XC2C32A-4CP56C Architecture Overview
Function Block Structure
The XC2C32A-4CP56C consists of two Function Blocks interconnected by a low-power Advanced Interconnect Matrix (AIM). Each Function Block contains a 40×56 product-term PLA and 16 macrocells with configurable registers supporting D-type, T-type flip-flops, and D-latch modes.
Global Clock Resources
Three global clocks are available for synchronous operations across all Function Blocks. Additional local clock signals, clock-enable, and asynchronous set/reset controls can be generated using product terms on a per-macrocell basis.
In-System Programming
The XC2C32A-4CP56C supports IEEE 1149.1/1532 JTAG boundary-scan for easy in-system programming, prototyping, and testing without removing the device from the PCB.
