XC2C32A-6VQG44I Architecture Overview
The XC2C32A-6VQG44I features Xilinx’s proven CoolRunner-II architecture, which consists of multiple functional blocks interconnected through an Advanced Interconnect Matrix (AIM).
Function Block Structure
Each Function Block in the XC2C32A-6VQG44I contains a 40×56 product term (P-term) Programmable Logic Array (PLA) and 16 macrocells. The AIM feeds 40 true and complement inputs to each Function Block, enabling complex combinational and sequential logic implementations.
Macrocell Configuration
The 32 macrocells in the XC2C32A-6VQG44I offer extensive configuration options including D or T flip-flop modes, D latch operation, global reset/preset capability, and multiple clock sources (both global and local product term types). Each macrocell can be configured independently for maximum design flexibility.
I/O Bank Architecture
The XC2C32A-6VQG44I provides two I/O banks that support multiple voltage standards simultaneously. This multi-voltage I/O capability simplifies interface design when connecting to devices operating at different voltage levels (3.3V, 2.5V, 1.8V, and 1.5V).
XC2C32A-6VQG44I Advanced Features
DataGATE Technology
The DataGATE feature allows designers to reduce power consumption by blocking signal switching on unused or idle signal paths. By mapping signals to the DataGATE function, overall dynamic power consumption decreases significantly without affecting active signal paths.
CoolCLOCK Technology
CoolCLOCK combines clock gating with a clock divider to enable high-performance synchronous operation at lower clock frequencies. This technology reduces total device power consumption while maintaining system performance requirements.
Clock Divider
The XC2C32A-6VQG44I includes circuitry to divide one externally supplied global clock (GCK2) by eight different selections, yielding both even and odd clock frequency divisions. This built-in clock management reduces external component count.
