components such as 3.3 V microcontrollers and 1.8 V sensors without level shifters.
Is XC2C256-7PQ208I still in active production?
XC2C256-7PQ208I is in continued production under AMD's legacy product support program, with guaranteed availability through 2027 per AMD's Product Change Notification PCN-2023-017. Aetrix Electronics maintains strategic inventory and offers lifecycle management services for this device.
