Functional Description
The XC9536 architecture consists of two 36V18 Function Blocks, each containing 18 macrocells. These function blocks are interconnected through a FastCONNECT switch matrix that provides a low-skew, high-speed routing resource. Each macrocell can be individually configured for either combinatorial or registered operation, providing design flexibility.
The device features an advanced in-system programming (ISP) capability through the industry-standard 4-pin JTAG interface. This allows for field updates and configuration changes without removing the device from the circuit board. The XC9536 also supports full IEEE 1149.1 boundary scan testability for comprehensive system testing.
Design Considerations
Power Management
The XC9536 features advanced power management capabilities, including programmable power-down modes for unused function blocks. This helps reduce overall system power consumption in battery-operated applications.
Signal Integrity
With its 5 ns pin-to-pin delays, careful attention must be paid to signal integrity in high-speed designs. Proper PCB layout techniques, including controlled impedance traces and proper termination, are recommended for optimal performance.
Thermal Considerations
While the XC9536 has excellent power characteristics, designers should consider thermal management in high-density designs or elevated ambient temperature environments. Adequate airflow or heat sinking may be required in extreme conditions.
