Product details
Overview
XC2C256-6FT256C from AMD (formerly Xilinx) is a CoolRunner-II CPLD featuring 256 macrocells, 212 user I/O pins, 6.7 ns maximum pin-to-pin delay, and operation up to 200 MHz. It implements synchronous logic in low-power, high-speed control applications such as address decoding and bus interfacing.
For engineers reviewing the XC2C256-6FT256C datasheet, pinout, applications, or equivalent options, key selection criteria include propagation delay, I/O count, supply voltage tolerance, JTAG programming support, and in-system programmability for field updates.
Technical Context
The XC2C256-6FT256C uses a fully decoded product-term architecture with function generators, macrocells, and global routing resources. It supports IEEE 1149.1 JTAG boundary-scan testing and in-system programming via the JTAG port.
Its logic array blocks (LABs) deliver deterministic timing with fixed interconnect delays. The device operates from a single 1.8 V core supply and supports 3.3 V or 2.5 V I/O standards with programmable slew rate and drive strength per bank.

FAQ
What is the operating temperature range for XC2C256-6FT256C?
The XC2C256-6FT256C is rated for commercial temperature operation from 0 °C to +70 °C. This range supports deployment in office-based test equipment and non-extreme industrial enclosures. The device's low-power architecture minimizes self-heating, helping maintain stability near the upper limit. Thermal derating is not required within this specified ambient range for the XC2C256-6FT256C.
Does XC2C256-6FT256C support in-system programming via JTAG?
Yes, the XC2C256-6FT256C fully supports IEEE 1149.1 JTAG-based in-system programming. This capability allows configuration bitstream updates and logic revisions without removing the device from the PCB. The XC2C256-6FT256C uses standard JTAG signals (TCK, TMS, TDI, TDO) and requires no auxiliary power or reset sequencing during ISP operations.
What I/O standards are supported by XC2C256-6FT256C?
The XC2C256-6FT256C supports LVTTL and LVCMOS I/O standards at 3.3 V and 2.5 V levels, configurable per I/O bank. Each bank can be independently set to either voltage, enabling seamless interfacing with mixed-voltage peripherals. The XC2C256-6FT256C does not support 1.8 V or 1.5 V I/O signaling-only core logic runs at 1.8 V.
Is XC2C256-6FT256C pin-compatible with other CoolRunner-II devices?
No, the XC2C256-6FT256C is not pin-compatible with smaller CoolRunner-II variants (e.g., XC2C32A or XC2C64A) due to its unique 256-ball FBGA footprint and higher I/O count. Pin compatibility exists only within the same 256-ball FT256 package variant-for example, XC2C256-7FT256C shares identical pinout but differs in speed grade.
What software tools are required to develop for XC2C256-6FT256C?
Xilinx ISE Design Suite (v14.7 or earlier) is the officially supported toolchain for synthesizing, fitting, and programming the XC2C256-6FT256C. AMD continues to provide legacy access to ISE binaries and documentation. The XC2C256-6FT256C is not supported in Vivado or newer AMD toolflows.
