Advanced Architecture
The XC73108TM-70PC68C employs a unique Dual-Block architecture, which provides high speed operations via Fast Function Blocks and/or high density capability via High Density Function Blocks. Key architectural components include:
- Fast Function Blocks (FFBs): Provide fast, pin-to-pin speed and logic throughput for critical decoding and ultrafast state machine applications
- High-Density Function Blocks (FBs): Provide maximum logic density and system-level features to implement complex functions with predictable timing for adders and accumulators, wide functions and state machines requiring large numbers of product terms
- Universal Interconnect Matrix (UIM): Guarantees 100% interconnect of all internal functions with constant, short interconnect delays for all routing paths
Power Management
All XC7300 EPLDs include programmable power management features to specify high-performance or low-power operation on an individual Macrocell-by-Macrocell basis. Unused Macrocells are automatically turned off to minimize power dissipation.
