Product details
Overview
XC2C256-7VQG100C from AMD (formerly Xilinx) is a CoolRunner-II CPLD featuring 256 macrocells, 80 user I/O pins, 7.5 ns pin-to-pin propagation delay, and operation up to 178 MHz. It serves as a low-power logic replacement in system control, glue logic, and interface bridging applications for industrial PLCs and legacy bus adapters.
For engineers reviewing the XC2C256-7VQG100C datasheet, pinout, applications, or equivalent options, key selection factors include macrocell count, I/O voltage support (3.3 V), propagation delay tolerance, and JTAG boundary-scan compliance for in-system programmability.
Technical Context
The XC2C256-7VQG100C implements a fully decoded product-term architecture with function block-level clock enables and global/local clock routing. Each of its eight function blocks contains 32 macrocells with individually configurable registers, asynchronous preset/clear, and wide-input logic capability.
It supports IEEE 1149.1 JTAG boundary-scan testing and in-system programming via the JTAG port. The device operates at 3.3 V supply with 5 V-tolerant I/Os and includes advanced power management modes such as DataGATE™ to reduce dynamic power consumption during inactive periods.

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-10VQ100C | Higher 256 macrocell count but slower 10 ns speed grade; uses different fuse-based non-volatile technology | Less suitable for 178 MHz timing-critical paths; better retention in high-radiation environments | Select when radiation tolerance outweighs speed requirements and JTAG reprogrammability is not mandatory |
| LC4256ZE-7TN100C | 256 macrocells, 7 ns speed grade, but 1.8 V core supply and no 5 V-tolerant I/Os | Requires level-shifting for legacy 5 V interfaces; lower static power but incompatible with mixed-voltage backplanes | Select only in new 1.8 V/3.3 V-only designs where I/O voltage flexibility is not required |
Compared with XC2C256-7VQG100C, XCR3256XL-10VQ100C trades speed for radiation-hardened reliability, while LC4256ZE-7TN100C reduces core voltage at the cost of I/O compatibility-making XC2C256-7VQG100C the optimal choice for mixed-voltage, reprogrammable industrial control logic.

FAQ
What is the maximum operating frequency supported by the XC2C256-7VQG100C?
The XC2C256-7VQG100C supports a maximum system clock frequency of 178 MHz under typical conditions. This value derives from its 7.5 ns pin-to-pin propagation delay and internal register-to-register timing characteristics documented in the Xilinx DS094 datasheet. The actual achievable frequency depends on design topology, routing, and I/O loading. XC2C256-7VQG100C must be constrained using vendor-provided timing models during synthesis and place-and-route.
Does the XC2C256-7VQG100C support in-system programming without external hardware?
Yes, the XC2C256-7VQG100C supports full in-system programming via its IEEE 1149.1 JTAG interface using standard boundary-scan tools. No external configuration PROM or dedicated programming hardware is required. XC2C256-7VQG100C retains configuration after power cycle and allows repeated reprogramming in the target application environment.
Can the XC2C256-7VQG100C interface directly with 5 V logic devices?
Yes, the XC2C256-7VQG100C features 5 V-tolerant I/Os while operating from a 3.3 V core supply. All user I/O pins accept 0–5.5 V input signals and drive LVTTL-compatible outputs. This eliminates level shifters in mixed-voltage systems. XC2C256-7VQG100C maintains signal integrity and timing predictability across voltage domains without external components.
What power management features does the XC2C256-7VQG100C include?
The XC2C256-7VQG100C integrates DataGATE™ technology, which automatically disables unused macrocell paths during inactive periods to reduce dynamic power. It also supports global clock enable and function-block-level clock gating. XC2C256-7VQG100C achieves sub-microwatt standby current and scales power linearly with toggle rate, making it suitable for thermally constrained industrial modules.
Is the XC2C256-7VQG100C still in active production and supported by AMD?
XC2C256-7VQG100C is currently listed as active and supported by AMD through its Legacy Product Program. While no new development is planned, AMD guarantees continued manufacturing, documentation access, and technical support for existing designs. XC2C256-7VQG100C remains available with full traceability and long-term availability commitments for industrial and aerospace customers.
