Xilinx XC95288XL-10TQG144I: A High-Performance, Low-Power CPLD

#XC95288XL-10TQG144I #Xilinx is a high-performance, low-power #CPLD (Complex Programmable Logic Device) that belongs to Xilinx’s XC9500XL series. This series of devices is manufactured using 3.3V low-voltage CMOS technology and supports 5V compatible I/O, aimed at digital systems requiring deterministic timing response, high-speed logic control, and low power characteristics.

Xilinx XC95288XL-10TQG144I: A High-Performance, Low-Power CPLD

Architecturally, the XC95288XL-10TQG144I is based on Xilinx’s FastFLASH CPLD technology, containing 288 macrocells, making it one of the larger capacity models in the series. Each macrocell consists of a Programmable Logic Array (PLA), a programmable AND gate array, asynchronous/synchronous flip-flops, and optional output control, enabling complex combinational and sequential logic. Macrocells are organized into Function Blocks (FB), with each logic block connected to other modules via a global programmable interconnect matrix (PIA), allowing for high-speed signal paths under predictable delay conditions.

The XC95288XL series offers up to approximately 6,000 equivalent gate logic capacity, supporting logic operation frequencies of up to 90 MHz, with propagation delays as low as approximately 5 ns, meeting the design requirements for medium to high-speed control applications. Each macrocell can be configured for combinational logic, registers, or tri-state output modes, with asynchronous or synchronous reset, clock enable, and independent operation across multiple clock domains achievable through software.

In terms of electrical characteristics, the core operating voltage of the XC95288XL-10TQG144I is 3.3V, but all I/O pins feature 5V tolerance, allowing direct interconnection with 5V TTL logic circuits. The I/O pins support various standards (LVTTL, LVCMOS, PCI, etc.), suitable for mixed-level system designs.

Regarding clock and timing performance, this device features a fixed, predictable delay structure, which is a significant characteristic of CPLDs compared to FPGAs. Due to the internal interconnect being a deterministic topology rather than a variable routing network, designers can precisely control signal delays and synchronization relationships, ensuring timing consistency, making it particularly suitable for control logic such as state machines, timing decoders, bus arbitration, and address decoding.

For configuration and development, the XC95288XL series devices utilize Flash-based non-volatile memory cells, supporting unlimited power-up cycles without the need for external configuration memory. Users can perform online programming and debugging via the JTAG interface, supporting the IEEE 1149.1 boundary scan standard, enabling system-level on-board debugging and testing.
