Banks of LFSC3GA25E-7F900C

Input and output bank arrangement used in the LFSC3GA25E-7F900C FPGA showing how the device organizes its programmable I O resources into multiple voltage controlled regions. Eight banks are distributed around the device perimeter and each bank includes grouped connections for VCCIO supply, reference voltage inputs labeled VREF, termination voltage pins labeled VTT, and ground. This structure allows each bank to operate with independent electrical conditions so different signal standards can be supported on separate sides of the device. SERDES interface blocks appear near the upper banks to support high speed serial communication channels connected to nearby I O regions. The layout also identifies shared reference pins and power connections that define how external signals interact with the internal programmable logic through the banked I O structure.

Simplified Block Diagram of LFSC3GA25E-7F900C

Grid based internal layout of the LFSC3GA25E-7F900C FPGA showing the arrangement of programmable logic, memory blocks, clock resources, and high speed interface structures. Programmable function units form the central logic fabric where configurable digital circuits are implemented. Distributed sysMEM embedded block RAM sections provide internal data storage and buffering within the logic array. Programmable I O cells positioned along the device edges connect internal logic to external pins, with each programmable I O cluster containing multiple programmable I O connections. Quad SERDES blocks and physical coding sublayer interfaces appear near the top regions to support high speed serial communication. Structured ASIC blocks labeled MACO are integrated within the logic fabric to support specialized processing structures. Clock management resources labeled sysCLOCK analog PLLs and sysCLOCK DLLs are placed at the edges of the layout to generate and distribute timing signals across the programmable architecture.

Slice Diagram of LFSC3GA25E-7F900C

Internal structure of a logic slice used within the programmable function unit of the LFSC3GA25E-7F900C FPGA. Two LUT4 blocks perform combinational logic operations using four input signals labeled A, B, C, and D. Integrated carry logic supports arithmetic operations by linking carry input and carry output signals between adjacent slices. Flip flop or latch elements store output data from the logic stage, producing registered outputs labeled Q0 and Q1. Control inputs such as clock, clock enable, and set or reset signals regulate sequential operation of the storage elements. Routing connections on the left and right edges link the slice to the surrounding programmable interconnect network, allowing signals to enter from routing resources and return processed outputs back to the routing fabric.
